Q81. When should a user try to Force Detach an EBS volume?

A. If the volume is stuck in a detaching state

B. If the volume is not accessible from the instance

C. If the volume is not unmounted and the user still wants to detach

D. If the volume is a root volume 

Answer: A

Explanation:

If an EBS volume stays in the detaching state, the user can force the detachment by clicking Force Detach. Forcing the detachment can lead to either data loss or a corrupted file system. The user should use this option only as a last resort to detach a volume from a failed instance or if he is detaching a volume with the intention of deleting it.

Q82. In relation to Amazon SQS, how can you ensure that messages are delivered in order?

A. Increase the size of your queue

B. Send them with a timestamp

C. Give each message a unique id.

D. AWS cannot guarantee that you will receive messages in the exact order you sent them 

Answer: D

Explanation:

Amazon SQS makes a best effort to preserve order in messages, but due to the distributed nature of the queue, AWS cannot guarantee that you will receive messages in the exact order you sent them. You typically place sequencing information or timestamps in your messages so that you can reorder them upon receipt.

C. Amazon SQS is a distributed queuing system that is optimized for horizontal scalability, not for single-threaded sending or receMng speeds.

D. Amazon SQS is a distributed queuing system that is optimized for vertical scalability and for single-threaded sending or receMng speeds.

Answer:

Explanation:

Amazon SQS is a distributed queuing system that is optimized for horizontal scalability, not for

single-threaded sending or receMng speeds. A single client can send or receive Amazon SQS messages at a rate of about 5 to 50 messages per second. Higher receive performance can be achieved by requesting multiple messages (up to 10) in a single call. It may take several seconds before a message that has been to a queue is available to be received.
