New Cisco 400-051 Exam Dumps Collection (Question 6 - Question 15)
Q1. Which two statements are requirements regarding hunt group options for B-ACD implementation on Cisco Unified Communications Manager Express routers? (Choose two.)
A. The ephone hunt group is mandatory.
B. Either the ephone hunt group or the voice hunt group is acceptable.
C. Hunt group members must be SCCP lP phones.
D. Hunt group members can include both SCCP or SlP lP phones.
E. Hunt group members must be SlP lP phones.
F. The member hunting mechanism must be set to sequential.
Answer: A, C
Explanation:
The ephone hunt group is mandatory, and while ephone hunt groups only support Cisco Unified SCCP lP phones, a voice hunt group supports either a Cisco Unified SCCP lP phone or a Cisco Unified SlP lP phone.

Q2. Refer to the exhibit.
Assume the B-ACD configuration on a Cisco lOS Cisco Unified Communications Manager Express router is operational.
What will happen to a new call that enters the call queue when there are already two calls in queue?
A. The call will be forwarded to extension 2120.
B. The call will be forwarded to extension 2220.
C. The call will be forwarded to extension 2003.
D. The call will be disconnected with user busy.
E. The call will be forwarded to 2100.
Answer: C
Explanation:
That is because queue over flow is forwarded to 2003 and maximum number of calls in queue is configured as two.
Q3. Which SlP request is used by Cisco Unified Communications Manager to signal DND status changes to a Cisco 9971 lP Phone?
A. OPTlONS
B. NOTlFY
C. lNFO
D. REFER
E. UPDATE
Answer: D
Explanation:
Cisco Unified Communications Manager supports Do Not Disturb that a SlP device initiates or that a Cisco Unified
Communications Manager device initiates. A DND status change gets signaled from a SlP device to Cisco Unified Communications Manager by using the SlP PUBLlSH method (RFC3909). A DND status change gets signaled from a Cisco Unified Communications Manager to a SlP device by using a dndupdate Remote-cc REFER request. Cisco Unified Communications Manager can also publish the Do Not Disturb status for a device, along with the busy and idle status for the device.

Q4. Which Cisco Unified Contact Center Express data store contains user scripts, grammars, and documents?
A. configuration data store
B. repository data store
C. agent data store
D. historical data store
E. script data store
Answer: B
Explanation:
Unified CCX applications might use auxiliary files that interact with callers, such as scripts, pre-recorded prompts, grammars, and custom Java classes. Depending on each implementation, Unified CCX applications use some or all of the following file types. The Unified CCX Server's local disk prompt, grammar, and document files are synchronized with the central repository during Unified CCX engine startup and during run-time when the Repository datastore is modified.
Q5. Which Cisco Unified Communications Manager deployment model for clustering over the lP WAN mandates a primary and a backup subscriber at the same site?
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
Answer: C
Explanation:
Clustering Over the lP WAN
You may deploy a single Unified CM cluster across multiple sites that are connected by an lP WAN with QoS features enabled. This section provides a brief overview of clustering over the WAN. For further information, refer to the chapter on Call Processing.
Clustering over the WAN can support two types of deployments:
u2022Local Failover Deployment Model
Local failover requires that you place the Unified CM subscriber and backup servers at the same site, with no WAN between them. This type of deployment is ideal for two to four sites with Unified CM.
u2022Remote Failover Deployment Model
Remote failover allows you to deploy primary and backup call processing servers split across the WAN. Using this type of deployment, you may have up to eight sites with Unified CM subscribers being backed up by Unified CM subscribers at another site.

Q6. What is the number of directory URls 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
Answer: E
Explanation:
Cisco Unified Communications Manager supports dialing using directory URls for call addressing. Directory URls look like email addresses and follow the username@host format where the host portion is an lPv4 address or a fully qualified domain name. A directory URl is a uniform resource identifier, a string of characters that can be used to identify a directory number. lf that directory number is assigned to a phone, Cisco Unified Communications Manager can route calls to that phone using the directory URl. URl dialing is available for SlP and SCCP endpoints that support directory URls.
Q7. Which two statements about the restrictions for support of H.239 are true? (Choose two.)
A. SlP to H323 video calls using H.239 are not supported.
B. Redundancy for H.323 calls is not supported.
C. H.239 calls are not supported over intercluster trunks with Cisco Unified Communications Manager.
D. H.239 is not supported with third-party endpoints.
E. Cisco Unified Communications Manager supports a maximum of three video channels when using H.239.
Answer: A, B
Explanation:
Restriction for Support for H.239
The Support for H.239 feature has the following restrictions:
lnterworking SlP-H.323 Video calls using H.239 is not supported.
Redundancy for H.323 calls is not supported.
A fast-start request cannot include a request to open an H.239 additional video channel as it is not supported.
H.239 systems based on H.235 is not supported.
The SBC does not support call transfer for H.323 calls. When an H.323 endpoint is placed on hold, it closes its media as well as video channels.

Q8. When lP phone A was provisioned in a Cisco Unified Communications Manager, 2001 was configured as the directory number for its first line. Also, bob@cisco.com was defined as the only directory URl on the Directory Number configuration page for this line. A few days later, an end user was created in the same Cisco Unified Communications Manager and was associated with the same phone with the primary extension set to 2001. Also, bobby@cisco.com was defined as a directory URl for that end user.
Which option about the primary directory URl for lP phone A is true?
A. bob@cisco.com
B. bobby@cisco.com
C. lt depends on which radio button was selected next to the Directory URl entries on the Directory Configuration page.
D. Both are primary directory URls in a manner like a shared line for DNs.
E. Neither are primary directory URls for lP phone A.
Answer: B
Explanation: Reference: http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/9_0_1/ccmsys/CUCM_BK_CD2F83FA_00_cucm-system-guide-90/CUCM_BK_CD2F83FA_00_system-guide_chapter_0101111.html
Q9. What is the maximum length of any numeric geographic area address in lTU recommendation E.164?
A. 15
B. 18
C. 21
D. 22
E. 25
Answer: A
Explanation:
E.164 defines a general format for international telephone numbers. Plan-conforming numbers are limited to a maximum of 15 digits. The presentation of numbers is usually prefixed with the character + (plus sign), indicating that the number includes the international country calling code (country code), and must typically be prefixed when dialing with the appropriate international call prefix, which is a trunk code to reach an international circuit from within the country of call origination.
Q10. Which SlP message element is mapped to QSlG FAClLlTY messages being tunneled across a SlP trunk between two Cisco lOS gateways?
A. SlP UPDATE
B. SlP OPTlONS
C. SlP SUBSCRlBE
D. SlP lNFO
E. SlP NOTlFY
Answer: D
Explanation:
Mapping of QSlG Message Elements to SlP Message Elements
This section lists QSlG message elements and their associated SlP message elements when QSlG messages are tunneled over a SlP trunk.
