Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q338-Q343):

NEW QUESTION # 338
A company runs several applications in the same AWS account. The applications send logs to Amazon CloudWatch.
A data analytics team needs to collect performance metrics and custom metrics from the applications. The analytics team needs to transform the metrics data before storing the data in an Amazon S3 bucket. The analytics team must automatically collect any new metrics that are added to the CloudWatch namespace.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: A

Explanation:
Amazon CloudWatch metric streams are designed to deliver metrics in near real time to downstream services like Amazon Data Firehose with minimal configuration and management overhead. By configuring a metric stream to include all metrics, you ensure that any newly created performance or custom metrics are automatically included without needing to update filters or code when namespaces or metrics change.
Option B uses a CloudWatch metric stream # Firehose # Lambda # S3 pattern. Firehose natively supports invoking a Lambda function for in-flight transformation of the metric data before final delivery to S3. This satisfies the requirement to transform metrics before storing them and provides a fully managed, serverless pipeline with very little ongoing operational burden.
Option A mentions including metrics from "the application and the CloudWatch namespace," which implies more manual selection and maintenance, potentially missing new metrics if not explicitly added. Options C and D work at the log level, not at the metric level, and would require building additional logic to derive metrics from logs. This is more complex and not aligned with "least operational overhead." Therefore, Option B is the most efficient and scalable solution.


NEW QUESTION # 339
A company has a public application that uses an Amazon API Gateway REST API, an AWS Lambda function, and an Amazon RDS for PostgreSQL DB cluster. Users have recently received error messages as application demand increased.
The company's DevOps engineer discovered that the errors were caused by RDS connection limits being reached. The DevOps engineer also discovered that more than 90% of the API requests are GET requests that read from the DB cluster.
How should the DevOps engineer solve this problem with the LEAST development effort?

Answer: A

Explanation:
The root cause of the problem is that the RDS PostgreSQL instance is exceeding its database connection limit due to high volumes of concurrent GET requests. The most efficient and lowest-effort remediation is to reduce the number of connections that reach the database and serve as many reads as possible from a cache layer. Option B accomplishes both goals with minimal changes to the existing architecture.
First, RDS Proxy manages database connections efficiently by pooling and reusing them. This reduces connection churn and prevents the Lambda function from opening excessive concurrent connections during traffic spikes. RDS Proxy is natively integrated with RDS and requires only minor configuration changes without altering application logic.
Second, enabling API Gateway caching allows caching GET responses directly at the API layer. Because over
90% of requests are GET operations, enabling caching drastically reduces traffic hitting both Lambda and RDS, significantly improving performance and lowering connection pressure.
Option C also improves read scaling, but adding ElastiCache introduces additional infrastructure and requires modifying application code to query Redis before querying the database. This is more complex than enabling API Gateway caching. Options A and D require full database migration, which is far more labor-intensive.
Option B is the simplest, most effective, and most aligned with AWS best practices for reducing RDS connection saturation.


NEW QUESTION # 340
A company is storing 100 GB of log data in .csv format in an Amazon S3 bucket. SQL developers want to query this data and generate graphs to visualize it. The SQL developers also need an efficient, automated way to store metadata from the .csv file. Which combination of steps will meet these requirements with the LEAST amount of effort? (Select THREE.)

Answer: B,E,F


NEW QUESTION # 341
A company has 20 service learns Each service team is responsible for its own microservice. Each service team uses a separate AWS account for its microservice and a VPC with the 192 168 0 0/22 CIDR block. The company manages the AWS accounts with AWS Organizations.
Each service team hosts its microservice on multiple Amazon EC2 instances behind an Application Load Balancer. The microservices communicate with each other across the public internet. The company's security team has issued a new guideline that all communication between microservices must use HTTPS over private network connections and cannot traverse the public internet.
A DevOps engineer must implement a solution that fulfills these obligations and minimizes the number of changes for each service team.
Which solution will meet these requirements?

Answer: C

Explanation:
Explanation
https://aws.amazon.com/blogs/networking-and-content-delivery/connecting-networks-with-overlapping-ip-range Private link is the best option because Transit Gateway doesn't support overlapping CIDR ranges.


NEW QUESTION # 342
A company uses an organization in AWS Organizations to manage multiple AWS accounts in a hierarchical structure. An SCP that is associated with the organization root allows IAM users to be created.
A DevOps team must be able to create IAM users with any level of permissions. Developers must also be able to create IAM users. However, developers must not be able to grant new IAM users excessive permissions.
The developers have the CreateAndManageUsers role in each account. The DevOps team must be able to prevent other users from creating IAM users.
Which combination of steps will meet these requirements? (Select TWO.)

Answer: C,D

Explanation:
To allow developers to create IAM users without granting excessive permissions, the correct solution is to use permissions boundaries, which AWS specifically recommends for restricting delegated administrators such as developers. A permissions boundary defines the maximum permissions that an IAM user or role can delegate.
Step C ensures that each AWS account contains a PermissionBoundaries policy defining the maximum allowed permissions that any developer-created user may receive. This prevents privilege escalation, even if the developer attaches a more powerful policy. This aligns with AWS guidance for restricting privilege escalation within multi-account environments.
Step E ensures that developers can create IAM users but only if they attach the PermissionBoundaries policy as the permissions boundary. By attaching the DeveloperBoundary policy to the CreateAndManageUsers role, developers gain the ability to create users, but they are cryptographically prevented from assigning permissions outside the boundary policy.
Meanwhile, the DevOps team (who are not restricted by the boundary) can still create IAM users with full permissions.
This combination satisfies all constraints:
DevOps team: unrestricted IAM creation
Developers: restricted IAM creation enforced by boundaries
Other users: still blocked from IAM creation by existing SCP


NEW QUESTION # 343
......

The education level of the country has been continuously improved. At present, there are more and more people receiving higher education, and even many college graduates still choose to continue studying in school. Getting the test DOP-C02 certification maybe they need to achieve the goal of the learning process, have been working for the workers, have more qualifications can they provide wider space for development. The DOP-C02 Actual Exam guide can provide them with efficient and convenient learning platform so that they can get the certification as soon as possible in the shortest possible time. A high degree may be a sign of competence, getting the test DOP-C02 certification is also a good choice. When we get enough certificates, we have more options to create a better future.
