JN0-336 Exam Dumps : Security, Specialist (JNCIS-SEC)

The correct answers are B and D. IKE Phase 2 negotiates the IPsec security associations used to protect actual user data through the VPN tunnel. Juniper explains that after Phase 1 establishes a secure authenticated channel, Phase 2 negotiates SAs for the data transmitted through the IPsec tunnel. A Phase 2 proposal includes the IPsec security protocol, which is either ESP or AH, along with selected encryption and authentication algorithms. In the wording of this question, that maps to the tunnel/security protocol property.

Option D, Perfect Forward Secrecy, is also correct because Phase 2 proposals can specify a Diffie-Hellman group when PFS is desired. PFS forces a new DH key exchange for Phase 2 keys so that compromise of earlier keying material does not expose later IPsec encryption keys. Option A is wrong because routing protocols are not negotiated by IKE Phase 2; routing is handled separately over or toward the tunnel interface. Option C is wrong because aggressive mode is an IKEv1 Phase 1 exchange mode, not a Phase 2 property. Juniper specifically states that Phase 2 always uses quick mode in IKEv1. Reference topics: IKE Phase 2, IPsec SA negotiation, ESP/AH, Perfect Forward Secrecy, quick mode.

The correct answers are C and D. Once the SSL proxy profile already exists, the SRX still needs a security policy that matches the SSL/TLS traffic and applies the SSL proxy profile as an application service. Juniper’s SSL proxy configuration procedure explicitly shows creating the security policy match criteria and then applying the SSL proxy profile with then permit application-services ssl-proxy profile-name. It also states that SSL forward and reverse proxy require the profile to be configured at the firewall rule level.

Option D is correct because SSL proxy is not an end goal by itself; it decrypts SSL/TLS traffic so Layer 7 security services can inspect it. Juniper states that decrypted SSL traffic is available for security services and provides examples where the SSL proxy profile and a Content Security/UTM policy are both attached to the same security policy. Option A is wrong because host-inbound-traffic HTTPS controls HTTPS access to the SRX itself, not transit SSL proxy inspection. Option B is wrong because SSL proxy profiles are not referenced under a security zone for this function; they are applied under the matching security policy. Reference topics: SSL Proxy, SSL proxy profile, security policy application-services, Layer 7 inspection, UTM/IDP/ATP integration.

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.
