Which of the following is a cause of this?

A SysOps administrator is trying to set up an Amazon Route 53 domain name to route traffic to a website hosted on Amazon S3. The domain name of the website is www.anycompany.com and the S3 bucket name is anycompany-static. After the record set is set up in Route 53, the domain name www.anycompany.com does not seem to work, and the static website is not displayed in the browser.

Which of the following is a cause of this?
A . The S3 bucket must be configured with Amazon CloudFront first.
B . The Route 53 record set must have an IAM role that allows access to the S3 bucket.
C . The Route 53 record set must be in the same region as the S3 bucket.
D . The S3 bucket name must match the record set name in Route 53.

Answer: C

Explanation:

Step-by-Step

Understand the Problem:

The application on a general-purpose EC2 instance experiences performance issues during I/O intensive tasks.

High VolumeQueueLength indicates a bottleneck in I/O operations.

Analyze the Requirements:

Improve disk I/O performance to handle intensive read/write operations.

Evaluate the Options:

Option A: Modify the instance type to be storage optimized.

This could help but may not be necessary if increasing IOPS on the EBS volume resolves the issue.

Option B: Deselect Auto-Enable Volume I/O.

This option is not relevant to addressing high VolumeQueueLength.

Option C: Modify the volume properties to increase the IOPS.

Increasing IOPS directly addresses the I/O performance bottleneck.

Option D: Enable enhanced networking.

Enhanced networking improves network performance but not disk I/O performance.

Select the Best Solution:

Option C: Increasing the IOPS of the EBS volume directly addresses the high VolumeQueueLength and improves I/O performance.

Optimizing EBS Performance

Modifying the volume properties to increase the IOPS ensures that the application can handle intensive read/write operations more effectively.
