350-401 Practice Question: Is configuring model-driven telemetry on a Cisco…
A network engineer is configuring model-driven telemetry on a Cisco IOS-XE device that is part of a DNA Center managed fabric. The telemetry subscription configuration is:
telemetry ietf subscription 101 encoding encode-kvgpb filter xpath /process-cpu-ios-xe-oper:cpu-usage/cpu-utilization stream yang-push update-policy periodic 500 receiver ip address 10.10.10.10 port 5555 protocol grpc-tcp
What is the purpose of the 'encoding encode-kvgpb' line?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It specifies that the data should be encoded using Google Protocol Buffers (protobuf) with key-value pairs.
The 'encoding encode-kvgpb' specifies that the telemetry data should be encoded using KVGPB (Key-Value Google Protocol Buffers), which is a compact binary encoding used for efficient data transmission.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It sets the encoding to JSON format for the telemetry data.
Why it's wrong here
KVGPB is not JSON; it is a binary encoding.
- ✓
It specifies that the data should be encoded using Google Protocol Buffers (protobuf) with key-value pairs.
Why this is correct
Correct. KVGPB is a protobuf-based encoding optimized for telemetry.
- ✗
It enables encryption of the telemetry data.
Why it's wrong here
Encoding is not encryption; it is a serialization format.
- ✗
It defines the compression algorithm for the telemetry stream.
Why it's wrong here
Encoding does not imply compression.
