Which YANG model type is IETF standardized and vendor-neutral?
  1. ietf-interfaces
  2. openconfig-interfaces
  3. Cisco-IOS-XE-native
  4. Cisco-NX-OS-device
✓ Correct Answer: A
IETF models (RFCs) are vendor-neutral standards. OpenConfig is industry consortium. Cisco-native is vendor-specific.
Q2
Which transport and port does NETCONF use on Cisco IOS XE?
  1. SSH over TCP 830
  2. HTTPS over TCP 443
  3. gRPC over TCP 57400
  4. Telnet over TCP 23
✓ Correct Answer: A
NETCONF (RFC 6241) uses SSH on TCP 830 by default on Cisco IOS XE.
Q3
Which RFC defines YANG tree diagram representation?
  1. RFC 8340
  2. RFC 6020
  3. RFC 7950
  4. RFC 8525
✓ Correct Answer: A
RFC 8340 defines YANG tree diagrams. 6020=YANG 1, 7950=YANG 1.1, 8525=YANG library.
Q4
In YANG, which statement defines a keyed list of entries?
  1. list
  2. leaf
  3. container
  4. leaf-list
✓ Correct Answer: A
A YANG 'list' defines multiple entries keyed by leaf(s). Container groups nodes (single). Leaf is single value. Leaf-list is unkeyed scalars.
Q5
Which HTTP header is required for RESTCONF with JSON?
  1. Content-Type: application/yang-data+json
  2. Content-Type: application/json
  3. Accept: text/xml
  4. Content-Type: text/html
✓ Correct Answer: A
RFC 8040 defines application/yang-data+json for RESTCONF JSON payloads.
Q6
What is a YANG module container statement used for?
  1. Groups related leaf nodes
  2. Defines a list of entries
  3. Defines a leaf value
  4. Defines a key
✓ Correct Answer: A
Container groups related leaf and container nodes into a hierarchy.
Q7
What is the difference between YANG leaf and leaf-list?
  1. leaf=one value; leaf-list=multiple unkeyed scalar values
  2. Same thing
  3. leaf-list is for keys
  4. leaf is for lists
✓ Correct Answer: A
leaf defines a single value. leaf-list defines multiple values without keys (like an array).
Q8
What is pyang used for?
  1. YANG model validation and tree diagram generation
  2. Python automation
  3. NETCONF client
  4. Ansible module
✓ Correct Answer: A
pyang validates YANG models and can generate tree diagrams with '-f tree' option per RFC 8340.
Q9
What are the three types of YANG models?
  1. IETF (standards), OpenConfig (consensus), Cisco-native (vendor)
  2. Public and private
  3. Standard and custom
  4. Basic and advanced
✓ Correct Answer: A
IETF=RFC standards, OpenConfig=multi-vendor industry, Cisco-native=full feature coverage.
Q10

  1. 830
  2. 22
  3. 443
  4. 57400

  2. Python IDE
  3. CLI
  4. Monitoring
✓ Correct Answer: A
YANG Suite constructs XML/JSON payloads from YANG models.
Q15

  1. leaf-list=unkeyed scalars; list=keyed entries
