Refer to the exhibit. Which ds0-group option should you select to support automated number identification information collection on inbound calls for this digital T1 voice circuit?
In Cisco IOS routers, which chipset is the PVDM2-32 DSP hardware based on?
E. Broadcom 1500
Which two analog telephony signaling methods are most vulnerable to glare conditions? (Choose two.)
A. FXS Loop-start
B. FXO Ground-start
C. E&M Wink-start
D. E&M Delay-dial
E. E&M Immediate-start
F. E&M Feature Group D
The loop start signaling method is more common and is typically used by residential phone lines.
When a voice port is configured with loop start signaling, the device (telephone) closes the circuit loop that signals the CO voice port to provide dial tone; an incoming call is signaled on the CO by supplying a predefined voltage on the line. The loop start signaling method has one main disadvantage in that it has no method of preventing both sides of the connection from attempting to seize the line at the same time; this condition is referred to as glare. Because of this, loop start signaling is typically not used on high demand circuits.
With immediate-start, the calling side of the connection seizes the line by going off hook on the Elead and address information is sent using dual-tone multifrequency (DTMF) digits. Immediate start signaling is vulnerable to glare just like loop-start signaling.
Which digital modulation method is used to transmit caller ID information on analog FXS ports on Cisco IOS routers?
E. pulse dialing

A. multisite with centralized call processing
B. multisite with distributed call processing
C. local failover
D. remote failover
E. remote failover with Cisco Unified Communications Manager Express as SRST
Refer to the exhibit. All displayed devices are registered to the same Cisco Unified Communications Manager server and the phones are engaged in an active call. Assume that the provided configurations exist at the phone line level and multicast MOH is disabled cluster wide.

A. IP phone B receives audio source 2 from MOH server A.
B. IP phone B receives audio source 3 from MOH server A.
C. IP phone B receives audio source 2 from MOH server B.
D. IP phone B receives audio source 3 from MOH server B.
E. IP phone B receives audio source 1 from MOH server A.
Refer to the exhibit. What is the maximum number of inbound calls to 2001 before a Cisco Unified Communications Manager Express system returns user busy tone to any additional calls?
When calls are placed by certain Cisco Unified Communications Manager supplementary services, the Local Route Group feature will be bypassed. Which of these does not belong to the supplementary services?
A. Call Back
B. Call Forward

other users nearby.
C. The called party auto-answers the call in headset mode.
D. Only one-way audio exists from the called to the calling party.
E. Whisper Intercom is visual only, there is no audio.
Cisco Unified Communications Manager generates different types of alarms to indicate system- or process-related problems. “Code Yellow” is one of these alarms. Which of these system or process exceptions will trigger a Code Yellow alarm on Cisco Unified Communications Manager?
A. when a hard drive fails
B. when there is a memory leak
C. when the Cisco Unified Communications Manager application generates a core dump
D. when a database replication problem arises
E. when calls are throttled because of an unacceptably high delay in call handling
What will occur if a video bridge is not available during a video call setup on Cisco Unified Communications Manager using the Intelligent Bridge Selection feature?
A. The video call will fail, and the caller will receive a busy tone.
B. The video call will succeed, and Cisco Unified Communications Manager will use the default video image.
C. The video call will fail and will be forwarded to voice mail.
D. The video call will fall back to an audio-only call.
E. The video call will fail, and the caller will hear a message.
When a call is being established on a Cisco IOS MGCP gateway that is registered to Cisco Unified Communications Manager, which MGCP message is used by Cisco Unified Communications Manager to inform the gateway where to send RTP traffic?
A customer purchased 10,000 phone license units for a Cisco Unified Communications Manager cluster. How many phone license unit overdrafts are permitted in this Cisco Unified Communications Manager cluster?
E. Phone license unit overdrafts are never permitted
Which statement about MRGL on Cisco Unified Communications Manager is incorrect?

B. MRGL contains a prioritized list of Media Resource Groups.
C. Media resources that are not contained in any Media Resource Groups are not used by MRGL.
D. MRGL can contain a single Media Resource Group.
E. When a call is placed on hold, the MRGL of the device that put the call on hold determines which
MOH server is used to play music to the held device.
When implementing a Cisco Unified Communications Manager solution over an MPLS WAN, which two rules must be observed to prevent overrunning the priority queue? (Choose two.)
A. RSVP will transparently pass application IDs from the customer network across the MPLS WAN.
B. The media streams must be the same size in both directions.
C. Only the connection to the MPLS WAN where the Cisco Unified Communications Manager resides
must be enabled as a CE device.
D. The media has to be symmetrically routed.
E. If the CE is under corporate control, it may support either topology-aware or measurement-based CAC.
An H.225 call setup arrives at Cisco Unified Communications Manager for a directory number on an IP phone that is engaged in an active conversation. If call waiting is disabled for this directory number and none of the Call Forward settings are defined, which H.225 disconnects reason code will be sent to the originating H.323 gateway?
A. No Route To Destination
B. Normal Call Clearing
C. Subscriber Absent
D. User Busy
E. Network Busy
Which function does Cisco CTI Manager provide for Cisco Unified Communications Manager clusters?
A. Cisco CTI Manager and Cisco TSP provide TAPI applications with access to Cisco Unified
