SOA-C02 Question 340
Select 3You are tasked with deploying a high-performance application that requires low-latency networking and high throughput between EC2 instances. Additionally, the application must leverage temporary storage for caching large datasets. Which combination of features should you enable to meet the requirements?
- A
Enable an Elastic Network Adapter (ENA) for enhanced networking
- B
Launch instances in a cluster placement group
- C
Attach Amazon EBS volumes for temporary storage
- D
Use instance store volumes for temporary storage
- E
Enable EC2 Hibernate for faster instance recovery
Show answer and explanation
Correct answers: A, B, D
Explanation
To meet the application's requirements for low-latency networking and high throughput, you should use an Elastic Network Adapter (ENA) and launch instances in a cluster placement group. For temporary storage, instance store volumes are the best choice as they are ephemeral and provide high-speed local storage. EBS volumes and EC2 Hibernate do not fit the requirements for this scenario.
- A. Correct.
Elastic Network Adapter (ENA) provides enhanced networking capabilities, enabling low-latency and high-throughput communication between EC2 instances. This is suitable for high-performance applications.
- B. Correct.
Cluster placement groups allow instances to be placed physically closer together, reducing network latency and increasing throughput. This is ideal for applications requiring tightly coupled nodes.
- C. Incorrect.
Amazon EBS volumes are persistent block storage and are not suitable for temporary storage needs such as caching.
- D. Correct.
Instance store volumes are ephemeral storage directly attached to the host machine, making them ideal for temporary storage like caching large datasets.
- E. Incorrect.
EC2 Hibernate is used to preserve the state of an instance when stopped but does not contribute to performance enhancements or temporary storage.
