Quiz 3

Question 1

which type of transmission synchronization technique uses start and stop bits at the beginning and end of a data frame?

Answer 1

Asynchronous

There are three methods of performing synchronization: isochronous, asynchronous, and synchronous. When you are using an asynchronous technique, the data frame is encased within a start and stop bit, which lets the receiver know of its location within a traffic stream.

Question 2

What is the name that is used to reference the central primary cable distribution point in a building?

Answer 2

MDF
The main distribution frame (MDF) is the primary distribution point for the cabling in a building. Multiple intermediate distribution frames (IDFs) may exist throughout the building as smaller distribution points (that is, per floor)

Question 3

Which category of fiber optic media can carry a signal for the longest distance?

Answer 3

Single mode has a longer distance specification

Question 4

Which type of fiber-optic cabling only allows an individual light path through it?

Answer 4

Single-mode
Single-mode cabling has a very small interfiber core that only allows a single mode (path) of light between the transmitter and the receiver.

Question 5

What is a crimper?

Answer 5

A crimper can be used to attach a connector to the end of a UTP cable.

Question 6

What type of connector is often used for cable TV connections?

Answer 6

F-type
An F-connector of F-type connector is often used for cable TV connections.

Question 7

For home automation hubs, what wireless communication protocol is commonly used for home automation, creating a mesh network of appliances, thermostats, and door locks?

Answer 7

Z-Wave is a wireless communications protocol used primarily for home automation. It creates a mesh network using low-energy radio waves to communicate from appliance to appliance. Z-Wave is found in devices such as lighting control systems, security systems, thermostats, windows, locks, swimming pools, and garage door openers.

Question 8

What fiber type would you use if the requirements to be met included a SMF media type, 1Gbps bandwidth capacity, and a distance limitation of 5 km?

Answer 8

1000BASE-LX uses single-mode fiber (SMF), has a bandwidth capacity of 1Gbps, and a distance limitation of 5 km.

Question 9

Which two standards are both used as color code guides for a crossover cable?

Answer 9

TIA/EIA-568b or b standard
TIA/EIA-568a or a standard

Question 10

What is a common cable management component for terminating fiber connections?

Answer 10

A fiber distribution panel is often used in the fiber media environment for terminating media.
