How should I use these Scenario practice questions?

Read each scenario carefully and choose your answer before revealing the explanation. Then check why your choice was right or wrong. Repeat until the reasoning feels automatic.

Can I practise just Scenario questions in a focused session?

Yes — use the session launcher on this page to start a 10-, 20-, 30- or 50-question session drawn entirely from the Scenario domain.

Scenario practice questions

Practise Cisco Implementing Cisco Collaboration Core Technologies (CLCOR, 350-801, v2.0 blueprint, CCNP Collaboration) (CLCOR) Scenario practice questions — original exam-style scenarios with answer choices, explanations, and analysis of common mistakes.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Scenario

Scenario questions test whether you can apply the concept in context, not just recognise a definition.

How the topic appears in realistic exam-style scenarios.

Which detail in the question changes the correct answer.

How to eliminate plausible but wrong options.

How to connect the question back to the wider exam objective.

Watch out for

Common Scenario exam traps

▸Answering from memory before reading the full scenario.
▸Missing a constraint such as cost, availability, security, scope or command context.
▸Choosing a broad answer when the question asks for the most specific fix.
▸Ignoring why the wrong options are tempting.

What is the primary function of the CUBE in a SIP trunking scenario?

Trap 1: Call routing for internal phones

That is the primary role of CUCM.

Trap 2: Voice messaging storage

That is the function of Unity Connection.

Trap 3: DHCP Server functionality

CUBE is not typically used as a DHCP server.

You are troubleshooting a scenario where internal calls between two offices are using the G.711 codec, but you want them to use G.729 to save bandwidth. Where should you change the codec setting?

Trap 1: Device > Device Settings > Common Device Configuration

Common Device Configuration manages device features like softkeys, not codec negotiation.

Trap 2: System > Device Pool

Device pools assign regions, but do not define the codec matrix itself.

Trap 3: System > Location

Locations are for CAC, not codec negotiation.

A
Device > Device Settings > Common Device Configuration
Why wrong: Common Device Configuration manages device features like softkeys, not codec negotiation.
B
System > Region Information > Region
The Region matrix allows you to define the maximum audio bit rate between specific regions.
C
System > Device Pool
Why wrong: Device pools assign regions, but do not define the codec matrix itself.
D
System > Location
Why wrong: Locations are for CAC, not codec negotiation.

You are troubleshooting a scenario where internal calls between two sites are failing. The call fails immediately when dialed. What is the most effective way to verify that the Calling Search Space (CSS) has access to the destination partition?

Trap 1: Check the 'Route Filter' list.

Route filters match digits, not CSS reachability.

Trap 2: Use the 'Route Pattern' report in Cisco Unified Reporting.

This report does not simulate a specific call.

Trap 3: Reset the SIP trunk.

Resetting the trunk does not fix partition access issues.

A
Check the 'Route Filter' list.
Why wrong: Route filters match digits, not CSS reachability.
B
Use the 'Route Pattern' report in Cisco Unified Reporting.
Why wrong: This report does not simulate a specific call.
C
Reset the SIP trunk.
Why wrong: Resetting the trunk does not fix partition access issues.
D
Use the Dialed Number Analyzer (DNA) tool.
DNA allows you to simulate a call from a specific device to see if the partition is reachable.

Question 4mediummultiple choice

You are configuring a hybrid calling scenario. Which component must be configured to enable inter-cluster dialing between on-premises CUCM and Webex Calling?

Trap 1: An H.323 Gatekeeper.

H.323 is not supported for this integration.

Trap 2: A secondary Webex app.

The app is a client, not a routing component.

Trap 3: A PSTN Gateway.

A PSTN gateway is for external calls, not internal inter-cluster calls.

Study all Scenario common traps →

A
A SIP Trunk between CUCM and the CUBE.
The SIP trunk facilitates the routing of calls between the local environment and the cloud.
B
An H.323 Gatekeeper.
Why wrong: H.323 is not supported for this integration.
C
A secondary Webex app.
Why wrong: The app is a client, not a routing component.
D
A PSTN Gateway.
Why wrong: A PSTN gateway is for external calls, not internal inter-cluster calls.

Question 5mediummultiple choice

You are troubleshooting a scenario where video quality is degrading during periods of high data utilization. You identify that video traffic is being dropped in the network. What is the most likely cause if you are using CBWFQ?

Trap 1: The voice traffic is taking up all bandwidth

Voice typically uses a small, defined bandwidth percentage in LLQ.

Trap 2: The router's CPU is overloaded

CPU load affects control plane performance, not media flow prioritization.

Trap 3: The interface is configured for full-duplex

Full-duplex is standard for modern networks and does not cause drops.

Study all Scenario common traps →

A
Video is not being correctly classified into the priority queue
If not correctly classified, video traffic competes with data traffic in the default queue.
B
The voice traffic is taking up all bandwidth
Why wrong: Voice typically uses a small, defined bandwidth percentage in LLQ.
C
The router's CPU is overloaded
Why wrong: CPU load affects control plane performance, not media flow prioritization.
D
The interface is configured for full-duplex
Why wrong: Full-duplex is standard for modern networks and does not cause drops.

You are troubleshooting a scenario where G.711 is being used instead of the expected Opus codec between two endpoints in the same region. What is the most likely cause in the CUCM configuration?

Trap 1: Phone NTP settings

NTP is for time synchronization.

Trap 2: SIP Trunk Security Profile mismatch

This affects signaling security, not codec selection.

Trap 3: Location-based bandwidth limit

This limits total calls, not individual codec types.

Study all Scenario common traps →

A
Audio Codec Preference List
The codec preference list dictates the order and availability of codecs.
B
Phone NTP settings
Why wrong: NTP is for time synchronization.
C
SIP Trunk Security Profile mismatch
Why wrong: This affects signaling security, not codec selection.
D
Location-based bandwidth limit
Why wrong: This limits total calls, not individual codec types.

You are troubleshooting a scenario where users in a Hybrid Calendar deployment cannot see free/busy information for their on-premises Exchange resources. Which tool in Control Hub provides the most granular logs for the Hybrid Calendar service?

Trap 1: Exchange EWS Connectivity Test

This is a general tool, not specific to Webex hybrid logs.

Trap 2: Control Hub Analytics Dashboard

This shows trends, not specific service logs.

Trap 3: Webex Calling Provisioning Report

This is for user provisioning, not calendar integration.

A
Hybrid Service Connector Status Logs
Connector logs are the primary diagnostic tool for hybrid services.
B

Trap 1: SIP Trunk Security Profile

This is for security settings.

Trap 2: Route Pattern

Route patterns do not control SIP headers.

Trap 3: Device Pool

Device pools do not manage SIP headers.

Frequently asked questions

What does the CLCOR exam test about Scenario?: Scenario questions test whether you can apply the concept in context, not just recognise a definition.
How should I use these practice questions?: Select your answer before revealing the explanation. Then read why each option is right or wrong — this active recall approach builds retention far faster than re-reading notes.
Can I practise just Scenario questions in a focused session?: Yes — the session launcher on this page draws every question from the Scenario domain. Use a 10-question session first to gauge your baseline, then move to 20 or 30 once the weak spots are clear.
Where can I practise other CLCOR topics?: Use the topic links above to move to related areas, or go back to the CLCOR question bank to see all topics.
Are these real exam questions or dumps?: These are original practice questions written to test the same concepts the CLCOR exam covers. They are not copied from any real exam or dump site.
