Amazon Amazon Certifications SAP-C01 Questions & Answers

• Question 571:

  You create an Amazon Elastic File System (EFS) file system and mount targets for the file system in your Virtual Private Cloud (VPC). Identify the initial permissions you can grant to the group root of your file system.

  A. write-execute-modify

  B. read-execute

  C. read-write-modify

  D. read-write

  Correct Answer: B

  In Amazon EFS, when a file system and mount targets are created in your VPC, you can mount the remote

  file system locally on your Amazon Elastic Compute Cloud (EC2) instance. You can grant permissions to

  the users of your file system.

  The initial permissions mode allowed for Amazon EFS are:

  1.

  read-write-execute permissions to the owner root

  2.

  read-execute permissions to the group root read-execute permissions to others

• Question 572:

  In Amazon Elastic Compute Cloud, you can specify storage volumes in addition to the root device volume when you create an AMI or when launching a new instance using______.

  A. block device mapping

  B. object mapping

  C. batch storage mapping

  D. datacenter mapping

  Correct Answer: A

  When creating an AMI or launching a new instance, you can assign more than one block storage device to

  it.

  This device will be automatically set ready for you through an automated process known as block device

  mapping.

• Question 573:

  A user has launched two EBS backed EC2 instances in the US-East-1a region. The user wants to change the zone of one of the instances. How can the user change it?

  A. It is not possible to change the zone of an instance after it is launched

  B. From the AWS EC2 console, select the Actions - > Change zones and specify the new zone

  C. The zone can only be modified using the AWS CLI

  D. Stop one of the instances and change the availability zone

  Correct Answer: A

  With AWS EC2, when a user is launching an instance he can select the availability zone (AZ) at the time of launch. If the zone is not selected, AWS selects it on behalf of the user. Once the instance is launched, the user cannot change the zone of that instance unless he creates an AMI of that instance and launches a new instance from it.
