An application developer used 6 EC2 instances, 2 each in London, Mumbai, and Oregon for geographical resilience to host the application and now wants to add the instances to a load balancer. Which of the following problems needs to be dealt with?
Must use classic load balancer and not application load balancer
The path based routing will be a cause of concern in the target group
While load balancers are global resources, target groups are not
The instances in a target group (attached to the load balancer) cannot span across multiple regions
You Selected Load balancer and target group are regional resources, they cannot span multiple regions. EC2 on the other hand are availability zone specific resources. The deployment topology will require three LB, 3 TG and perhaps a DNS routing service like Route53.

Assume the following deployment specification -
5 manually created EC2 instances already exists
Load balancer and a target group (TG) with the 5 instances
The TG is attached with an autoscaling group (ASG) and scaling policy is based on CPU
The ASG has been created with "minimum" instance of 2
What is the minimum number of EC2 instances that will be active at any point of time in
the TG even if CPU thresholds are not breached?
None of these
7
Correct Option
5
2
You Selected
T otal number of instances = 5 (Manually created) + 2 (Minimum contribution from the autoscaling group) = 7
Q No: 8
Correct Answer

For a sensor network which transmits daily data to be collected by an application server at predictable intervals, which of the following autoscaling policies would be a better fit to meet this type of workload?
Variable group size
Scale by percentage
Set to a fixed value
You Selected
None of these
For predictable workloads, a fixed number of servers is desirable. The auto scaling group can "maintain" the capacity. If this workload remains the same for long periods of time then perhaps either reserved instances or savings plan can reduce costs.
