Q1. What impact do roaming-sensitive settings and Device Mobility settings have on call routing?
A. Device Mobility settings have no impact on call routing, but roaming-sensitive settings modify the AAR group, AAR CSS, and device CSS.
B. Device Mobility settings modify the device CSS and the roaming-sensitive settings modify the AAR group and AAR CSS.
C. Device Mobility settings modify the AAR group and the AAR CSS, the roaming-sensitive settings modify the device CSS.
D. Roaming-sensitive settings are settings that do not have an impact on call routing. Device Mobility settings, on the other hand, may have an impact on call routing because they modify the device CSS, AAR group, and AAR CSS.
Answer: D
Q2. Which statement about enrollment in the IP telephony PKI is true? (Source. Understanding Cisco IP Telephony Authentication and Encryption Fundamentals)
A. CAPF enrollment supports the use of authentication strings.
B. The CAPF itself has to enroll with the Cisco CTL client.
C. LSCs are issued by the Cisco CTL client or by the CAPF.
D. MICs are issued by the CAPF itself or by an external CA.
Answer: A
Explanation:
Incorrect Answer: B, C, D
The CAPF enrollment process is as follows:
1. The IP phone generates its public and private key pairs.
2. The IP phone downloads the certicate of the CAPF and uses it to establish a TLS session with the CAPF.
3. The IP phone enrolls with the CAPF, sending its identity, its public key, and an optional authentication string.
4. The CAPF issues a certicate for the IP phone signed with its private key.
5. The CAPF sends the signed certicate to the IP phone.

Q4. You are deploying a remote office setup that connects with Cisco Unity Communications Manager at a hub location. You have an available dedicated bandwidth of 20% from the 2-Mb/s WAN circuit for VoIP that supports a maximum of 17 calls. Which codec do you configure in Cisco Unity Communications Manager to achieve this?
A. G.722
B. G.711
C. G.729

Q5. Which option configures the secondary dial tone option for SRST mode to let the users hear the dial tone for PSTN calls?
A. voice service voipsecondary dialtone 0
B. call-manager-fallbacksecondary dialtone 0
C. dial-peer voice 1 potssecondary dialtone 0
D. ccm-manager secondary dialtone 0
Answer: B
Q6. 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.
How many route lists and route groups should be configured for AAR at a minimum?
A. a single route list with a local route group for each site
B. two route lists and two route groups for each site
C. a single route list and four route groups for each site
D. None. The AAR CSS can point directly to the route pattern.
Answer: A
Q7. Which command is needed to utilize local dial peers on an MGCP-controlled ISR during an SRST failover?
A. ccm-manager fallback-mgcp
B. telephony-service
C. dialplan-pattern
D. isdn overlap-receiving
E. voice-translation-rule
Answer: A
Q8. Cisco Unified Communications Manager is configured with CAC for a maximum of 10 voice calls.
Which action routes the 11th call through the PSTN?
A. Configure an SIP trunk to the ISR.
B. Configure Cisco Unified Communications Manager AAR.
C. Configure Cisco Unified Communications Manager RSVP-enabled locations.
D. Configure Cisco Unified Communications Manager locations.
Answer: B

Q10. The network administrator of Enterprise X receives reports that at peak hours, some calls between remote offices are not passing through. Investigation shows no connectivity problems. The network administrator wants to estimate the volume of calls being affected by this issue. Which two RTMT counters can give more information on this? (Choose two.)
A. CallsRingNoAnswer
B. OutOfResources
C. LocationOutOfResources
D. RequestsThrottled
E. CallsAttempted
Answer: B,C
Q11. Refer to the exhibit.
When the user of a phone registered to the Cisco Unified Communications Manager places a call to 3001 when the SAF network is down, what happens?
A. The call fails.
B. The call is rerouted to the PSTN with the constructed PSTN number as +442288223001
C. The call is rerouted to the PSTN with the constructed PSTN number as 442288223001
D. The call is rerouted to the PSTN with the constructed PSTN number as 0002288223001
E. The call is rerouted to the PSTN with the constructed PSTN number as +0002288223001
Answer: A
Explanation:
Incorrect Answer: B, C, D When the SAF forwarder loses network connection with its call-control entity, the SAF forwarder withdraws those learned patterns that were published by the call control entity. In this case, CCD requesting service marks those learned patterns as unreachable via IP, and the calls get routed through the PSTN gateway. Link:

Q12. Company A has deployed a VCS Control and is attempting to register a third-party endpoint. The engineer has confirmed that no traffic is being blocked for the endpoint and it is receiving a valid IP address. Which option could be the cause of this registration failure?
A. Third-party endpoints are not compatible with VCS Control, only with VCS Expressway.
B. Cisco Unified Communications Manager is required in addition to the VCS Control.
C. An incorrect SIP domain is configured on the VCS Control for the endpoint.
D. The VCS Control must be deployed together with VCS Expressway before endpoints can register to either one.
Answer: C
Q13. On which two call legs is the media encryption enforced in a Collaboration Edge design? (Choose two.)
A. Expressway-C to Cisco Unified Communications Manager
B. Expressway-C to Expressway-E
C. Expressway-E to outside-located endpoint
D. Expressway-E to Cisco Unified Communications Manager
E. Expressway-C to internal endpoint
Answer: B,C
Q14. 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: A
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:

Q15. What happens if location-based CAC is used and there is no bandwidth available when a remote caller is placed on hold?
A. Cisco Unified Communications Manager sends TOH rather than MOH.
B. Cisco Unified Communications Manager terminates the call.
C. Cisco Unified Communications Manager plays default MOH.
D. Cisco Unified Communications Manager attempts to reconnect the call immediately.
Answer: A
