| Question ID 18513 | Which statement describes the purpose of the Payload Type field in the RTP header?
|
| Option A | It identifies the signaling protocol.
|
| Option B | It identifies the codec.
|
| Option C | It identifies the port numbers for RTP.
|
| Option D | It identifies the port numbers for RTCP.
|
| Correct Answer | B |
Explanation Explanation: PT, Payload Type. 7 bits: Identifies the format of the RTP payload and determines its interpretation by the application. A profile specifies a default static mapping of payload type codes to payload formats. Additional payload type codes may be defined dynamically through non-RTP means. An RTP sender emits a single RTP payload type at any given time; this field is not intended for multiplexing separate media streams. A full list of codecs and their payload type values can be found at the link below: Reference: http://www.networksorcery.com/enp/protocol/rtp.html
| Question ID 18514 | Refer to the exhibit.
 Which statement is true?
|
| Option A | It is impossible for the destination interface to equal the source interface.
|
| Option B | NAT on a stick is performed on interface Et0/0.
|
| Option C | There is a potential routing loop.
|
| Option D | This output represents a UDP flow or a TCP flow.
|
| Correct Answer | C |
Explanation Explanation: In this example we see that the source interface and destination interface are the same (Et0/0). Typically this is seen when there is a routing loop for the destination IP address.
