An automation engineer is designing a Junos XML API workflow that uses the <get-config> operation. Which THREE parameters or filtering methods are valid when retrieving configuration data from a Junos device using NETCONF? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Specifying the source datastore (e.g., <source><running/></source>).
Valid filtering and parameter methods for <get-config> include specifying the target datastore source, applying subtree filtering, and using xpath-based filters under specific namespace conditions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using SQL queries enclosed in <sql-query> tags to extract table rows directly from the configuration database.
Why it's wrong here
SQL queries are not supported inside standard NETCONF <get-config> RPCs on Junos devices.
- ✓
Specifying the source datastore (e.g., <source><running/></source>).
Why this is correct
The <source> element is mandatory in <get-config> to specify which datastore to retrieve.
- ✓
Using subtree filtering inside the <filter> element to retrieve specific configuration nodes.
Why this is correct
Subtree filtering is a standard NETCONF filtering mechanism supported by Junos.
- ✓
Using XPath expressions within the <filter> element with type="xpath".
Why this is correct
Junos NETCONF server supports XPath filtering when type="xpath" is specified in the filter element.
- ✗
Using the <max-depth> attribute within the <get-config> tag to limit configuration tree traversal.
Why it's wrong here
<max-depth> is not a valid attribute for NETCONF <get-config> operations in Junos.
