What addresses are mapped by ARP?

• •destination MAC address to a destination IPv4 addres

• •destination IPv4 address to the source MAC address

• •destination IPv4 address to the destination host name

• •destination MAC address to the source IPv4 address

Refer to the exhibit.

If host A sends an IP packet to host B,

what will the destination address be in the frame

when it leaves host A?

• •DD:DD:DD:DD:DD:DD

• •172.168.10.99

• •CC:CC:CC:CC:CC:CC

• •BB:BB:BB:BB:BB:BB

• •172.168.10.65

What are two examples of the cut-through switching method? (Choose two.)

• •store-and-forward switching

• •CRC switching

• •fragment-free switching

• •QOS switching

• •fast-forward switching

What are two actions performed by a Cisco switch? (Choose two.)

• •building a routing table that is based on the first IP address in the frame header

• •using the source MAC addresses of frames to build and maintain a MAC address table

• •forwarding frames with unknown destination IP addresses to the default gateway

• •utilizing the MAC address table to forward frames via the destination MAC address

• •examining the destination MAC address to add new entries to the MAC address table

Which frame forwarding method receives the entire frame and performs a CRC check to detect errors before forwarding the frame?

• •cut-through switching

• •store-and-forward switching

• •fragment-free switching

• •fast-forward switching

What information is added during encapsulation at OSI Layer 3?

• •source and destination MAC

• •source and destination application protocol

• •source and destination port number

• •source and destination IP address

What are two services provided by the OSI network layer?

(Choose two.)

• •performing error detection

• •encapsulating PDUs from the transport layer

• •placement of frames on the media

• •collision detection

• •routing packets toward the destination

Refer to the exhibit.

The network administrator for a small advertising company has chosen to use the 192.168.5.96/27 network for internal LAN addressing. As shown in the exhibit, a static IP address is assigned to the company web server. However, the web server cannot access the Internet. The administrator verifies that

localworkstations with IP addresses that are assigned by a DHCP server can access the Internet, and the web

server is able to ping local workstations.

Which component is incorrectly configured?

• •subnet mask

• •DNS address

• •host IP address

• •default gateway address

Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?

• •to identify the broadcast address of the destination network

• •to identify the host address of the destination host

• •to identify faulty frames

• •to identify the network address of the destination network

What are two functions of NVRAM? (Choose two.)

• •to store the routing table

• •to store the startup configuration file

• •to contain the running configuration file

• •to store the ARP table

• •to retain contents when power is removed
