ANS-C01 Question 87
Single answerYou are designing a load balancing solution for a distributed application hosted on Amazon EC2 instances. The application communicates using the GENEVE protocol and requires consistent performance when handling custom traffic encapsulation. Which target type should you configure in your load balancer target group to meet this requirement?
- A
Instance
- B
IP
- C
Lambda
- D
GENEVE
Show answer and explanation
Correct answer: D
Explanation
The GENEVE protocol is a custom encapsulation protocol often used in advanced networking scenarios. When configuring a load balancer target group, choosing the correct target type is crucial to ensure compatibility with the protocol in use. In this case, the 'GENEVE' target type is the appropriate choice as it natively supports the protocol, while the other options either lack the required protocol support or are unrelated to the scenario.
- A. Incorrect.
The 'Instance' target type allows the load balancer to route traffic to specific EC2 instances based on their instance IDs. However, it does not natively support the GENEVE protocol, which is required in this scenario.
- B. Incorrect.
The 'IP' target type enables routing based on IP addresses, allowing flexibility in targeting resources outside of EC2. However, it also does not natively support the GENEVE protocol.
- C. Incorrect.
The 'Lambda' target type is used for serverless workloads, where the load balancer routes requests to AWS Lambda functions. This is not suitable for protocols like GENEVE or scenarios requiring EC2 instance-based traffic.
- D. Correct.
The 'GENEVE' target type is specifically designed to support the GENEVE protocol. It allows the load balancer to handle traffic encapsulation and meet the application's requirement for protocol-specific support.
