   A user submits a help desk ticket regarding a smartphone that will no longer accept its charging cable. The assigned technician notices the phone does not have a protective case, and the user constantly transports the phone in a pocket. The technician attempts to use a secondary charger, but the cable falls out of the phone. Which of the following is the MOST likely cause of the issue?

   • AThe phone requires a firmware update to address charging issues.
   • BThe charge port contains foreign objects, such as lint.
   • CThe phone's battery has swelled, preventing the utilization of the charge port.
   • DThe phone has experienced water damage, thus the battery is not charging.

   Show answer

   Answer: B

   Explanation

   The MOST likely cause of the issue is that the charge port contains foreign objects, such as lint. This can cause the cable to fall out of the phone or not make a secure connection, resulting in a failure to charge. The fact that the phone is not protected by a case and is constantly transported in a pocket increases the risk of lint or other debris getting into the charge port. In this case, the technician should clean the charge port and try charging the phone again to see if the issue is resolved.

   A company in a large building uses a wireless network for its workstations. After a new company moves into the building on the floor below the old company’s wireless network begins experiencing connectivity issues. Which of the following is the most likely cause?

   • AExternal interference
   • BPort flapping
   • CHigh latency
   • DLimited connectivity

   Show answer

   Answer: A

   Explanation

   The most likely cause of the old company’s wireless network experiencing connectivity issues after the new company moves in on the floor below is interference. When a new company sets up its own wireless network, it can lead to channel interference with the existing network. The increased number of devices and radio signals in close proximity can disrupt the original network’s performance, resulting in slow throughput and dropped connections123. To address this, the old company should consider adjusting their Wi-Fi channels or exploring other solutions to mitigate interference and improve network stability.

   A systems administrator is working to ensure access to corporate laptops is limited to authorized users. The administrator has already implemented a password policy. Which of the following would be the best option to help the administrator secure the corporate resources?

   • ATrusted Platform Module
   • BBiometric scanner
   • CLaptop lock
   • DEncryption

   Show answer

   Answer: B

   Explanation

   A systems administrator is working to ensure access to corporate laptops is limited to authorized users. The administrator has already implemented a password policy. Which of the following would be the best option to help the administrator secure the corporate resources? I think it is best to answer the question as it is. Sys admin is working to "ensure limited to authorized users." so this question topic seem like it asking authentication. Since Sys admin added a password policy, Biometric scanner will improved security thus MFA. Yes encryption will help secured the company resources but threat actor was about to just able to log in your account. Encryption won't really do much if they have control access to admin account. Not sure who in CompTIA wrote these question because all the question I been reading are very confusing and not clear.

   A technician is troubleshooting connectivity issues and needs to promiscuously route a copy of traffic to a separate machine for analysis. Which of the following physical tools would best accomplish this task?

   • AToner probe
   • BWi-Fi analyzer
   • CNetwork tap
   • DLoopback plug

   Show answer

   Answer: C

   Explanation

   The correct answer is C. Network tap. A network tap is a hardware device that allows you to monitor network traffic without disrupting the network. It intercepts a copy of the network traffic and sends it to a monitoring device, such as a computer running a packet capture tool like Wireshark. This allows the technician to analyze the network traffic in detail and identify any potential issues. GG

   Which of the following is an advantage that OLED displays have over LCD displays?

   • AThe color does not degrade over time.
   • BThe power consumption is lower.
   • CThe power contrast results in finer grayscale levels.
   • DA backlight is utilized.

   Show answer

   Answer: B

   Explanation

   ChatGPT 4 answer: Option A, stating "The color does not degrade over time" for OLED displays, is not the correct answer. OLED (Organic Light-Emitting Diode) technology is known for many advantages, such as high contrast ratios, deep blacks, and energy efficiency, but color degradation over time is a known issue with OLEDs. OLED displays use organic materials that emit light when an electric current is applied. These organic materials can degrade with usage, leading to issues like burn-in and color imbalance. Over time, this can result in some colors becoming less vibrant or accurate compared to when the display was new. While modern OLEDs have made strides in longevity and durability, and many users may not notice significant degradation for several years, it is still a characteristic of the technology as of my last update in April 2023. Therefore, it would be inaccurate to claim that OLED displays do not suffer from color degradation over time. The more correct advantage of OLED over LCD, from the given options, is the lower power consumption (Option B).

   • CThe projector is overheating and needs to be cleaned
   • DThe outlet that the projector is plugged into is faulty

   Show answer

   Answer: C

   Explanation

   The projector is overheating and needs to be cleaned. Projectors can overheat if their cooling system (like fans or vents) is clogged with dust or if the environment is too hot. When a projector overheats, it will shut down automatically to prevent damage and may need some time to cool down before it can be turned on again. Cleaning the projector and ensuring proper ventilation could resolve the issue.

   A user frequently edits large files and saves them locally on a laptop. The user has recently begun experiencing performance issues and needs a cost-effective hardware upgrade. Which of the following the best way to meet the user's requirements?

   • AUpgrade the memory.
   • BUpgrade to a larger GPU.
   • CUpgrade to an SSD.
   • DUpgrade to a faster CPU.

   Show answer

   Answer: C

   Explanation

   Upgrading to an SSD (Solid State Drive) is the best way to meet the user’s requirements because it will improve the performance and storage capacity of the laptop. SSDs are faster than HDDs (Hard Disk Drives) because they have no moving parts and can access data more quickly. SSDs also have lower power consumption, lower heat generation, and higher reliability than HDDs. Therefore, upgrading to an SSD will make the laptop more responsive, boot faster, and handle large files better. According to some web sources, SSDs are the best hard drives for video editing because they can streamline the workflow and store masses of footage in one easy-to-access place1. SSDs are also one of the most common PC upgrades that can make a dramatic difference, especially for aging systems2. Additionally, Adobe recommends using SSDs for Premiere Pro and After Effects because they can handle large media files and cache data more efficiently3
