Question 1

Refer to the exhibit.

When configuring a search rule that routes calls to a zone, what occurs when 13358 is dialed?

Options :

A : 13358 is replaced by 135, and then is sent to the local zone.

B : 13358 is replaced by 135 and remains in the same zone.

C : 13358 is replaced by 135, and then is sent to the traversal zone.

D : 13358 is sent directly to the traversal zone.

Answer: C

Question 2

Refer to the exhibit. An engineer is deploying mobile and remote access in an environment that already had functioning Business to Business calling. Mobile and remote access SIP registrations are failing. To troubleshoot, SIP logs were collected. How is this issue resolved?

Options :

A :

Change the SIP profile on the SIP trunk for the Expressway-E to Standard SIP Profile for TelePresence Endpoint

B :

Change the “Incoming Port” in the SIP Trunk Security Profile for the Expressway-C to not match SIP line registrations

C :

Enable autoregistration for the appropriate DN range on the Cisco UCM servers running the CallManager service

D :

Write a custom normalization script since the “vcs-interop” normalization script does not allow registrations

Answer: B

Question 3

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

Options :

A :

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.

B :

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

C :

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.

D :

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

E :

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.

Answer: C,E

Question 4

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?

Options :

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.

Answer: A

Question 5

An organization with a domain name of example.com. Which two SRV records are valid for a SIP and H.323 communication? (Choose two.)

Options :

A : _sips._tcp.example.com

B : _sips._udp.example.com

C : _h323ls._udp.example com

D : _h323ls._tcp.example.com

E : _collab-edge._tls.example.com
