NEW QUESTION # 454
A developer is trying to make API calls using AWS SDK. The IAM user credentials used by the application require multi-factor authentication for all API calls. Which method should the developer use to access the multi-factor authentication protected API?
Answer: D
Explanation:
When IAM user credentials require multi-factor authentication, the application must first obtain temporary credentials that include MFA validation. Calling the AWS Security Token Service GetSessionToken API with the MFA code generates short-term credentials that can be used to make authenticated AWS SDK API calls while enforcing MFA requirements.
NEW QUESTION # 455
A developer is re-architecting a caching solution that currently uses an Amazon ElastiCache (Redis OSS) cluster that has cluster mode enabled to store product information. The existing solution experiences significant load. All cached product data expires at the same time, which results in additional pressure on the backend database and poor performance for end users. The developer must resolve the performance issues in a way that maintains data freshness. Which solution will meet these requirements?
Answer: C
Explanation:
Adding a small random variation to each product's TTL prevents many cache entries from expiring simultaneously. This distributes cache refreshes over time, avoids a cache stampede against the backend database, and preserves data freshness through normal expiration.
NEW QUESTION # 456
A data visualization company wants to strengthen the security of its core applications The applications are deployed on AWS across its development staging, pre-production, and production environments. The company needs to encrypt all of its stored sensitive credentials The sensitive credentials need to be automatically rotated Aversion of the sensitive credentials need to be stored for each environment Which solution will meet these requirements in the MOST operationally efficient way?
Answer: B
Explanation:
Explanation
AWS Secrets Manager is the best option for managing sensitive credentials across multiple environments, as it provides automatic secret rotation, auditing, and monitoring features. It also allows storing environment-specific credentials in separate secrets, which can be accessed by the applications using the SDK or CLI. AWS Systems Manager Parameter Store does not have built-in secret rotation capability, and it requires creating individual parameters or storing the entire credential set as JSON object. Configuring the environment variables in the application code is not a secure or scalable solution, as it exposes the credentials to anyone who can access the code. References
