You currently have deployed a set of t2.medium EC2 Instances. There is a requirement now mentioning that low latency and high throughput is established between these instances. How can you accomplish this whilst minimizing downtime? Choose 3 answers from the options given below.

Answer options:

A.Stop and restart the instances in a placement group
B.Create AMI’s from the instances
C.Launch new t2.medium instances from the AMI’s
D.Launch new m4.large instances from the AMI’s
E.Ensure the new instances are launched in a placement group

Answer – B,D and E
A placement group is a logical grouping of instances within a single Availability Zone. Placement groups are recommended for applications that benefit from low network latency, high network throughput, or both
To ensure minimum downtime, create AMI’s out of the instances so that new instances can be launched faster.
There is a restriction on which instance types can be used for EC2 Instances in a placement group. T2.medium instances cannot be used in a placement group.
