A system administrator observes syslog messages being sent from a local host to a remote log server. As the outgoing syslog data passes down the host's protocol stack during encapsulation, which of the following actions occur? (Select TWO.)
- The Transport layer encapsulates the syslog payload into a segment or datagram by adding transport port headers.Answer
- The Network layer encapsulates the transport data unit into a packet by adding source and destination IP addresses.Answer
- CThe Data Link layer attaches port numbers directly to the physical bitstream while stripping the IP header.
- DThe Transport layer appends a Frame Check Sequence (FCS) trailer to verify physical media signals.
Answer
During outbound encapsulation, the Transport layer appends transport port headers to create a segment/datagram, and the Network layer appends IP addresses to form a packet.
Outbound encapsulation works down the protocol stack. The Transport layer adds port headers to form segments or datagrams, and the Network layer adds IP headers to form packets.
