Free and Premium Juniper JN0-336 Dumps Questions Answers

The correct answers are A and D. Preparing Active Directory for JIMS requires creating limited-permission service accounts and assigning those accounts to the required Active Directory groups. Juniper’s JIMS deployment guidance states that you must create service accounts so JIMS can read from the defined directory services and identity producers; if PC probing is used, a service account is also required for that function. The same JIMS documentation includes a section named Configure Limited-Permission User Accounts, followed by Add Limited Permission User Accounts to Active Directory Groups.

Option A is correct because the JIMS preparation workflow commonly uses limited-permission accounts for event log access and PC probe access. Juniper identifies accounts such as JIMS-EventLogRemoteAccess and JIMS-PC-Probe in the Active Directory group-membership procedure. Option D is correct because those limited accounts must be added to the proper AD groups, including Event Log Readers and the groups required for remote management or PC probe operation.

Option B is wrong because the tested preparation requirement is not three limited-access accounts. Option C is wrong because JIMS should not be prepared by adding a broad full-access account; the course objective is least-privilege identity collection. Reference topics: JIMS, Active Directory preparation, limited-permission service accounts, Event Log Readers, PC probe account.

The correct answers are B and C. Juniper ATP Cloud improves security by delivering cloud-based threat detection, malware analysis, and enforcement integration with SRX Series Firewalls. Juniper describes ATP Cloud as using shared cloud intelligence so customers benefit from new threat intelligence in near real time. It also provides zero-day threat protection, machine-learning-based malware detection, inline malware blocking, and policy actions that can stop malware, quarantine infected systems, prevent data exfiltration, and disrupt lateral movement.

Option C is also correct because Juniper ATP Cloud uses dynamic analysis, commonly called sandboxing. In this process, a suspicious file is executed in a secure environment while tools monitor its activity. Juniper further explains that ATP Cloud uses deception techniques to make the sandbox appear like a real user environment, including simulated mouse movement, keystrokes, common software packages, realistic network access, stored credentials, and vulnerable OS areas. This encourages evasive malware to execute and reveal malicious behavior.

Option A is weaker and not the best answer because logging alone is not the key ATP Cloud security-improvement mechanism being tested. Option D is wrong because ATP Cloud is a threat-prevention service, not a performance-acceleration technology. Reference topics: ATP Cloud, malware analysis, dynamic sandboxing, machine learning, threat intelligence, inline malware blocking.

The correct answers are B and C. IDP false positives occur when legitimate traffic matches an attack signature or attack object incorrectly. One valid way to reduce false positives is to remove the problematic attack object from the IDP rule, especially when that object is not relevant to the protected application, server role, or traffic direction. Juniper defines attack objects as the items specified in IDP rules to identify malicious activity, so removing an irrelevant or noisy attack object directly reduces unwanted matches.

Option C is also correct because Juniper specifically recommends using an exempt rulebase when an IDP rule uses an attack object group containing attack objects that produce false positives or irrelevant log records. Exempt rules can exclude a specific source, destination, or source/destination pair from matching an IDP rule, preventing unnecessary alarms.

Option A is wrong because changing the action to a lower severity response does not reduce the false positive; it only changes what happens after the false match occurs. Option D is wrong because a terminal rule at the end of the rule base does not prevent earlier false-positive matches. Reference topics: IDP, attack objects, exempt rulebase, false-positive tuning, IDP rule matching.

The correct answers are B and D. In Junos SSL proxy terminology, client protection maps to SSL forward proxy. In a forward-proxy deployment, the SRX sits between internal clients and external SSL/TLS servers. The firewall intercepts the server certificate, generates a substitute certificate, signs it with the configured root CA, decrypts the SSL session for inspection, and then re-encrypts traffic toward the destination server. Juniper’s SSL proxy configuration table shows that a forward-proxy profile uses root-ca configured = Yes and server-certificate configured = No. It also states that configuring neither certificate type fails commit validation, while configuring both root-ca and server-certificate in the same profile is unsupported.

Option A is wrong because a server certificate is required for reverse proxy/server protection, not for client-protection forward proxy. Option C is wrong because without a trusted root CA, client browsers would not trust the certificates generated by the SRX during interception. Juniper separately notes that the root CA certificate is required for client browsers to trust certificates signed by the firewall. Reference topics: SSL Proxy, client protection, SSL forward proxy, root CA, server protection, SSL reverse proxy.

The correct answer is C. device policy rules. In Junos Space Security Director, a firewall rule that must apply uniquely to one SRX Series device belongs in the device-specific policy layer, not in global or group-level policy. Juniper’s Security Director documentation states that a device can have a device-specific policy and can also be part of multiple group policies; the rule processing order places policies applied before device-specific policies first, then device-specific policies, then policies applied after device-specific policies. Juniper also explains that rules applied before device-specific policies take priority and cannot be overridden, while rules applied after device-specific policies can be overridden by adding a rule in the device-specific policy.

Option A is wrong because all-devices prerules are global mandatory rules applied before device-specific policy, not unique device exceptions. Option B is wrong because group policy prerules apply to a group of devices, not one specific SRX. Option D is wrong because all-devices postrules are still global policy rules, although they can be overridden. For a unique policy requirement on one SRX device, device policy rules are the precise Security Director construct. Reference topics: Security Director, firewall policies, device-specific policies, policy rule precedence, global/group/device rule hierarchy.

The correct answers are B and D. The command output is from the SRX Series device: show services user-identification identity-management status. Under Primary server, the exhibit shows Address: 192.168.1.10, Port: 443, Connection method: HTTPS, and Connection status: Online. In Juniper Identity Management Service integration, the SRX is the client that connects to the configured primary JIMS server. Juniper’s configuration workflow specifically describes configuring “the IP address of the primary JIMS server” under services user-identification identity-management connection primary address, and the verification output shows that primary server address with its connection status.

Option A is wrong because 192.168.1.10 is listed under Primary server, not as the local SRX address. Option C is also wrong because this SRX command verifies the SRX-to-JIMS identity-management connection, not the backend JIMS-to-domain-controller connection. Domain controller reachability would be validated from JIMS or through JIMS-specific status/monitoring, not by this SRX-side output. The displayed Online state and OK (200) status confirm that the SRX successfully reached the JIMS HTTPS service and received a valid response. Juniper examples use the same status command to validate that the SRX identity-management connection to JIMS is online.

Reference topics: Identity-Aware Security Policies, Juniper Identity Management Service, SRX-to-JIMS connectivity, identity-management status verification.

The correct answers are B and C. The exhibit shows the command request security idp security-package install failing with: “Security package installation disabled temporarily due to invalid license.” In the IDP update workflow, the SRX must have a valid IDP/AppSecure-related license to install updated security packages. Juniper’s support guidance for an expired IDP license states that if the IDP license expires, attacks continue to be inspected, but IDP update installation is not allowed. That maps directly to this exhibit: the existing IDP engine and currently installed attack database can continue to inspect traffic, but the device cannot install the newer downloaded package until licensing is corrected.

Option A is wrong because expiration does not immediately stop all IDP inspection; it prevents installing new updates. Option D is not the best answer because the specific operational behavior shown is consistent with an invalid/expired license condition after attempting a package install, not proof that no license was ever installed. The practical remediation is to validate the installed license, renew or reinstall the correct IDP license, then retry the security-package installation. Reference topics: IDP licensing, security-package download/install, attack database updates, installed signature inspection behavior.

The correct answers are A and D. In IKEv1-based IPsec VPNs, there are two distinct negotiation phases. IKEv1 Phase 1 establishes the secure and authenticated IKE channel between peers. That means the IKE SA is built during Phase 1. Juniper describes Phase 1 as the negotiation of proposals for how to authenticate and secure the channel, including encryption algorithms, authentication algorithms, Diffie-Hellman group, and authentication method.

IKEv1 Phase 2 then uses that secure channel to negotiate the IPsec SAs that protect actual user traffic through the VPN. Juniper states that Phase 2 negotiates security associations to secure the data traversing the IPsec tunnel, and that the Phase 2 proposal includes the security protocol, such as ESP or AH, plus the selected encryption and authentication algorithms. Option B is wrong because IKEv1 SAs are not established in Phase 2; Phase 2 creates IPsec SAs. Option C is wrong because Phase 1 does not create the data-plane IPsec SA; it creates the secure IKE control channel used for Phase 2 negotiation. Reference topics: IPsec VPN, IKEv1 Phase 1, IKE SA, IKEv1 Phase 2, IPsec SA, ESP/AH proposals.

The correct answer is D. exempt. In Junos IDP, the exempt rulebase is specifically used to prevent selected traffic from triggering known false-positive detections. Juniper’s IDP documentation explains that exempt rules can be configured when an IDP policy generates false positives for a particular attack object, source, destination, or traffic pattern. The exempt rulebase lets the administrator exclude matching traffic from attack detection while still allowing the rest of the IDP policy to inspect other traffic normally.

Option A, IPS, is wrong because the IPS rulebase is the main inspection rulebase used to detect and act on attacks. It is where attack objects and actions are commonly applied, but it is not the rulebase designed to eliminate false positives. Option B, monitor, is not the correct false-positive elimination mechanism. Monitoring can help observe behavior, but it does not exempt traffic from matching an attack object. Option C, signature, is wrong because signatures are attack-detection patterns, not a rulebase type used to suppress false positives. The operational correction for noisy or irrelevant matches is to create an exempt rule for the specific trusted source, destination, or attack object. Reference topics: IDP rulebases, exempt rulebase, false-positive tuning, attack objects, IPS inspection.

The correct answers are B, D, and E. Security Director device onboarding depends on management reachability and valid administrative access. Juniper’s device discovery documentation states that Junos Space discovers network devices using SSH, with optional ping and SNMP, and connects to the physical device to retrieve running configuration and status information. It also explains that device authentication uses administrator login credentials, SSH credentials, SNMP settings, or keys depending on the discovery method.

Option E is required because Security Director must target a reachable management IP address or hostname. Juniper’s discovery-profile workflow explicitly uses the target IP address, hostname, IP range, or subnet to locate devices. Option D is required because invalid username/password or insufficient privileges prevent discovery and management; Juniper’s device-management guidance identifies credentials as required input for discovering devices. Option B is required because onboarding uses SSH, so the correct SSH service and port must be reachable. Juniper’s device access procedure explicitly includes a Port field for the SSH connection.

Option A is wrong because chassis serial number is not the normal troubleshooting field for Security Director discovery. Option C is wrong because active security policies do not determine whether Security Director can initially discover and onboard the device. Reference topics: Security Director, device discovery, SSH access, management IP reachability, authentication credentials.

The correct answers are A and B. The exhibit shows show chassis cluster statistics. Under Control link statistics, Control link 0 has heartbeat packets sent and received, with heartbeat packet errors: 0. That is the clearest indication that the control link is operating normally. Juniper describes chassis-cluster control-plane verification as checking control-link heartbeat packets sent and received, along with heartbeat errors. If both send and receive counters are incrementing and errors are zero, the control link is functioning.

Option A is also correct because under Fabric link statistics, Child link 0 shows probes sent and probes received. Juniper uses fabric-link probe counters to verify fabric-link operation; nonzero sent and received probe counters indicate that the link is participating in fabric monitoring. Option C is not the safest conclusion from this exhibit alone. Child link 1 shows zero probes sent and received, but the output does not prove that a second fabric child link is configured and failing; it could simply be unused or not configured in this deployment. Option D is directly contradicted by the healthy heartbeat counters. Reference topics: HA Clustering, chassis cluster statistics, control-link heartbeat, fabric-link probes, cluster health verification.

The correct answers are B and D. A terminal rule is specifically designed to stop further rule evaluation. Juniper states that the IDP rule-matching algorithm normally checks traffic against all matching rules in the rulebase, but when a terminal rule matches the source, destination, zones, and application, IDP does not continue to check subsequent rules for that same traffic. Juniper also warns that traffic matching a terminal rule is not compared to later rules even if it does not match the attack object inside that terminal rule.

Option D is also correct because the Ignore Connection action stops scanning traffic for the rest of the connection if an attack match is found. Juniper defines Ignore Connection as disabling the rulebase for that specific connection after a match. Option A is wrong because a close action closes the connection by sending reset behavior, but it is not the rule-processing control mechanism being tested. Option C is a trap: the exempt rulebase is used to suppress known false positives after an IPS rule match, but the two direct mechanisms that end IDP rule processing are terminal rule matching and ignore connection. Reference topics: IDP rulebases, terminal rules, Ignore Connection action, rule-matching algorithm, false-positive exemption.

The correct answer is A. by granting access based on user roles or identities. Juniper identity-aware firewall moves enforcement beyond simple IP-address-based policy by associating traffic with authenticated users, groups, devices, and roles. Juniper states that identity parameters can be used to configure security policies so that policies provide the appropriate level of access to authenticated users. It further explains that identity helps secure access to resources based on username, roles, and groups, and that firewalls can create and enforce rules based on user identity rather than only an IP address.

This directly supports compliance because regulated environments usually require least-privilege access, auditable user-based control, and role-based authorization. Option B is wrong because identity-aware security might simplify policy operations in some cases, but network architecture simplification is not its compliance function. Option C is wrong because capacity expansion has no direct relationship to identity-based regulatory enforcement. Option D is too vague and not the mechanism being tested; confidentiality is a security goal, but identity-aware firewall enforces access decisions by mapping traffic to users and groups. Reference topics: Identity-Aware Security Policies, user identity, role-based access control, group-based policy enforcement, authentication table.

The correct answers are C and D. Juniper Secure Connect is Juniper’s remote-access VPN client for SRX Series Firewalls. Juniper describes it as a flexible SSL VPN and IPsec application that gives remote workers secure access to corporate and cloud-protected resources. That directly supports option D, because SSL VPN provides a connection method that is useful when traditional IPsec ports are restricted or blocked. Juniper’s Secure Connect guide also states that enabling SSL VPN gives the client flexibility in connecting to SRX Series Firewalls and that SSL VPN is enabled by default.

Option C is also correct because Juniper Secure Connect supports external authentication, allowing users to authenticate with enterprise identity systems rather than relying only on local firewall credentials. Juniper’s external authentication procedure notes that this method lets users use the same username and password as their domain login and is recommended for authenticating users.

Option A is not the best answer because having a client application is not the specific connection/authentication flexibility being tested. Option B is wrong because Kerberos is not the stated Secure Connect authentication method in this context. Reference topics: Juniper Secure Connect, remote-access VPN, SSL VPN, IPsec, external authentication.

The correct answers are C and D. The cSRX is Juniper’s containerized SRX firewall, intended for lightweight virtual and container environments where rapid deployment and high density matter. Juniper’s cSRX documentation lists supported security capabilities including basic firewall policy, NAT, Intrusion Detection and Prevention, content security/UTM functions, ATP Cloud, SSL Proxy, AppID, AppFW, and AppTrack. That supports option C, because cSRX provides SRX security services in a containerized footprint rather than requiring a full VM-based firewall appliance.

Option D is also correct because Juniper identifies the cSRX’s small footprint and minimum resource reservation requirements as key benefits; it is designed to scale more densely than VM-based firewall options. Juniper’s Day One cSRX guide specifically identifies faster deployment, a small footprint, and reduced resource consumption as major benefits. Option A is not the best answer for this exam item because the question asks for cSRX deployment benefits, not merely forwarding-mode support. Option B is wrong because the tested cSRX advantage is not a default three-zone configuration. Reference topics: cSRX container firewall, virtual SRX deployment, firewall/NAT/IPS/UTM services, lightweight resource footprint.

The correct answers are A, C, and E. During Security Director device discovery, Junos Space first finds and connects to the managed device, then synchronizes the device inventory and configuration into the Junos Space database. Juniper’s Security Director documentation states that discovery uses a discovery profile containing target information, authentication credentials, probes, and SSH fingerprints. During discovery, Junos Space connects to the physical device and retrieves the running configuration and status information. It also states that Junos Space uses SSH, with optional ping and SNMP, to discover network devices.

Option B is wrong because device discovery is not a reboot operation. Rebooting would be disruptive and is not part of onboarding a managed SRX into Security Director. Option D is wrong because discovery does not automatically inject a local superuser into the SRX configuration. Security Director authenticates using credentials supplied in the discovery profile; it does not create privileged local accounts as a discovery action. The tested workflow is management-plane discovery: connect, authenticate, retrieve inventory/status, and import configuration state. Reference topics: Security Director, device discovery, discovery profiles, SSH, running configuration import, device status synchronization.

The correct answer is B. LDAP. In Juniper identity-aware firewall deployments, the SRX Series Firewall integrates with Microsoft Active Directory so that user and group information can be used in security policy decisions. Juniper’s Active Directory identity-source documentation states that the LDAP protocol helps identify the groups to which users belong, and that username and group information are queried from the LDAP service running on the Active Directory domain controller. It also explains that the device uses Lightweight Directory Access Protocol to obtain user and group information required for Active Directory identity-source operation.

Option A, SSH, is wrong because SSH is a device management protocol, not the protocol SRX uses to query Active Directory user/group membership. Option C, DNS, is wrong because DNS can resolve names but does not provide Active Directory group mapping to the firewall. Option D, NETCONF, is wrong because NETCONF is used for network device configuration and automation, not Windows domain-controller identity queries. In a complete identity-aware firewall workflow, SRX may also use WMI/DCOM-related mechanisms to read Windows event-log data, but among the available protocol choices, LDAP is the correct answer because it is the directory protocol used to query user and group information. Reference topics: Active Directory identity source, LDAP, domain controller communication, user and group mapping.

The correct answers are A, C, and E. Junos Space Security Director supports policy hierarchy and policy management at device, group, and global/all-devices levels. A device policy is created for a specific device and is used when a unique firewall policy must be pushed to one SRX Series Firewall. A group policy is shared across multiple devices and is used when the same policy configuration must be applied consistently to a set of managed firewalls. Juniper’s Security Director documentation explicitly describes device policy and group policy behavior, including the fact that device-specific policies are evaluated within the broader policy-ordering model.

The third correct policy type is global, often represented in Security Director workflows as all-devices/global policy behavior. Juniper Security Director product material describes granular control over global, group, and device-level firewall policies, which maps directly to the options in this question. Option B, local, is not the Security Director policy type being tested; local configuration may exist on an SRX, but it is not one of the Security Director policy hierarchy types listed here. Option D, universal, is also not a Junos Space Security Director policy type. Reference topics: Security Director, global policy, group policy, device policy, firewall policy hierarchy, centralized SRX policy management.

The correct answer is B. The node with the highest priority will become a primary node. In an SRX chassis cluster, redundancy groups determine which node is primary and which node is secondary. Juniper states that when priorities are assigned to nodes in a redundancy group, the node with the higher configured priority is initially designated as the primary, while the other node becomes secondary. This is the direct mechanism an administrator uses to influence primary-node selection for a redundancy group.

Option A is wrong because the burnt-in address is not the administrative method used to designate the primary node. BIA can be part of deterministic hardware identity behavior, but primary election is controlled through redundancy-group priority, preemption behavior, and failover state. Option C is the opposite of Juniper behavior; the lower-priority node does not win the election. Option D is also wrong because a priority of one is still a valid low priority. The ineligible value is 0, and Juniper specifically warns about failover behavior involving nodes with priority 0 because such nodes are not ready to accept traffic.

Reference topics: HA Clustering, redundancy groups, node priority, primary/secondary election, preemption, chassis cluster failover.

The correct answer is D. maintaining a centralized authentication table. Juniper Identity Management Service, or JIMS, is used with SRX Series Firewalls to collect user-identity information from identity sources such as Microsoft Active Directory, domain controllers, and Exchange servers, then provide that identity data to SRX enforcement points. Juniper describes JIMS as storing IP address, username, and group-relationship information in its cache and generating authentication entries used for user-based or group-based access control on SRX firewalls. Juniper’s Identity-Aware Firewall documentation also states that the authentication table contains the IP address, username, and group mapping information used as the authentication source.

Option A is wrong because JIMS is not an email-encryption service. Option B is wrong because malicious-code logging belongs to security inspection features such as antivirus, IDP, or ATP workflows, not JIMS. Option C is wrong because network data encryption is handled by technologies such as IPsec VPN or SSL/TLS, not identity management. JIMS exists to centralize identity-to-IP mapping so identity-aware security policies can match users and groups instead of relying only on source IP addresses. Reference topics: Identity-Aware Security Policies, JIMS, authentication table, user-to-IP mapping, group-based policy enforcement.
