Gigabyte (GB)

Answer

Kilobyte (KB)

Question 3

Which of the following file attributes on a Windows system would prevent a user from accidentally modifying a document when set?

Accepted Answer

Read-only. The read-only attribute in Windows prevents a file from being modified or deleted (though it can be overridden by the user). Hidden hides the file, system marks it as a system file, and archive is used for backup.

Answer

Hidden

Answer

System

Answer

Archive

Question 4

Which THREE of the following are examples of social engineering attacks?

Accepted Answer

Tailgating. Tailgating (C) is a social engineering attack because it relies on manipulating a person's courtesy or trust to physically follow an authorized individual through a secure door or access point without presenting credentials. Phishing (D) is a social engineering attack that uses deceptive emails, messages, or websites to trick users into revealing credentials or clicking malicious links. Shoulder surfing (E) is a social engineering attack in which an attacker visually observes someone entering passwords, PINs, or other sensitive data in a public or shared space. Adware (A) is a type of unwanted software that displays advertisements and is classified as malware or a PUP, not a social engineering technique. Spoofing (B) is a technical impersonation technique, such as IP, MAC, or email spoofing, and while it can support social engineering, it is not itself an example of a social engineering attack.

Answer

Adware

Answer

Spoofing

Question 5

A user wants to connect an external monitor to their laptop. The monitor supports a resolution of 3840x2160 at 60Hz. Which of the following ports on the laptop would be BEST suited for this display?

Accepted Answer

DisplayPort. DisplayPort is the best choice because it natively supports 4K resolution at 60Hz and higher, with ample bandwidth (DisplayPort 1.2 offers 17.28 Gbps) to drive such a display without compression or chroma subsampling. It is designed specifically for high-resolution digital display connections and is standard on modern laptops and monitors. HDMI 1.4, while capable of 4K, is limited to 30Hz at that resolution, making it unsuitable for smooth 60Hz operation.

Answer

USB 3.0 Type-A

Answer

VGA

Answer

HDMI 1.4

Question 6

A network administrator is setting up a small office network with 20 computers. The network must be easy to troubleshoot and resilient to a single cable failure affecting only one device. Which topology is most appropriate?

Accepted Answer

Star. Star topology connects each device to a central switch. If one cable fails, only that device is affected, making it easy to troubleshoot. It is the most common for modern networks.

Answer

Ring

Answer

Bus

Answer

Mesh

Question 7

Which of the following best describes the function of a DNS server?

Accepted Answer

Resolves domain names to IP addresses. A DNS (Domain Name System) server translates human-readable domain names (e.g., www.example.com) into machine-readable IP addresses (e.g., 192.0.2.1). This resolution process is fundamental to network communication, as applications rely on IP addresses to locate and connect to servers. Without DNS, users would need to memorize numeric IP addresses for every website or service.

Answer

Hosts web pages

Answer

Forwards traffic between networks

Answer

Assigns IP addresses to devices

Question 8

Which THREE are valid primitive data types in most programming languages? (Choose three.)

Accepted Answer

Character. Character (B), Boolean (C), and Integer (D) are all primitive data types because they represent single, indivisible values directly supported by the language's type system: a character holds one text symbol (e.g., char in C/Java), a Boolean holds true/false, and an integer holds a whole number. These types are typically built into the language and stored as simple values rather than as composite structures. In contrast, String (A) is generally a composite or reference type (e.g., a sequence of characters, such as java.lang.String), and Array (E) is a derived/aggregate data structure that holds multiple elements, so neither qualifies as primitive.

Answer

String

Answer

Array

Question 9

A software developer is writing a script that needs to run a set of instructions repeatedly until a condition is met. Which programming construct should be used?

Accepted Answer

While loop. A while loop is the correct construct because it repeatedly executes a block of code as long as a specified condition remains true. This is ideal for scenarios where the number of iterations is not known in advance and depends on a dynamic condition, such as waiting for a file to appear or a network response.

Answer

For loop

Answer

If-else statement

Answer

Function definition

Question 10

Which TWO concerns are most critical when selecting a backup method? (Select exactly two.)

Accepted Answer

Recovery time objective. Recovery time objective (RTO) is critical because it defines the maximum acceptable downtime after a failure, directly influencing the choice of backup method (e.g., full vs. incremental) and storage medium (e.g., local disk vs. cloud). A shorter RTO requires faster restoration, often necessitating more frequent backups or technologies like snapshots or replication.

Answer

Network topology

Answer

Display resolution

Answer

Operating system version

Question 11

A technician installs a new network printer. It can communicate with other computers on the same network but no one outside the network can access it. What is the MOST likely cause?

Accepted Answer

Firewall blocking external traffic. A firewall is designed to control incoming and outgoing network traffic based on predetermined security rules. If the printer can communicate locally but not with external networks, the most likely cause is that the firewall is blocking inbound traffic from outside the local subnet, preventing external devices from reaching the printer's IP address or port.

Answer

Incorrect printer driver

Answer

No IP address configured

Answer

Faulty Ethernet cable

Question 12

A user reports that a spreadsheet application crashes every time they try to open a specific file. The file was created in a newer version of the software. What is the most likely cause?

Accepted Answer

The file was saved in a format incompatible with the installed version.. The most likely cause of a crash when opening a file created in a newer version of the software is a format incompatibility. Newer versions often use updated file formats (e.g., .xlsx vs. .xls in Excel) that older versions cannot parse correctly, leading to application instability or crashes. This is a common scenario in backward compatibility issues, where the installed software lacks the necessary codecs or schema to interpret the file's structure.

Answer

The computer does not have enough RAM.

Answer

The file is corrupted.

Answer

The user does not have permission to access the file.

Question 14

A server has four hard drives configured in RAID 5. One drive fails. What must the technician do to restore full redundancy?

Accepted Answer

Replace the failed drive and rebuild the array. RAID 5 uses distributed parity across all drives, allowing the array to tolerate a single drive failure without data loss. When a drive fails, the technician must replace the failed drive and then rebuild the array, during which the RAID controller reconstructs the missing data from the parity information on the remaining drives. This restores full redundancy by returning the array to a fault-tolerant state.

Answer

Replace all drives and reconfigure RAID

Answer

Simply replace the drive with a larger capacity drive

Answer

Replace the failed drive and restore from backup

Question 15

A graphic designer needs a component to accelerate rendering of 3D models. Which of the following computer hardware components is specifically designed for this purpose?

Accepted Answer

GPU. A GPU (Graphics Processing Unit) is purpose-built with thousands of parallel shader cores optimized for the matrix and vector math used in 3D rendering, making it the correct component to accelerate model rendering. CPUs can render 3D graphics but far more slowly because they have fewer, more general-purpose cores. RAM and SSDs affect capacity and load times, not rendering throughput.

Answer

RAM

Answer

SSD

Answer

CPU

Question 16

A user wants to upgrade their workstation's storage without losing existing data. Which of the following is the BEST method?

Accepted Answer

Clone the existing drive to the new one. Cloning the existing drive to the new one creates an exact bit-for-bit copy of the original drive, including the operating system, applications, settings, and all data. This allows the user to simply swap the drives and boot normally without any data loss or reinstallation. It is the most direct method that preserves the existing environment intact.

Answer

Perform a clean installation on the new drive

Answer

Back up data to external drive, then restore

Answer

Set up a RAID 1 array

Question 17
