Q111. Which three commands are necessary to override the default CoS to DSCP mapping on interface Fastethernet0/1? (Choose three.)
A. mls qos map cos-dscp 0 10 18 26 34 46 48 56
B. mls qos map dscp-cos 8 10 to 2
C. mls qos
D. interface Fastethernet0/1mls qos trust cos
E. interface Fastethernet0/1mls qos cos 1
F. interface Fastethernet0/2mls qos cos 1
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 is controlling the SX20, the Cisco TelePresence MCU, and the Cisco Jabber TelePresence for Windows.
Use the exhibits to answer the following questions.
SX20 System Information
A new DX650 IP phone with MAC address D0C7.8914.132D, IP address is 172.18.32.119 has been added to the Cisco Unified Communications Manager, but is not registering properly.
What is causing this failure?
A. Device Pool cannot be default.
B. The DX650 is the incorrect calling search space.
C. The DX650 Phones does not support SIP.
D. The location Hub_None has not been activated.
E. The DX650’s MAC address is incorrect in the Cisco UCM.
From the screen capture below we can see that the DX650 phone’s MAC address was incorrectly entered as D0C78914131D, not D0C78914132D.
Q113. Which two statements about remote survivability are true? (Choose two.)
A. SRST supports more Cisco IP Phones than Cisco Unified Communications Manager Express in SRST mode.
B. Cisco Unified Communications Manager Express in SRST mode supports more Cisco IP Phones than SRST.
C. MGCP fallback is required for ISDN call preservation.
D. MGCP fallback functions with SRST.
Q114. Which sign is prefixed to the number in global call routing?
Q115. You are deploying a Cisco Unified Communications Manager solution with MGCP gateways at multiple locations. Which firewall and ACL configuration must you perform to allow the MCGP gateways to function correctly?
A. Allow access to TCP port 2428.
B. Block TCP port 1720.
C. Open access to all TCP and UDP ports.
D. Allow access to TCP port 1720.
E. Block access to TCP ports 2427 and 2428.
Q116. To preserve analog calls in an MGCP switchback event, which three commands must be configured in the MGCP fallback router? (Choose three.)
C. voice service voip
F. no h225 timeout keepalive
Incorrect Answer: B, D, E these additional command for call preservation when using MGCP fallback: voice service voip h323 no h225 timeout keepalive Reference. CCNP Voice CIPT2 642-457 Quick Reference, 2nd Edition
Q117. While operating in SRST, what is needed to route calls outside of the remote site location to the PSTN?
A. SIP trunk
B. CallManager route patterns
C. translation patterns
D. POTS dial peers
E. VOIP dial peers
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.
Q118. What user profile is used to define the settings for a user on login?
A. Device Profile
B. Group Profile
C. Pool Profile
D. Specific Profile
Q119. Refer to the exhibit.
The HQ site uses area code 650. The BR1 site uses area code 408. The long distance national code for PSTN dialing is 1. To make a long distance national call, an HQ or BR1 user dials access code 9, followed by 1, and then the 10-digit number.
Both sites use MGCP gateways. AAR must use globalized call routing using a single route pattern. Assume that all outgoing PSTN numbers are localized at the egress gateway as shown in the exhibit.
Which partition should be configured in the AAR CSS applied at the phones?
A. PSTN partition
B. LD partition
C. The HQ AAR CSS must include a partition assigned to route pattern 91408XXXXXXX. The BR1 AAR CSS must include a partition assigned to route pattern 91650XXXXXXX.
D. AAR CSS must contain translation pattern 9.1[2-9]XX[2-9]XXXXXX for each site that must be globalized. Otherwise the called numbers will not be localized at the egress gateway.
Q120. 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.
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:
