How must the engineer edit the inbound allow list rule?
- A . Go to Configuration > Unified Communications > HTTP allow list > Editable inbound rules to view.
- B . Go to Configuration > MRA > HTTP allow rules > Editable inbound rules to view, create, modify, or delete HTTP allow list rules.
- C . Go to Configuration > MRA > Editable Inbound rules to view, create, modify, or delete HTTP allow list rules.

An engineer is configuring Cisco Expressway-E and needs to implement toll fraud prevention.
Which configuration meets this requirement?
- A . Enable SIP ALG inspection on the network address translation firewall.
- B . Enable and configure local call policy.
- C . Enable and configure the Expressway-E firewall.
- D . Configure the external firewall to block specific IPs.
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.
A company is implementing Cisco Webex but has existing legacy Cisco video endpoint registered on-premises. The administrator of Webex wants the SIP address of these rooms to appear in the directory listing on Webex registered endpoints and in the Webex App.
How can this be configured?
- A . Using the Directory Connector, room resources without Webex licenses can be synchronized with Webex to make the SIP address appear in the phonebook of the Webex App or the endpoint.
- B . Using the Directory Connector, room resources with flex licenses only can be synchronized with Webex to make the room appear in the phonebook of the Webex App or the endpoint. SIP address is then entered from Control Hub because it will not match the field.
- C . Using the Directory Connector, room resources with flex licenses only can be synchronized with Webex to make the SIP address appear in the phonebook of the Webex App or the endpoint.
- D . Using the Directory Connector, room resources without Webex licenses can be synchronized with Webex to make the room appear in the phonebook of the Webex App or the endpoint. SIP address is then entered from Control Hub because it will not match the field.
Which DNS record and port combination must be resolved externally for Mobile and Remote Access to be used?
- A . _collab-edge on port 8443
- B . _cisco-uds-edge on port 5061
- C . _collab-edge on port 5061
- D . _cisco-uds on port 8443
Refer to the exhibit.
Call policy rules on an Expressway-E prevent external callers from the internet from calling a VIP whose URI is [email protected].
Which additional configuration setting is required for this call policy to function as intended?
- A . The default zone on the Expressway-E must not be configured to treat as authenticated.
- B . A search rule must be configured with an extract match forvip^cisco.com to pass the call to the Expressway-C.
- C . The Cisco TelePresence endpoint registered with the URI [email protected] must be set in *do not disturb" mode.
- D . SIP TLS must be disabled on the Expressway-E.
An engineer must configure the zone to connect to an Expressway-E using Single NIC with NAT. The internal IP address is 192.168.10.63, and the NAT address is 203.0.113.5.
What must the engineer configure on the Expressway-C to meet this requirement?
- A . traversal zone with the peer address 192.168.10.63
- B . neighbor zone with the peer address 192.168.10.63
- C . traversal zone with the peer address of 203.0.113.5
- D . neighbor zone with the peer address of 203.0.113.5
Refer to the exhibit.
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.
What is a benefit of Cisco Webex Messenger Cloud deployment?
- A . Cloud deployment is more secure than an on-premises deployment.
- B . There is no additional cost to use a cloud deployment.
- C . Cloud deployment allows interoperability between Cisco Jabber and Webex Teams users.
- D . Cloud deployment is taster than using an on-premises deployment.
