Question 1

A technician is selecting a storage interface for a new solid-state drive that offers the fastest data transfer speeds. Which interface should they choose?

Accepted Answer

NVMe M.2. NVMe M.2 is the fastest storage interface listed because it uses the PCIe bus and the NVMe protocol, bypassing the older SATA/AHCI stack. NVMe drives deliver far higher IOPS and sequential throughput than SATA SSDs, often exceeding 3,000 MB/s versus SATA's ~550 MB/s ceiling. For a technician selecting the fastest SSD interface, NVMe M.2 is the correct choice.

Answer

Two 8 GB DDR4 modules in the same channel

Answer

One 16 GB DDR4 module

Question 5

Which of the following is an example of a lossy compression format?

Accepted Answer

JPEG. JPEG uses lossy compression, discarding perceptually less important image data (via DCT quantization) to achieve high compression ratios, which is why it is ideal for photographs but not for text or line art.

Answer

GIF

Answer

PNG

Answer

ZIP

Question 6

A programmer writes a script that automates the backup of files every night. Which type of programming paradigm is this script likely using?

Accepted Answer

Procedural programming. The script automates a fixed sequence of steps (e.g., copy files, verify integrity, log results) executed in order every night. This is the hallmark of procedural programming, which structures code as a linear series of instructions or procedures. The task does not require reacting to events, modeling objects, or avoiding side effects, making procedural the natural fit.

Answer

Event-driven programming

Answer

Object-oriented programming

Answer

Functional programming

Question 7

Which internet connection type provides symmetric upload and download speeds over a fiber-optic cable?

Accepted Answer

Fiber. Fiber-optic internet (often referred to as Fiber-to-the-Home or FTTH) uses light pulses transmitted through glass strands to deliver data. Unlike DSL or cable, fiber connections are inherently symmetric, meaning they provide identical upload and download speeds because the technology does not rely on asymmetric frequency division or shared coaxial infrastructure. This makes fiber the correct answer for symmetric speeds.

Answer

Satellite

Answer

Cable

Answer

DSL

Question 8

Which TWO of the following are appropriate steps when troubleshooting a user's inability to access the internet? (Select TWO.)

Accepted Answer

Check the IP address configuration. Checking the IP address configuration is a fundamental first step in troubleshooting network connectivity. A misconfigured IP address, such as an Automatic Private IP Addressing (APIPA) address in the 169.254.x.x range, indicates that the device failed to obtain a valid IP from a DHCP server, which would prevent internet access. Verifying the IP configuration with commands like `ipconfig` (Windows) or `ifconfig` (Linux/macOS) helps identify if the device has a proper IP, subnet mask, and default gateway.

Answer

Restart the computer

Answer

Replace the network cable

Answer

Power cycle the router

Question 9

Which TWO of the following are characteristics of a solid-state drive (SSD) compared to a hard disk drive (HDD)?

Accepted Answer

Silent operation. SSDs have no moving parts; they use NAND flash memory to store data, which eliminates the mechanical noise produced by spinning platters and moving actuator arms in HDDs. This makes SSDs completely silent during operation, a key advantage in noise-sensitive environments like recording studios or quiet office spaces.

Answer

Higher storage capacity

Answer

Lower cost per gigabyte

Answer

Sensitive to magnetic fields

Question 10

A software tester is verifying that individual functions within a module work correctly in isolation. Which type of testing is being performed?

Accepted Answer

Unit testing. Unit testing verifies individual functions or methods within a module in isolation, which matches the tester's goal of confirming that each function works correctly on its own. It is typically performed by developers using frameworks such as JUnit, NUnit, or pytest, and it precedes integration testing in the software development lifecycle. Because the question specifies 'individual functions within a module... in isolation,' unit testing is the precise match.

Answer

Integration testing

Answer

System testing

Answer

User acceptance testing

Question 11

A user receives an 'Insufficient memory' error when opening a large spreadsheet. Which hardware component is most likely insufficient?

Accepted Answer

RAM. RAM (Random Access Memory) is the primary volatile memory used to hold active data and program instructions for the CPU. When opening a large spreadsheet, the entire file must be loaded into RAM for processing. An 'Insufficient memory' error indicates that the system's RAM is too small to accommodate the spreadsheet's data, causing the operating system to fail the allocation request.

Answer

Hard drive

Answer

CPU

Answer

GPU

Question 12

A technician needs to set up a small office network with 15 computers. The computers should be able to communicate with each other and share a single internet connection. Which device is required to enable internet sharing?

Accepted Answer

Router. A router is required to enable internet sharing because it performs Network Address Translation (NAT), which allows multiple devices on a local network to share a single public IP address provided by the ISP. The router also routes traffic between the local subnet and the internet, making it the essential device for both inter-device communication and internet access.

Answer

Modem

Answer

Hub

Answer

Switch

Question 13

Which THREE of the following are effective methods to protect against malware infections? (Select THREE.)

Accepted Answer

Install and maintain antivirus software. Option B is correct because installing and maintaining antivirus software with current signature/definition databases enables detection, blocking, and removal of known malware before it can execute or spread. Option C is correct because a firewall filters inbound and outbound traffic against defined rules, blocking malicious connections, command-and-control callbacks, and unauthorized remote access that malware relies on. Option E is correct because keeping operating systems and applications patched closes known vulnerabilities (e.g., unpatched RCE flaws) that malware exploits to gain initial access or escalate privileges. Option A is wrong because opening all email attachments regardless of sender is a primary malware delivery vector, especially via phishing and malicious macros. Option D is wrong because disabling automatic software updates leaves systems exposed to publicly known exploits that vendors have already fixed.

Answer

Open all email attachments regardless of sender

Answer

Disable automatic software updates to avoid changes

Question 14

Which THREE of the following are components typically found inside a CPU?

Accepted Answer

Cache. Cache is a small, high-speed memory located directly on the CPU die that stores frequently accessed data and instructions, reducing the time needed to fetch data from main memory (RAM). It is an integral part of the CPU's architecture, typically organized in multiple levels (L1, L2, L3) to balance speed and capacity.

Answer

RAM

Answer

Hard Drive
