TLS certificates between publisher nodes in all clusters.

Call Manager certificates between publisher nodes in all clusters.

Tomcat certificates between publisher nodes in all clusters.

2. An engineer is analyzing an issue about system connection under Cisco TMS connection, where endpoints handled by TMS automatically change from reachable on LAN to behind the firewall status.

Which protocol does the network engineer need to troubleshoot the network between managed device Cisco TMS?

SDP

XMPP

FTP

HTTP

3. Refer to the exhibit.

An engineer configured CCD between a Cisco Unified Communications Manager (CUCM) cluster and Cisco Unified Communications Manager Express (CME). When the CUCM agents try to dial a CME extension on the range 7XXX, they receive a busy signal as soon as the 7 is dialed.

What can be done to resolve this issue?

Set the CUCM CCD Requesting Service PSTN prefix to 9 instead of\+

Set the CME profile dn-block type to extension instead of global

Set the CUCM Hosted DN Pattern PSTN Failover Strip Digits field to 1 instead of 0

Set the CME subscribe callcontrol to instance instead of wildcarded

4. Which two types of call causes the user to hear the reorder tone? (Choose two.)

call to a number that is working but is unlisted

restricted call

call using a non-Cisco phone

call to a number that has been blocked

unrestricted call

5. Replication is failing between the Cisco Unified Communications Manager Publisher and Subscriber servers.

In which two ways can you verify the database replication status? (Choose two.)

TRACERT

CLI

APIC-EM

PING

RTMT

6. An engineer is investigating voice quality degradation on calls passing through a particular SIP gateway. To gather the necessary information, sample traffic captures are taken.

Which information in the capture reveals the problem?

destination port

version

ToS bits

MTU

7. Which Cisco Unified Communications Manager troubleshooting tool can be used to look at detailed specific events, such as dial plan digit analysis, as they are happening?

RTMT real-time trace

Cisco Unified Dialed Number Analyzer

syslog output

RTMT performance log viewer

8. An engineer is troubleshooting an issue where aliases that contain an identity “@abc.com” are unable to register with an endpoint due to an entry in the registration restriction configuration in Expressway-E.

Where is the alias being blocked in Expressway-E?

regex list

hunt list

black list

allow list

9. Which two statements about Cisco Unified CM location bandwidth deduction are true? (Choose two.)

If a call uses G.711, Cisco Unified Communications Manager subtracts 64k.

If a call uses G.711, Cisco Unified Communications Manager subtracts 80k.

If a call uses G.723, Cisco Unified Communications Manager subtracts 16k.

If a call uses G.729, Cisco Unified Communications Manager subtracts 16k.

If a call uses G.729, Cisco Unified Communications Manager subtracts 24k.

10. Which command is used to check if an MGCP gateway is currently registered with Cisco CallManager?
