QUESTION 82  (Topic 3)

 

Which statement best describes Urgent Priority operations in relation to call routing in Cisco Unified Communications Manager?

 

A.

An Urgent Priority operation is initiated whenever an IP phone user presses the # key for immediate dialing.

B.

An Urgent Priority operation can be configured on a route pattern to force immediate routing when a first match is detected, even if there are longer route patterns that are also potential matches.

C.

Urgent Priority operations are automatically performed in translation patterns and emergency route patterns in order to force immediate routing when a first match is detected, even if there are longer route patterns that are also potential matches.

D.

Urgent Priority operations cannot be used for VoIP route patterns; they are only applicable to PSTN route patterns.

 

Answer: B

Explanation:The Urgent Priority check
box is often used to force immediate routing ofcertain calls as soon asamatch isdetected, without waiting for the T302 timer to expire when additional longer potential matches exist

 

 

QUESTION 83  (Topic 3)

 

The CSS on a line includes the partitions 911, internal and local. The CSS on the device includes the partitions 911, internal, local and long distance. Which CSS will be used if the phone user dials a local number?

 

A.

The device CSS will be used since the device CSS is always used first on an IP phone.

B.

Since the dialed digits are match to partition is in both Calling Search Spaces the call will use both matched partitions in both calling Search Spaces in a round robin format.

C.

If there is both a line and device CSS the line device will only be used.

D.

The line and device CSSs will be combined and the device CSS will take precedence.

E.

The line and device CSSs will be combined and the line CSS will take precedence.

 

Answer: E

Explanation:Explanation : the Line CSS configured on the directory number associated with the user’s device Profile

QUESTION 84  (Topic 3)

 

Which three of these are characteristics of a Cisco Unified Communications Manager software-based Media Termination Point? (Choose three.)

 

A.

The codec and packetization of both call legs must be identical.

B.

This Media Termination Point type does not require any DSP resources on the Cisco router.

C.

DSP resources are required.

D.

It can provide G.711 mu-law to G.711 a-law conversion and vice versa.

E.

It can provide packetization conversion for a given codec (for example, if one call leg is using a 20-ms sample size, but the other call leg is using a 30-ms sample size).

F.

This Media Termination Point type is typically used for RSVP agent configurations or Cisco Unified Border

Element media flow-through configurations.

 

Answer: BDE

Explanation:Three MTP types can be configured:

 

 

  Software MTP: provided by the Cisco IP Voice Media Streaming App service on Cisco Unified

Communications Manager:

 – This MTP type can convert G.711 mu-law to G.711 a-law and vice versa. — This MTP type can packetize conversion for a given codec; for example, when one call leg uses 20-ms

sample size and the other call leg uses 30-ms sample size.  Software MTP: configured on Cisco IOS routers: – This MTP type does not require any DSP resources onthe Cisco router. Enable Cisco IOS Software MTPs by using the maximum session software <n> command. As many as 500 software-based sessions can be configured. The codec and packetization of both call legs must be identical. – This MTP type typically is used for Resource Reservation Protocol (RSVP) agent configurations or Cisco Unified Border Element media flow-through configurations. — Cisco Unified Communications Manager does not
differentiate between software-and hardware-based Cisco IOS MTP configurations. Every Cisco IOS Software MTP is considered as a hardware MTP in Cisco Unified Communications Manager.

 

 

QUESTION 85  (Topic 3)

 

The abc.com Lumber Company would like to use AAR to reroute calls made from HQ to remote locations when those calls are rejected by the IP WAN because of insufficient bandwidth. The abc.com Lumber Company uses 5-digit dialing to all locations.

 

abc.com Headquarters has a DID range from 770-555-0001 to 770-557-0500 and the Macon facility has a DID range from 912-556-0500 to 912-556-0550.How should the external phone masks be configured?

 

A.

770557XXXX

B.

9125560XXX

C.

770555XXXX

D.

77055XXXXX

 

Answer: D

 

 

QUESTION 86  (Topic 3)

 

 

A dial plan uses six-digit numbers, in which the first two digits are a site code and the last four digits are an extension. Access codes must begin with a 7 or 8 and the second digit must be a 0, 1, 5, or 9. Calls within a site are placed using just the four digit extensions. Which two route patterns will support this dial-plan requirement? (Choose two.)

 

A.

[^78][^234678].XXXX

B.

[7-8][^0159].XXXX

C.

[78][0159].XXXX

D.

[^0-69][^2-4678].XXXX

E.

[^0-6,9][2-4,6-8].XXXX

F.

[7-8][234678].XXXX

 

Answer: CD

 

 

QUESTION 87  (Topic 3)

 

You are the network administrator. What is the correct order to implement call coverage?

 

clip_image001

(I) (II) (III) (V) (IV)

B.

(IV) (I) (II) (III) (V)

C.

(V) (IV) (i) (ii) (Hi)

D.

(IV) (I) (II) (V) (III)

QUESTION 88  (Topic 3)

 

What is the accessibility of a DN assigned to the <None> partition?

 

A.

accessible by all devices regardless of the CSS configured on the device on the calling

 

 

device

B.

not accessible by any device

C.

only accessible by devices that have the None CSS configured

D.

not accessible by any device by default, unless enabled in the Cisco Unified Communications Manager service parameters

 

Answer: A

Explanation:Explanation : Before configure any partitions or calling search spaces, all directory numbers (DN) reside in a special partition named <None>, and all devices are assigned a calling search space also named <None>.

When you create custom partitions and calling search spaces, any calling search space that you create

also contains the <None> partition, while the <None> calling search space contains only the <None>

partition.

E.

places more call-routing intelligence at the gateway

 

Answer: BD

Explanation:Explanation : route group can be added to route list not route pattern.

QUESTION 90  (Topic 3)

 

Which of these two route patterns will be matched if 99118855 is dialed with en bloc dialing enabled?

 

9.911 Urgent Priority Enabled

 

9.[2-9]XXXXXX

 

A.

9.911 will always be matched because it is tagged as Urgent Priority.

B.

9.[2-9]XXXXXX will be matched first because en bloc dialing is being used. The Urgent Priority tag will be ignored in this case.

C.

There will be a tie between the two route patterns, and a random selection will be made.

D.

The 9.911 pattern will be dialed first and if the call is not successful, then the other potential match will be attempted.

E.

Cisco Unified Communications Manager will not be able to determine which pattern to match. For this reason, it will generate an annunciator message that the call cannot be completed as dialed.
