Q1. Refer to the exhibit.
How does the Cisco Unified Communications Manager advertise dn-block 1?
A. 4XXX and the ToDID will 0:
B. 4XXX and the ToDID will 0:1972555
C. 4XXX
D. 4XXX and the ToDID will 0:+ 1972555
E. 19725554XXX
Answer: B
Q2. Which statement about Service Advertisement Framework is true?
A. SAF requires that the EIGRP be configured on all routers, including non-SAF routers.
B. SAF requires that the EIGRP be configured only on SAF routers. Non-SAF routers act as an IP cloud.
C. SAF has no dependency on the underlying routing protocol, as long as it is a dynamic routing protocol. Static routes are not supported.
D. SAF operates on any dynamic or static IP routing configuration. SAF is totally independent of the underlying routing protocol.
Answer: D
Explanation:
Because Cisco SAF is independent of IP routing and uses underlying Cisco routing technology to distribute service advertisements in a reliable and efficient manner, Cisco SAF will run in networks over any routing protocol they may have in place such as Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Exterior Border Gateway Protocol (EBGP) over an MPLS service, or static routing (Figure 2).

Q3. 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 9971 Video IP Phone. The Cisco VCS and TMS control the Cisco TelePresence MCU, and the Cisco Jabber TelePresence for Windows.

After adding SRST functionality the SRST does not work. After reviewing the exhibits, which of the following reasons could be causing this failure?
A. Device Pool cannot be default.
B. The Cisco UCM is pointing to the wrong IPv4 address of the BR router.
C. The router does not support SRST.
D. The SRST enabled router is not configured correctly.
Answer: A
Q4. 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.

Q8. Refer to the exhibit.
Which configuration elements must match for adjacent neighbors to establish a SAF neighbor relationship?
A. the label name specified in the router eigrp command
B. the autonomous-system number specified in the service-family ipv4 autonomous-system command
C. the sf-interface configuration
D. the topology base configurations
E. the label name specified in the router eigrp command and the autonomous-system number
Answer: B
Explanation:
Incorrect Answer: A, C, D, E service-family ipv4 autonomous-system 1 enables a Cisco SAF service family for the specified autonomous system on the router Link:

Q9. 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
