Q63. A Cisco Unified Communications Manager cluster is installed in headquarters only. 

How can international calls be blocked while national calls are allowed for branch office Cisco IP Phones during a WAN failure? 

A. Configure CSS and partitions in Cisco Unified Communications Manager and apply the CSS and partitions to the SRST ISR. 

B. Configure CSS and partitions in the SRST ISR.

Q64. Which two statements about symmetric encryption are true? (Choose two.) 

A. With symmetric encryption, the encryption key equals the decryption key. 

B. Symmetric encryption is commonly used to sign asymmetric keys. 

C. Symmetric encryption is a good choice for real-time encryption of bulk data. 

D. Symmetric encryption uses asymmetric keys. 

Answer: A,C 

Explanation: 

Incorrect Answer: B, D There are two basic techniques for encrypting information: symmetric encryption (also called secret key encryption) and asymmetric encryption (also called public key encryption.) in symmetric key As long as both sender and recipient know the secret key, they can encrypt and decrypt all messages that use this key. A public key is made freely available to anyone who might want to send you a message. A second, private key is kept secret, so that only you know it. Link:

Answer:

Explanation: 

Incorrect Answer: A, B, C, E 

in time of srst configuration on router, please configure a dial-peer so that call flow in SRST mode.

Answer:


Q68. Which process can localize a global E.164 with + prefix calling numbers for inbound calls to an IP phone so that users see the calling number in a local format? 

A. Calling number localization is done using translation patterns. 

B. Calling number localization is done using route patterns. 

C. Calling number localization is done by configuring a calling party transformation CSS at the phone. 

D. Calling number localization is done by configuring a calling party transformation CSS at the gateway. 

E. Calling number localization is done by configuring the phone directory number in a localized format. 

Answer:


Q69. Company X has a Cisco Unified Communications Manager cluster and a VCS Control server with video endpoints registered on both systems. Users find that video endpoints registered on Call manager can call each other and likewise for the endpoints registered on the VCS server. The administrator for Company X realizes he needs a SIP trunk between the two systems for any video endpoint to call any other video endpoint. Which two steps must the administrator take to add the SIP trunk? (Choose two.) 

A. Set up a SIP trunk on Cisco UCM with the option Device-Trunk with destination address of the VCS server. 

B. Set up a subzone on Cisco UCM with the peer address to the VCS cluster. 

C. Set up a neighbor zone on the VCS server with the location of Cisco UCM using the menu option VCS Configuration > Zones > zone. 

D. Set up a SIP trunk on the VCS server with the destination address of the Cisco UCM and Transport set to TCP. 

E. Set up a traversal subzone on the VCS server to allow endpoints that are registered on Cisco UCM to communicate. 

Answer: A,C 


Q70. When an incoming PSTN call arrives at an MGCP gateway, how does the called number get normalized to an internal directory number in Cisco Unified Communications Manager? 

A. Normalization is done by configuring the significant digits for inbound calls on the MGCP gateway. 

B. Normalization is done using route patterns. 

C. Normalization is done using the gateway incoming called party prefixes based on number type. 

D. Normalization is done using the gateway incoming calling party prefixes based on number type. 

E. Normalization is achieved by local route group that is assigned to the MGCP gateway.
