New Questions 9
Which feature can you use to monitor traffic on a switch by replicating it to another port or ports on the same switch?
A. copy run start
B. traceroute
C. the ICMP Echo IP SLA
D. SPAN
Answer: D
Explanation: A source port, also called a monitored port, is a switched or routed port that you monitor for network traffic analysis. In a single local SPAN session or RSPAN source session, you can monitor source port traffic, such as received (Rx), transmitted (Tx), or bidirectional (both). The switch supports any number of source ports (up to the maximum number of available ports on the switch) and any number of source VLANs.
A source port has these characteristics:
u2711 It can be any port type, such as EtherChannel, Fast Ethernet, Gigabit Ethernet, and so forth.
u2711 It can be monitored in multiple SPAN sessions.
u2711 It cannot be a destination port.
u2711 Each source port can be configured with a direction (ingress, egress, or both) to monitor. For EtherChannel sources, the monitored direction applies to all physical
ports in the group.
u2711 Source ports can be in the same or different VLANs.
u2711 For VLAN SPAN sources, all active ports in the source VLAN are included as source ports.

New Questions 16
When a router makes a routing decision for a packet that is received from one network and destined to another, which portion of the packet does if replace?
A. Layer 2 frame header and trailer
B. Layer 3 IP address
C. Layer 5 session
D. Layer 4 protocol
Answer: A
Explanation:
Router Switching Function (1.2.1.1)
A primary function of a router is to forward packets toward their destination. This is accomplished by using a switching function, which is the process used by a router to accept a packet on one interface and forward it out of another interface. A key responsibility of the switching function is to encapsulate packets in the appropriate data link frame type for the outgoing data link.
NOTE
In this context, the term u201cswitchingu201d literally means moving packets from source to destination and should not be confused with the function of a Layer 2 switch.
After the router has determined the exit interface using the path determination function, the router must encapsulate the packet into the data link frame of the outgoing interface.
What does a router do with a packet received from one network and destined for another network? The router performs the following three major steps:
u2711 Step 1.De-encapsulates the Layer 3 packet by removing the Layer 2 frame header
and trailer.
u2711 Step 2.Examines the destination IP address of the IP packet to find the best path in the routing table.
u2711 Step 3.If the router finds a path to the destination, it encapsulates the Layer 3 packet into a new Layer 2 frame and forwards the frame out the exit interface.
