question 133

Multiple Choice

A company is managing a website with a global user base hosted on Amazon EC2 with an Application Load Balancer (ALB) . To reduce the load on the web servers, a SysOps administrator configures an Amazon CloudFront distribution with the ALB as the origin. After a week of monitoring the solution, the administrator notices that requests are still being served by the ALB and there is no change in the web server load. What are possible causes for this problem? (Choose two.)

• A) CloudFront does not have the ALB configured as the origin access identity.
• B) The DNS is still pointing to the ALB instead of the CloudFront distribution.
• C) The ALB security group is not permitting inbound traffic from CloudFront.
• D) The default, minimum, and maximum Time to Live (TTL) are set to 0 seconds on the CloudFront distribution.
• E) The target groups associated with the ALB are configured for sticky sessions.

Definitions:

Trans-1,2-Dimethylcyclohexane

A cyclohexane molecule with methyl groups located on opposite sides (trans) at the 1 and 2 positions on the ring.

Stable Conformation

A molecular form in which the compound has the lowest possible energy level, thus being more energetically favorable and less reactive.

Chair Conformations

A term used in organic chemistry to describe the most stable form of a cyclohexane ring, resembling a chair, due to minimal steric strain.

Axial Methyl

A methyl group attached to a cyclohexane ring in a position parallel to the axis of the ring, leading to higher steric strain compared to equatorial positions.
