The answer is the `parentName` parameter specifies the name of the building's parent in the hierarchy, such as an area or global site. This is correct because Cisco DNA Center organizes network sites into a strict hierarchical structure—global, area, building, and floor—and the `parentName` field is required to place a new building under its logical parent (e.g., "Area-1") so the API can correctly nest the site within the existing topology. On the ENCOR 350-401 exam, this tests your understanding of how automation tools like Ansible interact with DNA Center’s site management, often appearing in questions about playbook parameters or hierarchy validation. A common trap is confusing `parentName` with `name` or omitting it entirely, which causes the API to reject the request. Remember the memory tip: "ParentName places the piece—without it, your building has no foundation."
350-401 Cisco DNA Center Practice Question
This 350-401 practice question tests your understanding of cisco dna center. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An Ansible playbook uses the cisco.dnac.site module to create a new building site. The playbook is:
- name: Create building site
cisco.dnac.site:
host: "{{ dnac_host }}"
username: "{{ dnac_username }}"
password: "{{ dnac_password }}"
validate_certs: no
state: present
site:
name: Building-B
type: building
parentName: Area-1
address: "123 Main St"
latitude: 37.7749
longitude: -122.4194
register: result
What is the purpose of the 'parentName' parameter?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It specifies the name of the building's parent in the hierarchy, such as an area or global site.
The 'parentName' parameter specifies the name of the parent site (area or global) under which the building is created. This is necessary for building the site hierarchy.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
It specifies the name of the building's parent in the hierarchy, such as an area or global site.
Why this is correct
Correct. The parentName defines where in the site hierarchy the building is placed.
It sets the name of the network profile associated with the building.
Why it's wrong here
Network profiles are separate from site hierarchy.
✗
It is used to specify the building's primary IP address.
Why it's wrong here
The building itself does not have an IP address.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
OSPF neighbours must agree on key parameters.
Router ID selection can affect neighbour relationships and LSDB output.
OSPF cost influences the preferred path.
A route can appear in OSPF information but not become the installed route.
TExam Day Tips
→Check area mismatch first when OSPF adjacency fails.
→Review passive interfaces when a network is advertised but no neighbour forms.
→Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-401 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
