CompTIA Updated 220-1202 Exam Questions and Answers by rayyan

3G networks generally do not provide the bandwidth required for seamless HD video streaming. With only two signal bars and a 3G connection, the mobile device likely cannot maintain the necessary data throughput, resulting in timeouts or buffering failures. This is a classic symptom of insufficient network speed or signal strength.

A. Lack of Wi-Fi may contribute, but the root cause is the low mobile bandwidth, not the Wi-Fi state.

B. A website subscription lapse would return an account error, not a timeout.

D. Full device storage can affect downloads but not streaming from the internet.

A zero-day vulnerability demands an emergency change to quickly secure the system, even if downtime is needed.

From Mike Meyers ' Lab Manual:

“Emergency changes bypass standard scheduling to quickly address critical vulnerabilities that pose immediate risks.” .

The wrist strap is an ESD (electrostatic discharge) prevention tool used to keep the technician and the computer at the same electrical potential so static electricity doesn’t discharge into sensitive components like RAM. Quentin Docter explains that with an antistatic (ESD) wrist strap, you “attach one end to an earth ground… or the computer case and wrap the other end around your wrist. This strap grounds your body and keeps it at a zero charge.” This directly matches option C.

Mike Meyers’ Lab Manual reinforces the same concept: “The secret to avoiding ESD is to keep you and the parts of the computer you touch at the same electrical potential, otherwise known as grounding yourself to the computing device. You can accomplish this by connecting yourself to the computer via… an ESD strap.” In practical terms, RAM and CPU chips are especially ESD-sensitive, so grounding prevents intermittent or catastrophic failures that might occur after installation. Therefore, the purpose of the wrist strap is to ground electrostatic charge.

Group Policyis the standard administrative tool for setting user permissions across domain-joined systems.
