Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
They automatically compile Python scripts into binary executable files for Junos.
Why it's wrong here
Incorrect. Virtual environments do not compile binaries.
- ✓
They allow installing specific versions of PyEZ, lxml, and Jinja2 independently of system Python.
Why this is correct
Correct. Local package management gives version control.
- ✗
They remove the need to install SSH clients on the local machine.
Why it's wrong here
Incorrect. NETCONF/SSH transport still depends on underlying libraries.
- ✗
They enable direct root-level execution of Junos CLI commands on physical routers.
Why it's wrong here
Incorrect. Virtual environments run on the local automation host, not the router.
- ✓
They isolate Python package dependencies for specific projects, preventing version conflicts.
Why this is correct
Correct. Isolation prevents dependency clashes across projects.
