NEW QUESTION 42
Which of these cable types transmits data the greatest distance?

• A. Cat5e
• B. Cat6
• C. Multi-mode fiber
• D. Single-mode fiber

Answer: D

Explanation:
Explanation/Reference:
When working with distances up to 2 km, use multimode optical-fiber cable.
Like multi-mode optical fibers, single mode fibers do exhibit modal dispersion resulting from multiple spatial modes but with narrower modal dispersion. Single mode fibers are therefore better at retaining the fidelity of each light pulse over longer distances than multi-mode fibers.
Incorrect:
Cat5e and Cat6 max cable length is 100 metres.

NEW QUESTION 48
One reason to replace an unmanaged switch with a managed switch is to:

• A. Manage the routing tables.
• B. Support multiple VLANS.
• C. Reduce collision domains.
• D. Route between networks,

Answer: B

Explanation:
Explanation/Reference:
A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.
The major difference between the packet switching operation of a router and that of a Layer 3 switch is the physical implementation. In general-purpose routers, packet switching takes place using software that runs on a microprocessor, whereas a Layer 3 switch performs this using dedicated application-specific integrated circuit (ASIC) hardware.

 

NEW QUESTION 49
In local area network (LAN) topologies, the primary media access methods are: (Choose two.)

• A. Negotiation
• B. Contention
• C. Kerberos
• D. Token passing

Answer: B,D

Explanation:
Explanation/Reference:
Media contention occurs when two or more network devices have data to send at the same time. Because multiple devices cannot talk on the network simultaneously, some type of method must be used to allow one device access to the network media at a time. This is done in two main ways: carrier sense multiple access collision detect (CSMA/CD) and token passing.

NEW QUESTION 53
A network device that associates a Media Access Control (MAC) address with a port is a:

• A. Switch
• B. DSL modem
• C. Router
• D. Hub

Answer: A

Explanation:
Explanation/Reference:
A switch begins learning the local MAC addresses as soon as it is connected to other devices or to a network.
This learning capability makes switches easy to use on a network.
The switch learning process works like this:
1.As a PC or other networked device sends a frame to another device through the switch, the switch captures the source MAC address of the frame and the interface that received it.
2.The switch confirms or adds the MAC address and the port to the lookup table.
