Explanation: What is that word you typed?
The stage that precedes the implementation stage of SDLC is <u>testing</u> and it involves checking the functionality of the system.
System design involves the process of determining an overall system architecture, which typically comprises the following:
- Physical processing components.
Generally, there are seven (7) main stages in the systems development life cycle (SDLC) model and these include:
1. Planning.
2. Analysis.
3. Design.
4. Development.
5. Testing.
6. Implementation.
7. Maintenance.
From the above, we can deduce that the stage which precedes the implementation stage of SDLC is testing.
During the testing stage of SDLC, a quality assurance (QA) expert checks the system to determine whether or not it is functioning properly before it is deployed for operation, which is where the system can be used.

Answer:
D - Fiber-optic Cables
Explanation:
Electromagnetic interference affects cables made from different metals and can corrupt the data running through them. However, Fiber-optic cables are constructed from glass (non-metallic) and transmit pulses of light as signals to transfer data, this means that the cables are most resistant and not susceptible to EMI.
