Juniper Networks Certified Associate, DevOps

Juniper · beginner · 90 minutes

In developmentThis course is still being brought to our full standard. The questions and notes are usable, but they have not yet been checked line by line against the vendor’s own training.

Treating the network as code: the case for automation over slow, inconsistent manual change, the XML, JSON and YAML data formats representing the same structured data, APIs over CLI scripting with NETCONF exchanging XML over SSH and YANG modelling device data; then Python and PyEZ driving devices programmatically, agentless declarative Ansible with idempotent playbooks describing desired state, version control making change reviewable and reversible, and a CI/CD pipeline that validates, tests and deploys configuration automatically on commit.

Automation concepts, data formats and NETCONF	Not published
Tools, PyEZ, Ansible and CI/CD	Not published

Two sample questions

Two of the 196, with the answer and the explanation.

1. Why is starting automation with read-only or reporting tasks a prudent adoption path?

Value and confidence without risking device state — correct
Read-only tasks run faster than writes
Reporting needs no version control
Read tasks require no credentials

Why: Read-only tasks such as gathering state deliver value and build the team confidence and skills without the risk of changing device configuration, which is a safe way to begin adopting automation.

2. Why represent config as data?

To confuse the tools
To slow down change
So tools can check it — correct
To hide the config

Why: Representing config as data lets tools generate, validate and diff it.
