ENSLD 5.0 Automation (10%)¶
Automation on ENSLD is a choose and justify domain, not a coding domain. You will not write Python or build payloads. You will be given requirements and asked which YANG model set, which protocol, which telemetry style or which cloud connection fits, and what the trade-off is. Because ENCOR already teaches the mechanics, these pages link back to it and spend their words on design reasoning.
| Objective | Verb | Page |
|---|---|---|
| 5.1 Choose the YANG data model set (IETF, OpenConfig, Cisco native) | Choose | YANG model sets, NETCONF and RESTCONF |
| 5.2 Differentiate NETCONF and RESTCONF | Differentiate | YANG model sets, NETCONF and RESTCONF |
| 5.3 Impact of model-driven telemetry on the network | Explain | Model-driven telemetry |
| 5.4 gRPC and gNMI telemetry: dial-in and dial-out, periodic and on-change | Choose | Model-driven telemetry |
| 5.5 Cloud connectivity: direct connect, cloud on-ramp, MPLS direct connect, WAN integration | Choose | Cloud connectivity and service models |
| 5.6 Cloud service models (SaaS, PaaS, IaaS) in private, public and hybrid deployments | Match | Cloud connectivity and service models |
Prerequisites from ENCOR¶
- YANG data modeling: how models are written and the model families
- NETCONF and RESTCONF: operations, datastores, methods and response codes
- Catalyst SD-WAN: the overlay that Cloud OnRamp extends
- Catalyst Center: where telemetry feeds Assurance
How to study this domain¶
- Learn the comparison tables until you can reproduce them. Almost every question here is "which one, given this requirement".
- For each page, do the design exercise before you open the model answer. Write down your choice and the alternative you rejected, then compare.
- Practise the distinctions the exam traps call out: model versus protocol versus encoding, dial-in versus dial-out, direct connect versus cloud on-ramp, service model versus deployment model.
Time budget: See the study plan. Allow about 3 to 4 hours for the three pages and the quiz, since this is the smallest domain.
When you finish, take the Automation practice questions. Aim for 80% or better before moving on.
