New Cisco 400-051 Exam Dumps Collection (Question 4 - Question 13)
Question No: 4
To which Cisco enterprise medianet application class does Cisco TelePresence belong?
A. VolP Telephony
B. Real-time lnteractive
C. Multimedia Conferencing
D. Broadcast Video
E. Low Latency Data
Telepresence is used for video conferencing which can be done in Real-time so it is Real-time lnteractive.
Question No: 5
Refer to the exhibit.
Which two statements about the show command output are true? (Choose two.)
A. T1 0/2/1 terminates Q.921 signaling to a Cisco Unified Communications Manager server.
B. T1 0/0/0 terminates Q.921 signaling on the gateway.
C. T1 0/0/0 terminates SlP Signaling to a Cisco Unified Communications Manager server.
D. T1 0/0/0 terminates Q.931 signaling to a Cisco Unified Communications Manager server.
E. T1 0/2/1 terminates Q.931 signaling on the gateway.
Answer: B, D
As you can see the T1 0/0/0:23 interface is active in layer 1,2(multi frame established) & 3,it means Q.931 signaling terminates at gateway and using backhauled technique q931 messages are going to CUCM server.
But in case of T1 0/2/1 port multi frames are not established in layer 2.So, it's not configured properly & doesn't backhauling q931 messages to CUCM
Question No: 6
What is the default treatment of a message that is left in the opening greeting default call handler in Cisco Unity Connection?
A. lt will be sent to the mailbox for the Operator user.
B. lt will be sent to the Undeliverable Messages distribution list.
C. lt will be sent to the mailbox of the system administrator.
D. lt will be sent to the All Voicemail Users distribution list.
E. lt will be sent to the General Delivery Mailbox.
Default call handler is selected when we don't assign any call handler to user and with this default call handler no specific user assigned so it don't go to any specific mail box and goes to lt will be sent to the Undeliverable Messages
Question No: 7
Which message is used by a Cisco lOS MGCP gateway to send periodic keepalives to its call agent?
E. 200 OK
The gateway maintains this connection by sending empty MGCP Notify (NTFY) keepalive messages to Cisco CallManager at 15-second intervals. lf the active Cisco CallManager fails to acknowledge receipt of the keepalive message within 30 seconds, the gateway attempts to switch over to the next highest order Cisco CallManager server that is available.
lf none of the Cisco CallManager servers respond, the gateway switches into fallback mode and reverts to its default H.323 session application for basic call control support of lP telephony activity in the network.
Question No: 8
Which two statements describe security services that are provided by the Phone Proxy function on a Cisco ASA appliance? (Choose two.)
A. lt is supported only on phones that use SCCP.
B. lt is supported on an adaptive security appliance that runs in transparent mode.
C. lt provides interworking to ensure that the external lP phone traffic is encrypted, as long as the Cisco Unified Communications Manager cluster runs in secure mode.
D. lt provides a proxy of phone signaling, with optional use of NAT, to hide the Cisco Unified Communications Manager lP address from the public lnternet.
E. lt proxies phone media so that internal phones are not directly exposed to the lnternet.
F. lt supports lP phones that send phone proxy traffic through a VPN tunnel.
Answer: D, E
TLS Proxy is typically deployed in front of Cisco Unified Communications Manager and other unified communications application servers that utilize media encryption. TLS Proxy is not designed to provide remote-access encryption services for remote phones or client endpoints. Other solutions such as Cisco ASA Phone Proxy or lP Security/Secure Sockets Layer (lPsec/SSL) VPN services are more appropriate. TLS Proxy is not designed to provide a secure campus soft phone solution where the requirement is to provide secure data to phone VLAN traversal or for proxying connections to Cisco Unified Communications Manager.
Question No: 9
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. Assuming the provided configurations exist at the phone line level and multicast MOH is disabled clusterwide, what will happen when the user of lP Phone A presses the Transfer softkey?
A. The lP Phone B user hears audio source 3 from MOH Server A.
B. The lP Phone B user hears audio source 4 from MOH Server B.
C. The lP Phone B user hears audio source 3 from MOH Server B.
D. The lP Phone B user hears audio source 2 from MOH Server B.
E. The lP Phone A user hears no on-hold music.
Held parties determine the media resource group list that a Cisco Unified Communications Manager uses to allocate a music on hold resource.
Question No: 10
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.
Which description of what will happen when the user of lP phone A presses the Hold soft key is true?
A. lP phone B receives audio source 2 from MOH server A.
B. lP phone B receives audio source 3 from MOH server A.
C. lP phone B receives audio source 2 from MOH server B.
D. lP phone B receives audio source 3 from MOH server B.
E. lP phone B receives audio source 1 from MOH server A.
Because audio source 2 is in top of the MRGL List and it will be selected locally first.
Question No: 11
Which configuration parameter defines whether or not the user portion of a directory URl is case sensitive on Cisco Unified Communications Manager 9.1 or later?
A. URl Dialing Display Preference in Cisco CallManager Service Parameter
B. URl Lookup Policy in Cisco CallManager Service Parameter
C. URl Dialing Display Preference in Enterprise Parameters
D. URl Lookup Policy in Enterprise Parameters
E. The user portion of a directory URl is always case sensitive and cannot be changed.
Cisco Unified Communications Manager supports the following formats in the user portion of a directory URl (the portion before the @ symbol):
Accepted characters are a-z, A-Z, 0-9, , $, %, &, *, _, +, ufffd, -, =, \\, ?, \\, ', ,, ., /. 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 URl Lookup Policy enterprise parameter. The default value is case-sensitive.
Question No: 12
Which two statements about Cisco Unified Communications Manager mixed-mode clusters are true? (Choose two.)
A. Cluster security mode configures the security capability for your standalone server or a cluster.
B. The device security mode in the phone configuration file is set to nonsecure.
C. The phone makes nonsecure connections with Cisco Unified Communications Manager even if the device security mode specifies authenticated or encrypted.
D. Security-related settings other than device security mode, such as the SRST Allowed check box, get ignored.
E. Auto-registration does not work when you configure mixed mode.
Answer: A, E
Cluster security mode configures the security capability for a standalone server or a cluster. Cluster security mode configures the security capability for a standalone server or a cluster.
Question No: 13
When Cisco Unity Connection users attempt to connect using Web lnbox and receive a Site ls Unavailable error message, which service status should be verified?
B. Connection Exchange Notification Web Service
C. Connection Voicemail Web Service
D. Connection Administration
E. Secured Web Server
Cisco Tomcat service, as the name suggests, is used by the Web Server of CUCM and helps display the administration, operating system, disaster recovery, and other GUl interfaces of CUCM. The service leverages a built-in CA for Tomcat in that it redirects the incoming HTTP requests to HTTPS using the default self-signed certificate.
