Question #202
A technician is running a 279ft (85m) network cable between buildings that will share conduit with a large power cable.
Which of the following is the most appropriate cable for the technician to use for this project?
- A . Fiber
- B . Coaxial
- C . Cat 5e
- D . Cat 6
Correct Answer: A
A
Explanation:
In this scenario, running a network cable over a long distance (279ft or 85m) and sharing conduit with a large power cable requires careful consideration of electromagnetic interference (EMI) and the physical distance limitations of the cable type. Fiber optic cables are immune to electromagnetic interference and can support much longer distances than copper-based cables like Cat 5e or Cat 6 without signal degradation. This makes fiber optic the most appropriate choice for this project.
Reference: CompTIA A+ Core 1 Exam Objectives Section 3.1: Explain basic cable types and their connectors, features, and purposes.
CompTIA A+ Core 1 Exam Objectives Section 2.2: Compare and contrast common networking hardware.

Question #203
A technician is configuring the BIOS of a new workstation. The machine will be used for data analytics, and the technician would like to maximize the performance of the CPU.
Which of the following BIOS settings should the technician verify?
- A . Virtualization technology
- B . GPU settings
- C . BIOS update
- D . Hyperthreading
Correct Answer: D
D
Explanation:
Hyperthreading is a feature of some CPUs that allows them to execute two threads (sequences of instructions) simultaneously on each core. Hyperthreading can improve the performance of CPU-intensive tasks, such as data analytics, by increasing the utilization of CPU resources and reducing idle time. The technician should verify that hyperthreading is enabled in the BIOS settings of the workstation.

Question #204
A laptop is experiencing slow performance writing data.
Which of the following is the best component for a technician to upgrade to fix the issue?
- A . RAM
- B . HDD
- C . TPM
- D . CPU
Correct Answer: B
B
Explanation:
The best component for a technician to upgrade to fix the issue of slow performance writing data Is B. HDD. HDD stands for hard disk drive, which is a type of storage device that uses physical disks to store data. HDDs have moving parts that can slow down the read and write operations, especially when the data is fragmented or the disk is full12.
A better alternative to HDDs is SSDs, which stands for solid state drives. SSDs use flash memory and do not have any moving parts. SSDs can read and write data faster and use less power, which can improve the performance and battery life of the laptop13. Upgrading to an SSD can provide a significant improvement in performance2.
The other components are not as relevant or effective as upgrading the HDD. RAM stands for random access memory, which is a type of memory that stores temporary data for the CPU to process. RAM can affect the overall speed of the laptop, but it does not directly affect the writing performance of the storage device1. TPM stands for trusted platform module, which is a security chip that encrypts and protects data on the laptop. TPM does not affect the performance of the laptop, but rather its security1. CPU stands for central processing unit, which is the main processor of the laptop that executes instructions and calculations. CPU can affect the performance of the laptop, but it is not as easy or cost-effective to upgrade as the HDD1.

Question #205
A help desk technician is installing an SSD upgrade in a laptop. The laptop specifications call for NVMe.
Which of the following form factors should the technician most likely install in the laptop?
- A . 2.5
- B . 3.5
- C . M.2
- D . SD
Correct Answer: C
C
Explanation:
NVMe (Non-Volatile Memory Express) is an interface protocol built especially for Solid State Drives (SSDs) to utilize the high-speed PCIe bus in computers. M.2 is a form factor that is commonly used for NVMe SSDs due to its compact size and direct connection to the PCIe interface, which is ideal for laptops. The 2.5" and 3.5" form factors are more commonly associated with SATA drives, and SD is a form factor used for removable flash memory cards, not for internal storage solutions like NVMe SSDs.

Question #208
A technician upgrades a PC with two DIMMs, for a total of 32GB. After installing the two DIMMs, the user notices the OS is reporting only 16GB.
Which of the following tasks should the technician perform to resolve the issue in the most rapid, cost-effective way possible?
- A . Roll back recent system updates.
- B . Reinstall RAM in different slots.
- C . Update the OS to the latest version.
- D . Replace the faulty motherboard.
Correct Answer: B
B
Explanation:
Reinstalling RAM in different slots addresses possible issues with dual-channel configurations. If not installed correctly, the system might not recognize the full capacity. This solution is immediate and doesn’t incur extra costs, unlike replacing hardware. It reflects CompTIA A+ Core 1 exam objectives on hardware troubleshooting, specifically RAM installation and configuration.

Question #209
A user is receiving many unsolicited emails.
Which of the following controls can be configured to best reduce these types of emails?
- A . Load balancer
- B . Spam gateway
- C . Mail forwarding
- D . Proxy servers
Correct Answer: B
B
Explanation:
A spam gateway filters unsolicited emails at the server level, significantly reducing spam before it reaches user inboxes.
Why Not A (Load balancer): Load balancers distribute traffic but don’t filter spam.
Why Not C (Mail forwarding): Forwarding doesn’t filter spam.
Why Not D (Proxy servers): Proxies control web traffic, not email filtering.

Question #210
A user reports a monitor, keyboard, mouse. and headset are no longer functioning. The user has restarted the laptop and tested an alternative headset and monitor, but the issue persists. The technician notices the user has a printer. USB-C hub, and AC adapter plugged into the laptop .
Which of the following should the technician do to MOST likely resolve the issue?
- A . Verify the AC adaptor voltage.
- B . Repair the operating system.
- C . Replace the user’s USB-C hub.
- D . Reinstall the drivers for affected devices.
- E . Make sure the printer is not drawing too much power.
Correct Answer: C
C
Explanation:
The most likely cause of the issue is that the user’s USB-C hub is faulty or incompatible with the laptop. The USB-C hub is a device that allows the user to connect multiple peripherals to the laptop using a single USB-C port. If the hub is not working properly, it may prevent the monitor, keyboard, mouse, and headset from functioning. The technician should replace the user’s USB-C hub with a new one that is compatible with the laptop and test the peripherals again. Verifying the AC adapter voltage will not help with the issue, as the AC adapter is used to power the laptop, not the peripherals. Repairing the operating system will not help either, as the issue is not related to software. Reinstalling the drivers for affected devices may not help, as the issue may be caused by the hub, not the devices. Making sure the printer is not drawing too much power is irrelevant, as the printer is not connected to the hub or affecting the other peripherals.
