Amazon AWS Certified Advanced Networking - Specialty Questions and Answers

Question 1

A company recently migrated its Amazon EC2 instances to VPC private subnets to satisfy a security compliance requirement. The EC2 instances now use a NAT gateway for internet access. After the migration, some long-running database queries from private EC2 instances to a publicly accessible third-party database no longer receive responses. The database query logs reveal that the queries successfully completed after 7 minutes but that the client EC2 instances never received the response.

Which configuration change should a network engineer implement to resolve this issue?

Options:

A.

Configure the NAT gateway timeout to allow connections for up to 600 seconds.

B.

Enable enhanced networking on the client EC2 instances.

C.

Enable TCP keepalive on the client EC2 instances with a value of less than 300 seconds.

D.

Close idle TCP connections through the NAT gateway.

Question 2

A network engineer must develop an AWS CloudFormation template that can create a virtual private gateway, a customer gateway, a VPN connection, and static routes in a route table. During testing of the template, the network engineer notes that the CloudFormation template has encountered an error and is rolling back.

What should the network engineer do to resolve the error?

Options:

A.

Change the order of resource creation in the CloudFormation template.

B.

Add the DependsOn attribute to the resource declaration for the virtual private gateway. Specify the route table entry resource.

C.

Add a wait condition in the template to wait for the creation of the virtual private gateway.

D.

Add the DependsOn attribute to the resource declaration for the route table entry. Specify the virtual private gateway resource.

Question 3

A network engineer needs to design the architecture for a high performance computing (HPC) workload. Amazon EC2 instances will require 10 Gbps flows and an aggregate throughput of up to 100 Gbps across many instances with low-latency communication.

Which architecture solution will optimize this workload?

Options:

A.

Place nodes in a single subnet of a VPC. Configure a cluster placement group. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.

B.

Place nodes in multiple subnets in a single VPC. Configure a spread placement group Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.

C.

Place nodes in multiple VPCs. Use AWS Transit Gateway to route traffic between the VPCs. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.

D.

Place nodes in multiple subnets in multiple Availability Zones. Configure a cluster placement group. Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.
