1. 1In the Cisco Collaboration CSR 14 on-premises Preferred Architecture, how are call-processing subscribers deployed for scalability and redundancy?

   1. A. As isolated single nodes in separate clusters
   2. B. As pairs within the Unified CM cluster
   3. C. As read-only replicas without call processing
   4. D. As extra publishers within the same cluster

   Answer: B

   Explanation: Cisco recommends "subscribers in pairs" for scaling and redundancy.

2. 2Which services must run for CUCM Release 15 IVR-based self-provisioning?

   1. A. Cisco TFTP and Cisco CAR Scheduler
   2. B. Self-Provisioning IVR and Cisco CTI Manager
   3. C. Cisco DirSync and Cisco AXL Web Service
   4. D. Cisco WebDialer and Cisco Extension Mobility

   Answer: B

   Explanation: Cisco requires "Self-Provisioning IVR and CTI Manager services" for this deployment.

3. 3What happens after CUCM applies a matching translation pattern to dialed digits?

   1. A. It forwards directly to a gateway without another digit lookup.
   2. B. It reroutes the translated digits using the pattern's CSS.
   3. C. It reroutes translated digits using only the original CSS.
   4. D. It reroutes the original digits while ignoring the translation.

   Answer: B

   Explanation: CUCM "routes the call again" using the translation pattern's calling search space.

4. 4A SIP dial peer must relay DTMF as RFC 2833 named telephone events in RTP. Which configuration selects that method?

   1. A. dtmf-relay sip-notify
   2. B. dtmf-relay sip-kpml
   3. C. dtmf-relay rtp-nte
   4. D. dtmf-relay sip-info

   Answer: C

   Explanation: The DTMF guide identifies "rtp-nte" as the RFC 2833 RTP event mechanism.

5. 5Which application delivers the Webex Suite's calling, meetings, and messaging collaboration modes to users?

   1. A. Webex Meetings
   2. B. Webex App
   3. C. Cisco Jabber
   4. D. Webex Webinars

   Answer: B

   Explanation: Cisco describes Suite modes as "delivered through the Webex App".

6. 6A SIP call establishes over TCP, but neither endpoint receives audio. Captures show RTP sent by both endpoints, and the intervening firewall permits SIP TCP traffic only. Which firewall change addresses media delivery?

   1. A. Permit only SIP signaling over UDP port 5060.
   2. B. Permit only RTCP control packets while continuing to block RTP.
   3. C. Permit the negotiated RTP UDP flows in both directions.
   4. D. Permit more TCP signaling ports while continuing to block UDP.

   Answer: C

   Explanation: Cisco notes that voice "might be blocked while the signaling carried over TCP is passed." The capture and policy identify a media filtering fault. Jitter buffering and SIP timers cannot deliver UDP packets that the firewall drops.

7. 7Which connection does the CSR 14 Preferred Architecture recommend between separate Unified CM clusters?

   1. A. LDAP connections
   2. B. TFTP connections
   3. C. SIP trunks
   4. D. SAML bindings

   Answer: C

   Explanation: Cisco says "Configure SIP trunks" to interconnect clusters.

8. 8Which CUCM configuration objects supply phone and line settings when a user self-provisions a phone?

   1. A. Route lists and route groups
   2. B. SIP profiles and SIP trunks
   3. C. Universal device and universal line templates
   4. D. Conference bridges and media resource groups

   Answer: C

   Explanation: Self-provisioning applies "universal line template and universal device template" configurations associated with the user profile.

9. 9In CUCM's three-tier routing model, which object matches the external dial string and directs the call to a gateway or route list?

   1. A. Route pattern
   2. B. Route group
   3. C. Device pool
   4. D. Line group

   Answer: A

   Explanation: The route-pattern entry matches the "external dial string".

10. 10CUBE converts incoming RTP-NTE digits to an out-of-band DTMF method on the outgoing leg. Which inbound setting prevents the receiver from processing duplicate RTP and out-of-band digits?

    1. A. dtmf-relay rtp-nte digit-drop
    2. B. dtmf-relay rtp-nte
    3. C. dtmf-relay sip-info
    4. D. dtmf-relay sip-kpml

    Answer: A

    Explanation: Cisco prescribes "dtmf-relay rtp-nte digit-drop" on the incoming leg to suppress the original NTE packets.
