It is the IP address of the Router1 interface that connects the PC1 LAN to Router1

During normal operation, from which location do most Cisco switches and routers run the IOS?

flash

RAM

NVRAM

disk drive

40
What is an important function of the physical layer of the OSI model?

It encodes frames into electrical, optical, or radio wave signals.

It accepts frames from the physical media.

It encapsulates upper layer data into frames.

It defines the media access method performed by the hardware interface.

41
Which procedure is used to reduce the effect of crosstalk in copper cables?

wrapping the bundle of wires with metallic shielding

avoiding sharp bends during installation

requiring proper grounding connections

designing a cable infrastructure to avoid crosstalk interference

Twisting opposing circuit wire pairs together

42
What are the three primary functions provided by Layer 2 data encapsulation? (Choose three.)

placement and removal of frames from the media

Detection of errors through CRC calculations

conversion of bits into data signals

Delimiting groups of bits into frames

Data link layer addressing

error correction through a collision detection method

session control using port numbers

43
What method is used to manage contention-based access on a wireless network?

token passing

CSMA/CD

CSMA/CA

priority ordering

44
What happens when part of an Internet radio transmission is not delivered to the destination?

A delivery failure message is sent to the source host.

The part of the radio transmission that was lost is re-sent.

The transmission continues without the missing portion.

The entire transmission is re-sent.

45
What is the auto-MDIX feature on a switch?

the automatic configuration of full-duplex operation over a single Ethernet copper or optical cable

The automatic configuration of an interface for a straight-through or a crossover Ethernet cable connection

the ability to turn a switch interface on or off accordingly if an active connection is detected

the automatic configuration of an interface for 10/100/1000 Mb/s operation

46
Which function is provided by TCP?

Detection of missing packets

communication session control

path determination for data packets

data encapsulation

47
How does a Layer 3 switch differ from a Layer 2 switch?

A Layer 3 switch learns the MAC addresses that are associated with each of its ports. However, a Layer 2 switch does not.

A Layer 3 switch maintains an IP address table instead of a MAC address table.

A Layer 3 switch supports VLANs, but a Layer 2 switch does not.
