Question No: 11

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.

Question No: 12

Which statement about unicast frame forwarding on a switch is true?

A. The TCAM table stores destination MAC addresses

B. If the destination MAC address is unknown, the frame is flooded to every port that is configured in the same VLAN except on the port that it was received on.

C. The CAM table is used to determine whether traffic is permitted or denied on a switch

D. The source address is used to determine the switch port to which a frame is forwarded

Answer: B

Question No: 13

Which type of device can be replaced by the use of subinterfaces for VLAN routing?

A. Layer 2 bridge

B. Layer 2 switch

C. Layer 3 switch

D. router

Answer: C

Question No: 14

A. OSPF is distributing IPv6 routes to BGP.

B. The router is designated as an ABR.

C. The router is designated as totally stubby.

D. OSPFv3 is in use.

Answer: A

Question No: 15

Which statement about a router on a stick is true?

A. Its date plane router traffic for a single VI AN over two or more switches.

B. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs on the same subnet.

C. It requires the native VLAN to be disabled.

D. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs.

What is the default lease time for a DHCP binding?

A. 24 hours

B. 12 hours

C. 48 hours

D. 36 hours

Answer: A

Explanation: By default, each IP address assigned by a DHCP Server comes with a one- day lease, which is the amount of time that the address is valid. To change the lease value for an IP address, use the following command in DHCP pool configuration mode:
