                      CompTIA A+ Certification Exam: Core 1 Sample Questions (Q402-Q407):

                      NEW QUESTION # 402
                      Which of the following display technologies is known for offering the highest contrast ratios?

                      Answer: D

                      Explanation:
                      OLED displays use self-emissive pixels that can turn off completely, producing true blacks and resulting in the highest contrast ratios among display technologies.


                      NEW QUESTION # 403
                      Which of the following is used to confirm that a physical port is working?

                      Answer: B

                      Explanation:
                      A loopback plug is a diagnostic tool used to test the functionality of a physical port (e.g., Ethernet, serial, fiber) by routing the output signals back into the input. This simulates a network connection and allows a technician to verify that the port's internal transmission and reception hardware is working correctly. If data is sent out and received back without errors, the physical port is considered functional.


                      NEW QUESTION # 404
                      A technician connects a network printer to a SOHO router. The technician configures several workstations to send print jobs to the printer's network address. After several days, users report that they are no longer able to use the printer. Which of the following should the technician use to resolve the issue and prevent it from reoccurring?

                      Answer: D

                      Explanation:
                      The printer likely received a different IP address from the router's DHCP service after a lease renewal. Assigning a static IP ensures the printer keeps the same address, preventing connectivity issues for configured workstations.


                      NEW QUESTION # 405
                      An office manager wants to block all outbound internet traffic but continue to enable all inbound traffic.
                      Which of the following should a technician configure to achieve this goal?

                      Answer: C

                      Explanation:
                      Comprehensive and Detailed Explanation From Exact Extract:
                      A firewall allows for detailed traffic control, including blocking outbound connections while allowing inbound ones. This is contrary to typical security setups, but it can be configured via advanced firewall rules.
                      Reference: CompTIA A+ Core 1 220-1201 Official Study Guide, Section: Firewall ConfigurationFirewalls can allow inbound traffic and deny outbound connections based on configured rules.


                      NEW QUESTION # 406
                      A technician investigates a faulty workstation that shuts down at random intervals. The technician starts the machine and hears an unusual grinding sound coming from inside the case. Which of the following would most likely cause the malfunction?

                      Answer: D

                      Explanation:
                      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.
