Question 1 of 395

Refer to the exhibit.
Exam 300-075: Question 1 - Image 1

Which statement is true?

Endpoints can make calls to unknown IP addresses without the VCS querying any neighbors.

If the VCS receives a call to an unknown IP address, it queries its neighbors for the remote address and if permitted, it routes the call through the neighbor.

Endpoints that are registered directly to the VCS can call only an IP address of a system that is also registered directly to that VCS.

Dialing by IP address is not supported on VCS.

Correct Answer: A

The configuration settings indicate that the Call Loop Detection Mode is enabled and the Call Routed Mode is set to 'Always,' which means that the VCS will always route the call signaling. Additionally, the setting for Call Services CallsToUnknownIPAddresses is set to 'Direct,' which allows endpoints to make calls to unknown IP addresses without the VCS querying any neighbors. Therefore, endpoints can indeed make calls to unknown IP addresses directly.

Question 2 of 395

Which three statements about configuring an encrypted trunk between Cisco TelePresence Video Communication Server and Cisco Unified Communications
Manager are true? (Choose three.)

The root CA of the VCS server certificate must be loaded in Cisco Unified Communications Manager.

A SIP trunk security profile must be configured with Incoming Transport Type set to TCP+UDP.

The Cisco Unified Communications Manager trunk configuration must have the destination port set to 5061.

A SIP trunk security profile must be configured with Device Security Mode set to TLS.

A SIP trunk security profile must be configured with the X.509 Subject Name from the VCS certificate.

The Cisco Unified Communications Manager zone configured in VCS must have SIP authentication trust mode set to On.

The Cisco Unified Communications Manager zone configured in VCS must have TLS verify mode set to Off.

Correct Answer: A, C, D

To configure an encrypted trunk between Cisco TelePresence Video Communication Server (VCS) and Cisco Unified Communications Manager (CUCM), the root CA of the VCS server certificate must be loaded in CUCM. This ensures that CUCM can validate the server certificate presented by VCS. The CUCM trunk configuration must have the destination port set to 5061 as this is the standard port for SIP over TLS. Additionally, a SIP trunk security profile must be configured with the Device Security Mode set to TLS to ensure that the communication over the trunk is encrypted.

Question 3 of 395

Which two statements regarding IPv4 Static NAT address 209.165.200.230 has been configured on a VCS Expressway are true? (Choose two.)

The Advanced Networking or Dual Network Interfaces option key has been installed.

VCS rewrites the Layer 3 source address of outbound SIP and H.323 packets to 209.165.200.230.

VCS applies 209.165.200.230 to outbound SIP and H.323 payload messages.

With static NAT enabled on the LAN2 interface, VCS applies 209.165.200.230 to outbound H.323 and SIP payload traffic exiting the LAN1 interface.

Correct Answer: A, C

Question 4 of 395

Which configuration does Cisco recommend for the peer address on the Expressway-C secure traversal zone when the Expressway-E has one NIC enabled?

Expressway-E internal IP address

Expressway-E external IP address

Expressway-E internal FQDN

Expressway-E external FQDN

Correct Answer: D

Question 5 of 395

If delegated credentials checking has been enabled and remote workers can register to the VCS Expressway, which statement is true?

H.323 message credential checks are delegated.

SIP registration proxy mode is set to On in the VCS Expressway.

A secure neighbor zone has been configured between the VCS Expressway and the VCS Control.

SIP registration proxy mode is set to Off in the VCS Expressway.

Correct Answer: D
