A user has configured EBS volume with PIOPS. The user is not experiencing the optimal throughput. Which of the following could not be factor affecting I/O performance of that EBS volume?
Correct Answer:C
If the user is not experiencing the expected IOPS or throughput that is provisioned, ensure that the EC2 bandwidth is not the limiting factor, the instance is EBS-optimized (or include 10 Gigabit network
connectMty) and the instance type EBS dedicated bandwidth exceeds the IOPS more than he has provisioned.

How much memory does the cr1.8xIarge instance type provide?
Correct Answer:D
The CR1 instances are part of the memory optimized instances. They offer lowest cost per GB RAM among all the AWS instance families. CR1 instances are part of the new generation of memory optimized instances, which can offer up to 244 GB RAM and run on faster CPUs (Intel Xeon E5-2670 with NUMA support) in comparison to the NI2 instances of the same family. They support cluster networking for bandwidth intensive applications. cr1.8x|arge is one of the largest instance types of the CR1 family, which can offer 244 GB RAM.
