第1题:
When calls are denied by call admission control (CAC), the calls are rerouted through the PSTN via the use of which Cisco CallManager feature?()
第2题:
Acme Company has several offices around the country. The company has deployed a VoIP network with Cisco Unified CallManager in a multisite centralized configuration but the is a requirement to place a call agent at some of the remote sites. Which IOS gateway feature should be deployed at the remote site to enable local call control?()
第3题:
When using WMM Call Admission Control, what are the default bandwidth values for video on802.11a/n()?
第4题:
Acme Company has offices around the country. With the use of Cisco Unified CallManager, the company has deployed a VoIP network in a multisite centralized configuration. Which IOS gateway feature should be deployed to enable VoIP devices to register with a local gateway and continue to function when the connection to the Cisco Unified CallManager is broken? ()
第5题:
regions
partitions
locations
device Pools
第6题:
Gatekeeper multizone
Call Admission Control (CAC)
Automatic Alternate Routing (AAR)
Survivable Remote Site Telephony (SRST)
Cisco Unified CallManager Express (CME)
第7题:
Analog phones, connected to the PSTN, act as internal call agents if IP communication to the CallManager is lost.
An onsite gateway reroutes calls over the PSTN if IP communication to the CallManager is lost.
The IP phones can reroute calls over the PSTN if IP communication to the CallManager is lost.
Local voice gateways can assume the function of a call agent if IP communication to the CallManager is lost.
IP phones use an internal call agent if IP communication to the CallManager is lost.
第8题:
CAC is used to allocate enough bandwidth for the number of calls that are allowed on the VoIP network.
CAC is used to protect the quality of the voice calls by preventing call establishment if enough resources are not available on the network.
CAC provides queuing mechanisms for voice calls if the packets exceed the configured or budgeted rate.
In a VoIP network the CAC can be replaced with the LLQ QoS mechanism if it has been properly implemented.

第10题:
codec
link speed
Layer 2 encapsulation
packet overhead (IP/UDP/RTP)
link delay
total number of simultaneous calls that are allowed
第11题:
nominally 30 percent to best align with Cisco Unified Communications System recommendations
100 percent to ensure that the VoWLAN calls can use all the available bandwidth, if needed
system default of 75 percent
40 to 60 percent
voice CAC should be left disabled unless wired QoS is configured

Traffic policing
Call Admission Control
QoS Link Congestion Management
Oversubscription Link Detection
第13题:
What is the Cisco recommended setting for the Cisco Unified Wireless Network WLC Voice Call Admission Control Max RF Bandwidth to support the Cisco Unified Wireless IP Phone 7921G?()
第14题:
In a Teleworker deployment with a single IP phone connected to a Cisco 831 router, select the true statement regarding Call Admission Control.()
第15题:
Cisco Unified CallManager and Cisco CRS use what interface for call control?()
第16题:
Which two statements are true about the function of CAC?()
第17题:
CAC provides guaranteed voice quality on a link.
CAC artificially limits the number of concurrent voice calls.
CAC is used to control the amount of bandwidth that is taken by a call on a link.
CAC prevents oversubscription of WAN resources that is caused by too much voice traffic.
CAC allows an unlimited number of voice calls while severely restricting,if necessary,other forms of traffic.
CAC solves voice congestion problems by using QoS to give priority to UDP traffic.

第19题:
CallManager Call Control Group
CRS CTI Route Point
CRS JTAPI User
CTI ports
CRS Call Control Group

第20题:
to eliminate the need for VoIP gateways
to scale a VoIP installation with multiple gateways
to provide call admission control and limit the number of simultaneous calls on the network
to meet the requirement to control H·323 gateways on a LAN
to accept call requests and reduce the load on the gateway
第21题:
RSVP is a required configuration to support conference calls without voice packet loss.
The QoS configuration on the 831 router must always provision sufficient bandwidth for two RTP streams.
Call admission control is an issue only when using hardware DSP resources.
When using the conference call features on a 7960 IP phone, only one RTP stream is present regardless of how many extensions are on the conference.
第22题:
grants a VoWLAN client-initiated call based on the number of active clients associated to the accesspoint
grants a VoWLAN client-initiated call based on channel bandwidth capacity
uses the 802.11i specification
uses 802.11 action frames
requires a WMM-enabled client
第23题:
the seventh call is routed via the PSTN
the call is denied and the original six (6) calls remain
the call is completed and the first call is dropped
the call is completed, but all calls have quality issues
the call is completed but the seventh call has quality issues
