Q1. A user has set an IAM policy where it allows all requests if a request from IP 10.10.10.1/32. Another policy allows all the requests between 5 PM to 7 PM. What will happen when a user is requesting access from IP 10.10.10.1/32 at 6 PM?
A. IAM will throw an error for policy conflict
B. It is not possible to set a policy based on the time or IP
C. It will deny access
D. It will allow access
Answer: D
Explanation:
With regard to IAM, when a request is made, the AWS service decides whether a given request should be allowed or denied. The evaluation logic follows these rules:
By default, all requests are denied. (In general, requests made using the account credentials for resources in the account are always allowed.)
An explicit allow policy overrides this default. An explicit deny policy overrides any allows. Reference:

Q3. A user has created an application which sends data to a log file. The server hosting the log files can be unavailable due to any reason. The user wants to make it so that whenever the log server is up it should be receMng the messages. Which of the below mentioned AWS services helps achieve this functionality?
A. AWS Simple Workflow
B. AWS Simple Task Service
C. AWS Simple Notification Service
D. AWS Simple Queue Service
Answer: D
Explanation:
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 use SQS to transmit any volume of data without losing messages or requiring other services to always be available. Using SQS, the application has to just send the data to SQS and SQS transmits it to the log file whenever it is available.

Q5. A user has launched five instances with ELB. How can the user add the sixth EC2 instance to ELB?
A. The user can add the sixth instance on the fly.
B. The user must stop the ELB and add the sixth instance.
C. The user can add the instance and change the ELB config file.
D. The ELB can only have a maximum of five instances.
Answer: A
Explanation:
Elastic Load Balancing automatically distributes incoming traffic across multiple EC2 instances. You create a load balancer and register instances with the load balancer in one or more Availability Zones. The load balancer serves as a single point of contact for clients. This enables you to increase the availability of your application. You can add and remove EC2 instances from your load balancer as your needs change, without disrupting the overall flow of information.

Q8. You have been given a scope to deploy some AWS infrastructure for a large orgAMsation. The requirements are that you will have a lot of EC2 instances but may need to add more when the average utilization of your Amazon EC2 fileet is high and conversely remove them when CPU utilization is low. Which AWS services would be best to use to accomplish this?
A. Amazon CIoudFront, Amazon CIoudWatch and Elastic Load Balancing.
B. Auto Scaling, Amazon CIoudWatch and AWS CIoudTraiI.
C. Auto Scaling, Amazon CIoudWatch and Elastic Load Balancing.
D. Auto Scaling, Amazon CIoudWatch and AWS Elastic Beanstalk
Answer: C
Explanation:
Auto Scaling enables you to follow the demand curve for your applications closely, reducing the need to manually provision Amazon EC2 capacity in advance. For example, you can set a condition to add new Amazon EC2 instances in increments to the Auto Scaling group when the average utilization of your Amazon EC2 fileet is high; and similarly, you can set a condition to remove instances in the same increments when CPU utilization is low. If you have predictable load changes, you can set a schedule through Auto Scaling to plan your scaling actMties. You can use Amazon CIoudWatch to send alarms to trigger scaling actMties and Elastic Load Balancing to help distribute traffic to your instances within Auto Scaling groups. Auto Scaling enables you to run your Amazon EC2 fileet at optimal utilization. Reference: http://aws.amazon.com/autoscaIing/
Q9. When you use the AWS Elastic Beanstalk console to deploy a new application you’II need to upload a source bundle and it should .
A. Consist of a single .zip file
B. Consist of a single .war file
C. Consist of a single .zip file or .war file
D. Consist of a folder with all files
Answer: C
Explanation:
When you use the AWS Elastic Beanstalk console to deploy a new application or an application version, you’II need to upload a source bundle. Your source bundle must meet the following requirements: Consist of a single .zip file or .war file
Not exceed 512 MB
Not include a parent folder or top-level directory (subdirectories are fine) Reference:

Q10. A user has created a MySQL RDS instance. Which of the below mentioned options is mandatory to configure while creating an instance?
A. MuIti AZ deployment setup
B. Automated backup window
C. Availability Zone
D. Maintenance window
Answer: A
Explanation:
When creating an RDS instance, the user needs to specify whether it is Nlulti AZ or not. If the user does not provide the value for the zone, the maintenance window or automated backup window, RDS will automatically select the value.

Q11. How do you configure SQS to support longer message retention?
A. Set the lVIessageRetentionPeriod attribute using the SetQueueAttributes method
B. Using a Lambda function
C. You can't. It is set to 14 days and cannot be changed
D. You need to request it from AWS
Answer: A
Explanation:
To configure the message retention period, set the lVIessageRetentionPeriod attribute using the SetQueueAttributes method. This attribute is used to specify the number of seconds a message will be retained by SQS. Currently the default value for the message retention period is 4 days. Using the lVIessageRetentionPeriod attribute, the message retention period can be set anywhere from 60 seconds (1 minute), up to 1209600 seconds (14 days).

Q12. Regarding Amazon SNS, to begin using Amazon SNS mobile push notifications, you first need that uses one of the supported push notification services: APNS, GCM, or ADM.
A. an access policy for the mobile endpoints
B. to active push notification service of Amazon SNS
C. to know the type of mobile device operating system
D. an app for the mobile endpoints
Answer: D
Explanation:
In Amazon SNS, to begin using Amazon SNS mobile push notifications, you first need an app for the mobile endpoints that uses one of the supported push notification services: APNS, GCM, or ADM. After you've registered and configured the app to use one of these services, you configure Amazon SNS to send push notifications to the mobile endpoints.

Q13. AutoScaIing is configured with 3 AZs. Each zone has 5 instances running. If AutoScaIing wants to terminate an instance based on the policy action, which instance will it terminate first?
A. Terminate the first launched instance
B. Randomly select the instance for termination
C. Terminate the instance from the AZ which does not have a high AWS load
D. Terminate the instance from the AZ which has instances running near to the billing hour
Answer: B
Explanation:
Before Auto Scaling selects an instance to terminate, it first identifies the Availability Zone that has more instances than the other Availability Zones used by the group. If all the Availability Zones have the same number of instances, it identifies a random Availability Zone.

Q14. You are using Amazon SQS and are getting a "Queue Deleted RecentIy" error. What is wrong?
A. The message is too big
B. You have incorrect permissions
C. Another user has deleted the queue
D. If you delete a queue, you need to wait for at least 60 seconds before creating a queue with the same name
Answer: D
Explanation:
If you delete a queue, you need to wait for at least 60 seconds before creating a queue with the same name. Please note that when you delete a queue, the deletion process takes up to 60 seconds. Requests you send to a recently deleted queue might succeed during the 60-second period. For example, a SendlVIessage request might succeed, but after 60 seconds the queue and that message you sent no longer exists.
