The answer is that the 'encoding encode-kvgpb' line specifies the telemetry data should be encoded using Google Protocol Buffers (protobuf) in a key-value pair format. This is correct because KVGPB (Key-Value Google Protocol Buffers) is a compact binary encoding that reduces bandwidth and processing overhead compared to text-based formats like JSON or XML, making it ideal for high-frequency model-driven telemetry streams. On the ENCOR 350-401 exam, this tests your understanding of telemetry subscription parameters within Cisco IOS-XE and DNA Center fabrics, where efficient data transmission is critical for network monitoring. A common trap is confusing KVGPB with XML or JSON encoding, but remember that KVGPB is binary and protocol-buffer-based, not human-readable. For a memory tip, think "KVGPB = Key-Value Google Protocol Buffers — binary, compact, and fast," and note that it pairs naturally with the gRPC protocol shown in the receiver line.
CCNP Cisco DNA Center Practice Question
This 350-401 practice question tests your understanding of cisco dna center. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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:
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.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
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.
Related concept
Static NAT maps one inside address to one outside address.
✗
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.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 350-401 NAT questions on configuration and troubleshooting.
