Exam AWS Certified Solutions Architect - Professional topic 1 question 469 discussion

Host Affinity is configured at the instance level. It establishes a launch relationship between an instance and a Dedicated Host. (This set which host the instance can run on) Auto-placement allows you to manage whether instances that you launch are launched onto a specific host, or onto any available host that has matching configurations. Auto-placement must be configured at the host level. (This sets which instance the host can run.) When affinity is set to Host, an instance launched onto a specific host always restarts on the same host if stopped. This applies to both targeted and untargeted launches. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/how-dedicated-hosts-work.html

Dedicated host, so B

I hope to have several of these straightforward questions on the real test!

Based on all comments

Why is it C instead of A?

B. Run the instance on a dedicated host with Host Affinity set to Host.

B is right answer based on requirement.

I go with B

B for sure When affinity is set to Host, an instance launched onto a specific host always restarts on the same host if stopped. This applies to both targeted and untargeted launches. When affinity is set to Off, and you stop and restart the instance, it can be restarted on any available host. However, it tries to launch back onto the last Dedicated Host on which it ran (on a best-effort basis).

B is correct.

Correct answer is B. Host Affinity

I'll go with B
