Amazon AWS Certified Advanced Networking - Specialty Questions and Answers

Question 37

A company's application is deployed on Amazon EC2 instances in a single VPC in an AWS Region. The EC2 instances are running in two Availability Zones. The company decides to use a fleet of traffic inspection instances from AWS Marketplace to inspect traffic between the VPC and the internet. The company is performing tests before the company deploys the architecture into production.

The fleet is located in a shared inspection VPC behind a Gateway Load Balancer (GWLB). To minimize the cost of the solution, the company deployed only one inspection instance in each Availability Zone that the application uses.

During tests, a network engineer notices that traffic inspection works as expected when the network is stable. However, during maintenance of the inspection instances, the internet sessions time out for some application instances. The application instances are not able to establish new sessions.

Which combination of steps will remediate these issues? (Choose two.)

Options:

A.

Deploy one inspection instance in the Availability Zones that do not have inspection instances deployed.

B.

Deploy one additional inspection instance in each Availability Zone where the inspection instances are deployed.

C.

Enable the cross-zone load balancing attribute for the GWLB.

D.

Deploy inspection instances in an Auto Scaling group. Define a scaling policy that is based on CPU load.

E.

Attach the GWLB to all Availability Zones in the Region.

Question 38

A company is growing rapidly. Data transfers between the company's on-premises systems and Amazon EC2 instances that run in VPCs are limited by the throughput of a single AWS Site-to-Site VPN connection between the company's on-premises data center firewall and an AWS Transit Gateway.

A network engineer must resolve the throttling by designing a solution that is highly available and secure. The solution also must scale the VPN throughput from on premises to the VPC resources to support the increase in traffic.

Which solution will meet these requirements?

Options:

A.

Configure multiple dynamic BGP-based Site-to-Site VPN connections to the transit gateway Configure equal-cost multi-path routing

B.

Configure multiple static routing-based Site-to-Site VPN connections to the transit gateway. Configure equal-cost multi-path routing

C.

Configure a new Site-to-Site VPN connection to the transit gateway Enable acceleration for the Site-to-Site VPN connection.

D.

Configure a software appliance-based VPN connection over the internet from the on-premises firewall to an EC2 instance that has a large instance size and networking capabilities.

Question 39

An Australian ecommerce company hosts all of its services in the AWS Cloud and wants to expand its customer base to the United States (US). The company is targeting the western US for the expansion.

The company’s existing AWS architecture consists of four AWS accounts with multiple VPCs deployed in the ap-southeast-2 Region. All VPCs are attached to a transit gateway in ap-southeast-2. There are dedicated VPCs for each application service. The company also has VPCs for centralized security features such as proxies, firewalls, and logging.

The company plans to duplicate the infrastructure from ap-southeast-2 to the us-west-1 Region. A network engineer must establish connectivity between the various applications in the two Regions. The solution must maximize bandwidth, minimize latency and minimize operational overhead.

Which solution will meet these requirements?

Options:

A.

Create VPN attachments between the two transit gateways. Configure the VPN attachments to use BGP routing between the two transit gateways.

B.

Peer the transit gateways in each Region. Configure routing between the two transit gateways for each Region's IP addresses.

C.

Create a VPN server in a VPC in each Region. Update the routing to point to the VPN servers for the IP addresses in alternate Regions.

D.

Attach the VPCs in us-west-1 to the transit gateway in ap-southeast-2.

Question 40

A company is deploying third-party firewall appliances for traffic inspection and NAT capabilities in its VPC. The VPC is configured with private subnets and public subnets. The company needs to deploy the firewall appliances behind a load balancer.

Which architecture will meet these requirements MOST cost-effectively?

Options:

A.

Deploy a Gateway Load Balancer with the firewall appliances as targets. Configure the firewall appliances with a single network interface in a private subnet. Use a NAT gateway to send the traffic to the internet after inspection.

B.

Deploy a Gateway Load Balancer with the firewall appliances as targets. Configure the firewall appliances with two network interfaces: one network interface in a private subnet and another network interface in a public subnet. Use the NAT functionality on the firewall appliances to send the traffic to the internet after inspection.

C.

Deploy a Network Load Balancer with the firewall appliances as targets. Configure the firewall appliances with a single network interface in a private subnet. Use a NAT gateway to send the traffic to the internet after inspection.

D.

Deploy a Network Load Balancer with the firewall appliances as targets. Configure the firewall appliances with two network interfaces: one network interface in a private subnet and another network interface in a public subnet. Use the NAT functionality on the firewall appliances to send the traffic to the internet after inspection.
