Access Point
Repeater
Firewall
Switch

Answer 33

Switch

EXPLANATION:
A Hub provides NO Intelligence in its interconnection functions. Therefore, whatever is received on one port is repeated out every other port. This leads to many Collisions occurring on the Hub and increases the number of Rebroadcasts which can slow down the Entire Network. Replacing the Hub with a Switch will break down the Hub’s single collision domain into 24 separate Collision domains (One per port on the switch) and eliminate Collisions. This will increase overall speed of the Network. A Switch is a Network Device that receives incoming data into a Buffer, then the Destination MAC Address is compared with an Address Table so that the Data is only sent out to the Port with the corresponding MAC Address. In a Switched Network, each port is in a separate collision domain.

• Due to the lack of fiber optic cabling near the Dion Training Office, the company has decided to purchase a ground-based microwave service for their primary Internet connection. This provides the company with a 100 Mbps to 1 Gbps connection based on the service plan chosen. The tech installed a small directional antenna on the office roof and pointed it at an antenna on another building 5 miles away. Which technology is being used?

Satellite
Line of Sight
Cable Modem
HFC

Answer 53

Line of Sight

EXPLANATION:
Light of Sight (LOS) is a Wireless Connection method using ground-based microwave antennas aligned with one another. Endpoints can transmit signals to one another as long as they are unobstructed by physical objects. The antennas are mounted too the top of the building to reduce interference. LOS service is often low latency, or at least lower latency than traditional satellite internet service.

A Cable Modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fiber-coaxial radio frequency over glass and coaxial cable infrastructure. Cable modems are primarily used to deliver broadband internet access as cable internet, taking advantage of an HFC and RFoG networks high bandwidth.

Satellite systems provide far better areas of coverage that can be achieved using other technologies.

What is a tool that would allow you to easily identify a network cable that was not labeled in the wiring closet during its installation?

Cable Tester
Punchdown Tool
Multimeter
Tone Generator and Probe

Answer 59

Tone Generator and Probe (Fox and Hound)

EXPLANATION:
A Tone Generator and Toner Probe is an excellent tool that allows you to easily detect which cable goes to which port on a Patch Panel in a Wiring Closet. While you could use a Cable Tester (If both ends of the Cable were available to the tech), a Tone Generator and Probe are much more efficient at identifying cables that were not properly labeled. A Tone Generator is connected to a Wall Jack, sends a repeating signal over the Cable. The Probe can then be used to detect which cable is connected to the Wall Jack by detecting the signal being sent by the Tone Generator. The Probe needs to be near or touch the cable with the tone generator attached to identify it positively.

A Cable Tester is used to ensure a cable is properly created as patch cable (Straight Through) or a Cross Over Cable. Cable Testers provide detailed information on the physical and electrical properties of a cable.

Punchdown Tools are used to connect an ethernet cable to the back of a Patch Panel, a punchdown block or the back of a network wall jack.

Multimeter can measure the Voltage or Amperage and Resistance of a Circuit. A Multimeter can be a hand-held device useful for basic fault finding and field service work or a bench instrument that can measure electricity with a High degree of accuracy.

• A Computer tech is configuring a NAS for a company to store their corporate data. The tech has installed x3 6TB Hard Drives operating at 7200 RPM in a RAID 5 Config. HOw much usable storage space is contained in the NAS?

6TB
18TB
12TB
3TB

Answer 65

12TB

EXPLANATION:
RAID 5 provides block-level stripping with distributed parity to provide redundancy using a minimum of 3 Disks. Since the NAS uses a RAID 5 config, it is a stripped array with parity. The 3 6TB HDDs are installed, but 33% of the storage capacity will store the parity information. This leaves only 12 TB of usable storage space in the NAS when using the RAID 5 Config.

Question 77

• The large multi-function printer in your office is shared between 12 people. Unfortunately, it has stopped working, and the Techs have determined it must be replaced. A New Printer has been ordered, but it will be 2 weeks until it arrives. The only other printer available in your office is the manager’s printer, but it is connected via USB to their Workstation. ONe of the Techs would like to share the Manager’s printer with the other 12 Employees for the next 2 weeks as a temporary workaround. Unfortunately, there is no space wired network jacks available in the office to connect the printer to the Network directly, but there is a Wireless Access point nearby. Which of the following is the BEST way for the Tech to allow the 12 employees to access the manager’s printer?

Configure a New Printer on each user’s workstation and point it to the Manager’s IP Address.
Share the Printer Directly from the Manager’s Computer by Creating a Share and giving the other employees access to the Share.
Purchase a Portable Wireless Print Server and Connect the Printer to it using a USB
Provide a USB thumb drive to each employee so they can transfer their files to the manager’s computer for direct printing.

Answer 77

Purchase a Portable Wireless Print Server and Connect the Printer to it using a USB.

EXPLANATION:
The BEST solution would be to use a wireless print server to connect the printer to it using USB. This wireless print server can then receive the print jobs directly from all of the network users.

It is not recommended that the technician create a share on the manager’s computer or set the printer configuration to the manager’s IP address since all print jobs would fail anytime the manager shut down or restarted their computer.

Using a USB drive to transfer the files to the manager’s computer each time someone wanted to print is also not a good solution since this is difficult for the users and will be disrupting the manager’s work every time someone needed to print something.
