NEW QUESTION # 199
A technician is troubleshooting a PC that has been experiencing random system crashes. The technician has already checked the hard drive and the RAM, and both were in good working order. Which of the following steps should the technician take next to troubleshoot the system crashes?
- A. Test the fan speed.
- B. Disable the USB ports
- C. Decrease the RAM timings.
- D. Replace the PSU
Answer: D
Explanation:
Explanation
A PSU (power supply unit) is a component that converts the AC power from the wall outlet into DC power that the PC components can use. A faulty or failing PSU can cause random system crashes, as well as other problems such as noise, overheating, or no power at all. A PSU can fail due to various reasons, such as age, dust, power surges, or poor quality.
To troubleshoot a PSU, the technician can use a multimeter to measure the voltage output of the PSU connectors. The voltage should be within the acceptable range of the specifications. For example, the 12V rail should be between 11.4V and 12.6V. If the voltage is too low or too high, the PSU is likely defective and needs to be replaced.
Alternatively, the technician can try swapping the PSU with a known good one and see if the system crashes persist. If the system works fine with a different PSU, then the original PSU is the problem and should be replaced.
The other options are not likely to fix the random system crashes. Testing the fan speed may help to diagnose overheating issues, but it is not related to the PSU. Disabling the USB ports may help to eliminate potential conflicts with USB devices, but it is not related to the PSU. Decreasing the RAM timings may help to improve performance and stability, but it is not related to the PSU.

NEW QUESTION # 201
A technician is receiving reports that the entire office sporadically loses network connectivity throughout the day. The technician determines the root cause to be EMI. Which of the following cable mediums would be the MOST cost effective without sacrificing system performance?
- A. Shielded Cat 6
- B. Plenum Cat 5e
- C. Multimode fiber
- D. Coaxial
Answer: A
Explanation:
In this situation, the MOST cost-effective cable medium that would not sacrifice system performance would be B.
Shielded Cat 6. Electromagnetic interference (EMI) can disrupt network connectivity by interfering with the signals transmitted over network cables. Shielded Cat 6 cables are designed to provide protection against EMI by incorporating a layer of shielding material around the cable's conductors. This shielding helps to prevent EMI from interfering with the signals transmitted over the cable.
NEW QUESTION # 202

NEW QUESTION # 206
A network technician is working to locate an end user's Cat 6 cable within a network rack. The server rack is poorly documented, and a cable management system has not been implemented_ Which of the following would be the best tool to best identify the correct cable?
- A. Network tap
- B. Cable tester
- C. Loopback plug
- D. Toner probe
Answer: D
Explanation:
Explanation
The best tool to identify the correct cable is C. Toner probe.
A toner probe is a device that can be used to locate and trace a specific cable within a network rack or a wall outlet. A toner probe consists of two parts: a tone generator and a tone detector. The tone generator is connected to one end of the cable and sends an audible signal through the cable. The tone detector is used to scan the other end of the cable and pick up the signal. The tone detector emits a sound or a light when it detects the signal, indicating the correct cable.
A toner probe can be useful for network technicians who need to locate an end user's Cat 6 cable within a network rack that is poorly documented and has no cable management system. A Cat 6 cable is a type of twisted pair cable that can support high-speed data transmission over Ethernet networks. A network rack is a frame that holds network equipment, such as servers, switches, routers, or patch panels. A cable management system is a set of devices or methods that organize and secure the cables within a network rack .
The other options are not the best tools to identify the correct cable, because they have different purposes or limitations. A cable tester (option A) is a device that can be used to test the functionality and quality of a cable, such as its continuity, resistance, or interference. A cable tester can help diagnose and troubleshoot faulty cables, but it cannot locate or trace specific cables within a network rack. A network tap (option B) is a device that can be used to monitor and analyze the traffic and data that pass through a network. A network tap can help capture and inspect network packets, but it cannot locate or trace specific cables within a network rack. A loopback plug (option D) is a device that can be used to test the functionality and connectivity of a port or an interface. A loopback plug can help verify if a port or an interface is working properly, but it cannot locate or trace specific cables within a network rack.

NEW QUESTION # 207
Which of the following is an advantage that OLED displays have over LCD displays?
- A. The color does not degrade over time.
- B. The power consumption is lower.
- C. A backlight is utilized.
- D. The power contrast results in finer grayscale levels.
Answer: B
Explanation:
OLED (Organic Light Emitting Diode) displays have lower power consumption than LCD (Liquid Crystal Display) displays because they do not require a backlight to produce light. Each pixel in an OLED display can emit its own light, which also allows for higher contrast and finer grayscale levels. However, OLED displays are more prone to color degradation over time than LCD displays, which use filters to create colors.

- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
SMTP (Simple Mail Transfer Protocol) uses port 25 to send email messages between servers12.
SMTP uses port 25 to send email messages between mail servers. Therefore, the system administrator should enable port 25 to allow SMTP traffic through the host-based firewall. Reference: CompTIA A+ Certification Study Guide, Tenth Edition, pg. 282
