Question # 31

A financial trading company is using Amazon EC2 instances to run its trading platform. Part of the company's trading platform includes a third-party pricing service that the EC2 instances communicate with over UDP on port 50000.

Recently, the company has had problems with the pricing service. Some of the responses from the pricing service appear to be incorrectly formatted and are not being processed successfully. The third-party vendor requests access to the data that the pricing service is returning. The third-party vendor wants to capture request and response data for debugging by logging in to an EC2 instance that accesses the pricing service. The company prohibits direct access to production systems and requires all log analysis to be performed in a dedicated monitoring account.

Which set of steps should a network engineer take to capture the data and meet these requirements?

1. Configure VPC flow logs to capture the data that flows in the VPC.

2. Send the data to an Amazon S3 bucket.

3. In the monitoring account, extract the data that flows to the EC2 instance's IP address and filter the traffic for the UDP data.

4. Provide the data to the third-party vendor.

1. Configure a traffic mirror filter to capture the UDP data.

2. Configure Traffic Mirroring to capture the traffic for the EC2 instance's elastic network interface.

3. Configure a packet inspection package on a new EC2 instance in the production environment. Use the elastic network interface of the new EC2 instance as the target for the traffic mirror.

4. Extract the data by using the packet inspection package.

1. Configure a traffic mirror filter to capture the UDP data.

2. Configure Traffic Mirroring to capture the traffic for the EC2 instance's elastic network interface.

3. Configure a packet inspection package on a new EC2 instance in the monitoring account. Use the elastic network interface of the new EC2 instance as the target for the traffic mirror.

4. Extract the data by using the packet inspection package.

1. Create a new Amazon Elastic Block Store (Amazon EBS) volume. Attach the EBS volume to the EC2 instance.

2. Log in to the EC2 instance in the production environment. Run the tcpdump command to capture the UDP data on the EBS volume.

3. Export the data from the EBS volume to Amazon S3.

4. Provide the data to the third-party vendor.

Question # 32

A company's existing AWS environment contains public application servers that run on Amazon EC2 instances. The application servers run in a VPC subnet. Each server is associated with an Elastic IP address.

The company has a new requirement for firewall inspection of all traffic from the internet before the traffic reaches any EC2 instances. A security engineer has deployed and configured a Gateway Load Balancer (GLB) in a standalone VPC with a fleet of third-party firewalls.

How should a network engineer update the environment to ensure that the traffic travels across the fleet of firewalls?

Deploy a transit gateway. Attach a GLB endpoint to the transit gateway. Attach the application VPC to the transit gateway. Update the application subnet route table's default route destination to be the GLB endpoint. Ensure that the EC2 instances' security group allows traffic from the GLB endpoint.

Update the application subnet route table to have a default route to the GLB. On the standalone VPC that contains the firewall fleet, add a route in the route table for the application VPC's CIDR block with the GLB endpoint as the destination. Update the EC2 instances' security group to allow traffic from the GLB.

Provision a GLB endpoint in the application VPC in a new subnet. Create a gateway route table with a route that specifies the application subnet CIDR block as the destination and the GLB endpoint as the target. Associate the gateway route table with the internet gateway in the application VPC. Update the application subnet route table's default route destination to be the GLB endpoint.

Instruct the security engineer to move the GLB into the application VPC. Create a gateway route table. Associate the gateway route table with the application subnet. Add a default route to the gateway route table with the GLB as its destination. Update the route table on the GLB to direct traffic from the internet gateway to the application servers. Ensure that the EC2 instances' security group allows traffic from the GLB.

Question # 33

A company has VPCs in the us-east-1 Region that are connected to each other through a transit gateway. A network engineer needs to establish an AWS Direct Connect connection between the company's on-premises data center and the transit gateway for the migration of a workload.

The Direct Connect connection is UP according to the ConnectionState metric in Amazon CloudWatch. However, the VIF is DOWN. The network engineer has verified the transit VIF and BGP configurations on the on-premises router and has found no issues. However, the network engineer is unable to ping the Amazon peer IP address.

Which combination of steps should the network engineer take to troubleshoot this issue? (Choose three.)

Verify that the correct IP address and subnet mask are in use for the subinterface on the router.

Ensure that VLAN trunking is disabled on the router.

Verify that the router has a MAC address entry from the AWS endpoint in the Address Resolution Protocol (ARP) table.

Verify that the optical signal that is received over the cross connect is optimal.

Ensure that the correct VLAN tag is applied on the subinterface configuration on the router.

Ensure that TCP port 179 is not being blocked at the on-premises router.

Question # 34

For the source of the mirror session, specify the EC2 elastic network interfaces for all the instances that host the application Create a third-party EC2 appliance. Send all traffic to the appliance through the Firehose delivery stream for content inspection.

Configure VPC flow logs on each EC2 network interface. Send the logs to Amazon CloudWatch. Create a third-party EC2 appliance. Configure a CloudWatch filter to send the flow logs to Amazon Data Firehose to load the logs into the appliance.

Question # 35

A company has a hybrid cloud environment. The company’s data center is connected to the AWS Cloud by an AWS Direct Connect connection. The AWS environment includes VPCs that are connected together in a hub-and-spoke model by a transit gateway. The AWS environment has a transit VIF with a Direct Connect gateway for on-premises connectivity.

The company has a hybrid DNS model. The company has configured Amazon Route 53 Resolver endpoints in the hub VPC to allow bidirectional DNS traffic flow. The company is running a backend application in one of the VPCs.

The company uses a message-oriented architecture and employs Amazon Simple Queue Service (Amazon SQS) to receive messages from other applications over a private network. A network engineer wants to use an interface VPC endpoint for Amazon SQS for this architecture. Client services must be able to access the endpoint service from on premises and from multiple VPCs within the company's AWS infrastructure.

Which combination of steps should the network engineer take to ensure that the client applications can resolve DNS for the interface endpoint? (Choose three.)

Create the interface endpoint for Amazon SQS with the option for private DNS names turned on.

Question # 37

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?

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

Enable enhanced networking on the client EC2 instances.

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

Close idle TCP connections through the NAT gateway.

Question # 38

An application team for a startup company is deploying a new multi-tier application into the AWS Cloud. The application will be hosted on a fleet of Amazon EC2 instances that run in an Auto Scaling group behind a publicly accessible Network Load Balancer (NLB). The application requires the clients to work with UDP traffic and TCP traffic.

In the near term, the application will serve only users within the same geographic location. The application team plans to extend the application to a global audience and will move the deployment to multiple AWS Regions around the world to bring the application closer to the end users. The application team wants to use the new Regions to deploy new versions of the application and wants to be able to control the amount of traffic that each Region receives during these rollouts. In addition, the application team must minimize first-byte latency and jitter (randomized delay) for the end users.

How should the application team design the network architecture for the application to meet these requirements?

Create an Amazon CloudFront distribution to align to each Regional deployment. Set the NLB for each Region as the origin for each CloudFront distribution. Use an Amazon Route 53 weighted routing policy to control traffic to the newer Regional deployments.

Create an AWS Global Accelerator accelerator and listeners for the required ports. Configure endpoint groups for each Region. Configure a traffic dial for the endpoint groups to control traffic to the newer Regional deployments. Register the NLBs with the endpoint groups.

Use Amazon S3 Transfer Acceleration for the application in each Region. Adjust the amount of traffic that each Region receives from the Transfer Acceleration endpoints to the Regional NLBs.

Create an Amazon CloudFront distribution that includes an origin group. Set the NLB for each Region as the origins for the origin group. Use an Amazon Route 53 latency routing policy to control traffic to the new Regional deployments.

Question # 39

A company's AWS architecture consists of several VPCs. The VPCs include a shared services VPC and several application VPCs. The company has established network connectivity from all VPCs to the on-premises DNS servers.

Applications that are deployed in the application VPCs must be able to resolve DNS for internally hosted domains on premises. The applications also must be able to resolve local VPC domain names and domains that are hosted in Amazon Route 53 private hosted zones.

What should a network engineer do to meet these requirements?

Create a new Route 53 Resolver inbound endpoint in the shared services VPC. Create forwarding rules for the on-premises hosted domains. Associate the rules with the new Resolver endpoint and each application VPC. Update each application VPC's DHCP configuration to point DNS resolution to the new Resolver endpoint.
