• Question 207:

  An administrator works with an ISDN PRI that is connected to a third-party PBX. The ISDN link does not come up, and the administrator finds that the third-part PBX uses the QSIG signaling method. Which command enables the Cisco IOS Gateway to use QSIG signaling on the ISDN link?

  A. isdn switch-type basic-qsig

  B. isdn switch-type basic-ni

  C. isdn switch-type primary-qsig

• Question 208:

  A collaboration engineer troubleshoots issues with a Cisco IP Phone 7800 Series. The IPv4 address of the phone is reachable via ICMP and HTTP, and the phone is registered to Cisco UCM. However, the engineer cannot reach the CLI of the phone. Which two actions in Cisco UCM resolve the issue? (Choose two.)

  A. Enable Settings Access under Product Specific Configuration Layout in Cisco UCM.

  B. Enable FIPS Mode under Product Specific Configuration Layout in Cisco UCM.

  C. Enable SSH Access under Product Specific Configuration Layout in Cisco UCM.

  D. Set a username and password under Secure Shell Information in Cisco UCM.

  E. Disable Web Access under Product Specific Configuration Layout in Cisco UCM.

  Correct Answer: CD

  Enable ssh for phone, and then setup username and password so that engineer can login to phone via CLI

• Question 209:

  Which two steps are required for bulk configuration transactions on the Cisco UCM database utilizing BAT? (Choose two.)

  A. A server template must be created in Cisco UCM.

  B. A data file in Extensible Markup Language format by uploaded to Cisco UCM.

  C. A data file in Abstract Syntax Notation One format by uploaded to Cisco UCM.

  D. A device template must be created in Cisco UCM.

  E. A data file in comma-separated values format must be uploaded to Cisco UCM.

  Correct Answer: DE

  For bulk configuration transactions on the Cisco Unified Communications Manager database, the BAT process uses two components: a template for the device type and a data file in comma separated value (CSV) format that contains the unique values for configuring a new device or updating an existing record in the database. The CSV data file works in conjunction with the device template.

• Question 210:

  An engineer implements a new Cisco UCM based telephony system per these requirements:

  1.

  The local Ethernet bandwidth is sized based on the total bandwidth per call.

  2.

  A G.736 codec is used.

  3.

  The bit rate is 64 kbps.

  4.

  The codec sample interval is 10 ms.

  5.

  The voice payload size is 160 bytes per 20 ms.

  What should the size of the Ethernet bandwidth be per call?

  A. 31.2 kbps

  B. 38.4 kbps

  C. 55.2 kbps

  D. 87.2 kbps

  Correct Answer: D

  To calculate the Ethernet bandwidth per call, we need to take into account the total number of bytes per second in each direction (transmit and receive) and add additional overhead for Ethernet, IP, and UDP headers.

  The total number of bytes per second is calculated as follows:

  160 bytes per 20 ms = (160 bytes/20 ms) x (50 packets/s) = 8000 bytes/s

  The bit rate is 64 kbps, so we need to add an additional 8 kbps for overhead:

  64 kbps + 8 kbps = 72 kbps

  The total number of bytes per second including overhead is:

  72,000 bps / 8 bits per byte = 9,000 bytes/s

  Adding additional overhead for Ethernet, IP, and UDP headers, we can estimate that the total number of bytes per second will be approximately 12,000 bytes/s in each direction. Therefore, the Ethernet bandwidth per call should be:

  12,000 bytes/s x 8 bits per byte = 96 kbps

  Therefore, the correct answer is D. 87.2 kbps is not sufficient to support the required bandwidth per call.
