A user has configured ELB with Auto Scaling. The user suspended the Auto Scaling terminate process only for a while. What will happen to the availability zone rebalancing process (AZRebalance. during this period?
A. Auto Scaling will not launch or terminate any instances
B. Auto Scaling will allow the instances to grow more than the maximum size
C. Auto Scaling will keep launching instances till the maximum instance size
D. It is not possible to suspend the terminate process while keeping the launch active
Answer: B
Explanation:
Auto Scaling performs various processes, such as Launch, Terminate, Availability Zone Rebalance (AZRebalance. etc. The AZRebalance process type seeks to maintain a balanced number of instances across Availability Zones within a region. If the user suspends the Terminate process, the AZRebalance process can cause the Auto Scaling group to grow up to ten percent larger than the maximum size. This is because Auto Scaling allows groups to temporarily grow larger than the maximum size during rebalancing activities. If Auto Scaling cannot terminate instances, the Auto Scaling group could remain up to ten percent larger than the maximum size until the user resumes the Terminate process type.

A user has launched two EBS backed EC2 instances in the US-East-1a region. The user wants to change the zone of one of the instances. How can the user change it?
A. The zone can only be modified using the AWS CLI
B. It is not possible to change the zone of an instance after it is launched
C. Stop one of the instances and change the availability zone
D. From the AWS EC2 console, select the Actions - > Change zones and specify the new zone
Answer: B
Explanation:
With AWS EC2, when a user is launching an instance he can select the availability zone (AZ. at the time of launch. If the zone is not selected, AWS selects it on behalf of the user. Once the instance is launched, the user cannot change the zone of that instance unless he creates an AMI of that instance and launches a new instance from it.

A user has created an EBS volume of 10 GB and attached it to a running instance. The user is trying to access EBS for first time. Which of the below mentioned options is the correct statement with respect to a first time EBS access?
A. The volume will show a size of 8 GB
B. The volume will show a loss of the IOPS performance the first time
C. The volume will be blank
D. If the EBS is mounted it will ask the user to create a file system
Answer: B
Explanation:
A user can create an EBS volume either from a snapshot or as a blank volume. If the volume is from a snapshot it will not be blank. The volume shows the right size only as long as it is mounted. This shows that the file system is created. When the user is accessing the volume the AWS EBS will wipe out the block storage or instantiate from the snapshot. Thus, the volume will show a loss of IOPS. It is recommended that the user should pre warm the EBS before use to achieve better IO.

A user has launched an EC2 instance store backed instance in the US-East-1a zone. The user created AMI #1 and copied it to the Europe region. After that, the user made a few updates to the application running in the US-East-1a zone. The user makes an AMI#2 after the changes. If the user launches a new instance in Europe from the AMI #1 copy, which of the below mentioned statements is true?
A. The new instance will have the changes made after the AMI copy as AWS just copies the reference of the original AMI during the copying. Thus, the copied AMI will have all the updated data
B. The new instance will have the changes made after the AMI copy since AWS keeps updating the AMI
C. It is not possible to copy the instance store backed AMI from one region to another
D. The new instance in the EU region will not have the changes made after the AMI copy
Answer: D
Explanation:
Within EC2, when the user copies an AMI, the new AMI is fully independent of the source AMI; there is no link to the original (source. AMI. The user can modify the source AMI without affecting the new AMI and vice a versa. Therefore, in this case even if the source AMI is modified, the copied AMI of the EU region will not have the changes. Thus, after copy the user needs to copy the new source AMI to the destination region to get those changes.
