   During the Cisco IP Phone registration process, the TFTP download fails. What are two reasons for this issue? (Choose two.)

   • AOption 100 string was not specified, or an incorrect Option 100 string was specified
   • BThe Cisco IP Phone does not know the IP address of any of the Cisco UCM Subscriber nodes
   • CThe Cisco IP Phone does not know the IP address of the TFTP server
   • DOption 150 string was not specified, or an incorrect Option 150 string was specified
   • EThe DNS server was not specified, which is needed to resolve the DHCP server IP address

   Show answer

   Answer: CD

   Explanation

   Going for C and D: A: Wrong, option 100 doesn't have anything to do with TFTP servers. B: Also seems wrong, the phone needs to know the IP of the TFTP server, not the IP of the subs. C: Makes sense, this would of course trigger the failure. D: Also makes sense, option 150 is used to obtain TFTP server addresses. E: Could be right, but you don't necessarily need a DNS server if option 66 or 150 are directly providing the IP of the TFTP server.

2. Question 192 · 450 in bank

   An administrator must make a pattern to route calls to two different destinations: john.doe@company.com and jane.doe@company.com. Which type of patterns are needed in the Cisco UCM, and what must the pattern look like?

   • AA SIP route pattern that looks like this: *@company.com
   • BA regular route pattern with the URI feature enabled in the configuration page. The pattern must look like this: MATCH(*.doe@company.com)
   • CA regular route pattern with the URI feature enabled in the configuration page. The pattern must look like this: (*@company.com)
   • DA SIP route pattern that looks like this: company.com

   Show answer

   Answer: D

   Explanation

   You're right pan_tarej : SIP Route pattern does not accept @-symbol. "Domain name examples are cisco.com, my-pc.cisco.com, *.com, rtp-ccm[1-5].cisco.com. Valid characters for domain names are [, -, ., 0-9, A-Z, a-z, *, and ]." https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/10_0_1/ccmcfg/CUCM_BK_C95ABA82_00_admin-guide-100/CUCM_BK_C95ABA82_00_admin-guide-100_chapter_0100111.pdf

   Which SNMP service must be activated manually on the Cisco UCM after installation?

   • AHost Resources Agent
   • BCisco CallManager SNMP
   • CConnection SNMP Agent
   • DSNMP Master Agent

   Show answer

   Answer: B

   Explanation

   SNMP Master Agent serves as the primary service for the MIB interface. You must manually activate Cisco CallManager SNMP service; all other SNMP services should be running after installation.

   Which QoS marking is used when an administrator configures voice call signaling?

   • AEF
   • BCS3
   • CCS4
   • DAF41

   Show answer

   Answer: B

   Explanation

   Call-Signaling traffic should be marked as DSCP CS3 per the QoS Baseline (during migration, it also can be marked the legacy value of DSCP AF31). https://www.ciscopress.com/articles/article.asp?p=357102

7. Question 197 · 450 in bank

   According to QoS guidelines, what is the packet loss for streaming video?

   • Anot more than 5%
   • Bnot more than 8%
   • Cnot more than 1%
   • Dnot more than 3%

   Show answer

   Answer: A

   Explanation

   https://www.ciscopress.com/articles/article.asp?p=357102&seqNum=2 Streaming-Video When addressing the QoS needs of Streaming-Video traffic, the following guidelines are recommended: Streaming-Video (whether unicast or multicast) should be marked to DSCP CS4, as designated by the QoS Baseline. Loss should be no more than 5 percent. Latency should be no more than 4 to 5 seconds (depending on the video application's buffering capabilities). There are no significant jitter requirements.

8. Question 198 · 450 in bank

   An administrator is configuring a new Cisco UCM with PSTN capabilities. Due to bandwidth constraints, audio compression is used on the codec. DTMF must work as expected because the customer is calling many call centers where the users must select options in the call. Where is DTMF out-of-band in a CCM 12.5 with SIP-based gateway configured?

   • Ain the DTMF setting under SIP profile on the Cisco Unified Border Element
   • Bin DTMF settings in the audio codec preference list under regions in the Cisco UCM
   • Cin regions on the Cisco UCM where you set the appropriate codec to use
   • Din the dial peer on the Cisco IOS router

   What are two reasons that AF41 is marked for the audio and video channels of a video call? (Choose two.)

   • Ato allow high-definition quality calls over low-speed links
   • Bto give video calls a higher priority than AF41 in the QoS policy
   • Cto provide separate classes for audio calls and video calls
   • Dto preserve lip synchronization between the audio and video channels
   • Eto prioritize video over other high-priority traffic classes

   Show answer

   Answer: CD

   Explanation

   QoS Marking Differences Between Video Calls and Voice-Only Calls The voice component of a call can be classified in one of two ways, depending on the type of call in progress. A voice-only telephone call would have its media classified as CoS 5 (IP Precedence 5 or PHB EF), while the voice channel of a video conference would have its media classified as CoS 4 (IP Precedence 4 or PHB AF41). All the Cisco IP Video Telephony products adhere to the Cisco Corporate QoS Baseline standard, which requires that the audio and video channels of a video call both be marked as CoS 4 (IP Precedence 4 or PHB AF41). The reasons for this recommendation include, but are not limited to, the following: To preserve lip-sync between the audio and video channels To provide separate classes for audio-only calls and video calls

    • BPing Sweep reports ג€unmanagedג€ state devices.
    • CThe Cisco Discovery Protocol table is shared among devices.
    • DSimple Network Managed Protocol is enabled on each device to poll specific values periodically.

    Show answer

    Answer: D

    Explanation
