CompTIA 220-1201 Dumps Questions Answers

The combination of an unusual mechanical noise and random shutdowns strongly indicates a problem with the computer’s cooling system . A cooling fan with worn bearings, accumulated debris, or physical obstruction can produce a grinding sound.

When the CPU fan cannot rotate properly, airflow decreases and the CPU temperature rises. The computer may then shut down automatically to protect the processor and motherboard from thermal damage. Therefore, among the available answers, CPU overheating is the most likely cause of the shutdowns.

The other answers are less appropriate:

An SSD contains no moving mechanical components and would not normally produce a grinding noise.

An improperly installed graphics card is more likely to produce a blank screen, display artifacts, crashes, or failure to complete POST.

Damaged RAM commonly causes application crashes, POST errors, blue screens, freezes, or data corruption, but not a grinding sound.

CompTIA objective 5.1 associates overheating, random shutdowns, and unusual noises with motherboard, CPU, power, and RAM troubleshooting. Dell identifies fan problems as causes of noise and overheating, while SSD documentation confirms that SSDs have no moving mechanical parts.

To ensure seamless connectivity during (and after) migrating an application server, the best DNS approach in CompTIA A+ Core 1 (220-1201) terms is to use a CNAME (Canonical Name) record, which creates an alias from one hostname to another. Instead of users connecting directly to a server’s changing hostname, they connect to a consistent service name (for example, app.company.com). That name can be configured as a CNAME pointing to the current host (such as server1.company.com). When the application is moved to a new server, the technician updates what the alias ultimately resolves to (or updates the target host’s A/AAAA record), and clients continue using the same familiar application URL/name—minimizing disruption and avoiding the need to reconfigure endpoints across devices.

The other record types are not designed for this purpose. TXT records store text-based information (often verification or policy data). SPF and DKIM are email authentication-related mechanisms (typically implemented via TXT records) used to validate authorized mail senders and message integrity—not application server migration. Because the goal is maintaining a stable name for a service while the underlying host changes, CNAME is the correct record type.
