Fortinet NSE7_PBC-7.2 Dumps

For configuring the failover settings on a FortiGate active-passive SDN connector solution in Microsoft Azure, the two mandatory settings required after the initial deployment are:

A.Subscription-id

D.Resource group name

• Subscription ID:This is a unique identifier for your Azure subscription under which all resources are created and billed. FortiGate needs this to interact with the Azure resources associated with that subscription.
• Resource Group Name:A resource group in Azure is a container that holds related resources for an Azure solution. The SDN connector requires the resource group name to correctly identify and manage the resources it should control, especially in a failover scenario.

References:The requirement for these specific details is found in Azure's best practices for resource management and Fortinet's documentation on deploying and configuring FortiGate appliances in Azure environments.

The three settings that should be checked while troubleshooting this problem are:

• Ensure FortiGate port4 can resolve DNS. This is because the Azure SDN connector requires DNS resolution to communicate with the Azure API1. If the FortiGate port4 cannot resolve DNS, the SDN connector will not be able to retrieve the Azure resources and display them in the GUI.
• Ensure FortiGate portl has internet access. This is because the Azure SDN connector requires internet access to communicate with the Azure API1. If the FortiGate portl does not have internet access, the SDNconnector will not be able to connect to the Azure cloud and display an error in the CLI.
• Ensure IP address 169.254.169_254 is not blocked. This is because the Azure SDN connector uses this IP address to obtain metadata information from the Azure instance2. If this IP address is blocked by a firewall policy or a network ACL, the SDN connector will not be able to get the required information and display an error in the CLI.

When using an AWS CloudFormation template to add a new spoke to an existing transit VPC environment, the necessary components are:

• The BGPASN value used for the transit VPC (Option C):BGP Autonomous System Number (ASN) is required for setting up BGP routing between the transit VPC and the new spoke. This number uniquely identifies the system in BGP routing and is crucial for correct routing and avoiding routing conflicts.
• The tag value of the spoke (Option D):Tags in AWS are used to identify and manage resources. The tag value assigned to a spoke VPC helps in organizing, managing, and locating the VPC within the larger AWS environment. Tags are essential for automation scripts and policies that depend on specific identifiers to apply configurations or rules.

References:AWS CloudFormation and AWS Transit Gateway documentation provide guidance on the use of BGPASN and tags for managing and automating VPC deployments effectively.

B. Add route destination 0.0.0.0/0 to target the transit gateway. This will ensure that the Customer VPC FortiGate VM sends all the outbound internet traffic through the Security VPC, where it can be inspected by the Security VPC FortiGate VMs1. The transit gateway is a network device that connects multiple VPCs and on-premises networks in a hub-and-spoke model2. D. Deploy an internet gateway, associate an EIP in the private subnet, edit route tables, and add a new route destination 0.0.0.0/0 to the target internet gateway. This will allow inbound HTTPS access to the Customer VPC FortiGate VM from the internet, by creating a public route for the private subnet where the FortiGate VM is located3. An internet gateway is a service that enables communication between your VPC and the internet4. An EIP is a public IPv4 address that you can allocate to your AWS account and associate with your resources. E. Deploy an internet gateway, associate an EIP in the public subnet, and attach the internet gateway to the Customer VPC. This will also allow inbound HTTPS access to the Customer VPC FortiGate VM from the internet, by creating a public route for the public subnet where the FortiGate VM is located3. This is an alternative solution to option D, depending on which subnet you want to use for the FortiGate VM.

The other options are incorrect because:

• Adding a route with your local internet public IP address as the destination and target transit gateway will not allow inbound HTTPS access to the Customer VPC FortiGate VM from the internet, because it will only apply to traffic coming from your specific IP address, not from any other source on the internet1. Moreover, it will not ensure that the outbound internet traffic goes through the Security VPC, because it will only apply to traffic going to your specific IP address, not to any other destination on the internet1.
• Adding a route with your local internet public IP address as the destination and target internet gateway will not allow inbound HTTPS access to the Customer VPC FortiGate VM from the internet, because it will bypass the Security VPC and send the traffic directly to the Customer VPC1. Moreover, it will not ensure that the outbound internet traffic goes through the Security VPC, because it will only apply to traffic going to your specific IP address, not to any other destination on the internet1.

According to the AWS documentation for Transit Gateway, a Transit Gateway is a network transit hub that connects VPCs and on-premises networks. To route traffic from Linux instances to the TGW, you need to do the following steps:

• In the TGW route table, associate two attachments. An attachment is a resource that connects a VPC or VPN to a Transit Gateway. By associating the attachments to the TGW route table, you enable the TGW to route traffic between the VPCs and the VPN.
• In the main subnet routing table in VPC A and B, add a new route with destination 0_0.0.0/0, next hop TGW. This route directs all traffic from the Linux instances to the TGW, which can then forward it to the appropriate destination based on the TGW route table.

The other options are incorrect because:

• In the TGW route table, adding route propagation to 192.168.0 0/16 is not necessary, as this is already the default route for the TGW. Route propagation allows you to automatically propagate routes from your VPC or VPN to your TGW route table.
• In the main subnet routing table in VPC A and B, adding a new route with destination 0_0.0.0/0, next hop Internet gateway (IGW) is not correct, as this would bypass the TGW and send all traffic directly to the internet. An IGW is a VPC component that enables communication between instances in your VPC and the internet.

The reason the administrator cannot access the EC2 instance could be:

D.The directory location of the .pem file is incorrect.

• SSH Key Location:When initiating an SSH connection to an AWS EC2 instance, you must specify the private key file (.pem file) location that corresponds to the public key used when the instance was launched. The error "Warning: Identity file Staging-key.pem not accessible: No such file or directory" indicates that the SSH client cannot find the .pem file at the specified location.
• Correct File Path:The administrator needs to ensure that the path to theStaging-key.pemfile is correctly specified when running the SSH command. If the file is not in the current directory from which the command is executed, the full or relative path to the file must be provided.

References:This behavior is in line with standard SSH connection practices and AWS guidelines for accessing EC2 instances. It is a common issue that occurs when the private key file is not located in the directory from which the SSH command is being executed or the path provided is incorrect.

• A is incorrect because the FortiGate public IP is not the next-hop for all the traffic. The FortiGate public IP is only used for incoming traffic from the internet. The Azure load balancer distributes the incoming traffic to the active FortiGate VM based on a health probe123. The FortiGate public IP is not used for outgoing traffic or internal traffic.
• B is correct because an internal load balancer listener is the next-hop for outgoing traffic. The internal load balancer listener is configured with a floating IP address that is assigned to the active FortiGate VM. The internal load balancer listener also has a health probe to monitor the status of the FortiGate VMs123. The internal load balancer listener forwards the outgoing traffic to the internet through the public load balancer.
• C is incorrect because you do not need to add a route to the Microsoft VIP used for the health check. The Microsoft VIP is an internal IP address that is used by the Azure load balancer to send health probes to the FortiGate VMs123. The Microsoft VIP is not reachable from outside the Azure network and does not require any routing configuration on the FortiGate VMs.
• D is correct because a dedicated management interface can be used for load balancing. In this deployment, port4 is used as a dedicated management interface that connects to the management network3. The dedicated management interface can be used to access the FortiGate VMs for configuration and monitoring purposes. The dedicated management interface can also be used to synchronize the configuration and session information between the primary and secondary devices in an HA cluster2.

Considering the situation where the administrator is unable to access the FortiGate VM using its public IP address and no traffic is reaching the FortiGate's external interface, the administrator should check:

D.Check the inbound network security group rules.

• Network Security Group Rules:AWS uses security groups as a virtual firewall that controls inbound and outbound traffic to AWS resources such as EC2 instances. If the FortiGate VM’s public interface is not receiving HTTPS or SSH traffic, it's likely because the inbound security group rules associated with that interface are not allowing access on the necessary ports (HTTPS - port 443, SSH - port 22).
• Troubleshooting:The administrator should verify that the security group rules for the FortiGate VM’s network interface allow inbound traffic on the specific ports used for management access. If these rules are absent or misconfigured, the intended traffic will be blocked, resulting in the inability to connect.

References:The role of security groups in network traffic management is a core concept in AWS and is outlined in AWS documentation. Checking security group rules is a standard troubleshooting step when dealing with connectivity issues to AWS resources.

In this scenario, the issue is caused by the Azure service principle account nothaving a contributor role. This is required for the FortiGate HA floating IP to work properly. Without this role, the new primary device will not have the previous primary device floating IP address after failover. References: Fortinet Public Cloud Security knowledge source documents or study guide.

For deploying a FortiGate VM using Terraform in AWS, the administrator must use:

B.Use the Name of the key pair.

• Terraform and AWS SSH Keys:When deploying instances in AWS using Terraform, it is required to specify the name of the SSH key pair to enable key-based authentication to the instance post-deployment.
• Configuration Syntax:The variablekeynamewithin the Terraform configuration should match the exact name of the SSH key pair as it is stored in AWS. This ensures that Terraform can reference the correct key during the deployment process to set up SSH access to the FortiGate VM.
• Terraform Variables:Thevariable "keyname"block in the Terraform configuration will look for the key pair name as it should be declared in theterraform.tfvarsfile or passed as a variable during execution. This does not require the key pair's ID or fingerprint, just its name.

References:The need for the SSH key pair's name in Terraform configurations for AWS deployments is outlined in the Terraform AWS Provider documentation, which specifies how resources should be provisioned using Terraform.

When an administrator decides to use the 'Use managed identity' option for the FortiGate SDN connector with Microsoft Azure and faces a connection failure, the correct action to take is:

C.Make sure to enable the system assigned managed identity on Azure.

• Managed Identity Configuration:The system assigned managed identity is a feature in Azure that provides an identity for the Azure service instance (in this case, the FortiGate SDN connector) within Azure Active Directory and eliminates the need for credentials to be stored in the configuration.
• Troubleshooting Connection Issues:If the SDN connector is failing to connect, it could be because the system assigned managed identity has not been enabled or configured properly in Azure for the FortiGate service.

References:Azure documentation on managed identities explains the need to enable and configure this feature for services to authenticate and interact securely with Azure resources.

To keep track of sensitive data files located in AWS S3 buckets and protect them from malware, the administrator should use:

C.FortiCNP DLP policies.

• Data Loss Prevention (DLP):DLP policies are designed to detect and prevent unauthorized access or sharing of sensitive data. In the context of AWS S3, DLP policies can be used to scan for sensitive information stored in S3 objects and enforce protective measures to prevent data exfiltration or compromise.
• FortiCNP Integration:FortiCNP is Fortinet’s cloud-native protection platform that offers security and compliance solutions across cloud environments. By applying DLP policies within FortiCNP, the administrator can ensure sensitive data within S3 is monitored and protected consistently.

References:Fortinet's FortiCNP documentation provides information on implementing DLP policies within cloud environments, highlighting the capabilities for protecting sensitive data within cloud storage services like AWS S3.

Network ACLs are stateless, and they evaluate each packet separately based on the rules that you define. The rules are processed in order, starting with the lowest numbered rule1. If the traffic matches a rule, the rule is applied and no further rules are evaluated1. Therefore, if you want to allow SSH traffic to a subnet, you must create a new allow SSH rule above rule number 5, which denies SSH and telnet traffic. Otherwise, the deny rule will take precedence and block the SSH traffic.

The other options are incorrect because:

• Creating a new allow SSH rule below rule number 5 will not allow SSH traffic, because the deny rule will be evaluated first and block the traffic.
• Creating a new allow SSH rule anywhere in the network ACL rule base will not guarantee that SSH traffic will be allowed, because it depends on the order of the rules. If the allow SSH rule is below the deny rule, it will not be effective.
• You cannot rely on the default security group rule to allow SSH traffic to the subnet, because network ACLs act as an additional layer of security for your VPC. Even if your security group allows SSH traffic, your network ACL must also allow it. Otherwise, the traffic will be blocked at the subnet level.

The two best connection solutions available between your company headquarters, branch sites, and the Azure vWAN hub are A. ExpressRoute and E. VPN Gateway.

According to the Azure documentation for Virtual WAN, ExpressRoute and VPN Gateway are two of the supported connectivity options for connecting your on-premises sites and Azure virtual networks to the Azure vWAN hub1. These options provide secure, reliable, and high-performance connectivity for your network traffic.

ExpressRoute is a service that lets you create private connections between your on-premises sites and Azure.ExpressRoute connections do not go over the public internet, and offer more reliability, faster speeds, lower latencies, and higher security than typical connections over the internet2.

VPN Gateway is a service that lets you create encrypted connections between your on-premises sites and Azure over the internet using IPsec/IKE protocols.VPN Gateway also supports point-to-site VPN connections for individual clients using OpenVPN or IKEv2 protocols3.

The other options are incorrect because:

• GRE tunnels are not a supported connectivity option for Azure vWAN. GRE is a protocol that encapsulates packets for tunneling purposes.GRE tunnels are established between the connect attachment and your appliance in Azure vWAN4.
• SSL VPN connections are not a supported connectivity option for Azure vWAN. SSL VPN is a type of VPN that uses the Secure Sockets Layer (SSL) protocol to secure the connection between a client and a server.SSL VPN is not compatible with the Azure vWAN hub5.
• An L2TP connection is not a supported connectivity option for Azure vWAN. L2TP is a protocol that creates a tunnel between two endpoints at the data link layer (Layer 2) of the OSI model.L2TP is not compatible with the Azure vWAN hub.

Based on the provided exhibit showing an active-passive FortiGate High Availability (HA) pair with external and internal Azure load balancers and without the use of an SDN connector, the administrator should implement a Probe IP address with two static routes (Option B).

• Probe IP Address:Azure load balancers use a health probe to determine the health of the instances in the backend pool. The health probe ensures that the load balancer only directs traffic to the active (primary) FortiGate in an HA pair.
• Two Static Routes:Given that this is an active-passive setup, static routing should be used to ensure deterministic traffic flow. Two static routes would be configured to ensure that traffic can flow to the active unit and be correctly routed to the protected subnets in failover scenarios.

References:The recommendation for using a Probe IP address with static routes is based on Azure's best practices for load balancer configuration, particularly for HA scenarios, as well as on Fortinet's HA documentation for clouddeployments. This setup ensures high availability while allowing proper traffic distribution based on the health probe's findings.

According to the AWS documentation for Transit Gateway, a transit gateway is a network transit hub that connects VPCs and on-premises networks. A transit gateway route table is a set of rules that determines how traffic is routed among the attachments to the transit gateway1.

A transit gateway can have multiple route tables, and you can associate different attachments with different route tables. This allows you to control how traffic is routed between your VPCs and VPNs based on your network design and security requirements1.

The other options are incorrect because:

• Both the TGW attachment and propagation must be in the same TGW route table is not true. You can associate an attachment with one route table and enable propagation from another attachment to a different route table. This allows you to separate the routing domains for your attachments1.
• A TGW attachment can be associated with multiple TGW route tables is not true. You can only associate an attachment with one route table at a time. However, you can change the association at any time1.
• The TGW default route table cannot be disabled is not true. You can disable the default route table by deleting all associations and propagations from it. However, you cannot delete the default route table itself1.

This is because the Linux1 EC2 instance is not accessible directly from the internet using its public IP address in AWS.

An internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet. Without an internet gateway, the Linux1 EC2 instance cannotreceive or send traffic to or from the internet, even if it has a public IP address assigned to it.

To fix this issue, you need to attach an internet gateway to the Spoke VPC A and configure a route table that directs internet-bound traffic to the internet gateway. You also need to ensure that the Linux1 EC2 instance has a security group that allows inbound and outbound traffic on the desired ports.
