Need answers to some cisco questions

Question 1:

What causes Electrostatic Discharge (ESD)?

a Long power lines

b Faulty electrical equipment

c An accumulation of static electricity

d An increase in atmospheric humidity Question 2:

Which of the following environmental specifications are recommended for a wiring closet ?

a Carpeted floor; tiled walls and an inward opening door

b Wooden floor; brick walls and fluorescent lighting

c Tiled floor; internal power outlets and a dropped ceiling

d Raised floor; wood covered walls and an internal light switch Question 3:

Why can problems between the hot, or live, wire and the safety ground, or earth, wire pose a hazard to the operation of your computer and network?

a They can present a shock hazard to the computer user

b They can do more damage to data signals than other types of problems

c They can produce power disturbances

d They can cause the unwanted operation of an uninterruptible power supply Question 4:

In a controlled electrical circuit, which path do electrons normally follow?

a From the positively charged source to ground

b From the negatively charged source to a positively charged source

c From the more positively charged source to the less positively charged source

d From the negatively charged source to ground Question 5:

90 m

800 m

2000 m

3000 m

stion 6:

What features should be considered when assessing a potential wiring closet?

It should be secure and situated on the first (ground) floor

It should be secure and close to the POP

It should be within 150 m of the MDF and close to an entrance

It should be an internal room and close to the electrical supply distribution Question 7:

A potential wiring closet has been identified in a building with a floor area of 930 sq. m. The distance from this closet to the furthest workstation is 127 m. How many ADDITIONAL wiring closets would need to be installed?

0

Question 8:

What is an alternative name for backbone cabling?

Horizontal cabling

Vertical cabling

Main cabling

Trunk cabling

Question 9:

What is the maximum length specified for 62.5/125µm multimode optical fiber run between the MDF and IDF?

90 m

800 m

2000 m

3000 m

Question 10:

An electrician has investigated your recent power problems and has suggested that they are caused by oscillation. What is the BEST solution to your problem?

Move the network server to another room

Replace UTP with fiber optic cable

Rewire the electrical system

Fit commercial surge suppressors

Question 11:

Which statement BEST describes the current flow in an electrical circuit with a DC source?

It is constant over time

It varies over time

It increases with time

It decreases with time Question 12:

Why are exposed metal components normally connected to the ground, or earth, pin of a power outlet?

The connection is needed to increase the resistance of the circuit to ground

If an electrical fault occurs in the equipment, the connection will reduce the chance of shock

Connecting the metal to ground makes it act like an insulator

The ground connection can act as an alternative path for controlled current flow if the neutral wire is disconnected Question 13:

Why is copper considered a good conductor of electricity?

It offers a path of least resistance to current flow

It is easily formed into wires

It is cheaper than other metals

It reduces power line noise Question 14:

What features should be considered when assessing a potential wiring closet?

It should be secure and situated on the first (ground) floor

It should be secure and close to the POP

It should be within 150 m of the MDF and close to an entrance

It should be an internal room and close to the electrical supply distribution Question 15:

What are the three components that make up an uninterruptible power supply?

A battery, inverter and battery charger

A MOV, capacitor and diode

A generator, changeover circuit and server software

A circuit breaker, fuse and battery

Question 16:

What is one of the most significant causes of oscillatory noise problems on a power circuit?

Long wiring runs

School photocopiers

Locating power cables in elevator shafts

Air conditioners cycling on and off Question 17:

What is the purpose of providing a ground, or earth, connection on a wall power outlet?

To reduce the resistance in the electrical circuit

To link the neutral wire to ground

To allow fault currents to flow to ground

To complete the circuit for normal current to flow Question 18:

Which of the following problems is caused by too high a humidity level in a wiring closet?

Signal degradation

Copper wire corrosion

Insulation failure

Power surges Question 19:

What is an alternative name for backbone cabling?

Horizontal cabling

Vertical cabling

Main cabling

Trunk cabling Question 20:

Why is fiber optic cable commonly used as a network backbone between campus buildings?

It provides a less resistive path for electrical current to flow from one building to another

It enhances the signals at the physical layer

It reduces the hazardous effects of electrical potential difference and lightning strikes

It is cheaper and easier to install than copper wire

Question 21:

An electrician has investigated your recent power problems and has suggested that they are caused by oscillation. What is the BEST solution to your problem?

Move the network server to another room

Replace UTP with fiber optic cable

Rewire the electrical system

Fit commercial surge suppressors Question 22:

What is a possible problem associated with multiple building grounds?

They are often at the same potential with respect to each other

They do not allow electrical current to flow between the buildings

Separate protective devices are needed at each building

They may present a shock hazard due to different potentials Question 23:

What is another term that can be used to describe an Intermediate Distribution Frame (IDF)?

work area (WA)

telecommunications outlet (TO)

main cross-connect (MCC)

horizontal cross-connect (HCC) Question 24:

A potential wiring closet has been identified in a building with a floor area of 930 sq. m. The distance from this closet to the furthest workstation is 127 m. How many ADDITIONAL wiring closets would need to be installed?

0

1

2

8 Question 25:

What is the ideal room temperature and relative humidity at which a wiring closet should be maintained?

21 degrees Celsius / 45 % relative humidity

21 degrees Fahrenheit / 45 % relative humidity

45 degrees Celsius / 21 % relative humidity

45 degrees Fahrenheit / 21 % relative humidity

Re: Need answers to some cisco questions

I dont think this is the forum for people to take your test for you......
