Which two statements about Expressway media traversal are true? (Choose two.)
- A . Expressway Control is the traversal server installed in the DMZ.
- B . The Expressway Edge must be put in a firewall DMZ segment.
- C . Cisco Unified Communications Manager zone can be either traversal server or client.
- D . The Unified Communications traversal zone can be used for Mobile and Remote Access.
- E . Both Expressway Edge interfaces can be NATed.
Refer to the exhibit.
Calls to locally registered endpoints are failing. At present, there are two endpoints registered locally to this Expressway. An H.323 endpoint with an alias of `EndpointA` is registered, and a SIP endpoint with an alias of `[email protected]` is also registered.
How is this issue resolved?
- A . The dialplan must be redesigned to use the transforms to convert the alias into SIP URI format and then use separate search rules for each format that needs to be dialed within the local zone.
- B . The calls are failing because there are insufficient licenses. Additional licenses must be installed for the Expressway to route these calls.
- C . The current search rule does not match the call, so the search rule must be modified to include a SIP Variant of “Standards-Based”
- D . Calling parties are placing calls with the wrong domain. End-users must be instructed not to use the pod1.local domain as that is owned by the local system. Calls to any other domain would work.
What is a requirement when configuring the Cisco Webex Hybrid Message account for accessing the API of the Cisco UCM IM and Presence Service?
- A . Add a new end-user with the “Standard AXL API Access” role
- B . Use an application user with only the “Standard CTI Allow Control of All Devices” role
- C . Use an application user not the main administrator account with the “Standard AXL API Access” role
- D . Use the main administrator account if it includes the “Standard AXL API Access” role

Cisco Unified Communications Manager routes the call via the Webex Meetings route list and route group to the Video Mesh cluster Node#1 in the Video Mesh cluster is hosting the meeting and has reached full capacity, but other nodes in the cluster still have spare capacity.
What happens to the participant’s call?
- A . Another node in the cluster is used and an intra-cluster cascade between the two Video Mesh nodes is formed.
- B . The call is queued.
- C . The call fails.
- D . Another node in the cluster is used and an intra-cluster cascade between Webex and the new Video Mesh node is formed.
Which statement about the Cisco Webex hybrid service is true?
- A . Expressway Connector is required for an on-premises Exchange server.
- B . Hybrid Message service works only with Jabber cloud deployment.
- C . Directory Connector is required for Azure AD.
- D . Directory Connector must be deployed for OBTP to work with on-premises video devices.
An employee has recently left an organization and a manager suspects that this employee may have made changes to the system that no one is aware of. Mobile and Remote Access registration is not working. Internal communications appear to be working, but no external system is able to register or call anywhere. While investigating this problem, it is discovered that no internal systems are able to call externally either.
What is the TraversalZone missing that is causing this issue?
- A . SIP trunk to the DefaultZone
- B . route pattern to the DefaultZone
- C . link to the DefaultZone
- D . pipe to the DefaultZone
Refer to the exhibit
Showing logs from the Expressway-C, a copy of the Expressway-E certificate, and the UC traversal zone configuration for the Expressway-C.
An office administrator is deploying mobile and remote access and sees an issue with the UC traversal zone. The zone is showing `TLS negotiation failure`.
What is causing this issue?
- A . The Expressway-E certificate includes the Expressway-C FQDN as a SAN entry
- B . The Expressway-C is missing the FQDN of Cisco UCM in the Common Name of its certificate
- C . In the UC Traversal Zone on the Expressway-C, the peer address is set to the IP of the Expressway-E, which is not a SAN entry in the Expressway-E certificate
- D . The Expressway-E does not have the FQDN of Cisco UCM listed as a SAN in its certificate
Which mechanism does TLS use to validate identity?
- A . server certificate
- B . shared secret
- C . username and a password
- D . IP address of the peer
Refer to the exhibit.
When a Jabber user attempts to connect from outside of the organization, the user enters the login information as "[email protected]" and receives the error "Cannot find your services Automatically". The engineer tries to resolve SRV records used by Jabber.
DNS A record "expressway-e.example.com" points to the Expressway-E IP and "cucm.example.com" points to the Cisco Unified Communications Manager.
Which change resolves the DNS problem?
- A . Change cisco-uds to point to the Expressway-E FQDN.
- B . Change the collab-edge record to point to 5061.
- C . Remove the cisco-uds SRV record for the external DNS.
- D . Change the priority of the SRV record for cisco-uds.
