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:

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


Router Switching Function (

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.


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: 20

What is the effect of the overload keyword in a static NAT translation configuration?

A. It enables port address translation.

B. It enables the use of a secondary pool of IP addresses when the first pool is depleted.

C. It enables the inside interface to receive traffic.

D. It enables the outside interface to forward traffic.

Answer: A

Question No: 21

On which type of device is every port in the same collision domain?

A. a router

B. a Layer 2 switch

C. a hub

Answer: C


Collision domain

A collision domain is, as the name implies, a part of a network where packet collisions can occur. A collision occurs when two devices send a packet at the same time on the shared network segment. The packets collide and both devices must send the packets again, which reduces network efficiency. Collisions are often in a hub environment, because each port on a hub is in the same collision domain. By contrast, each port on a bridge, a switch or a router is in a separate collision domain.
