Explanation
A: The peer GRE address is the FortiGate external interface IP address. This is the IP address of the FortiGate interface that is connected to the transit gateway attachment subnet1. This IP address is used to establish the GRE tunnel between the FortiGate and the transit gateway2. B. The Transit Gateway GRE address is auto-generated. This is the IP address of the transit gateway that is used to establish the GRE tunnel with the FortiGate2. This IP address is automatically assigned by AWS from the Transit Gateway CIDR range that you specify when you create the Connect attachment3.
The other options are incorrect because:
The BGP inside CIDR blocks cannot be any CIDR block with /29. They must be a /29 CIDR block from the 169.254.0.0/16 range for IPv4, or a /125 CIDR block from the fd00::/8 range for IPv64. These are the inside IP addresses that are used for BGP peering over the GRE tunnel4.
The Peer GRE address is not the FortiGate internal interface IP address. The internal interface IP address is used to route traffic from the FortiGate to the VPC subnet where the third-party appliance (such as SD-WAN) is located1. The Peer GRE address is used to route traffic from the FortiGate to the transit gateway over the GRE tunnel2.

Explanation
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.

Explanation
The exhibit shows the results of a FortiCNP registry scan, which is part of the FortiCNP container protection. FortiCNP's Container Protection provides deep visibility into the security posture of container registries and images1. The registry scan utilizes Common Vulnerabilities and Exposures (CVE) index regularly updated by NVD to detect underlying vulnerabilities, security flaws, and provides security best practices2. The registry scan is performed at the registry level, and it can scan all images in a repository if the Tag section is left blank when adding a repository2. The CAP section stands for Container Assurance Policy, which defines the minimum number of images to be scanned per repository3. Therefore, the correct statements are A and C.

Explanation
A: Use the terraform destroy command. This command is used to remove all the resources that were created using the Terraform configuration1. It is the opposite of the terraform apply command, which is used to create resources. The terraform destroy command will first show a plan of what resources will be destroyed, and then ask for confirmation before proceeding. The command will also update the state file to reflect the changes. D.
The administrator must manually delete the Linux server. This is because the Linux server was not deployed using Terraform, but using AWS Marketplace2. Therefore, Terraform does not have any information about the Linux server in its state file, and cannot manage or destroy it. The administrator will have to use the AWS console or CLI to delete the Linux server manually.
The other options are incorrect because:
There is no terraform validate command. The correct command is terraform plan, which is used to show a plan of what changes will be made by applying the configuration3. However, this command does not delete any resources, it only shows what will happen if terraform apply or terraform destroy is run.
There is no terraform destroy all command. The correct command is terraform destroy, which will destroy all the resources in the current configuration by default1. There is no need to add an all argument to the command.
