TERMS & DEFINITIONS EXAM QUESTIONS Actual Qs and Ans Expert-Verified Explanation

This Exam contains:

-Guarantee passing score -100 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation

Question 1: What is the interface status when a duplex mismatch occurs?

Answer:

up/up Question 2: What happens if an interface is brought out of err-disable before the underlying issue has been resolved?

Answer:

The interface will go back into the err-disable state

Question 3: broadcast

Answer:

one-to-all communication

Question 4: Aggregation Block

Answer:

Type of distribution layer used in data center networks. Allows applications and data to be accessible.Northbound (to the core block), it works in L3.Southbound (to the access block), it works in L2.The access block connected to the aggregation block is responsible for connecting the end devices: servers and arrays.

Devices used:

-servers (high performance cpu and ram) -storage arrays (disks, redundant) -switches (robust and high performance)

Question 5: collision domain

Answer:

a location where collisions can occur

Question 6: wireless communication occurs in full or half duplex?

Answer:

half-duplex

Question 7: IPv6 bit length

Answer:

128 bits

Question 8: 1000BASE-SX max cable length

Answer:

OM1: 275 meters

OM2: 550 meters

OM3/4/5: 1000 meters

Question 9: Collapsed Architecture

Answer:

Merging of network blocks (functions) for smaller businesses/networks that don't need dedicated blocks.Question 10: what happens when one switch isn't running auto-negotiation but the other switch is?

Answer:

the switch with auto-negotiation is able to detect the appropriate speed, but the duplex setting can't be

detected. such then, the default setting is chosen:

(Cisco defaults) 10M -> half duplex 100M -> half duplex 1000M -> full duplex

Question 11: WAN Block

Answer:

Responsible for connecting multiple sites. Needs to be resilient to prevent loss of connection to remote locations. Can itself connect to remote sites or to ISPs.

Question 12: IPv6 Unique Local Unicast address

Answer:

FC00:: /7

Question 13: 1000BASE-ZX max cable length

Answer:

70 kilometers

Question 14: Three-Tier Architecture?

Answer:

Used in campus networks.

Utilizes three types of network blocks:

• Core

• Distribution

• Access

Pro: Scalable

Con: Requires more hardware and support

Question 15: what is the

trough of an RF waveform?

Answer:

bottom of the wave

Question 16: unicast

Answer:

one-to-one communication between devices

Question 17: How much dBm to add when you 10x the mW?

Answer:

+10 dBm

Question 18: late collision

Answer:

when a collision occurs after the initial 64B frame is sent. typically means a layer 1 issue.

Question 19: single-mode fiber (SMF)

Answer:

longer distances and more expensive compared to multimode smaller cores yellow jacket.

Question 20: What is the role of a Distribution Block in a network?

Answer:

Responsible for connecting access block switches to the rest of the network.

Question 21: what is the

amplitude of an RF waveform?

Answer:

height of the wave relative to the origin

Question 22: number of bits represented by one hex character

Answer:

4

Question 23: What is the interface status when a speed mismatch occurs?

Answer:

down/down

Question 24: How many non-overlapping channels are in the 5 GHz band?

Answer:

25 (could be different in other countries)
