Launch instances in a separate AZ and add instances to the existing ELB. 


Q152. - (Topic 2) 

An organization has configured the custom metric upload with CloudWatch. The organization has given permission to its employees to upload data using CLI as well SDK. How can the user track the calls made to CloudWatch? 

A. The user can enable logging with CloudWatch which logs all the activities 

B. Use CloudTrail to monitor the API calls 

C. Create an IAM user and allow each user to log the data using the S3 bucket 

D. Enable detailed monitoring with CloudWatch 

Answer:

Explanation: 

AWS CloudTrail is a web service which will allow the user to monitor the calls made to the Amazon CloudWatch API for the organization’s account, including calls made by the AWS Management Console, Command Line Interface (CLI., and other services. When CloudTrail logging is turned on, CloudWatch will write log files into the Amazon S3 bucket, which is specified during the CloudTrail configuration.

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 perform the following set of operations using the Amazon SQS: 

CreateQueue, ListQueues, DeleteQueue, SendMessage, SendMessageBatch, 

ReceiveMessage, DeleteMessage, DeleteMessageBatch, ChangeMessageVisibility, 

ChangeMessageVisibilityBatch, SetQueueAttributes, GetQueueAttributes, GetQueueUrl, 

AddPermission and RemovePermission. Operations can be performed only by the AWS account owner or an AWS account that the account owner has delegated to. 


Q154. - (Topic 2) 

A user is publishing custom metrics to CloudWatch. Which of the below mentioned statements will help the user understand the functionality better? 

A. The user can use the CloudWatch Import tool 

B. The user should be able to see the data in the console after around 15 minutes 

C. If the user is uploading the custom data, the user must supply the namespace, timezone, and metric name as part of the command 

D. The user can view as well as upload data using the console, CLI and APIs 

Answer:

Explanation: 

AWS CloudWatch supports the custom metrics. The user can always capture the custom data and upload the data to CloudWatch using CLI or APIs. The user has to always include the namespace as a part of the request. However, the other parameters are optional. If the user has uploaded data using CLI, he can view it as a graph inside the console. The data will take around 2 minutes to upload but can be viewed only after around 15 minutes. 


Q155. - (Topic 3) 

A user runs the command “dd if=/dev/zero of=/dev/xvdfbs=1M” on a fresh blank EBS volume attached to a Linux instance. Which of the below mentioned activities is the user performing with the command given above? 

A. Creating a file system on the EBS volume 

B. Mounting the device to the instance 

C. Pre warming the EBS volume 

D. Formatting the EBS volume 

Answer:

Explanation: 

When the user creates a new EBS volume and is trying to access it for the first time it will encounter reduced IOPS due to wiping or initiating of the block storage. To avoid this as well as achieve the best performance it is required to pre warm the EBS volume. For a blank volume attached with a Linux OS, the “dd” command is used to write to all the blocks on the device. In the command “dd if=/dev/zero of=/dev/xvdfbs=1M” the parameter “if =import file” should be set to one of the Linux virtual devices, such as /dev/zero. The “of=output file” parameter should be set to the drive that the user wishes to warm. The “bs” parameter sets the block size of the write operation; for optimal performance, this should be set to 1 MB. 


Q156. - (Topic 3) 

A user has created a subnet in VPC and launched an EC2 instance within it. The user has not selected the option to assign the IP address while launching the instance. Which of the 

below mentioned statements is true with respect to this scenario? 

A. The instance will always have a public DNS attached to the instance by default 

B. The user can directly attach an elastic IP to the instance 

C. The instance will never launch if the public IP is not assigned 

D. The user would need to create an internet gateway and then attach an elastic IP to the instance to connect from internet 

Answer:

Explanation: 

A Virtual Private Cloud (VPC. is a virtual network dedicated to the user’s AWS account. A user can create a subnet with VPC and launch instances inside that subnet. When the user is launching an instance he needs to select an option which attaches a public IP to the instance. If the user has not selected the option to attach the public IP then it will only have a private IP when launched. The user cannot connect to the instance from the internet. If the user wants an elastic IP to connect to the instance from the internet he should create an internet gateway and assign an elastic IP to instance. 


Q157. - (Topic 2) 

A user has configured ELB with three instances. The user wants to achieve High Availability as well as 

redundancy with ELB. Which of the below mentioned AWS services helps the user achieve this for ELB? 

A. Route 53 

B. AWS Mechanical Turk 

C. Auto Scaling 

D. AWS EMR 

Answer:

Explanation: 

The user can provide high availability and redundancy for applications running behind Elastic Load Balancer by enabling the Amazon Route 53 Domain Name System (DNS. failover for the load balancers. Amazon Route 53 is a DNS service that provides reliable routing to the user’s infrastructure. 


Q158. - (Topic 3)

A. TLS 1.3 

B. TLS 1.2 

C. SSL 2.0 

D. SSL 3.0 

Answer:

Explanation: 

Elastic Load Balancing uses a Secure Socket Layer (SSL. negotiation configuration which is known as a Security Policy.

Elastic Load Balancing supports the following versions of the SSL protocol: TLS 1.2 TLS 1.1 TLS 1.0 SSL 3.0 SSL 2.0 


Q159. - (Topic 3) 

A user has moved an object to Glacier using the life cycle rules. The user requests to restore the archive after 6 months. When the restore request is completed the user accesses that archive. Which of the below mentioned statements is not true in this condition? 

A. The archive will be available as an object for the duration specified by the user during the restoration request 

B. The restored object’s storage class will be RRS 

C. The user can modify the restoration period only by issuing a new restore request with the updated period 

D. The user needs to pay storage for both RRS (restored. and Glacier (Archive. Rates 

Answer:

Explanation: 

AWS Glacier is an archival service offered by AWS. AWS S3 provides lifecycle rules to archive and restore objects from S3 to Glacier. Once the object is archived their storage class will change to Glacier. If the user sends a request for restore, the storage class will still be Glacier for the restored object. The user will be paying for both the archived copy as well as for the restored object. The object is available only for the duration specified in the restore request and if the user wants to modify that period, he has to raise another restore request with the updated duration. 


Q160. - (Topic 3) 

A user has enabled termination protection on an EC2 instance. The user has also set Instance initiated 

shutdown behaviour to terminate. When the user shuts down the instance from the OS, what will happen? 

A. The OS will shutdown but the instance will not be terminated due to protection 

B. It will terminate the instance 

C. It will not allow the user to shutdown the instance from the OS D. It is not possible to set the termination protection when an Instance initiated shutdown is set to Terminate 

Answer:

Explanation: 

It is always possible that someone can terminate an EC2 instance using the Amazon EC2 console, command line interface or API by mistake. If the admin wants to prevent the instance from being accidentally terminated, he can enable termination protection for that instance. The user can also setup shutdown behaviour for an EBS backed instance to guide the instance on what should be done when he initiates shutdown from the OS using Instance initiated shutdown behaviour. If the instance initiated behaviour is set to terminate and the user shuts off the OS even though termination protection is enabled, it will still terminate the instance.
