Amazon AWS Certified Advanced Networking - Specialty Questions and Answers

Question 65

A company is using an Amazon CloudFront distribution that is configured with an Application Load Balancer (ALB) as an origin. A network engineer needs to implement a solution that requires

all inbound traffic to the ALB to come from CloudFront. The network engineer must implement the solution at the network layer rather than in the application.

Which solution will meet these requirements in the MOST operationally efficient way?

Options:

A.

Add an inbound rule to the ALB's security group to allow the AWS managed prefix list for CloudFront.

B.

Add an inbound rule to the network ACLs that are associated with the ALB's subnets. Use the AWS managed prefix list for CloudFront as the source in the rule.

C.

Configure CloudFront to add a custom HTTP header to the requests that CloudFront sends to the ALB.

D.

Associate an AWS WAF web ACL with the ALB. Configure the AWS WAF rules to allow traffic from the CloudFront IP set. Automatically update the CloudFront IP set by using an AWS Lambda function.

Question 66

A network engineer must provide additional safeguards to protect encrypted data at ApplicationLoad Balancers (ALBs) through the use of a unique random session key.

What should the network engineer do to meet this requirement?

Options:

A.

Change the ALB security policy to a policy that supports TLS 1.2 protocol only

B.

Use AWS Key Management Service (AWS KMS) to encrypt session keys

C.

Associate an AWS WAF web ACL with the ALBs. and create a security rule to enforce forward secrecy (FS)

D.

Change the ALB security policy to a policy that supports forward secrecy (FS)

Question 67

A retail company is running its service on AWS. The company’s architecture includes Application Load Balancers (ALBs) in public subnets. The ALB target groups are configured to send traffic tobackend Amazon EC2 instances in private subnets. These backend EC2 instances can call externally hosted services over the internet by using a NAT gateway.

The company has noticed in its billing that NAT gateway usage has increased significantly. A network engineer needs to find out the source of this increased usage.

Which options can the network engineer use to investigate the traffic through the NAT gateway? (Choose two.)

Options:

A.

Enable VPC flow logs on the NAT gateway's elastic network interface. Publish the logs to a log group in Amazon CloudWatch Logs. Use CloudWatch Logs Insights to query and analyze the logs.

B.

Enable NAT gateway access logs. Publish the logs to a log group in Amazon CloudWatch Logs. Use CloudWatch Logs Insights to query and analyze the logs.

C.

Configure Traffic Mirroring on the NAT gateway's elastic network interface. Send the traffic to an additional EC2 instance. Use tools such as tcpdump and Wireshark to query and analyze the mirrored traffic.

D.

Enable VPC flow logs on the NAT gateway's elastic network interface. Publish the logs to an Amazon S3 bucket. Create a custom table for the S3 bucket in Amazon Athena to describe the log structure. Use Athena to query and analyze the logs.

E.

Enable NAT gateway access logs. Publish the logs to an Amazon S3 bucket. Create a custom table for the S3 bucket in Amazon Athena to describe the log structure. Use Athena to query and analyze the logs.

Question 68

A global company is establishing network connections between the company's primary and secondary data centers and a VPC. A network engineer needs to maximize resiliency and fault tolerance for the connections. The network bandwidth must be greater than 10 Gbps.

Which solution will meet these requirements MOST cost-effectively?

Options:

A.

Set up a 100 Gbps connection at the primary data center that terminates at an AWS Direct Connect location. Set up a second 100 Gbps connection at the secondary data center that terminates at a second Direct Connect location. Ensure the connections aremanaged by separate providers.

B.

Set up a 10 Gbps connection at the primary data center that terminates at an AWS Direct Connect location. Set up a second 10 Gbps connection at the secondary data center that terminates at a second Direct Connect location. Ensure the connections are managed by separate providers.

C.

Set up two 10 Gbps connections at the primary data center that terminate at one AWS Direct Connect location. Ensure the connections are managed by separate providers. Set up two 10 Gbps connections at the secondary data center that terminate at a second Direct Connect location. Ensure the connections are managed by separate providers.

D.

Set up a 10 Gbps connection at the primary data center that terminates at an AWS Direct Connect location. Set up an AWS Site-to-Site VPN connection at the secondary data center that terminates at a virtual private gateway in the same Region as the company’s VPC.
