Question 1

Which statement describes the treatment of ARP requests on the local link?

A. They must be forwarded by all routers on the local network.

B. They are received and processed by every device on the local network.

C. They are dropped by all switches on the local network.

D. They are received and processed only by the target device.

Correct answer: B

Question 2

The ARP table in a switch maps which two types of address together?

A. Layer 3 address to a Layer 2 address

B. Layer 3 address to a Layer 4 address

C. Layer 4 address to a Layer 2 address

D. Layer 2 address to a Layer 4 address

Correct answer:A

Question 3

What is a characteristic of a contention-based access method?

A. It processes more overhead than the controlled access methods do.

B. It has mechanisms to track the turns to access the media.

C. It is a nondeterministic method.

D. It scales very well under heavy media use.

Correct answer: C

Question 4

What is the purpose of the preamble in an Ethernet frame?

A. is used as a padding for data

B. is used for timing synchronization

C. is used to identify the source address

D. is used to identify the destination address

Correct answer: B

Question 5

What is the Layer 2 multicast MAC address that corresponds to the Layer 3 IPv4 multicast address 224.139.34.56?

A. 00-00-00-0B-22-38

B. 01-00-5E-0B-22-38

C. 01-5E-00-0B-22-38

D. FE-80-00-0B-22-38

E. FF-FF-FF-0B-22-38

Correct answer: B

Question 6

Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.)

A. A packet that has crossed four routers has changed the destination IP address four times.

B. Destination MAC addresses will never change in a frame that goes across seven routers.

C. Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another.

D. Destination IP addresses in a packet header remain constant along the entire path to a target host.

Every time a frame is encapsulated with a new destination MAC address, a new destination IP address is needed.

Correct answer: CD

Question 7

What are two features of ARP? (Choose two.)

A. If a host is ready to send a packet to a local destination device and it has the IP address but not the MAC address of the destination, it generates an ARP broadcast.

B. An ARP request is sent to all devices on the Ethernet LAN and contains the IP address of the destination host and its multicast MAC address.

C. When a host is encapsulating a packet into a frame, it refers to the MAC address table to determine the mapping of IP addresses to MAC addresses.

D. If no device responds to the ARP request, then the originating node will broadcast the data packet to all devices on the network segment.

E. If a device receiving an ARP request has the destination IPv4 address, it responds with an ARP reply.

Correct answer: AD

Question 8

A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in its ARP cache. How will the device obtain a destination MAC address?

It will send an ARP request for the MAC address of the destination device.

It will send an ARP request for the MAC address of the default gateway.

It will send the frame and use its own MAC address as the destination.

It will send the frame with a broadcast MAC address.

It will send a request to the DNS server for the destination MAC address.

Correct answer: B

Question 9

A network administrator is connecting two modern switches using a straight-through cable. The switches are new and have never been configured. Which three statements are correct about the final result of the connection? (Choose three.)

A. The link between the switches will work at the fastest speed that is supported by both switches.

B. The link between switches will work as full-duplex.

C. If both switches support different speeds, they will each work at their own fastest speed.

D. The auto-MDIX feature will configure the interfaces eliminating the need for a crossover cable.

E. The connection will not be possible unless the administrator changes the cable to a crossover cable.

F. The duplex capability has to be manually configured because it cannot be negotiated.

Correct answer: ABD

Question 10

A Layer 2 switch is used to switch incoming frames from a 1000BASE-T port to a port connected to a 100Base-T network. Which method of memory buffering would work best for this task?

A. port-based buffering

B. level 1 cache buffering

C. shared memory buffering

D. fixed configuration buffering

Correct answer: C
