The answer is operational. This state is confirmed in the show vpc output when the vPC domain ID is set, the peer-keepalive link shows as Active, the peer-link status is up, and the vPC role is primary, with the operational status field explicitly reading operational, meaning all consistency checks have passed and the domain is fully functional. On the Cisco DCCOR 350-601 exam, this question tests your ability to quickly interpret the show vpc command output, a core skill for verifying high-availability data center designs. A common trap is confusing the peer-link status with the overall domain operational status—the peer-link can be up while the domain is still non-operational if consistency checks fail. Remember the mnemonic: DROP—Domain ID, Role, Operational status, Peer-link—to scan the four critical fields that must all be correct for a truly operational domain.
350-601 Network Practice Question
This 350-601 practice question tests your understanding of network. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Exhibit
vPC domain id : 1
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency : success
vPC role : primary
Number of vPCs configured : 5
Refer to the exhibit. What is the current state of the VPC domain?
vPC domain id : 1
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency : success
vPC role : primary
Number of vPCs configured : 5
A
VPC domain not configured
Why wrong: Domain ID is present, so it is configured.
B
Peer-link down
Why wrong: Peer adjacency is formed, so peer-link is up.

Correct answer & explanation
✓
Operational
The exhibit shows the output of 'show vpc' with the vPC domain ID set to 100, the peer-keepalive link status as 'Active', and the peer-link status as 'up'. The vPC role is 'primary' and the operational status is listed as 'operational', which indicates that the vPC domain is fully functional and all consistency checks have passed. Therefore, the current state is operational.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
VPC domain not configured
Why it's wrong here
Domain ID is present, so it is configured.
✗
Peer-link down
Why it's wrong here
Peer adjacency is formed, so peer-link is up.
✗
Consistency check failed
Why it's wrong here
The consistency check shows 'success'.
✓
Operational
Why this is correct
All fields indicate normal operation.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between the peer-link being 'up' and the vPC domain being 'operational', where candidates may incorrectly assume a peer-link failure when the domain is actually operational, or confuse a consistency check failure with a peer-link issue.
Trap categories for this question
Command / output trap
The consistency check shows 'success'.
Detailed technical explanation
How to think about this question
The vPC operational status is determined after both the peer-keepalive link (using UDP port 3200) and the peer-link (using a dedicated LACP-based port-channel) are established and the vPC consistency check (type-1 and type-2 parameters) passes. In a real-world scenario, if the consistency check fails, the vPC will not become operational and the 'show vpc' output will display 'failed' or 'suspended' for the vPC, often with a specific reason code.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-601 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
