Q11. Which two packet types does an RTP session consist of? (Choose two.)
An RTP session is established for each multimedia stream. A session consists of an IP address with a pair of ports for RTP and RTCP. For example, audio and video streams use separate RTP sessions, enabling a receiver to deselect a particular stream. The ports which form a session are negotiated using other protocols such as RTSP (using SDP in the setup method) and SIP. According to the specification, an RTP port should be even and the RTCP port is the next higher odd port number.
Q12. Which two Cisco IOS AAA features are available with the local database? (Choose two.)
A. command authorization
B. network access authorization
C. network accounting
D. network access authentication
Configuring the Local Database
This section describes how to manage users in the local database. You can use the local database for CLI access authentication, privileged mode authentication, command authorization, network access authentication, and VPN authentication and authorization. You cannot use the local database for network access authorization. The local database does not support accounting.

Q13. Which IP SLA operation type is enhanced by the use of the IP SLAs Responder?
C. ICMP Echo
D. UDP Echo
Figure 1. UDP Echo Operation
Response time (round-trip time) is computed by measuring the time taken between sending a UDP echo request message from Device B to the destination device--Device A--and receiving a UDP echo reply from Device A. UDP echo accuracy is enhanced by using the IP SLAs Responder at Device A, the destination Cisco device. If the destination device is a Cisco device, then IP SLAs sends a UDP datagram to any port number that you specified. Using the IP SLAs Responder is optional for a UDP echo operation when using Cisco devices. The IP SLAs Responder cannot be configured on non-Cisco devices.
Q14. DRAG DROP
Drag and drop the IPv6 multicast feature on the left to its corresponding function on the right.
Q15. Refer to the exhibit.
Which statement describes what the authoritative flag indicates?
A. Authentication was used for the mapping.
B. R1 learned about the NHRP mapping from a registration request.
C. Duplicate mapping in the NHRP cache is prevented.
D. The registration request had the same flag set.

Q20. Which two statements are characteristics of Ethernet private LAN circuits? (Choose two.)
A. They support communication between two or more customer endpoints.
B. They utilize more than one bridge domain.
C. They support point-to-multipoint EVC.
D. They support multipoint-to-multipoint EVC.
An Ethernet Private LAN (EPLAN) is a multipoint–to–multipoint EVC. EPLAN is an EVC that supports communication between two or more UNIs. In EPLAN, only one EVC can exist on a port and the port can have only one EFP.
