1. A type of interference that occurs when cables are bundled together for long lengths is known as:
- crosstalk
- cross-interference
- bundled-interference
- crosscheck
Explanation: Crosstalk occurs when cables are bundled together for long lengths.
2. What type of Ethernet twisted-pair cable may be required when the electrical environment has strong EMI and RFI interference?
- UTP
- STP
- fiber-optic
- coaxial
Explanation: Shielded twisted-pair (STP) is used in electrical environments in which EMI and RFI are so strong that shielding is a requirement to make communication possible.
3. Which of the following is the most common type of connector used to terminate twisted-pair cabling?
- RJ-10
- RJ-11
- RJ-41
- RJ-45
Explanation: All categories of data grade UTP cable are traditionally terminated into an RJ-45 connector.
