NEW QUESTION # 36
A company has a new security policy that requires all Amazon Elastic Block Store (Amazon EBS) volumes to be encrypted at rest. The company needs to use a custom key policy to manage access to the encryption keys.
The company must rotate the keys once each year.
Which solution will meet these requirements with the LEAST operational overhead?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract of AWS CloudOps Documents:
The correct answer is A because AWS KMS symmetric customer managed keys with automatic key rotation provide encryption, access control, and compliance with minimal operational effort. AWS CloudOps documentation states that Amazon EBS encryption supports AWS KMS symmetric keys only, and customer managed keys allow administrators to define custom key policies to control access.
Automatic key rotation is supported for symmetric customer managed keys and rotates the backing key material once every year, fully satisfying the company's rotation requirement without manual intervention.
This approach minimizes operational overhead while maintaining strong security controls and auditability.
Option B is incorrect because AWS owned keys do not allow custom key policies and therefore cannot meet the access control requirement. Option C is incorrect because asymmetric KMS keys are not supported for EBS encryption. Option D is incorrect because imported key material requires manual rotation and re-import, increasing operational complexity and risk.
AWS CloudOps security best practices strongly recommend customer managed symmetric keys with automatic rotation when organizations need fine-grained access control, regulatory compliance, and low maintenance overhead.

NEW QUESTION # 37
A company that uses AWS Organizations recently implemented AWS Control Tower. The company now needs to centralize identity management. A CloudOps engineer must federate AWS IAM Identity Center with an external SAML 2.0 identity provider (IdP) to centrally manage access to all AWS accounts and cloud applications.
Which prerequisites must the CloudOps engineer have so that the CloudOps engineer can connect to the external IdP? (Select TWO.)
Answer: C,E
Explanation:
According to the AWS Cloud Operations and Identity Management documentation, when configuring federation between IAM Identity Center (formerly AWS SSO) and an external SAML
2.0 identity provider, two key prerequisites are required:
The IAM Identity Center SAML metadata file -- This is uploaded to the external IdP to establish trust, define SAML endpoints, and enable identity federation.
The IdP metadata (including the public X.509 certificate) -- This information is imported into IAM Identity Center to validate authentication assertions and encryption signatures.
IAM Identity Center and the IdP exchange this metadata to mutually establish secure, bidirectional federation.
Network-level details such as IP addresses (Option C) are unnecessary. Root access (Option D) or permissions to member accounts (Option E) are not required; only Control Tower or IAM administrative permissions in the management account are needed for setup.
Thus, the correct answer is A and B -- the SAML metadata from both sides is required for federation.
NEW QUESTION # 38
A CloudOps engineer creates an AWS CloudFormation template to define an application stack that can be deployed in multiple AWS Regions. The CloudOps engineer also creates an Amazon CloudWatch dashboard by using the AWS Management Console. Each deployment of the application requires its own CloudWatch dashboard.
How can the CloudOps engineer automate the creation of the CloudWatch dashboard each time the application is deployed?
Answer: B
Explanation:
According to CloudOps automation and monitoring best practices, CloudWatch dashboards should be provisioned as infrastructure-as-code (IaC) resources using AWS CloudFormation to ensure consistency, repeatability, and version control. AWS CloudFormation supports the AWS::CloudWatch::Dashboard resource, where the DashboardBody property accepts a JSON object describing widgets, metrics, and layout.
By exporting the existing dashboard configuration as JSON and embedding it into the CloudFormation template, every deployment of the application automatically creates its corresponding dashboard. This method aligns with the CloudOps requirement for automated deployment and operational visibility within the same stack lifecycle.
"Use the AWS::CloudWatch::Dashboard resource to create a dashboard from your template. You can include the same JSON you use to define a dashboard in the console." Option A requires manual execution. Options C and D incorrectly reference or reuse existing dashboards, failing to produce unique, deployment-specific dashboards.
NEW QUESTION # 39
An Amazon EC2 instance is running an application that uses Amazon Simple Queue Service (Amazon SQS) queues. A CloudOps engineer must ensure that the application can read, write, and delete messages from the SQS queues.
Which solution will meet these requirements in the MOST secure manner?
Answer: A
Explanation:
Comprehensive Explanation (250-350 words):
The most secure way for an EC2 instance to access AWS services is by using an IAM role attached to the instance. IAM roles eliminate the need for long-term credentials, which reduces the risk of credential leakage and simplifies credential rotation.
Following the principle of least privilege, the IAM policy attached to the role should grant only the permissions required: sqs:SendMessage, sqs:ReceiveMessage, and sqs:DeleteMessage. Granting broader permissions such as sqs:* violates least privilege and increases security risk.
Options A and B rely on IAM users and static credentials, which are not recommended for applications running on EC2. Option C grants excessive permissions.
Therefore, attaching an EC2 IAM role with only the required SQS permissions is the most secure solution.
NEW QUESTION # 40
A company hosts a web application on an Amazon EC2 instance. Users report that the web application is occasionally unresponsive.
Amazon CloudWatch metrics indicate that the CPU utilization is 100% during these times. A SysOps administrator must implement a solution to monitor for this issue.
Which solution will meet this requirement?
Answer: C
Explanation:
The user's symptom is 100% CPU utilization during unresponsiveness, and CloudWatch monitors CPUUtilization metrics by default (with optional detailed monitoring). Setting a CloudWatch alarm on CPU utilization provides real-time detection of high CPU and can trigger automated actions or notifications to respond quickly. This is the standard, scalable way to monitor and alert on CPU pressure for EC2 instances.
