Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The client and server exchange <hello> messages to negotiate supported capabilities.
Why this is correct
Capability negotiation via <hello> messages is a mandatory first step in NETCONF.
- ✗
The client sends an immediate <commit> RPC to initialize the session.
Why it's wrong here
Commits are only sent when configuration changes are made.
- ✗
The routing engine reloads its control plane daemons.
Why it's wrong here
Daemons do not reload upon NETCONF connection.
- ✓
The client authenticates via SSH credentials before the NETCONF subsystem initializes.
Why this is correct
SSH authentication precedes the NETCONF session start.
- ✗
The Junos device automatically locks the running configuration datastore.
Why it's wrong here
Locks are never established automatically upon connection.
