NSE7_PBC-7.2 Questions and Answers

The correct answer is B and C. Both landing subnets in the spoke VPCs must have a 0.0.0.0/0 traffic route to the TGW. Both landing subnets in the security VPC must have a 0.0.0.0/0 traffic route to the FortiGate port2.

According to the AWS documentation for Transit Gateway, a transit gateway is a network transit hub that connects VPCs and on-premises networks. To send outbound traffic from the Linux instances to the internet through the security VPC, you need to do the following steps:

In the main subnet routing table in the spoke VPCs, 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.

In the main subnet routing table in the security VPC, add a new route with destination 0.0.0.0/0, next hop FortiGate port2. This route directs all traffic from the TGW to the FortiGate internal interface, where it can be inspected and allowed by the FortiGate policies.

The other options are incorrect because:

Adding a 0.0.0.0/0 traffic route to the Internet Gateway (IGW) in the spoke VPCs is not correct, as this would bypass the TGW and the security VPC and send all traffic directly to the internet.

Adding a 0.0.0.0/0 traffic route to the TGW in all the VPCs is not necessary, as only the spoke VPCs need to send traffic to the TGW. The security VPC needs to send traffic to the FortiGate port2.

When deploying resources in multiple places and regions in the public cloud using Terraform, the most efficient way is:

A. Use multiple terraform.tfvars files with a variables.tf file.

Terraform.tfvars File: This file is used to assign values to variables defined in your Terraform configuration. By having multiple .tfvars files, you can define different sets of values for different deployments, such as for different regions or environments, without changing the main configuration.

Variables.tf File: This file contains the definition of variables that will be used within your Terraform configuration. It works in conjunction with terraform.tfvars files, allowing you to parameterize your configuration so that you can deploy the same template in multiple environments with different variables.

References: This method is outlined in Terraform's official documentation and is a best practice for reusing code for different environments in infrastructure as code (IaC) deployments.

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.

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 cannot receive 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.

The correct answer is C and D. FortiGate NGFW can inspect north-south container traffic with label aware policies and FortiGate NGFW and FortiSandbox can be used to secure container traffic.

According to the Fortinet documentation for container security1, FortiGate NGFW can provide the following benefits for securing container infrastructure:

It can inspect north-south traffic between containers and external networks using label aware policies, which allow for dynamic policy enforcement based on Kubernetes labels and metadata.

It can integrate with FortiSandbox to provide advanced threat protection for container traffic, by sending suspicious files or URLs to a cloud-based sandbox for analysis and detection.

It can leverage FortiGuard Security Services to provide real-time threat intelligence and updates for container traffic, such as antivirus, web filtering, IPS, and application control.

The other options are incorrect because:

FortiGate NGFW cannot be placed between each application container for north-south traffic inspection, as this would create unnecessary complexity and overhead. Instead, FortiGate NGFW can be deployed at the edge of the container network or as a sidecar proxy to inspect traffic at the ingress and egress points.

FortiGate NGFW cannot connect to the worker node and protect the container, as this would not provide sufficient visibility and control over the container traffic. Instead, FortiGate NGFW can leverage the native Kubernetes APIs and services to monitor and secure the container traffic.

A VPC attachment is the type of attachment that allows you to connect a VPC to a TGW and advertise routes through BGP. A VPC attachment creates a VPN connection between the VPC and the TGW, and enables dynamic routing with BGP. A connect attachment is used to connect a VPN or Direct Connect gateway to a TGW. A route attachment is not a valid type of attachment for TGW. A GRE attachment is used to connect a FortiGate device to a TGW using GRE tunnels. References:

For Transit Gateway Connect peers in an IPv4 BGP configuration, the correct statements are:

The inside CIDR blocks are used for BGP peering (Option A): In a BGP configuration for Transit Gateway Connect, the inside CIDR blocks, typically within the 169.254.0.0/16 range, are designated for the BGP peering connections. These blocks are reserved for internal network protocols and are commonly used in AWS for automatic IP address assignment within managed networking services.

You must specify a /29 CIDR block from the 169.254.0.0/16 range (Option C): It is a requirement to specify a /29 CIDR block within the 169.254.0.0/16 range for setting up the network interfaces that facilitate BGP peering. This specific range allows for the necessary number of IP addresses to establish BGP sessions effectively between the transit gateway and on-premises or other virtual appliances.

References: These practices are in line with AWS guidelines for Transit Gateway Connect, which stipulate the use of specified CIDR blocks for internal networking and BGP configurations, ensuring seamless connectivity and routing management.

When adding the Amazon Web Services (AWS) account to the FortiCNP, you must follow these three mandatory configuration steps:

Add AWS accounts through FortiCNP. This is the first step to enable cloud protection for your AWS account. You can add one or multiple accounts automatically or manually. You need to provide the AWS account ID and a name for the account. You also need to select the optional permissions to be granted to FortiCNP as needed1.

Accept FortiCNP to create CloudTrail for the account. This is required for FortiCNP to collect and analyze the AWS API calls and events. You can choose to let FortiCNP create a CloudTrail for the account or use an existing one. You also need to specify the aggregation region for the CloudTrail1.

Launch the CloudFormation template. This is required for FortiCNP to create a stack and a role in your AWS account. The stack contains the resources that FortiCNP needs to access and monitor your AWS account. The role allows FortiCNP to assume it and perform actions on your behalf. You need to enter a custom or default role name and a unique UUID that is designated for your company on FortiCNP1.

The next step the administrator must take to access the Linux EC2 instance from the internet is:

D. Allocate an Elastic IP address and assign it to the instance.

Elastic IP (EIP) Requirement: By default, when an EC2 instance is launched in AWS, it receives a public IP address from Amazon's pool, which is not static. This IP address can change, for example, if the instance is stopped and started again. To have a static IP address, you need to allocate an Elastic IP (EIP), which is a persistent public IP address, and then associate it with the instance.

Public Accessibility: Without an Elastic IP, the instance may not be accessible over the internet after a reboot or stop/start sequence. Assigning an Elastic IP ensures the instance can be accessed consistently using the same IP address.

References: The AWS documentation on EC2 instances details the process and need for Elastic IPs to ensure consistent internet access to instances.

To get Terraform ready using Microsoft Azure Cloud Shell, you need to perform the following steps:

Set up a storage account in Azure. This is required to store the Terraform state file in a blob container, which enables collaboration and persistence of the infrastructure configuration1.

Use the wget (terraform_version) command to upload Terraform. This command downloads the latest version of Terraform from the official website and saves it as a zip file in the current directory2.

Move the Terraform file to the bin directory. This step extracts the Terraform executable from the zip file and moves it to the bin directory, which is part of the PATH environment variable. This allows you to run Terraform commands from any directory in Cloud Shell2.

The other options are incorrect because:

You do not need to use the -O command to download Terraform. This command is used to specify a different output file name for the downloaded file, but it is not necessary for this task3.

You do not need to subscribe to Terraform in Azure. Terraform is an open-source tool that can be used with any cloud provider, and there is no subscription or registration required to use it with Azure4. References:

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 the Staging-key.pem file 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.
