Question 72 of 2,015

Cisco DNA Center →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is a UUID string such as '123e4567-e89b-12d3-a456-426614174000'. This output occurs because the Python script queries the DNA Center API endpoint for all sites, then iterates through the response to find the building named 'Building-A' and prints its unique site ID. The Cisco DNA Center API assigns a globally unique identifier (UUID) to every site object—whether area, building, or floor—so a successful creation returns this string rather than a simple integer or a success message. On the ENCOR 350-401 exam, this tests your understanding of REST API responses and how the DNA Center models site hierarchy; a common trap is expecting a boolean or status code instead of the actual UUID. Remember that in DNA Center, every site is a resource with a UUID, so when verifying via API, you are looking for that specific identifier, not a confirmation flag. A helpful memory tip: "UUID for unique ID" ties the concept of site verification to the universally unique identifier output.

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 engineer is using the Cisco DNA Center GUI to create a new site hierarchy. They add a building under an existing area. After saving, they run a Python script to verify the site via API:

import requests

url = "https://dna-center.local/dna/intent/api/v1/site" headers = {"X-Auth-Token": "token"} response = requests.get(url, headers=headers, verify=False) sites = response.json()['response']

for site in sites:
    if site['name'] == 'Building-A':
        print(site['id'])

What is the output if the building was created successfully?

A
A UUID string such as '123e4567-e89b-12d3-a456-426614174000'
Correct. The API returns a UUID for each site, and the script prints it.
B
The script will print 'Building-A'
Why wrong: The script prints site['id'], not site['name'].
C
The script will print the entire site dictionary
Why wrong: It only prints the id field.
D
The script will raise an error because the API returns paginated results
Why wrong: The script assumes all sites are returned in one response, which may be true for small hierarchies, but the output would still be the ID if found.

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

✓

A UUID string such as '123e4567-e89b-12d3-a456-426614174000'

The script prints the site ID of the building if it exists. The output will be a string representing the UUID of the building.

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.

✓
A UUID string such as '123e4567-e89b-12d3-a456-426614174000'
Why this is correct
Correct. The API returns a UUID for each site, and the script prints it.
Related concept
OSPF neighbours must agree on key parameters.
✗
The script will print 'Building-A'
Why it's wrong here
The script prints site['id'], not site['name'].
✗
The script will print the entire site dictionary
Why it's wrong here
It only prints the id field.
✗
The script will raise an error because the API returns paginated results
Why it's wrong here
The script assumes all sites are returned in one response, which may be true for small hierarchies, but the output would still be the ID if found.

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.

Trap categories for this question

Command / output trap
The script assumes all sites are returned in one response, which may be true for small hierarchies, but the output would still be the ID if found.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

What to study next

Got this wrong? Here's your next step.

Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related 350-401 OSPF questions on adjacency and route selection.
