Question 1 of 89

Refer to the exhibit.

Which statement is true?

    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 89

Which three statements about configuring an encrypted trunk between Cisco TelePresence Video Communication Server and Cisco Unified Communications

Manager are true? (Choose three.)

    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 89

Which two options should be used to create a secure traversal zone between the Expressway-C and Expressway-E? (Choose two.)

    Correct Answer: A, C

    To create a secure traversal zone between Expressway-C and Expressway-E, Expressway-C and Expressway-E must trust each other's server certificates to ensure mutual authentication and encryption. Additionally, a separate pair of traversal zones must be configured if an H.323 connection is required and Interworking is disabled, to guarantee proper handling of H.323 traffic and maintaining the security of the traversal mechanism.

Question 4 of 89

What is the standard Layer 3 DSCP media packet value that should be set for Cisco TelePresence endpoints?

    Correct Answer: C

    For Cisco TelePresence endpoints, the standard Layer 3 DSCP value typically set for media packets, which includes video traffic, is AF41 (34). This designation is used to ensure high priority is given to video traffic, providing proper Quality of Service (QoS) to maintain the video quality. Other options like CS4 are generally used for signaling, not media packets.

Question 5 of 89

Which three commands are necessary to override the default CoS to DSCP mapping on interface Fastethernet0/1? (Choose three.)

    Correct Answer: A, C, D

    To override the default CoS to DSCP mapping on an interface, first, you need to globally enable the QoS functionality using the 'mls qos' command. Then, you define the CoS-to-DSCP map with 'mls qos map cos-dscp 0 10 18 26 34 46 48 56', which specifies how CoS values map to DSCP values. Finally, you configure the specific interface to trust the CoS values using 'interface Fastethernet0/1 mls qos trust cos'. This combination of commands effectively overrides the default CoS to DSCP mapping.
