Refer to the exhibit. An Expressway-C and Expressway-E are configured for B2B calling and the Expressway-E zone is set to TLS Verify Currently, calls do not reach the Expressway-C. The Traversal Client zone on the Expressway-C for B2B reports the information in the exhibit for the Peer 1 address.
Which action resolves this error?
Configure the Expressway-C Traversal Client zone Peer 1 address with the fully qualified domain name of the Expressway-E.
Configure the Expressway-C Traversal Client zone transport protocol with TCP.
Add a server certificate to the Expressway-C that is signed by a certificate authority.
Add an intermediate certificate to the Expressway-C that is signed by a certificate authority.
Refer to the exhibit. Which inbound connection should an administrator configure on the outside firewall?
Media: UDP 36000 to 36011
XMPP: TCP 5222
SIP: TCP 5061
HTTPS (tunneled over SSH between C and E): TCP 2222
How does an administrator configure an Expressway to make sure an external caller cannot reach a specific internal address?
block the call with a call policy rule in the Expressway-E
add the specific URI in the firewall section of the Expressway and block it
configure FAC for the destination alias on the Expressway
add a search rule route all calls to the Cisco UCM
An engineer wants to configure a zone on the Expressway-E to receive communications from the Expressway-C in order to allow inbound and outbound calls.
How is the peer address configured on the Expressway-C when Expressway-E has only one NIC enabled and is using static NAT mode?
Expressway-E DHCP
Cisco UCM FQDN
Cisco UCM DHCP
Expressway-E FQDN
Refer to the exhibit. Which two outbound connections should an administrator configure on the internal firewall? (Choose two.)
XMPP: TCP 7400
SIP: TCP 7001
SIP TCP 5061
Media: UDP 36012 to 59999
HTTPS: TCP 8443
Refer to the exhibit. The firewall has been configured from NAT 192.168.108.2 to 100.64.0.1. Which configuration changes are needed for an Expressway-E with dual network interfaces?
An engineer is deploying an Expressway solution for the SIP domain Cisco.com. Which SRV record should be configured in the public DNS to support inbound B2B calls?
_collab-edge._tls.cisco.com
_cisco-uds._tcp.cisco.com
_sip._tcp.cisco.com
_cuplogin._tcp.cisco.com
A call is sent by Cisco UCM to Expressway with a URI of [email protected]. If (7508...)@expc1a\.pod8\.test\.lab.* is the pattern string, what would be the replacement string of the transform in Expressway to re-write the call so that it becomes [email protected]?
\1@conf\.pod8.test.lab.@
\1@conf\.pod8\.test\lab.*
\[email protected]\.test\.lab
\1@conf\.pod8\.test.lab.!
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?
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.
The calls are failing because there are insufficient licenses. Additional licenses must be installed for the Expressway to route these calls.
The current search rule does not match the call, so the search rule must be modified to include a SIP Variant of "Standards-Based".
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.
Refer to the exhibit. A new neighbor zone is added for a new Cisco Meeting Server, but the zone is showing a SIP status of failed from the time the zone it was created. What should be done to resolve this issue?
The search rule must be changed to continue on match
The existing zone using ID 7 must be deleted
More bandwidth must be added to the appropriate pipes
The underlying DNS issue must be resolved
