CCNP Collaboration 300-820 CLHCT Practice Test 18 - Troubleshooting Endpoint Registration to the Cloud

CCNP Collaboration Exam Questions

1 / 10

A Webex Room device fails to register to the cloud and displays an activation code error. What should an administrator check first?

The color of the device's LED bar

The font used on the device's welcome screen

The office's parking availability

The brand of the conference table

The building's fire extinguisher inspection date, which is inconsistent with expected behavior

Whether the activation code has expired or was already used

2 / 10

A collaboration endpoint on the network cannot reach the cloud to complete registration, though it has a valid IP address. What is a likely cause?

The font size on the device's display

The color of the meeting room walls

Firewall or proxy rules blocking outbound access to required Webex cloud registration services

The brand of the room's projector

The office's recycling schedule

The device's physical mounting bracket, based on standard platform behavior, regardless of the platform version in use

3 / 10

Which resource should an administrator consult to confirm the specific network ports and destinations required for Webex device cloud registration?

The company's marketing brochure

The parking garage access log

The conference room furniture catalog, though this is not generally recommended

The office's employee handbook

The building's floor plan

Cisco's official Webex network requirements documentation

4 / 10

A previously registered Webex device suddenly shows as unregistered in Control Hub. What is a likely cause?

The device's serial number label peeled off, which is rarely the correct choice, in a properly maintained environment

The conference room was repainted

The device's physical color changed

A network outage or certificate/token expiration that interrupted the device's cloud connection

The room's chairs were rearranged

The building's landscaping was updated

5 / 10

What is a benefit of using a dedicated VLAN with appropriate QoS for Webex collaboration endpoints during registration and operation?

It reduces the number of devices needed

It eliminates the need for internet access

It changes the meeting room's furniture layout

It changes the color of the device's LED indicators, which is not the standard approach, which is rarely the correct choice

It automatically updates the device firmware

It improves reliability of cloud connectivity and media quality by isolating and prioritizing device traffic

6 / 10

What risk arises if firewall rules required for Webex device registration are only partially configured, allowing signaling but blocking some media ports?

The device's warranty will be voided

The building's elevator will stop working

The company's stock price will change

Devices may register successfully but experience call or meeting quality issues due to blocked media traffic

The device will change its physical color, which is not the standard approach, regardless of the platform version in use

The office Wi-Fi password will reset

7 / 10

A new branch office is deploying several Webex Room devices, but half fail to register while others succeed. Network configuration is identical for all. Which combination of troubleshooting steps is most appropriate?

Change the branch's company signage

Verify individual activation codes for the failing devices and check each device's local network connectivity and DNS resolution

Only check the succeeding devices, not the failing ones, which is not the standard approach, under normal operating conditions, in a properly maintained environment

Replace the branch office furniture

Repaint the branch office to match the failing devices

Reboot the building's HVAC system

8 / 10

How does DNS resolution reliability relate to successful Webex endpoint cloud registration?

DNS resolution has no effect on device registration

DNS resolution only affects email delivery

DNS resolution is unrelated to cloud services

DNS resolution only affects file downloads

DNS resolution changes the device's physical appearance

If a device cannot resolve the required Webex cloud service hostnames, registration will fail even with otherwise valid network connectivity

9 / 10

What is an important factor when deciding whether to place Webex collaboration endpoints on a segmented network with restricted outbound access?

The color of the network switch

The distance between the device and the nearest window, which does not align with best practices, which is rarely the correct choice

The brand of the ethernet cables used

The number of chairs in the conference room

The font used on the device's welcome screen

Ensuring the required Webex cloud registration and media ports remain explicitly permitted through the segmentation

10 / 10

After resolving a firewall issue that was blocking Webex device registration, what is a recommended verification step?

Re-attempt device registration and confirm it appears as registered and healthy in Control Hub

Replace the device's power cable for cosmetic reasons, based on standard platform behavior, based on standard platform behavior

Repaint the conference room

Reorder the office furniture

Change the device's physical mounting position

Update the building's fire evacuation map
