Question 17

A real estate company is building an internal application so that real estate agents can upload photos and videos of various properties. The application will store these photos and videos in an Amazon S3 bucket as objects and will use Amazon DynamoDB to store corresponding metadata. The S3 bucket will be configured to publish all PUT events for new object uploads to an Amazon Simple Queue Service (Amazon SQS) queue.

A compute cluster of Amazon EC2 instances will poll the SQS queue to find out about newly uploaded objects. The cluster will retrieve new objects, perform proprietary image and video recognition and classification update metadata in DynamoDB and replace the objects with new watermarked objects. The company does not want public IP addresses on the EC2 instances.

Which networking design solution will meet these requirements MOST cost-effectively as application usage increases?

Options:

Place the EC2 instances in a public subnet. Disable the Auto-assign Public IP option while launching the EC2 instances. Create an internet gateway. Attach the internet gateway to the VPC. In the public subnet's route table, add a default route that points to the internet gateway.

Place the EC2 instances in a private subnet. Create a NAT gateway in a public subnet in the same Availability Zone. Create an internet gateway. Attach the internet gateway to the VPC. In the public subnet's route table, add a default route that points to the internet gateway

Place the EC2 instances in a private subnet. Create an interface VPC endpoint for Amazon SQS.Create gateway VPC endpoints for Amazon S3 and DynamoDB.

Question 18

A company has a hybrid environment that connects an on-premises data center to the AWS Cloud. The hybrid environment uses a 10 Gbps AWS Direct Connect dedicated connection. The Direct Connect connection has multiple private VIFs that terminate in multiple VPCs.

To comply with regulations, the company must encrypt all WAN traffic, regardless of the underlying transport. The company needs to implement an encryption solution that will not affect the company's bandwidth capacity.

Which solution will meet these requirements?

Options:

Create a public VIF. Configure a new AWS Site-to-Site VPN connection to use the new public VIF.

Configure MAC security (MACsec) support on the port of the existing Direct Connect connection. Change the encryption mode to must_encrypt.

Configure a new Direct Connect connection that supports MAC security (MACSec) Associate the existing VIFs to the new Direct Connect connection.

Create a public VIF. Configure a new private IP VPN that uses the Direct Connect connection.

Question 19

A Network Engineer is provisioning a subnet for a load balancer that will sit in front of a fleet of application servers in a private subnet. There is limited IP space left in the VPC CIDR. The application has few users now but is expected to grow quickly to millions of users.

What design will use the LEAST amount of IP space, while allowing for this growth?

Options:

Use two /29 subnets for an Application Load Balancer in different Availability Zones.

Use one /29 subnet for the Network Load Balancer. Add another VPC CIDR to the VPC to allow for future growth.

Use two /28 subnets for a Network Load Balancer in different Availability Zones.

Use one /28 subnet for an Application Load Balancer. Add another VPC CIDR to the VPC to allow for future growth.

Question 20

A company wants to improve visibility into its AWS environment. The AWS environment consists of multiple VPCs that are connected to a transit gateway. The transit gateway connects to an on-premises data center through an AWS Direct Connect gateway and a pair of redundant Direct Connect connections that use transit VIFs. The company must receive notification each time a new route is advertised to AWS from on premises over Direct Connect.

What should a network engineer do to meet these requirements?

Options:

Enable Amazon CloudWatch metrics on Direct Connect to track the received routes. Configure a CloudWatch alarm to send notifications when routes change.

Onboard Transit Gateway Network Manager to Amazon CloudWatch Logs Insights. Use Amazon EventBridge (Amazon CloudWatch Events) to send notifications when routes change.

Configure an AWS Lambda function to periodically check the routes on the Direct Connect gateway and to send notifications when routes change.

Enable Amazon CloudWatch Logs on the transit VIFs to track the received routes. Create a metric filter Set an alarm on the filter to send notifications when routes change.
