Question 37

What is the role of the PoIIForTask action when it is called by a task runner in AWS Data Pipeline?

A. It is used to retrieve the pipeline definition.

B. It is used to report the progress of the task runner to AWS Data Pipeline.

C. It is used to receive a task to perform from AWS Data Pipeline.

D. It is used to inform AWS Data Pipeline of the outcome when the task runner completes a tas

Correct Answer:C
Task runners call Po||ForTask to receive a task to perform from AWS Data Pipeline. If tasks are ready in the work queue, PoIIForTask returns a response immediately. If no tasks are available in the queue, PoIIForTask uses long-polling and holds on to a poll connection for up to 90 seconds, during which time any newly scheduled tasks are handed to the task agent. Your remote worker should not call PoIIForTask again on the same worker group until it receives a response, and this may take up to 90 seconds.

Question 38

An organization is setting up a multi-site solution where the application runs on premise as well as on AWS to achieve the minimum recovery time objective(RTO). Which of the below mentioned configurations will not meet the requirements of the multi-site solution scenario?

A. Configure data replication based on RTO.

B. Keep an application running on premise as well as in AWS with full capacity.

C. Setup a single DB instance which will be accessed by both sites.

D. Setup a weighted DNS service like Route 53 to route traffic across site

Correct Answer:C
AWS has many solutions for DR(Disaster recovery) and HA(High Availability). When the organization wants to have HA and DR with multi-site solution, it should setup two sites: one on premise and the other on AWS with full capacity. The organization should setup a weighted DNS service which can route traffic to both sites based on the weightage. When one of the sites fails it can route the entire load to another site. The organization would have minimal RTO in this scenario. If the organization setups a single DB instance, it will not work well in failover.
Instead they should have two separate DBs in each site and setup data replication based on RTO(recovery time objective )of the organization.

Question 39

An organization is planning to host a web application in the AWS VPC. The organization does not want to host a database in the public cloud due to statutory requirements. How can the organization setup in this scenario?

A. The organization should plan the app server on the public subnet and database in the organization’s data center and connect them with the VPN gateway.

B. The organization should plan the app server on the public subnet and use RDS with the private subnet for a secure data operation.

C. The organization should use the public subnet for the app server and use RDS with a storage gateway to access as well as sync the data securely from the local data center.

D. The organization should plan the app server on the public subnet and database in a private subnet so it will not be in the public cloud.

Correct Answer:A
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account.
The user can create subnets as per the requirement within a VPC. If the user wants to connect VPC from his own data centre, he can setup a public and VPN only subnet which uses hardware VPN access to
connect with his data centre. When the user has configured this setup with Wizard, it will create a virtual private gateway to route all the traffic of the VPN subnet.
If the virtual private gateway is attached with VPC and the user deletes the VPC from the console it will first automatically detach the gateway and only then delete the VPC.

Question 40

How does AWS Data Pipeline execute actMties on on-premise resources or AWS resources that you manage?

A. By supplying a Task Runner package that can be installed on your on-premise hosts

B. None of these

C. By supplying a Task Runner file that the resources can access for execution

D. By supplying a Task Runnerjson script that can be installed on your on-premise hosts

Correct Answer:A
To enable running actMties using on-premise resources, AWS Data Pipeline does the following: It supply a Task Runner package that can be installed on your on-premise hosts.
This package continuously polls the AWS Data Pipeline service for work to perform.
When it’s time to run a particular actMty on your on-premise resources, it will issue the appropriate command to the Task Runner.

Question 42

An organization has created 5 IAM users. The organization wants to give them the same login ID but different passwords. How can the organization achieve this?

A. The organization should create each user in a separate region so that they have their own URL to login

B. The organization should create a separate login ID but give the IAM users the same alias so that each one can login with their alias

C. It is not possible to have the same login ID for multiple IAM users of the same account

D. The organization should create various groups and add each user with the same login ID to different group

E. The user can login with their own group ID

Correct Answer:C
AWS Identity and Access Management is a web service which allows organizations to manage users and user permissions for various AWS services. Whenever the organization is creating an IAM user, there should be a unique ID for each user. It is not possible to have the same login ID for multiple users. The names of users, groups, roles, instance profiles must be alphanumeric, including the following common characters: plus (+), equal (=), comma (,), period (.), at (@), and dash (-).
