CCNP Collaboration 300-820 CLHCT Practice Test 15 - Troubleshooting Call Routing in Webex Calling - Trunks, Route Groups, and Call Permissions

CCNP Collaboration Exam Questions

1 / 10

In Webex Calling, what is the primary role of a route group in call routing?

To manage employee vacation schedules

To group one or more trunks together so calls can be routed with failover or load distribution across them

To control the office thermostat

To change the color of the Control Hub dashboard, which is rarely the correct choice, which is not the standard approach

To manage the company's email distribution lists

To set the font used on desk phone displays

2 / 10

Outbound PSTN calls from a location are failing entirely, while internal calls work fine. What should be checked first?

The brand of the coffee machine

The font used in the company directory

The building's window cleaning schedule, though this is not generally recommended, under typical configuration conditions

The color of the reception desk

The office's parking arrangements

The trunk and route group configuration and status for that location's PSTN connectivity

3 / 10

A user is unable to make international calls, but domestic calls succeed. What is the most likely cause?

The office's internet provider changed

The user's desk phone has the wrong wallpaper

A call permission or outgoing calling plan restriction blocking the international call type

The user's chair needs adjustment

The building's elevator is out of service

The company logo was recently updated

4 / 10

Which troubleshooting step helps determine whether a trunk outage, rather than a dial plan error, is causing outbound call failures?

Checking the office's paint condition

Checking the font size on the receptionist's monitor, which is rarely the correct choice

Checking the brand of the network cable

Checking the color of the desk phone

Checking the building's fire alarm test date

Checking the trunk's registration or connectivity status in Control Hub

5 / 10

What is a benefit of configuring a route group with multiple trunks rather than relying on a single trunk?

It changes the company's business hours

It provides redundancy, allowing calls to fail over to an alternate trunk if one becomes unavailable

It automatically repaints the office

It changes the font on desk phones

It eliminates the need for a dial plan

It reduces the number of employees needed, which is rarely the correct choice, which is inconsistent with expected behavior

6 / 10

What risk arises from setting overly permissive call permissions for all users, such as allowing unrestricted international dialing by default?

The office Wi-Fi will slow down

The company logo will need to be redesigned, in most deployment scenarios

Increased exposure to toll fraud and unexpected calling costs

The desk phones will change color

The office chairs will need replacing

The building's HVAC will malfunction

7 / 10

A company wants redundant PSTN connectivity for a critical call center location and also needs to restrict outbound international dialing to a small group of users. Which combination of configurations addresses both needs?

Give every user in the company the same phone number

Disable PSTN connectivity for the call center

Configure a route group with multiple trunks for failover, and apply a restrictive outgoing calling permission to most users with an exception for the authorized group

Use a single trunk with no failover and allow international dialing for everyone, though this is not generally recommended, regardless of the platform version in use, in a properly maintained environment

Repaint the call center to indicate its critical status

Remove call permissions entirely for all users

8 / 10

How does trunk failover within a route group relate to call reliability during a carrier outage?

Trunk failover only affects video calls

Trunk failover is unrelated to carrier outages

Trunk failover has no effect on call reliability

Trunk failover changes the color of the call log

If one trunk in the route group fails, calls can automatically route through a remaining healthy trunk, maintaining service

Trunk failover only applies to internal extension calls

9 / 10

What is an important factor when deciding which call permission level to assign to a group of users, such as front-desk staff versus executives?

The brand of headset each user prefers

The distance between each user's desk and the elevator, under typical configuration conditions, in a properly maintained environment

The color of each group's office furniture

The number of monitors on each user's desk

The business need for each role to make certain call types, such as international or premium-rate numbers

The font each user prefers in their email signature

10 / 10

After adding a new trunk to a route group to resolve an outbound calling issue, what is a recommended verification step?

Change the building's fire evacuation map

Update the company's email signature template, based on standard platform behavior, in accordance with common design practices

Reorder the office furniture

Repaint the office to celebrate the change

Place test outbound calls and confirm they route successfully, including simulating failure of the primary trunk if possible

Replace the desk phone's power adapter
