Q17. - (Topic 3)
A user is observing the EC2 CPU utilization metric on CloudWatch. The user has observed some interesting patterns while filtering over the 1 week period for a particular hour. The user wants to zoom that data point to a more granular period. How can the user do that easily with CloudWatch?
A. The user can zoom a particular period by selecting that period with the mouse and then releasing the mouse
B. The user can zoom a particular period by double clicking on that period with the mouse
C. The user can zoom a particular period by specifying the aggregation data for that period
D. The user can zoom a particular period by specifying the period in the Time Range
Answer: A
Q18. - (Topic 2)
A user is trying to connect to a running EC2 instance using SSH. However, the user gets a connection time out error. Which of the below mentioned options is not a possible reason for rejection?
A. The access key to connect to the instance is wrong
B. The security group is not configured properly
C. The private key used to launch the instance is not correct
D. The instance CPU is heavily loaded
Answer: A
Explanation:
If the user is trying to connect to a Linux EC2 instance and receives the connection time out error the probable reasons are: Security group is not configured with the SSH port The private key pair is not right The user name to login is wrong The instance CPU is heavily loaded, so it does not allow more connections
Q19. - (Topic 2)
A user has configured the Auto Scaling group with the minimum capacity as 3 and the maximum capacity as 5. When the user configures the AS group, how many instances will Auto Scaling launch?
A. 3
B. 0
C. 5
D. 2
Answer: C
Q20. - (Topic 3)
An organization has configured Auto Scaling with ELB. There is a memory issue in the application which is causing CPU utilization to go above 90%. The higher CPU usage triggers an event for Auto Scaling as per the scaling policy. If the user wants to find the root cause inside the application without triggering a scaling activity, how can he achieve this?
A. Stop the scaling process until research is completed
B. It is not possible to find the root cause from that instance without triggering scaling
C. Delete Auto Scaling until research is completed
D. Suspend the scaling process until research is completed
Answer: D
Explanation:
Auto Scaling allows the user to suspend and then resume one or more of the Auto Scaling processes in the Auto Scaling group. This is very useful when the user wants to investigate a configuration problem or some other issue, such as a memory leak with the web application and then make changes to the application, without triggering the Auto Scaling process.
Q21. - (Topic 2)
A user has enabled detailed CloudWatch metric monitoring on an Auto Scaling group. Which of the below
mentioned metrics will help the user identify the total number of instances in an Auto Scaling group cluding pending, terminating and running instances?
A. GroupTotalInstances
B. GroupSumInstances
C. It is not possible to get a count of all the three metrics together. The user has to find the individual number of running, terminating and pending instances and sum it
D. GroupInstancesCount
Answer: A
Explanation:
CloudWatch is used to monitor AWS as well as the custom services. For Auto Scaling, CloudWatch provides various metrics to get the group information, such as the Number of Pending, Running or Terminating instances at any moment. If the user wants to get the total number of Running, Pending and Terminating instances at any moment, he can use the GroupTotalInstances metric.
Q22. - (Topic 3)
A user is planning to set up the Multi AZ feature of RDS. Which of the below mentioned conditions won't take advantage of the Multi AZ feature?
A. Availability zone outage
B. A manual failover of the DB instance using Reboot with failover option
C. Region outage
D. When the user changes the DB instance’s server type
Answer: C
Explanation:
Amazon RDS when enabled with Multi AZ will handle failovers automatically. Thus, the user can resume database operations as quickly as possible without administrative intervention. The primary DB instance switches over automatically to the standby replica if any of the following conditions occur: An Availability Zone outage The primary DB instance fails The DB instance's server type is changed The DB instance is undergoing software patching A manual failover of the DB instance was initiated using Reboot with failover
Q23. - (Topic 1)
You are tasked with setting up a cluster of EC2 Instances for a NoSQL database. The database requires random read IO disk performance up to a 100,000 IOPS at 4KB block side per node.
Which of the following EC2 instances will perform the best for this workload?
A. A High-Memory Quadruple Extra Large (m2.4xlarge) with EBS-Optimized set to true and a PIOPs EBS volume
B. A Cluster Compute Eight Extra Large (cc2.8xlarge) using instance storage
C. High I/O Quadruple Extra Large (hi1.4xlarge) using instance storage
D. A Cluster GPU Quadruple Extra Large (cg1.4xlarge) using four separate 4000 PIOPS EBS volumes in a RAID 0 configuration
Answer: C
Explanation: Explanation: Reference:

Q24. - (Topic 2)
A user has received a message from the support team that an issue occurred 1 week back between 3 AM to 4 AM and the EC2 server was not reachable. The user is checking the CloudWatch metrics of that instance. How can the user find the data easily using the CloudWatch console?
A. The user can find the data by giving the exact values in the time Tab under CloudWatch metrics
B. The user can find the data by filtering values of the last 1 week for a 1 hour period in the Relative tab under CloudWatch metrics
C. It is not possible to find the exact time from the console. The user has to use CLI to provide the specific time
D. The user can find the data by giving the exact values in the Absolute tab under CloudWatch metrics
Answer: D
Explanation:
If the user is viewing the data inside the CloudWatch console, the console provides options to filter values either using the relative period, such as days /hours or using the Absolute tab where the user can provide data with a specific date and time. The console also provides the option to search using the local timezone under the time range caption in the console.
