QUESTION 73

Which Call Admission Control mechanism is supported for the Cisco Extension Mobility Cross Cluster solution?

 

A.

Location CAC

B.

RSVP CAC

C.

H.323 gatekeeper

D.

intercluster Enhanced Location CAC

E.

visiting cluster’s LBM hub

 

Correct Answer: B

Explanation:

Configuring extension mobility cross cluster (EMCC) is nothing you should take lightly. EMCC requires a lot of configuration parameters including the exporting and importing of each neighbor cluster’s X.509v3 digital certificates. EMCC is supported over SIP trunks only. Presence is another feature that’s only supported over SIP trunks. If you want to be able to perform scalable Call Admission Control (CAC) in a distributed multi-cluster call processing model, you will need to point an H.225 or Gatekeeper controlled trunk to an H.323 Gatekeeper for CAC… but if you want to support presence and EMCC between clusters and maintain CAC.

 

 

QUESTION 74

What is the number of directory URIs with which a Cisco Unified Communications Manager directory number can be associated?

 

A.

1

B.

up to 2

C.

up to 3

D.

up to 4

E.

up to 5

 

Correct Answer: E

Explanation:

Cisco Unified Communications Manager supports dialing using directory URIs for call addressing. Directory URIs look like email addresses and follow the username@host format where the host portion is an IPv4 address or a fully qualified domain name. A directory URI is a uniform resource identifier, a string of characters that can be used to identify a directory number. If that directory number is assigned to a phone, Cisco Unified Communications Manager can route calls to that phone using the directory URI. URI dialing is available for SIP and SCCP endpoints that support directory URIs.

 

 

QUESTION 75

Which statement about what happens to a hunt member who does not answer queuing-enabled hunt-list call in Cisco Unified Communications Manager 9.1 is true?

 

A.

The hunt member is logged off automatically and must press HLOG to log back in.

B.

The hunt member remains logged in if Automatically Logout Hunt Member on No Answer is not selected in Cisco Unified Communications Manager Service Parameters.

C.

The hunt member is logged off automatically and must manually reset the phone to log back in.

D.

The hunt member is logged off if Automatically Logout Hunt Member on No Answer is selected on the Line Group configuration page.

E.

The hunt member remains logged in if Automatically Logout Hunt Member on No Answer is not selected in Hunt Pilot configuration page.

 

Correct Answer: D

Explanation:

If a line member does not answer a queue-enabled call, that line member is logged off the hunt group only if the setting “Automatically Logout Hunt Member on No Answer” is selected on the line group page.

QUESTION 76

Which two user portion format conditions are true for directory URI on Cisco Unified Communications Manager 9.1 or later? (Choose two.)

 

A.

It supports the $ character.

B.

It support space between characters.

C.

It has a maximum length of 50 characters.

D.

It has a maximum length of 254 characters.

E.

It is always case-sensitive.

F.

It cannot be a directory number.

 

Correct Answer: AB

Explanation:

Cisco Unified Communications Manager supports the following formats in the user portion of a directory URI (the portion before the @ symbol):

 

Accepted characters are a-z, A-Z, 0-9, !, $, %, &, *, _, +, ~, -, =, \, ?, \, `, ,, ., /.

The user portion has a maximum length of 47 characters.

The user portion accepts percent encoding from %2[0-9A-F] through %7[0-9A-F]. For some accepted characters, Unified CM automatically applies percent encoding. See below for more information on percent encoding.

The user portion is case-sensitive or case-insensitive depending on the value of the URI Lookup Policy enterprise parameter. The default value is case-sensitive.

QUESTION 77

What is the maximum number of option 150 IP addresses that a Cisco IP SCCP phone will accept and use from a DHCP server?

 

A.

1

B.

2

C.

3

D.

4

E.

5

 

Correct Answer: B

Explanation:

Cisco Unified IP Phones use the option 150 value as the TFTP server IP address when Alternate TFTP option is set to No. You can assign only IP addresses as Option 150 values. A maximum of two IP addresses get used, and only the first two IP addresses that the DHCP server provides get accepted.

F.

Links must be created to the Shadow location.

 

Correct Answer: BCE

Explanation:

Recommendations and Design Considerations for Unified CM Session Management Edition Deployments

clip_image003

All leaf clusters that support E-L CAC should be enabled for intercluster E-L CAC with SME.

SME can be used as a centralized bootstrap hub for the E-L CAC intercluster hub replication network. See LBM Hub Replication Network, for more information.

All trunks to leaf clusters supporting E-L CAC should be SIP trunks placed in the shadow location to enable E-L CAC on the trunk between SME and the leaf clusters supporting E-L CAC.

For TelePresence video interoperability, see the section on Call Admission Control Design Recommendations for TelePresence Video Interoperability Architectures.

Connectivity from SME to any trunk or device other than a Unified CM that supports E-L CAC (some examples are third-party PBXs, gateways, Unified CM clusters prior to release 9.0 that do not support E-L CAC, voice messaging ports or trunks to conference bridges, Cisco Video Communications Server, and so forth) should be configured in a location other than a phantom or shadow location. The reason for this is that both phantom and shadow locations are non-terminating locations; that is, they relay information about locations and are legacy locations that allow for the transmission of location information in versions of Unified CM prior to 9.0, but they are not supported with Unified CM 9.x Enhanced Locations CAC. Shadow locations are special locations that enable trunks between Unified CM clusters that support E-L CAC to accomplish it end-to-end.

SME can be used as a locations and link management cluster.

 

 

QUESTION 80

Which statement about what happens to incoming calls to a Cisco Unified Communications Manager native call queue when no hunt members are logged in or registered is true?

 

A.

Calls are handled according to the Forward Hunt No Answer settings on the Hunt Pilot configuration page.

B.

Calls are handled according to the Not Available Hunt Option settings on the Line Group Configuration page.

C.

Calls are handled according to the Forward Hunt Busy settings on the Hunt Pilot configuration page.

D.

Calls are forward to the Forward Busy Calls To destination if configured; otherwise the calls are disconnected.

E.

Calls are handled according to the correspondent parameters under the Queuing section on the Hunt Pilot Configuration page.

 

Correct Answer: E

Explanation:

There are three main scenarios where alternate numbers are used:

When queue is full

When maximum wait time is met

When no hunt members are logged in or registered

When queue is full

Call Queuing allows up to 100 callers to be queued per hunt pilot (the maximum number of callers allowed in queue on a hunt pilot page). Once this limit for new callers been reached on a particular hunt pilot, subsequent calls can be routed to an alternate number. This alternate number can be configured through the Hunt Pilot configuration page (through the “Destination When Queue is Full” settings).

When maximum wait time is met

Each caller can be queued for up to 3600 seconds per hunt pilot (the maximum wait time in queue). Once this limit is reached, that caller is routed to an alternate number. This alternate number can be configured through the Hunt Pilot configuration page (through the “Maximum wait time in queue” settings).

When no hunt members are logged in or registered

In a scenario where none of the members of the hunt pilot are available or registered at the time of the call, hunt pilot configuration provides an alternate number field (through the “When no hunt members are logged in or registered” settings) where calls can be routed. For Call Queuing, a hunt pilot member is considered available if that member has both deactivated do not disturb (DND) and logged into the hunt group. In all other cases, the line member is considered unavailable or logged off.
