Bug: Simulator generating wrong reviews for the question & options

[Ravi Manickam]

Hey Jon, The simulator generates wrong reviews for the question & options see below one of the questions & review I got in the review mode, see the question options & review options its totally different.

so how we can trust this & prepare for AWS exam ?

7. QUESTION

Category: CSAA – Design Secure Applications and Architectures

A Solutions Architect is designing a monitoring application which generates audit logs of all operational activities of the company’s cloud infrastructure. Their IT Security and Compliance team mandates that the application retain the logs for 5 years before the data can be deleted.

How can the Architect meet the above requirement?

Store the audit logs in an EBS volume and then take EBS snapshots every month.

Store the audit logs in a Glacier vault and use the Vault Lock feature.

Store the audit logs in an EFS volume and use Network File System version 4 (NFSv4) file-locking mechanism.

Store the audit logs in an Amazon S3 bucket and enable Multi-Factor Authentication Delete (MFA Delete) on the S3 bucket.

Incorrect

In this scenario, a legacy batch application which has steady-state workloads requires a relational MySQL database. The EBS volume that you should use has to handle a maximum of 450 GB of data and can also be used as the system boot volume for your EC2 instance. Since HDD volumes cannot be used as a bootable volume, we can narrow down our options by selecting SSD volumes. In addition, SSD volumes are more suitable for transactional database workloads, as shown in the table below:

General Purpose SSD (gp2) volumes offer cost-effective storage that is ideal for a broad range of workloads. These volumes deliver single-digit millisecond latencies and the ability to burst to 3,000 IOPS for extended periods of time. AWS designs gp2 volumes to deliver the provisioned performance 99% of the time. A gp2 volume can range in size from 1 GiB to 16 TiB.

Amazon EBS Provisioned IOPS SSD (io1) is incorrect because this is not the most cost-effective EBS type and is primarily used for critical business applications that require sustained IOPS performance.

Amazon EBS Throughput Optimized HDD (st1) is incorrect because this is primarily used for frequently accessed, throughput-intensive workloads. Although it is a low-cost HDD volume, it cannot be used as a system boot volume.

Amazon EBS Cold HDD (sc1) is incorrect. Although Amazon EBS Cold HDD provides lower cost HDD volume compared to General Purpose SSD, it cannot be used as a system boot volume.
