NEW QUESTION 1
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

Answer: C

Explanation: 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:

NEW QUESTION 2
When using Amazon SQS how much data can you store in a message?

• A. 8 KB
• B. 2 KB
• C. 16 KB
• D. 4 KB

Answer: A

Explanation: With Amazon SQS version 2008-01-01, the maximum message size for both SOAP and Query requests is 8KB.
If you need to send messages to the queue that are larger than 8 KB, AWS recommends that you split the information into separate messages. Alternatively, you could use Amazon S3 or Amazon Simp|eDB to hold the information and include the pointer to that information in the Amazon SQS message.
If you send a message that is larger than 8KB to the queue, you will receive a MessageTooLong error with HTTP code 400.

• A. Use instance memory to save session state.

NEW QUESTION 4
In DynamoDB, could you use IAM to grant access to Amazon DynamoDB resources and API actions?

• A. Yes
• B. Depended to the type of access
• C. In DynamoDB there is no need to grant access
• D. No

Answer: A

Explanation: Amazon DynamoDB integrates with AWS Identity and Access Management (IAM). You can use AWS IAM to grant access to Amazon DynamoDB resources and API actions. To do this, you first write an AWS IAM policy, which is a document that explicitly lists the permissions you want to grant. You then attach that policy to an AWS IAM user or role.

• A. CIoudWatch
• B. S3
• C. AutoScaIing
• D. AWS EC2 instances

NEW QUESTION 13
An orgAMzation has created an application which is hosted on the AWS EC2 instance. The application stores images to S3 when the end user uploads to it. The orgAMzation does not want to store the AWS secure credentials required to access the S3 inside the instance. Which of the below mentioned options is a possible solution to avoid any security threat?

• A. Use the IAM role and assign it to the instance.
• B. Since the application is hosted on EC2, it does not need credentials to access S3.
• C. Use the X.509 certificates instead of the access and the secret access keys.
• D. Use the IAM based single sign between the AWS resources and the orgAMzation applicatio

Answer: A

Explanation: The AWS IAM role uses temporary security credentials to access AWS services. Once the role is assigned to an instance, it will not need any security credentials to be stored on the instance. Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html

NEW QUESTION 14
An orgAMzation has 10 departments. The orgAMzation wants to track the AWS usage of each department. Which of the below mentioned options meets the requirement?

• B. Create separate accounts for each department, but use consolidated billing for payment and tracking
• C. Create separate accounts for each department and track them separately
• D. Setup IAM users for each department and track their usage

Answer: B

Explanation: The cost of an IAM user or groups can never be tracked separately for the purpose of billing. The best solution in this case is to create a separate account for each department and use consolidated billing. Reference: http://docs.aws.amazon.com/IAM/|atest/UserGuide/|AM_|ntroduction.htmI

• B. From 10 secs up to 7 days
