How fast is 10baseT?
Correct Answer
C. 10Mbps
Explanation
10baseT refers to a type of Ethernet network standard that uses twisted pair cables. It has a maximum data transfer rate of 10Mbps, which means it can transmit data at a speed of 10 megabits per second. This is a relatively slower speed compared to other Ethernet standards like 100baseT or 1000baseT, which provide higher data transfer rates of 100Mbps and 1000Mbps respectively. Therefore, the correct answer is 10Mbps.
2.
How fast is 1000baseT?
Correct Answer
D. Gigabit Ethernet, 1000Mbps
Explanation
Gigabit Ethernet is the correct answer because it provides a speed of 1000Mbps. This means that it is capable of transmitting data at a rate of 1 gigabit per second, making it significantly faster than the other options listed.
3.
What distance can data over a 1000BaseT travel?

What does STP stand for?
Correct Answer
shielded twisted pair
Shielded Twisted Pair
Shielded twisted pair
Explanation
STP stands for shielded twisted pair. It is a type of cabling that is used for transmitting data signals. The cables are made up of twisted pairs of wires, which helps to reduce electromagnetic interference. The cables are also shielded, which provides additional protection against interference from external sources. Shielded twisted pair cables are commonly used in networking and telecommunications applications to ensure reliable and high-quality data transmission.
11.
What does UTP stand for?
Correct Answer
unshielded twisted pair
Unshielded twisted pair
Unshielded Twisted Pair
Explanation
UTP stands for unshielded twisted pair. This is a type of cable commonly used for Ethernet connections. It consists of multiple pairs of twisted copper wires, which helps to reduce electromagnetic interference. The term "unshielded" indicates that the cable does not have any additional shielding to protect against interference. The term "twisted pair" refers to the way the wires are twisted together, which further helps to minimize interference. Overall, UTP is a cost-effective and widely used cable for networking purposes.
12.
How many pairs of copper wires can be found in a Cat5e UTP Patch cable?
Correct Answer
4
Explanation
A Cat5e UTP Patch cable typically consists of four pairs of copper wires. Each pair is twisted together to reduce interference and improve signal quality. Therefore, the correct answer is 4.
13.
What surrounds the 4 pairs of twisted copper wires in a Cat5e STP patch cable?
Correct Answer
D. Thin Metal Shielding
Explanation
wisted pair cables are often shielded in attempt to prevent electromagnetic interference. Because the shielding is made of metal, it may also serve as a ground. However, usually a shielded or a screened twisted pair cable has a special grounding wire added called a drain wire. This shielding can be applied to individual pairs, or to the collection of pairs. When shielding is applied to the collection of pairs, this is referred to as screening. The shielding must be grounded for the shielding to work.

15.
Just how far in meters can we push data through SMF (Single Mode Fibre) at 1Gbps?
Correct Answer
1km
1 Kilometer
1 kilometer
1000 Meters
1000 meters
Explanation
Although single-mode fiber has
advantages in terms of bandwidth and
reach for longer distances (> 1 kilometer
at 1 Gb/s), multimode fiber easily
supports most distances required
for premises and enterprise networks.
In fact, multimode fiber can support
10 Gb/s transmission to 550 meters
for long backbone and even short
campus runs.
16.
What does MMF stand for?
Correct Answer
Multi Mode Fiber, Multi mode fiber , Multimode fiber , Multimode Fiber , multimode fiber
Explanation
In networking, MMF stands for Multimode Fiber. Multimode fiber is a type of optical fiber primarily used for transmitting data over shorter distances. It has a larger core diameter compared to single-mode fiber, allowing multiple modes (or paths) of light to propagate through the fiber. This makes it suitable for applications such as local area networks (LANs) and data center interconnects.
Multimode fiber is commonly used because it is more cost-effective for shorter distance applications and supports higher data rates compared to copper cables.

no
n
Explanation
The given answer "No,no,n" suggests that it is not possible to use SMF (Single Mode Fiber) to push data at 10Gps up to 200 meters. SMF typically supports longer distances, ranging from kilometers to tens of kilometers, rather than just 200 meters. Therefore, other types of fiber optic cables, such as Multi-Mode Fiber (MMF), may be more suitable for this specific requirement.
18.
How far can i push data with Multimode fibre at 10Gps?
Correct Answer
550 Meters
550 meters
550m
Explanation
In general, then, multimode fiber continues
