Question # 8

A solutions architect is importing a VM from an on-premises environment by using the Amazon EC2 VM Import feature of AWS Import/Export. The solutions architect has created an AMI and has provisioned an Amazon EC2 instance that is based on that AMI. The EC2 instance runs inside a public subnet in a VPC and has a public IP address assigned.

The EC2 instance does not appear as a managed instance in the AWS Systems Manager console.

Which combination of steps should the solutions architect take to troubleshoot this issue? (Select TWO.)

Options:

Verify that Systems Manager Agent is installed on the instance and is running.

Verify that the instance is assigned an appropriate IAM role for Systems Manager.

Verify the existence of a VPC endpoint on the VP

Verify that the AWS Application Discovery Agent is configured.

Verify the correct configuration of service-linked roles for Systems Manager.

Discussion 0

Answer:

A, B

Explanation:

For an EC2 instance to appear as a managed instance in AWS Systems Manager, several prerequisites must be met. Two of the most fundamental requirements are that the Systems Manager Agent (SSM Agent) is installed and running on the instance, and that the instance has an IAM role attached that grants the necessary permissions for Systems Manager to communicate with the service.

When importing a VM from an on-premises environment, the resulting AMI might not include the SSM Agent by default, or the agent might not be enabled to start automatically. If the agent is missing or not running, the instance cannot register with Systems Manager, and it will not appear in the Systems Manager console as a managed instance. Therefore, verifying that the SSM Agent is installed and running is a primary troubleshooting step.

Additionally, the EC2 instance must have an IAM instance profile (role) attached that includes the permissions required by Systems Manager. Typically, this is achieved by attaching a role that includes the AmazonSSMManagedInstanceCore managed policy. Without the appropriate IAM role, even a correctly installed and running agent will not be able to register the instance or perform Systems Manager operations.

Option C (VPC endpoint existence) is not required in this scenario because the instance is in a public subnet and has a public IP address. In this case, the instance can communicate with the Systems Manager endpoints over the internet. VPC endpoints are required when instances do not have internet access (for example, in private subnets without NAT or public IPs), which is not the case here.

Option D (Application Discovery Agent) is unrelated. The AWS Application Discovery Agent is used for migration assessment and discovery of on-premises workloads, not for Systems Manager managed instance registration.

Option E (service-linked roles) is generally not a common cause for a single instance failing to appear as managed, especially when other Systems Manager functionality is working in the account. Service-linked roles for Systems Manager are usually created automatically when needed and do not typically prevent an individual instance from registering if the agent and instance role are correctly configured.

Therefore, the correct troubleshooting steps are to verify the presence and operation of the Systems Manager Agent and to ensure the EC2 instance has the correct IAM role attached.

[References:AWS documentation on prerequisites for AWS Systems Manager managed instances, including the requirement for the SSM Agent to be installed and running.AWS documentation on IAM instance profiles and required permissions (such as AmazonSSMManagedInstanceCore) for EC2 instances to be managed by Systems Manager., , ]

Question # 9

A company is running an application in the AWS Cloud. The company's security team must approve the creation of all new IAM users. When a new IAM user is created, all access for the user must be removed automatically. The security team must then receive a notification to approve the user. The company has a multi-Region AWS CloudTrail trail In the AWS account.

Which combination of steps will meet these requirements? (Select THRE

)

Options:

Create an Amazon EventBridge (Amazon CloudWatch Events) rule. Define a pattern with the detail-type value set to AWS API Call via CloudTrail and an eventName of CreateUser.

Configure CloudTrail to send a notification for the CreateUser event to an Amazon Simple Notification Service (Amazon SNS) topic.

Invoke a container that runs in Amazon Elastic Container Service (Amazon ECS) with AWS Fargate technology to remove access

Invoke an AWS Step Functions state machine to remove access.

Use Amazon Simple Notification Service (Amazon SNS) to notify the security team.

Use Amazon Pinpoint to notify the security team.

Question # 11

A Solutions Architect wants to make sure that only AWS users or roles with suitable permissions can access a new Amazon API Gateway endpoint. The Solutions

Architect wants an end-to-end view of each request to analyze the latency of the request and create service maps.

How can the Solutions Architect design the API Gateway access control and perform request inspections?

Options:

For the API Gateway method, set the authorization to AWS_IAM. Then, give the IAM user or role execute-api:Invoke permission on the REST API resource. Enable the API caller to sign requests with AWS Signature when accessing the endpoint. Use AWS X-Ray to trace and analyze user requests to API Gateway.

For the API Gateway resource, set CORS to enabled and only return the company's domain in Access-Control-Allow-Origin headers. Then, give the IAM user or role execute-api:Invoke permission on the REST API resource. Use Amazon CloudWatch to trace and analyze user requests to API Gateway.

Create an AWS Lambda function as the custom authorizer, ask the API client to pass the key and secret when making the call, and then use Lambda to validate the key/secret pair against the IAM system. Use AWS X-Ray to trace and analyze user requests to API Gateway.

Create a client certificate for API Gateway. Distribute the certificate to the AWS users and roles that need to access the endpoint. Enable the API caller to pass the client certificate when accessing the endpoint. Use Amazon CloudWatch to trace and analyze user requests to API Gateway.

Question # 12

A solutions architect wants to cost-optimize and appropriately size Amazon EC2 instances in a single AWS account. The solutions architect wants to ensure that the instances are optimized based on CPU, memory, and network metrics.

Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)

Options:

Purchase AWS Business Support or AWS Enterprise Support for the account.

Turn on AWS Trusted Advisor and review any “Low Utilization Amazon EC2 Instances” recommendations.

Install the Amazon CloudWatch agent and configure memory metric collection on the EC2 instances.

Configure AWS Compute Optimizer in the AWS account to receive findings and optimization recommendations.

Create an EC2 Instance Savings Plan for the AWS Regions, instance families, and operating systems of interest.

Discussion 0

Answer:

B, D

Explanation:

AWS Trusted Advisor is a service that provides real-time guidance to help users provision their resources following AWS best practices1. One of the Trusted Advisor checks is “Low Utilization Amazon EC2 Instances”, which identifies EC2 instances that appear to be underutilized based on CPU, network I/O, and disk I/O metrics1. This check can help users optimize the cost and size of their EC2 instances by recommending smaller or more appropriate instance types.

AWS Compute Optimizer is a service that analyzes the configuration and utilization metrics of AWS resources and generates optimization recommendations to reduce the costand improve the performance of workloads2. Compute Optimizer supports four types of AWS resources: EC2 instances, EBS volumes, ECS services on AWSFargate, and Lambdafunctions2. For EC2 instances, Compute Optimizer evaluates the vCPUs, memory, storage, and other specifications, as well as the CPU utilization, network in and out, disk read and write, and other utilization metrics of currently running instances3. It then recommends optimal instance types based on price-performance trade-offs.

Option A is incorrect because purchasing AWS Business Support or AWS Enterprise Support for the account will not directly help with cost-optimization and sizing of EC2 instances. However, these support plans do provide access to more Trusted Advisor checks than the basic support plan1.

Option C is incorrect because installing the Amazon CloudWatch agent and configuring memory metric collection on the EC2 instances will not provide any optimization recommendations by itself. However, memory metrics can be used by Compute Optimizer to enhance its recommendations if enabled3.

Option E is incorrect because creating an EC2 Instance Savings Plan for the AWS Regions, instance families, and operating systems of interest will not help with cost-optimization and sizing of EC2 instances. Savings Plans are a flexible pricing model that offer lower prices on Amazon EC2 usage in exchange for a commitment to a consistent amount of usage for a 1- or 3-year term4. Savings Plans do not affect the configuration or utilization of EC2 instances.

Question # 13

A company stores application data in many Amazon S3 buckets in one AWS account. Some of the S3 buckets contain sensitive data. The company does not have data inventory for the S3 buckets. The company uses server-side encryption with Amazon S3 managed keys (SSE-S3) to encrypt all data in the S3 buckets.

A solutions architect must design a solution to encrypt sensitive data with a key that only administrators can access.

Which solution will meet these requirements?

Options:

Use Amazon Inspector to determine which S3 buckets contain sensitive data. Create a new AWS KMS customer managed key and a key policy that provides access to administrators only. Set default S3 bucket encryption to use the new KMS key (SSE-KMS). Update the S3 bucket policy to add a Deny effect and a Condition element of "StringNotEquals": { "s3:x-amz-server-side-encryption": "aws:kms" }.

Question # 15

A company operates a static content distribution platform that serves customers globally. The customers consume content from their own AWS accounts.

The company serves its content from an Amazon S3 bucket. The company uploads the content from its on-premises environment to the S3 bucket by using an S3 File Gateway.

The company wants to improve the platform's performance and reliability by serving content from the AWS Region that is geographically closest to customers. The company must route the on-premises data to Amazon S3 with minimal latency and without public internet exposure.

Which combination of steps will meet these requirements with the LEAST operational overhead? (Select TWO.)

Options:

Implement S3 Multi-Region Access Points.

Use S3 Cross-Region Replication (CRR) to copy content to different Regions.

Create an AWS Lambda function that tracks the routing of clients to Regions.

Use an AWS Site-to-Site VPN connection to connect to a Multi-Region Access Point.

Use AWS PrivateLink and AWS Direct Connect to connect to a Multi-Region Access Point.

Discussion 0

Answer:

A, E

Explanation:

This explanation is based on AWS documentation and best practices but is paraphrased, not a literal extract.

The company needs two things:

To serve static content from the AWS Region geographically closest to each customer.

To send data from on premises to Amazon S3 with minimal latency and without traversing the public internet, while keeping operational overhead low.

S3 Multi-Region Access Points provide a single global endpoint that fronts multiple S3 buckets in different Regions. Multi-Region Access Points use latency-based routing and failover capabilities to direct client requests automatically to the closest healthy Regional S3 bucket that is part of the Multi-Region Access Point. This directly addresses the requirement to serve content from the closest Region with high performance and reliability, and it avoids the need to build and maintain custom routing logic.

Behind the scenes, S3 Multi-Region Access Points rely on S3 Replication between the Regional buckets that participate in the Multi-Region Access Point. When you configure a Multi-Region Access Point, you set up the participating buckets and replication configuration once; AWS then manages routing and failover, reducing operational overhead compared to manually configuring and managing multiple S3 endpoints and application logic.

For the on-premises environment, the company wants to send data to S3 with minimal latency and without using the public internet. AWS Direct Connect provides a dedicated network connection from the on-premises network into AWS, avoiding the public internet and generally providing lower and more consistent latency. AWS PrivateLink allows private connectivity to supported AWS services (such as S3 Multi-Region Access Points via interface endpoints) from within a VPC using private IP addresses. When you combine Direct Connect with PrivateLink, traffic flows from on-premises over a private dedicated connection into a VPC and then privately to the Multi-Region Access Point through an interface VPC endpoint, satisfying the requirement for no public internet exposure.

Therefore, implementing S3 Multi-Region Access Points (option A) addresses the global content serving and Regional routing, and using AWS PrivateLink together with AWS Direct Connect (option E) provides low-latency, private network connectivity from on premises to the Multi-Region Access Point with minimal operational overhead.

Option B, S3 Cross-Region Replication alone, would replicate data across Regions but would not automatically route customers to the closest Region; application changes and manual routing would be required, increasing operational overhead.

Option C would require building and maintaining a custom Lambda-based routing system, which is unnecessary when S3 Multi-Region Access Points provide managed routing and failover.

Option D, AWS Site-to-Site VPN, encrypts traffic over the public internet; it does not satisfy the explicit requirement to avoid public internet exposure and typically has less predictable latency than Direct Connect.

[References:AWS documentation on Amazon S3 Multi-Region Access Points, including latency-based routing and built-in replication between Regional buckets.AWS Direct Connect documentation describing private, dedicated connectivity from on-premises to AWS to reduce latency and avoid public internet exposure.AWS PrivateLink documentation describing access to supported services over private IP addresses via interface VPC endpoints.]
