- A
The size of the YANG data model.
Why wrong: Model size is determined by the standard and is not configurable in subscriptions; it affects the amount of data per update but is not a factor in configuring subscriptions.
- B
The collection protocol (gRPC vs gNMI vs native TCP).
The protocol determines capabilities like on-change reporting, encoding, and transport efficiency.
- C
Network bandwidth to the telemetry collector.
Bandwidth must be sufficient to handle the telemetry data rate to avoid congestion and loss.
- D
The sampling interval for periodic subscriptions.
The interval directly impacts data volume and the ability to capture events of interest.
- E
The encoding format (GPB, JSON, XML).
Why wrong: Encoding format affects parsing overhead and bandwidth but is secondary to the critical factors listed.
Quick Answer
The answer is the sampling interval for periodic subscriptions, network bandwidth to the collector, and the collection protocol. These three factors are critical because they directly determine the reliability, performance, and granularity of the telemetry data stream. The sampling interval controls how often data is pushed, directly impacting both the load on the network device and the resolution of the metrics, while insufficient bandwidth to the collector will cause dropped packets and data loss. The collection protocol, such as gRPC or TCP, dictates the transport mechanism and feature support, affecting everything from encryption to session management. On the Cisco SPCOR 350-501 exam, this question tests your ability to distinguish between configuration-critical elements and mere trade-offs; a common trap is confusing the YANG model size or encoding format as a subscription parameter. Remember the mnemonic “SBC” for Sampling, Bandwidth, and Collection protocol to lock in the three critical factors.
350-501 Automation and Assurance Practice Question
This 350-501 practice question tests your understanding of automation and assurance. 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 architect is designing a model-driven telemetry solution for a large SP network. Which three factors are critical to consider when configuring telemetry subscriptions? (Choose three.)
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
The collection protocol (gRPC vs gNMI vs native TCP).
Network bandwidth to the collector ensures the data can be transmitted without loss. The collection protocol affects performance and feature support. The sampling interval determines data granularity and load. The size of the YANG model is not a subscription configuration factor, and encoding format is a trade-off but not as critical as the others.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.
