All 220-1101 Test Inside CompTIA Questions

The CMOS battery powers the real-time clock (RTC) on the motherboard, which maintains the date and time when the computer is turned off. If the battery fails, the system will lose date and time settings, reverting to defaults on restart.

Why Not A (OS updates): While OS updates can sometimes cause time issues, they don’t typically affect changes persisting after shutdown.

Why Not C (NTP server): An incorrect NTP server setting would cause the system to synchronize incorrectly, but this issue relates to time resetting during power-off.

Why Not D (RAM): RAM is volatile memory and unrelated to storing persistent time settings.

When multiple RAM modules with different speeds are installed in a system, the system will default to the speed of the slowest module to maintain reliability and stability. In this case:

The system contains two DDR3-1066 (PC3-8500) modules and one DDR3-1333 (PC3-10600) module.

The slowest RAM speed is DDR3-1066 (PC3-8500), and the system will run all memory modules at this speed to prevent timing mismatches and data corruption.

Key Concepts:

Backward Compatibility: RAM modules with higher speeds can operate at lower speeds when mixed with slower modules.

Reliability vs. Performance: Operating all modules at the slowest speed ensures stability, especially when modules have different specifications.

The appropriate network type for this scenario is a Local Area Network (LAN), which is designed for small, localized networks, such as within a single building or room. LANs are ideal for gaming because they provide high-speed, low-latency connections.

Option A (SAN): Incorrect. A Storage Area Network is used for data storage, not for gaming or general networking.

Option B (MAN): Incorrect. A Metropolitan Area Network covers a city or campus, far exceeding the scope needed for a gaming setup in a single room.

Option D (PAN): Incorrect. A Personal Area Network is designed for a single user, such as Bluetooth devices, and would not support multiple devices connecting to a game server.

Comprehensive and Detailed Step-by-Step Explanation:

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology):

S.M.A.R.T. is a monitoring system integrated into modern HDDs and SSDs that detects and reports on various indicators of drive health and reliability.

A S.M.A.R.T. error indicates that the drive is showing signs of impending failure, even if the PC continues to boot and work normally for the time being.

Next Steps:

The appropriate action is to replace the hard drive (HDD) because a S.M.A.R.T. error is an early warning of possible hardware failure. Ignoring the warning could result in data loss if the drive fails completely.

The technician should also back up the user's data immediately to avoid losing critical information.

Incorrect Options:

B. Update the PC's BIOS: While keeping the BIOS updated is a good practice, it does not address the S.M.A.R.T. error, which is specific to the HDD.

C. Close the ticket: Closing the ticket without resolving the issue would be improper, as the S.M.A.R.T. error is a hardware problem that needs to be addressed to prevent future data loss or downtime.

D. Change the NIC: The NIC (Network Interface Card) is unrelated to the storage system and would not resolve a S.M.A.R.T. error.
