100Base-TX
10GBase-T
1000Base-T
10Base-T
Which two actions occur when a collision is detected in a CSMA/CD environment? (Select TWO)
A jam signal is sent.
Devices immediately retry without delay.
The devices use a backoff algorithm.

Which of the following is TRUE about unshielded twisted pair (UTP) cabling?
It provides strong EMI protection.
It is commonly used in LANs because it’s cost-effective.
It always requires shielding foil for installation.
It cannot support gigabit speeds.
In which environment would shielded twisted pair (STP) be a better choice than UTP?
Low-cost home office setup
High-interference industrial area
Short patch cables in a SOHO
Cloud-based networking
Which connector type is used for Ethernet networking and supports speeds up to 10 Gbps?
RJ11
RJ45

A technician needs to run cabling through an air plenum space. Which cable type is most appropriate?
Riser-rated
Plenum-rated
STP cable
Coaxial cable
Which of the following correctly matches twinaxial cable with its typical use?
Long-range television broadcast

DSL Internet connections
Analog phone lines
Which of the following is a key difference between T568A and T568B cabling standards?
T568B supports faster speeds than T568A.
They use different wire pair assignments.
T568A is for fiber and T568B is for copper.
T568B requires shielded cabling.
A technician finds intermittent connectivity on a network drop. Upon inspection, the cable is bent sharply near the wall plate. What is the MOST likely cause?
Incorrect T568B termination
Excessive attenuation from sharp bend
Incorrect use of plenum-rated cable
Damaged CSMA/CD process
