Question 116

A bucket owner has allowed another account’s IAM users to upload or access objects in his bucket. The IAM user of Account A is trying to access an object created by the IAM user of account B. What will happen in this scenario?

A. The bucket policy may not be created as S3 will give error due to conflict of Access Rights
B. It is not possible to give permission to multiple IAM users
C. AWS S3 will verify proper rights given by the owner of Account A, the bucket owner as well as by the IAM user B to the object
D. It is not possible that the IAM user of one account accesses objects of the other IAM user

Correct Answer:C
If a IAM user is trying to perform some action on an object belonging to another AWS user’s bucket, S3 will verify whether the owner of the IAM user has given sufficient permission to him. It also verifies the policy for the bucket as well as the policy defined by the object owner.

Question 117

How long can you keep your Amazon SQS messages in Amazon SQS queues?

A. From 120 secs up to 4 weeks
B. From 10 secs up to 7 days
C. From 60 secs up to 2 weeks
D. From 30 secs up to 1 week

Correct Answer:C
The SQS message retention period is configurable and can be set anywhere from 1 minute to 2 weeks. The default is 4 days and once the message retention limit is reached your messages will be automatically deleted. The option for longer message retention provides greater filexibility to allow for longer intervals between message production and consumption.

Question 118

You are building an online store on AWS that uses SQS to process your customer orders. Your backend system needs those messages in the same sequence the customer orders have been put in. How can you achieve that?

A. You can do this with SQS but you also need to use SWF
B. Messages will arrive in the same order by default
C. You can use sequencing information on each message
D. It is not possible to do this with SQS

Correct Answer:C
Amazon SQS is engineered to always be available and deliver messages. One of the resulting tradeoffs is that SQS does not guarantee first in, first out delivery of messages. For many distributed applications, each message can stand on its own, and as long as all messages are delivered, the order is not important. If your system requires that order be preserved, you can place sequencing information in each message,
so that you can reorder the messages when the queue returns them. Reference:

Question 120

What is the maximum size for messages stored in SQS?

A. 256KB
B. 128KB
C. 1024KB
D. 64KB

Correct Answer:A
By default, SQS queues allow you to send the largest supported payload size, currently 256KB. You can choose to specify a limit on how many bytes can be sent per payload, using the lVIaximumlVIessageSize attribute of the SetQueueAttributes method.
