Q4. Refer to the exhibit.
When the user of a phone registered to the Cisco Unified Communications Manager places a call to 3001 when the SAF network is down, what happens?
A. The call fails.
B. The call is rerouted to the PSTN with the constructed PSTN number as +442288223001
C. The call is rerouted to the PSTN with the constructed PSTN number as 442288223001
D. The call is rerouted to the PSTN with the constructed PSTN number as 0002288223001
E. The call is rerouted to the PSTN with the constructed PSTN number as +0002288223001
Answer: A
Explanation:
Incorrect Answer: B, C, D When the SAF forwarder loses network connection with its call-control entity, the SAF forwarder withdraws those learned patterns that were published by the call control entity. In this case, CCD requesting service marks those learned patterns as unreachable via IP, and the calls get routed through the PSTN gateway. Link:

Q5. Which action configures AAR to route the calls that have been rejected by the gatekeeper CAC through the PSTN?
A. Configure Cisco IP Phones for AAR.
B. Configure AAR to work with SRST.
C. Configure AAR to work with CTI route points.
D. This configuration is not possible using AAR.
Answer: D
Q6. On which two call legs is the media encryption enforced in a Collaboration Edge design? (Choose two.)
A. Expressway-C to Cisco Unified Communications Manager
B. Expressway-C to Expressway-E
C. Expressway-E to outside-located endpoint
D. Expressway-E to Cisco Unified Communications Manager
E. Expressway-C to internal endpoint
Answer: B,C
Q7. 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:

Q8. Scenario
There are two call control systems in this item. The Cisco UCM is controlling the DX650, the Cisco Jabber for Windows Client, and the 9971 Video IP Phone. The Cisco VCS and TMS control the Cisco TelePresence MCU, and the Cisco Jabber TelePresence for Windows.

Which device configuration option will allow an administrator to control bandwidth between calls placed between branches?
A. Media Resource Group List
B. Device Pool
C. Location
D. AAR Group
E. Regions
Answer: C
Explanation:
In Cisco Unified Communications Manager Administration, use the System > Location Info menu path to configure locations. Use locations to implement call admission control in a centralized call-processing system. Call admission control enables you to regulate audio quality and video availability by limiting the amount of bandwidth that is available for audio and video calls over links between the locations
Q9. In what Cisco solution is Simple Network-Enabled Auto Provision technology used?
A. Cisco Unified Gateway Duplication
B. Cisco Unified CallManager Redundancy
C. Cisco Unified SRST
D. Cisco Unified Call Survivability
Answer: C
Explanation:
Incorrect Answer: A, B, D When the system automatically detects a failure, Cisco Unified SRST uses Simple Network Auto Provisioning (SNAP) technology to auto-configure a branch office router to provide call processing for the Cisco Unified IP phones that are registered with the router Link: http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmesr st.html
Q10. Which of the following are two functions that ensure that the telephony capabilities stay operational in the remote location Cisco Unified SRST router? (Choose two)
A. Automatically detecting a failure in the network.
B. Initiating a process to provide call-processing backup redundancy.
C. Notifying the administrator of an issue for manual intervention.
D. Proactively repairing issues in the voice network.
Answer: A,B
Q11. Refer to the exhibit.
How many calls are permitted by the RSVP configuration?
A. one G.711 call
B. two G.729 calls
C. one G.729 call and one G.711 call
D. eight G.729 calls
E. four G.729 calls
Answer: B
Explanation:
Incorrect Answer: A, C, D, E In performing location bandwidth calculations for purposes of call admission control, Cisco Unified Communications Manager assumes that each call stream consumes the following amount of bandwidth:
.G.711 call uses 80 kb/s.
.G.722 call uses 80 kb/s.
.G.723 call uses 24 kb/s.
.G.728 call uses 26.66 kb/s.
.G.729 call uses 24 kb/s.
