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.
New Questions 13
Which NAT type is used to translate a single inside address to a single outside address?
A. dynamic NAT
B. NAT overload
C. PAT
D. static NAT
Answer: D
Explanation:
Network address translation (NAT) is the process ofmodifying IP addressinformation in IP packet headers while in transit across a traffic routing device.
There are two different types of NAT:
u2711 NAT
u2711 PAT

Answer: D
New Questions 15
Which two statements about late collisions are true? (Choose two.)
A. They may indicate a duplex mismatch.
B. By definition, they occur after the 512th bit of the frame has been transmitted.
C. They indicate received frames that did not pass the FCS match.
D. They are frames that exceed 1518 bytes.
E. They occur when CRC errors and interference occur on the cable.
Answer: A,B

Which option describes how a switch in rapid PVST+ mode responds to a topology change?
A. It immediately deletes dynamic MAC addresses that were learned by all ports on the switch.
B. It sets a timer to delete all MAC addresses that were learned dynamically by ports in the
same STP instance.
C. It sets a timer to delete dynamic MAC addresses that were learned by all ports on the switch.
D. It immediately deletes all MAC addresses that were learned dynamically by ports in the same STP instance.
Answer: D
Explanation:
Rapid PVST+This spanning-tree mode is the same as PVST+ except that is uses a rapid convergence based on the IEEE 802.1w standard. To provide rapid convergence, the rapid PVST+ immediately deletes dynamically learned MAC address entries on a per-port basis upon receiving a topology change. By contrast, PVST+ uses a short aging time for dynamically learned MAC address entries.
The rapid PVST+ uses the same configuration as PVST+ (except where noted), and the switch needs only minimal extra configuration. The benefit of rapid PVST+ is that you can migrate a large PVST+ install base to rapid PVST+ without having to learn the complexities of the MSTP configuration and without having to reprovision your network. In rapid-PVST+ mode, each VLAN runs its own spanning-tree instance up to the maximum supported.
