21. Frage
A company wants to implement a backup strategy for Amazon EC2 data and multiple Amazon S3 buckets.
Because of regulatory requirements, the company must retain backup files for a specific time period. The company must not alter the files for the duration of the retention period.
Which solution will meet these requirements?
Antwort: A
Begründung:
Explanation
AWS Backup is a fully managed service that allows you to centralize and automate data protection of AWS services across compute, storage, and database. AWS Backup Vault Lock is an optional feature of a backup vault that can help you enhance the security and control over your backup vaults. When a lock is active in Compliance mode and the grace time is over, the vault configuration cannot be altered or deleted by a customer, account/data owner, or AWS. This ensures that your backups are available for you until they reach the expiration of their retention periods and meet the regulatory requirements. References:

22. Frage
A company uses multiple vendors to distribute digital assets that are stored in Amazon S3 buckets The company wants to ensure that its vendor AWS accounts have the minimum access that is needed to download objects in these S3 buckets Which solution will meet these requirements with the LEAST operational overhead?
Antwort: A
Begründung:
Explanation
A cross-account IAM role is a way to grant users from one AWS account access to resources in another AWS account. The cross-account IAM role can have a read-only access policy attached to it, which allows the users to download objects from the S3 buckets without modifying or deleting them. The cross-account IAM role also reduces the operational overhead of managing multiple IAM users and policies in each account. The cross-account IAM role meets all the requirements of the question, while the other options do not. References:

23. Frage
A company has a transaction-processing application that is backed by an Amazon RDS MySQL database.
When the load on the application increases, a large number of database connections are opened and closed frequently, which causes latency for the database transactions.
A solutions architect determines that the root cause of the latency is poor connection handling by the application. The solutions architect cannot modify the application code. The solutions architect needs to manage database connections to improve the database performance during periods of high load.
Which solution will meet these requirements?
Antwort: D
Begründung:
Amazon RDS Proxy is a fully managed database proxy for RDS that makes applications more scalable, more resilient to database failures, and more secure. RDS Proxy pools and shares database connections, allowing applications to open and close connections as needed without overwhelming the database. This is the recommended solution when the application cannot be modified to use connection pooling itself.
AWS Documentation Extract:
"Amazon RDS Proxy helps manage database connections to improve application scalability and performance.
It pools connections and shares them among application clients, which can mitigate issues caused by opening and closing many database connections." (Source: Amazon RDS Proxy documentation) A: Upgrading the instance does not solve connection inefficiency and can be cost-ineffective.
B: Increasing IOPS only helps if storage is a bottleneck, not if connections are the issue.
D: Multi-AZ improves availability, not connection management.
Reference: AWS Certified Solutions Architect - Official Study Guide, RDS Performance and Proxy.
24. Frage
A company discovers that an Amazon DynamoDB Accelerator (DAX) cluster for the company's web application workload is not encrypting data at rest. The company needs to resolve thesecurity issue. Which solution will meet this requirement?
Antwort: D
Begründung:
DAX does not support enabling encryption at rest on an existing cluster. To use encryption at rest, you must create a new DAX cluster with encryption enabled at creation time and migrate workloads accordingly.
25. Frage
A company plans to deploy an application in an Amazon EC2 instance. The application will perform the following tasks:
- Read large datasets from an Amazon S3 bucket.
- Execute multi-stage analysis on the datasets.
- Save the results to Amazon RDS.
During multi-stage analysis, the application will store a large number of temporary files in the instance storage. As the Solutions Architect, you need to recommend the fastest storage option with high I/O performance for the temporary files.
Which of the following options fulfills this requirement?
Antwort: B
Begründung:
Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) Cloud. You can use Amazon EC2 to launch as many or as few virtual servers as you need, configure security and networking, and manage storage. Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes in popularity, reducing your need to forecast traffic.
RAID 0 configuration enables you to improve your storage volumes' performance by distributing the I/O across the volumes in a stripe. Therefore, if you add a storage volume, you get the straight addition of throughput and IOPS. This configuration can be implemented on both EBS or instance store volumes.
Since the main requirement in the scenario is storage performance, you need to use an instance store volume. It uses NVMe or SATA-based SSD to deliver high random I/O performance. This type of storage is a good option when you need storage with very low latency, and you don't need the data to persist when the instance terminates.
Hence, the correct answer is: Configure RAID 0 in multiple instance store volumes.
The option that says: Enable Transfer Acceleration in Amazon S3 is incorrect because S3 Transfer Acceleration is mainly used to speed up the transfer of gigabytes or terabytes of data between clients and an S3 bucket.
The option that says: Configure RAID 1 in multiple instance volumes is incorrect because RAID 1 configuration is used for data mirroring. You need to configure RAID 0 to improve the performance of your storage volumes.
The option that says: Attach multiple Provisioned IOPS SSD volumes in the instance is incorrect because persistent storage is not needed in the scenario. Also, instance store volumes have greater I/O performance than EBS volumes.
