Question 20

A company has developed APIs that use Amazon API Gateway with Regional endpoints. The APIs call AWS Lambda functions that use API Gateway authentication mechanisms. After a design review, a solutions architect identifies a set of APIs that do not require public access.

The solutions architect must design a solution to make the set of APIs accessible only from a VPC. All APIs need to be called with an authenticated user.

Which solution will meet these requirements with the LEAST amount of effort?

Options:

Create an internal Application Load Balancer (ALB). Create a target group. Select the Lambda function to call. Use the ALB DNS name to call the API from the VPC.

Remove the DNS entry that is associated with the API in API Gateway. Create a hosted zone in Amazon Route 53. Create a CNAME record in the hosted zone. Update the API in API Gateway with the CNAME record. Use the CNAME record to call the API from the VPC.

Update the API endpoint from Regional to private in API Gateway. Create an interface VPC endpoint in the VPC. Create a resource policy, and attach it to the API. Use the VPC endpoint to call the API from the VPC.

Deploy the Lambda functions inside the VPC. Provision an EC2 instance, and install an Apache server. From the Apache server, call the Lambda functions. Use the internal CNAME record of the EC2 instance to call the API from the VPC.

Question 21

A company is building an application on AWS. The application sends logs to an Amazon OpenSearch Service cluster for analysis. All data must be stored within a VPC.

Some of the company ' s developers work from home. Other developers work from three different company office locations. The developers need to access OpenSearch Service to analyze and visualize logs directly from their local development machines.

Which solution will meet these requirements?

Options:

Configure and set up an AWS Client VPN endpoint. Associate the Client VPN endpoint with a subnet in the VPC. Configure a Client VPN self-service portal. Instruct the developers to connect by using the client for Client VPN.

Create a transit gateway, and connect it to the VPC. Create an AWS Site-to-Site VPN. Create an attachment to the transit gateway. Instruct the developers to connect by using an OpenVPN client.

Create a transit gateway, and connect it to the VPC. Order an AWS Direct Connect connection. Set up a public VIF on the Direct Connect connection. Associate the public VIF with the transit gateway. Instruct the developers to connect to the Direct Connect connection.

Create and configure a bastion host in a public subnet of the VPC. Configure the bastion host security group to allow SSH access from the company CIDR ranges. Instruct the developers to connect by using SSH.

Answer:

Explanation:

The key requirements are: OpenSearch Service must be deployed within a VPC (VPC-only access), and developers must access OpenSearch from their local machines across multiple locations, including home networks. The most suitable low-overhead approach is to provide remote users with secure client-based connectivity into the VPC so they can reach private endpoints.

AWS Client VPN is a managed client-based VPN service that allows individual users to establish secure TLS VPN connections from their devices into a VPC. By associating a Client VPN endpoint with a subnet in the VPC and configuring authorization rules and routes, developers can access private resources (including VPC-only Amazon OpenSearch Service endpoints) as if they were on the corporate network. Client VPN is designed for distributed workforces and supports users connecting from anywhere without requiring each remote location to have dedicated network appliances.

Option A matches the need for remote developer access from home and multiple offices with the least operational overhead because it is a managed service for user-based VPN access and does not require running and maintaining bastion fleets or building site-to-site networks for each location.

Option B is not correct because AWS Site-to-Site VPN is designed to connect networks (for example, an office network or data center) to AWS, not to provide individual developers remote access from arbitrary home networks. Also, instructing developers to use an OpenVPN client does not align with how Site-to-Site VPN is typically used; Site-to-Site VPN terminates on a customer gateway device, not on individual laptops.

Option C is not correct because Direct Connect is designed for dedicated private connectivity between on-premises networks and AWS. It is not a solution for individual developers connecting from home. Additionally, using a public VIF is for reaching public AWS endpoints, whereas the requirement is to keep access within a VPC. A public VIF does not provide private VPC access to VPC-only service endpoints.

Option D is not the best choice because a bastion host provides SSH access to instances, not direct, secure network-level access to VPC-only managed service endpoints from developer tools. It also increases operational overhead (patching, hardening, monitoring, scaling) and introduces additional security considerations. Developers also typically need browser-based or tool-based access to OpenSearch Dashboards, which is better served by VPN access into the VPC than SSH tunneling through a bastion host as a primary access mechanism.

Therefore, configuring AWS Client VPN to provide developers with secure connectivity into the VPC is the correct solution.

Question 22

A company runs many workloads on AWS and uses AWS Organizations to manage its accounts. The workloads are hosted on Amazon EC2. AWS Fargate. and AWS Lambda. Some of the workloads have unpredictable demand. Accounts record high usage in some months and low usage in other months.

The company wants to optimize its compute costs over the next 3 years A solutions architect obtains a 6-month average for each of the accounts across the organization to calculate usage.

Which solution will provide the MOST cost savings for all the organization ' s compute usage?

Options:

Purchase Reserved Instances for the organization to match the size and number of the most common EC2 instances from the member accounts.

Purchase a Compute Savings Plan for the organization from the management account by using the recommendation at the management account level

Purchase Reserved Instances for each member account that had high EC2 usage according to the data from the last 6 months.

Purchase an EC2 Instance Savings Plan for each member account from the management account based on EC2 usage data from the last 6 months.

Question 23

A large mobile gaming company has successfully migrated all of its on-premises infrastructure tothe AWS Cloud. A solutions architect is reviewing the environment to ensure that it was built according to the design and that it is running in alignment with the Well-Architected Framework.

While reviewing previous monthly costs in Cost Explorer, the solutions architect notices that the creation and subsequent termination of several large instance types account for a high proportion of the costs. The solutions architect finds out that the company ' s developers are launching new Amazon EC2 instances as part of their testing and that the developers are not using the appropriate instance types.

The solutions architect must implement a control mechanism to limit the instance types that only the developers can launch.

Which solution will meet these requirements?

Options:

Create a desired-instance-type managed rule in AWS Config. Configure the rule with the instance types that are allowed. Attach the rule to an event to run each time a new EC2 instance is launched.

In the EC2 console, create a launch template that specifies the instance types that are allowed. Assign the launch template to the developers ' IAM accounts.

Create a new IAM policy. Specify the instance types that are allowed. Attach the policy to an IAM group that contains the IAM accounts for the developers

Use EC2 Image Builder to create an image pipeline for the developers and assist them in the creation of a golden image.
