Remove the route for 192.168.0.0/16 from interface b.
Enable DHCP on interface a but not on interface b.

Correct answer: A

An engineer configures Cisco Meeting Server as a conference resource for Cisco UCM. Cisco UCM has a secure SIP trunk to Cisco Meeting Server, but the server does not register to Cisco UCM. Which configuration resolves this issue?

Ensure that the SIP trunk from Cisco UCM to Cisco Meeting Server is a secure trunk using port 5061.
Add Cisco Meeting Server to the Cisco UCM SIP trunk with an IP address and not an FQDN.

Refer to the exhibit. Users report that they do not see a high-quality picture on the high-definition endpoints when they call into Cisco Meeting Server. An engineer must extract the SDP that is offered by Cisco Meeting Server from the SIP traces to troubleshoot. What is the cause of this issue?

Cisco Meeting Server is not configured for H.265 to support high-definition video calling.
The AES ciphers are not compatible with high-definition video calling.
The Content-Length value in the SDP does not support high-definition video calling.
The SIP call bandwidth is not at a value that supports high-definition video calling.

Refer to the exhibit. When a user dials 8001 to connect to a space that is hosted on Cisco Meeting Server, the user is prompted for a pin. The prompt says the user should press # to connect to a meeting without a pin, but guests and hosts must enter a pin before connecting to the meeting.

Which configuration change resolves this issue?

The secret value must be changed to be solely numeric instead of alpha-numeric.
The passcode must be changed to be longer than four digits.
All access methods that are associated with the space must be changed to include a pin.
A callLegProfile must be created and associated with the space so that pins are not optional.

An administrator wants to automatically schedule conferences with a cluster of Cisco Meeting Server devices that are managed with Cisco TMS.

How should Cisco TMS be configured to accomplish this goal?

After the Cisco Meeting Server cluster is added, the Cisco TMS should failover an active conference to a different Cisco Meeting Server.
After the first Cisco Meeting Server is added, all servers in the cluster should automatically be detected.
When the first Cisco Meeting Server is added, the system name should automatically be detected.
After the Cisco Meeting Server cluster is added, the primary Cisco Meeting Server should automatically failover to another cluster member.

Correct answer: D

An engineer must configure Cisco Meeting Server integration to Cisco UCM. Which DNS A record must be configured to accomplish this goal?

In the Cisco TMS GUI, a Cisco UCM registered system shows these error details:

Provisioning mode is set to Cisco UCM for this system.
The system cannot be refreshed or scheduled.
To manage this system as a Cisco TMS system, the provisioning mode needs to be changed to Cisco TMS.
To add the system as Cisco UCM managed system, it must be added through the Cisco UCM that is provisioning the system.

What should be done to resolve this error?

Purge the system in Cisco TMS and add the system back directly to Cisco TMS using “Add by IP Address”.
Restart Microsoft IIS on the Windows server that hosts Cisco TMS and perform a “Force Refresh” on the system.
Delete the system and add the system back with the “Add from Cisco UCM or Cisco TMS” option.
Update the credentials for the system in Cisco TMS.

Correct answer: C

Refer to the exhibit. An administrator configures Expressway-C to act as a proxy for a Cisco Meeting Server web app.

matching authentication combinations on the web app and Expressway-C
Common Name of “_cms-web._tls.join.darmckin.local” on the certificate in use
