Question #86

A system admin is managing buckets, objects and folders with AWS S3. Which of the below mentioned statements is true and should be taken in consideration by the sysadmin?

  • A. The folders support only ACL
  • B. Both the object and bucket can have an Access Policy but folder cannot have policy
  • C. Folders can have a policy
  • D. Both the object and bucket can have ACL but folders cannot have ACL

Correct Answer: D
Amazon S3 Access Control Lists (ACLs) enable you to manage access to buckets and objects. Each bucket and object has an ACL attached to it as a subresource. It defines which AWS accounts or groups are granted access and the type of access. When a request is received against a resource, Amazon S3 checks the corresponding ACL to verify the requester has the necessary access permissions.

Question #87

A user has created an ELB with three instances. How many security groups will ELB create by default?

  • A. 3
  • B. 5
  • C. 2
  • D. 1

Correct Answer: C
Elastic Load Balancing provides a special Amazon EC2 source security group that the user can use to ensure that back-end EC2 instances receive traffic only from Elastic Load Balancing. This feature needs two security groups: the source security group and a security group that defines the ingress rules for the back-end instances. To ensure that traffic only flows between the load balancer and the back-end instances, the user can add or modify a rule to the back-end security group which can limit the ingress traffic. Thus, it can come only from the source security group provided by Elastic Load Balancing.

Question #88

An organization has created 50 IAM users. The organization wants that each user can change their password but cannot change their access keys. How can the organization achieve this?

  • A. The organization has to create a special password policy and attach it to each user
  • B. The root account owner has to use CLI which forces each IAM user to change their password on first login
  • C. By default each IAM user can modify their passwords
  • D. The root account owner can set the policy from the IAM console under the password policy screen

Correct Answer: D
With AWS IAM, organizations can use the AWS Management Console to display, create, change or delete a password policy. As a part of managing the password policy, the user can enable all users to manage their own passwords. If the user has selected the option which allows the IAM users to modify their password, he does not need to set a separate policy for the users. This option in the AWS console allows changing only the password.

Question #89

A user has created a photo editing software and hosted it on EC2. The software accepts requests from the user about the photo format and resolution and sends a message to S3 to enhance the picture accordingly.
Which of the below mentioned AWS services will help make a scalable software with the AWS infrastructure in this scenario?

  • A. AWS Glacier
  • B. AWS Elastic Transcoder
  • C. AWS Simple Notification Service
  • D. AWS Simple Queue Service

Correct Answer: D
Amazon Simple Queue Service (SQS. is a fast, reliable, scalable, and fully managed message queuing service. SQS provides a simple and cost-effective way to decouple the components of an application. The user can configure SQS, which will decouple the call between the EC2 application and S3. Thus, the application does not keep waiting for S3 to provide the data.

Question #90

An application is generating a log file every 5 minutes. The log file is not critical but may be required only for verification in case of some major issue. The file should be accessible over the internet whenever required.
Which of the below mentioned options is a best possible storage solution for it?

Related:  AWS - History
  • A. AWS S3
  • B. AWS Glacier
  • C. AWS RDS
  • D. AWS RRS

Correct Answer: D
Amazon S3 stores objects according to their storage class. There are three major storage classes: Standard,
Reduced Redundancy Storage and Glacier. Standard is for AWS S3 and provides very high durability.
However, the costs are a little higher. Glacier is for archival and the files are not available over the internet.
Reduced Redundancy Storage is for less critical files. Reduced Redundancy is little cheaper as it provides less durability in comparison to S3. In this case since the log files are not mission critical files, RRS will be a better option.
