350-501 Question #547: Real Exam Question with Answer & Explanation
The correct answer is B: Configure encoding self-describing-gpb under destination-group. To provide detailed telemetry data from nearly 2000 devices without encryption, the team should configure gRPC as the protocol without TLS and use self-describing-gpb for efficient data encoding.
Question
Refer to the exhibit. The networking team must design a solution to provide as much detail about the network as possible. The network has almost 2000 network devices, including firewalls and load balancers The team has decided to enable telemetry and monitor CPU usage on all devices. The log collector has been configured with IP address 172.41.41.1. and the process is running on port 8021. Due to open-source software limitations, the log collector does not support encryption. Which two configurations should the Team include in the configuration template to achieve this Goal? (Choose two)
Options
- AConfigure protocol tcp no-tls under the subscription
- BConfigure encoding self-describing-gpb under destination-group
- CConfigure encoding tls-gpb under the sensor-group
- DConfigure protocol grpc no-tls under the destination-group
- EConfigure encoding gpb-tls-self under the subscription
Explanation
To provide detailed telemetry data from nearly 2000 devices without encryption, the team should configure gRPC as the protocol without TLS and use self-describing-gpb for efficient data encoding.
Common mistakes.
- A. TCP is a transport layer protocol, not an application layer protocol like gRPC or gNMI used for telemetry. Configuring protocol tcp no-tls is not a valid or standard option for telemetry subscriptions.
- C. The tls-gpb encoding specifies the use of Transport Layer Security (TLS) for encryption, which contradicts the requirement that the log collector does not support encryption.
- E. The gpb-tls-self encoding is not a standard or recognized encoding type for network telemetry subscriptions; standard options include gpb, self-describing-gpb, or json.
Concept tested. Network telemetry configuration (gRPC, encoding, no-TLS)
