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 allow automation scripts to parse device output reliably without relying on brittle regular expressions.
Why this is correct
Correct. Structured data eliminates the need for complex, error-prone regex parsing of CLI text.
- ✗
Structured data formats take up less memory on the Junos Routing Engine hard drive.
Why it's wrong here
File size is not the primary driver; programmability and parsing reliability are.
- ✗
They eliminate the need to authenticate when connecting via NETCONF or gRPC.
Why it's wrong here
Authentication is still strictly required regardless of data format.
- ✗
They automatically convert all IPv4 addresses to IPv6 format.
Why it's wrong here
Structured formats do not alter IP address versions.
