- Question 1
An application running on Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones was deployed using an AWS CloudFormation template. The SysOps team has patched the Amazon Machine Image (AMI) version and must update all the EC2 instances to use the new AMI.
How can the SysOps Administrator use CloudFormation to apply the new AMI while maintaining a minimum level of active instances to ensure service continuity?
Show answer & explanation
Correct answer: C
C
- Question 2
A user had aggregated the CloudWatch metric data on the AMI ID. The user observed some abnormal behavior of the CPU utilization metric while viewing the last 2 weeks of data. The user wants to share that data with his manager.
How can the user achieve this easily with the AWS console?
Show answer & explanation
Correct answer: C
C--Explanation:
Amazon CloudWatch provides the functionality to graph the metric data generated either by the AWS services or the custom metric to make it easier for the user to analyze. The console provides the option to save the URL or bookmark it so that it can be used in the future by typing the same URL. The Copy URL functionality is available under the console when the user selects any metric to view. - Question 3
A SysOps Administrator is managing an AWS account where Developers are authorized to launch Amazon EC2 instances to test new code. To limit costs, the Administrator must ensure that the EC2 instances in the account are terminated 24 hours after launch.
How should the Administrator meet these requirements?
Show answer & explanation
Correct answer: B
B
- Question 4
A user is aware that a huge download is occurring on his instance. He has already set the Auto Scaling policy to increase the instance count when the network I/O increases beyond a certain limit.
How can the user ensure that this temporary event does not result in scaling?
Show answer & explanation
Correct answer: A
A--Explanation:
The user may want to stop the automated scaling processes on the Auto Scaling groups either to perform manual operations or during emergency situations. To perform this, the user can suspend one or more scaling processes at any time. Once it is completed, the user can resume all the suspended processes.--

A user has created a VPC with CIDR 20.0.0.0/16 using the wizard. The user has created a public subnet CIDR (20.0.0.0/24. and VPN only subnets CIDR (20.0.1.0/24. along with the VPN gateway (vgw-12345. to connect to the user’s data center.
Which of the below mentioned options is a valid entry for the main route table in this scenario?
Show answer & explanation
Correct answer: C
C--Explanation:
The main route table came with the VPC, and it also has a route for the VPN-only subnet. A custom route table is associated with the public subnet. The custom route table has a route over the Internet gateway (the destination is 0.0.0.0/0, and the target is the Internet gateway).
If you create a new subnet in this VPC, it’s automatically associated with the main route table, which routes its traffic to the virtual private gateway. If you were to set up the reverse configuration (the main route table with the route to the Internet gateway, and the custom route table with the route to the virtual private gateway), then a new subnet automatically has a route to the Internet gateway.--

A user is trying to setup a recurring Auto Scaling process. The user has setup one process to scale up every day at 8 am and scale down at 7 PM. The user is trying to setup another recurring process, which scales up on the 1st of every month at 8 AM and scales down the same day at 7 PM.
What will Auto Scaling do in this scenario?
Show answer & explanation
Correct answer: A
A--Explanation:
Auto Scaling based on a schedule allows the user to scale the application in response to predictable load changes. The user can also configure the recurring schedule action, which will follow the Linux cron format. As per Auto Scaling, a scheduled action must have a unique time value. If the user attempts to schedule an activity at a time when another existing activity is already scheduled, the call will be rejected with an error message noting the conflict. - Question 7
A fleet of servers must send local logs to Amazon CloudWatch.
How should the servers be configured to meet this requirement?
Show answer & explanation
Correct answer: D
D
- Question 8
A user has configured two security groups which allow traffic as given below:
1: SecGrpI:
Inbound on port 80 for 0.0.0.0/0
Inbound on port 22 for 0.0.0.0/02: SecGrp2:
Inbound on port 22 for 10.10.10.1/32If both the security groups are associated with the same instance, which of the below mentioned statements is true?
Show answer & explanation
Correct answer: C
C--Explanation:
A user can attach more than one security group to a single EC2 instance. In this case, the rules from each security group are effectively aggregated to create one set of rules. AWS uses this set of rules to determine whether to allow access or not. Thus, here the rule for port 22 with IP 10.10.10.1/32 will merge with IP 0.0.0.0/0 and open ports 22 and 80 for all.--

What is the main use of EMR?
Show answer & explanation
Correct answer: A
A--Explanation:
Using Amazon EMR, you can instantly provision as much or as little capacity as you like to perform data-intensive tasks for applications such as web indexing, data mining, log file analysis, machine learning, financial analysis, scientific simulation, and bioinformatics research. Amazon EMR lets you focus on crunching or analyzing your data without having to worry about time-consuming set-up, management or tuning of Hadoop clusters or the compute capacity upon which they sit.--

Show answer & explanation
Correct answer: A
A--Explanation:
