Questions # 11:

Refer to the exhibit.

Question # 11

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 “EndpointB@pod1.local” is also registered. How is this issue resolved?

Options:

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.

Expert Solution

Questions # 12:

An Expressway Server has both network protocols (IPv4 and IPv6) enabled. Which two behaviors are correct? (Choose two.)

Options:

If the calling endpoint is on an IPv4-Only network and the called endpoint is on an IPV6-Only network, a NAT64 device must convert the IPv4 addresses to IPv6 addresses.

Endpoints register with either IPv4 or IPv6 addresses, but dual-stack endpoints choose IPv6 protocol by default.

If the calling endpoint is on an IPv4-Only network and the called endpoint is on an IPv6-Only network, the Expressway Server act as a gateway and convert the two protocol versions.

Endpoints register only with IPv6 addresses on an Expressway Server with IPv6 protocol enabled regardless of the state of IPv4 protocol.

Endpoints register with either IPv4 or IPv6 addresses, and endpoints decide which protocol to use by the format of the configured Expressway Server IP address.

Expert Solution

Questions # 13:

Which two scenarios need a proper DNS configuration on Expressway servers? (Choose two.)

Options:

Expressway servers verify the common name attribute in server certificates.

Expressway servers route calls based on SIP URI.

Admins avoid IP address configuration for neighbor zone peers.

Expressway servers use NTP peer authentication for secure time updates.

Admins download software updates from the Cisco website via WebUI.

Questions # 14:

Which configuration is required when implementing Mobile and Remote Access on Cisco Expressway?

Options:

IPS

SAML authentication

Cisco Unified CM publisher address

SSO

Expert Solution

Questions # 15:

An Expressway pairs deployed for Mobile and Remote Access. An administrator installs a new server certificate on the Expressway-E. After installing the new certificate, the UC Traversal zone between Expressway-C and Expressway-E is active. Still, Jabber Mobile and Remote Access clients cannot log in over the Expressway. The certificate Common Name is the FQDN of Expressway-E, “expe01 example.com”, and the certificate contains no additional names. Which Subject Alternate Name must be added to the certificate to allow Jabber Mobile and Remote Access clients to log in successfully?

Options:

FQDN of the Expressway-C, “expc01.example.local”

registration domain, “example.com” or “collab-edge.example.com”

Cisco UCM cluster FQDN, “cucmcluster.example.local”

FQDN of the Expressway-E, “expe01.example.com”

Questions # 16:

Refer to the exhibit.

Question # 16

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?

Options:

Another node in the cluster is used and an intra-cluster cascade between the two Video Mesh nodes is formed.

The call is queued.

The call fails.

Another node in the cluster is used and an intra-cluster cascade between Webex and the new Video Mesh node is formed.

SIP TCP 5061

XMPP TCP 5222

Expert Solution

Questions # 18:

Which role does Call Policy play when preventing toll fraud on Expressways?

Options:

It controls which calls are allowed, which calls are rejected, and which calls are redirected to a different destination.

It changes the calling and called number on a call.

It changes the audio protocol used by a call through Expressways.

It changes the audio codec used in a call through Expressways.
