Q1. If the device pool in the phone record does not match the device pools in the matching subnet, what will the system consider the phone to be? 

A. roaming 

B. unregistered 

C. unknown 

D. new device 

Answer:

Q2. Refer to the exhibit. 

All HQ phones are configured to use HQ_MRGL and all BR phones are configured to use BR_MRGL. For the HQ phones always to use the hardware conference bridge as a first choice, which configuration should be implemented? 

A. Ensure that both the hardware and software conference bridges are listed in the HQ_MRG. Ensure that the instance ID for the hardware conference bridge is 0. 

B. Ensure that both the hardware and software conference bridges are listed in the HQ_MRG. The hardware conference bridge must be configured first. 

C. Assign the hardware conference bridge to HQ_MRG. Configure a second HQ_MRG_2 and assign the software conference bridge to it. Add both the HQ_MRG and HQ_MRG_2 to the HQ_MRGL and list the HQ_MRG first. 

D. Assign the hardware conference bridge to HQ_MRG. Configure a second HQ_MRG_2 and assign the software conference bridge to it. Configure an additional HQ_MRGL_2. Add the HQ_MRG to HQ_MRGL. Add HQ_MRG_2 to HQ_MRGL_2. The HQ_MRGL should be assigned to the HQ phones. The HQ_MRGL_2 should be assigned to the HQ device pool. 

Answer:

Q3. While operating in SRST, what is needed to route calls outside of the remote site location to the PSTN? 

A. SIP trunk 

B. CallManager route patterns 

C. translation patterns 

D. POTS dial peers 

E. VOIP dial peers 

Answer:

Explanation: 

Incorrect Answer: A, B, C, E 

in time of srst configuration on router, please configure a dial-peer so that call flow in SRST mode. 

Q4. Refer to the exhibit. 

The HQ site uses area code 650. The BR1 site uses area code 408. The long distance national code for PSTN dialing is 1. To make a long distance national call, an HQ or BR1 user dials access code 9, followed by 1, and then the 10-digit number. 

Both sites use MGCP gateways. AAR must use globalized call routing using a single route pattern. Assume that all outgoing PSTN numbers are localized at the egress gateway as shown in the exhibit. 

Which partition should be configured in the AAR CSS applied at the phones? 

A. PSTN partition 

B. LD partition 

C. The HQ AAR CSS must include a partition assigned to route pattern 91408XXXXXXX. The BR1 AAR CSS must include a partition assigned to route pattern 91650XXXXXXX. 

D. AAR CSS must contain translation pattern 9.1[2-9]XX[2-9]XXXXXX for each site that must be globalized. Otherwise the called numbers will not be localized at the egress gateway. 

Answer:

Q5. Scenario 

There are two call control systems in this item. The Cisco UCM is controlling the DX650, the Cisco Jabber for Windows Client, and the 7965 and 9971 Video IP Phones. The Cisco VCS and TMS control the Cisco TelePresence Conductor, the Cisco TelePresence MCU, and the Cisco Jabber TelePresence for Windows. 

Use the exhibits to answer the following questions. 

DNS Servers 

Device Pool 

Expressway 

ILS 

Locations 

MRA 

Speed Dial 

SIP Trunk 

Which three configuration tasks need to be completed on the router to support the registration of Cisco Jabber clients? (Choose three.) 

A. The DNS server has the wrong IP address. 

B. The internal DNS Service (SRV) records need to be updated on the DNS Server. 

C. Flush the DNS Cache on the client. 

D. The DNS AOR records are wrong. 

E. Add the appropriate DNS SRV for the Internet entries on the DNS Server. 

Answer: B,C,E 

Q6. How is the region assigned to a device such as an IP phone? 

A. Regions are assigned directly in the device configuration page. 

B. Regions can be assigned only through a device pool. 

C. Regions can be assigned either directly on the device configuration page or through the device pool. If both configurations exist, the device pool region configuration takes precedence. 

D. Regions can be assigned either directly on the device configuration page or through the device pool. If both configurations exist, the device region configuration takes precedence. 

Answer:

Q7. Which three tests can you perform to verify redundancy in the customer environment? (Choose three.) 

A. Verify that all phones are registered to a second subscriber server. 

B. Verify that media resources fail over to a secondary subscriber server when the publisher fails. 

C. Verify that Cisco Unified IP phones running SCCP go into SRST mode when the WAN connection is disconnected. 

D. Verify that HSRP is active on the Cisco Unified Communications Manager subscriber servers. 

E. Verify that the H.323 redundant connection is active. 

F. Verify that SCCP fallback is configured in Cisco Unified Communications Manager. 

Answer: A,B,C 

Q8. The relationship between a Region and a Location is that the Region codec parameter is combined with Location bandwidth when communicating with other Regions. 

A. FALSE 

B. TRUE 

Answer:

Explanation: 

Locations work in conjunction with regions to define the characteristics of a network link. Regions define the type of compression (G.711, G.722, G.723, G.729, GSM, or wideband) that is used on the link, and locations define the amount of available bandwidth for the link Link:

Q9. Which command can be used to manually send the MGCP gateway to register with the secondary Cisco Unified Communications Manager server? 

A. ccm-manager switchover-to-backup 

B. mgcp use backup 

C. ccm-manager register backup 

D. not supported 

Answer:

Q10. When you configure QoS on VCS, which settings do you apply if traffic through the VCS should be tagged with DSCP AF41? 

A. Set QoS mode to DiffServ and tag value 32. 

B. Set QoS mode to IntServ and tag value to 34. 

C. Set QoS mode to DiffServ and tag value 34. 

D. Set QoS mode to IntServ and tag value to 32. 

E. Set QoS mode to ToS and tag value to 32.
