1. Question 111 · 450 in bank

   An administrator configures international calling on a Cisco UCM cluster and wants to minimize the number of route patterns that are needed. Which route pattern enables the administrator to match variable-length numbers?

   • A9.011@
   • B9.011#
   • C9.011*
   • D9.011!

   Show answer

   Answer: D

   Explanation

   The route pattern that enables the administrator to match variable-length numbers is D. 9.011! In Cisco Unified Communications Manager (UCM), the exclamation point (!) is used as a wild card character to represent any number of digits. By using 9.011! as a route pattern, the administrator can match any number that starts with 9.011, regardless of the number of digits that follow. Option A, 9.011@, is not a valid route pattern as the at symbol (@) is not recognized as a wild card character in Cisco UCM. Option B, 9.011#, is used to indicate the end of the number and is typically used when the user has finished dialing the number. It is not used to match variable-length numbers. Option C, 9.011*, is not a valid route pattern as the asterisk (*) is not recognized as a wild card character in Cisco UCM. Therefore, option D, 9.011!, is the correct answer as it allows the administrator to match any number that starts with 9.011, regardless of the number of digits that follow.

   A Cisco UCM administrator sets up new route patterns to support phones in four different locations, all with local gateways. The administrator wants to use the same route pattern for all four locations. How must the system be configured to achieve this goal?

   • AUse transforms in the route groups.
   • BUse standard local route groups.
   • CAdd a CSS to each local gateway.
   • DUse CSS alternate routing rules.

4. Question 114 · 450 in bank

   What is a characteristic of video traffic that governs QoS requirements for video?

   • AVideo is typically variable bit rate.
   • BVoice and video traffic are different, but they have the same QoS requirements.
   • CVideo is typically constant bit rate.
   • DVoice and video traffic are the same, so they have the same QoS requirements.

   Show answer

   Answer: A

   Explanation

   Suggestion: PLEASE Don't just answer by simply answering the question, provide your facts with relevant information, this way we can learn and understand from each other. A. Video is typically variable bit rate. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab11/collab11/cac.html Video, on the other hand, has a variable bit rate (is bursty) and has a medium to large footprint when compared to audio, as well as a wide operational range of 1:40 (250p at 15 fps vs 1080p at 60 fps). Cisco Press Book CLCOR 350-801 p.320 Cisco strongly recommends that you direct only voice traffic to it because voice traffic is well behaved, whereas other types of real-time traffic are not. Moreover, voice traffic requires that delay be nonvariable in order to avoid jitter. Real-time traffic such as video could introduce variation in delay, thereby thwarting the steadiness of delay required for successful voice traffic transmission.

8. Question 118 · 450 in bank

   Why would we not include an end user's PC device in a QoS trust boundary?

   • AThe end user could incorrectly tag their traffic to bypass firewalls.
   • BThe end user may incorrectly tag their traffic to be prioritized over other network traffic.
   • CThere is no reason not to include an end user's PC device in a QoS trust boundary.
   • DThe end user could incorrectly tag their traffic to advertise their PC as a default gateway.

   Show answer

   Answer: B

   Explanation

   I think the. answer is C. There is no reason not to include an end user's PC device m a QoS trust boundary Because the first 2 choices are talking about the End User not their PC.
