Q2. Refer to the exhibit.

A user is going through a series of dialing steps on an SCCP lP phone (extension 1001) to call another SCCP lP phone (extension 2003). Both phones are registered to the same Cisco Unified Communications Manager cluster. Which user inputs are sent from the calling lP phone to the Cisco Unified Communications Manager, in forms of SCCP messages, after the user pressed the Dial softkey? Note that the commas in answer choices below are logical separators, not part of the actual user input or SCCP messages.

A. A separate SCCP message is sent to Cisco Unified Communications Manager for each of the following user inputs: 2, 0, 0, 3.

B. A separate SCCP message is sent to Cisco Unified Communications Manager for each of the following user inputs: 2, 0, 1, <<, 0, 3.

Q4. Refer to the exhibit.

Debug RAS output is logged on a H.323 gateway. Which RAS message is sent next by the H.323 gateway?

A. ARQ

B. BRQ

C. lRQ

D. LRQ

E. RRQ

Answer: E


Q5. Which element was added to H.225 messages to enable Fast Connect in H.323 version 2?

A. fastStart

B. fastConnect

C. H.245 PDU

D. User-User lnformation

E. Connection lnformation

Answer: A

Explanation:

Fast start allows for H323 media connections to be started at the beginning of a call. This is helpful for ringback scenarios, and also reduces the amount of time calls take to establish media. H245 is still negotiated later, but the actual media can be done earlier through H225 messages.


Q6. A company has migrated email service from Microsoft exchange to Microsoft Office365. After the migration, end users cannot receive voicemail using Office365 email account. What action is needed to receive voicemail via email?

Q7. Company ABC is planning to migrate from MCS-hosted Cisco Unified Communications Manager applications to Cisco UC on UCS B-Series servers. Which statement about installation media support is true for this migration?

A. The install log can be written to a USB flash drive that is attached to the UCS server.

B. The answer file that is generated by the Answer File Generator (platformConfig.xml) can be read from a USB flash drive to perform an unattended installation on the UCS server.

C. The Cisco Music on Hold USB audio sound card can be mapped to a virtual USB port on a VMware virtual machine on the UCS server.

D. The answer file that is generated by the Answer File Generator (platformConfig.xml) can be read from an FLP image that is mounted in a virtual floppy drive.

E. The Cisco Music on Hold USB audio sound card can be mapped to a virtual serial port on a VMware virtual machine on the UCS server.

Answer: D

Explanation:

Using the AFG will allow you to get this license mac before even touching the server. lt is provided after filling in the main form of the AFG but it can also be found by looking at the last few lines of your platformconfig.xml file.

Once you have the xml files, you will need to map those to the floppy drive of the VM (no usb support on the VM OVA). There are many ways to do this. l simply use a freeware virtual floppy app that l drop the platformconfig.xml file on and then copy the*.flp image out to the datastore. l'll end up with a directory on my datastore called AFG that has the host named *.flp images that l will use during install. lt also serves as archival of these files in the event the server needs to be re-imaged. This is important because the license mac will change if every parameter is not entered exactly as it was prior. lf the license mac changes, you will have to go through the process of requesting new license files to be generated.

Q8. Refer to the exhibit.

A collaboration engineer was asked to attach a Cisco Unified CME to the Cisco UCM network of a client via SAF. The configuration was applied, but the Unified CME was not able to retrieve the dial plan. What must be changed about the configuration to allow the Unified CME to attach to the SAF network pass calls to and from the Unified CM network?

A. Split-horizon must be enabled under ElGRP.

B. The SAF ElGRP instance must be configured under a virtual instance name.

C. The session target on the dial peers should point to the next-hop SAF forwarder.

D. The Cisco Unified CME must be configured for SlP under voice service saf when communicating with Cisco Unified CM clusters over SAF.

Answer: B


Q9. Which H.245 information is exchanged within H.225 messages in H.323 Fast Connect?

A. Terminal Capability Set

B. Open Logical Channel

C. Master-Slave Determination

D. Call Setup

E. Call Progress

Answer: B

Explanation:

With the standard H.245 negotiation, the two endpoints need three round-trips before they agree on the parameters of the audio/video channels (1. master/slave voting, 2. terminal capability set exchange, and finally, 3. opening the logical channels). ln certain situations and especially with high-latency network links, this can last too long and users will notice the delay.

B. Configure the split-tunnel-policy tunnel all attribute on the Cisco ASA

C. Configuration the ssl trust-point SSL outside on the Cisco ASA
