Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Network-based automated deployment. Network-based automated deployment, is the most efficient method for deploying a custom application to 500 employees. This method allows IT to centrally distribute the software via tools like Group Policy or SCCM, ensuring consistent installation and easy updates across all machines. Manual installation (B) is time-consuming, email attachment (C) is insecure and unreliable for large numbers, and user download (D) lacks control and scalability. Network-based deployment is the standard for enterprise environments.

Answer

Manual installation via USB

Answer

Email attachment of installer

Answer

Allow users to download from website

Question 2

A technician is troubleshooting a user's inability to access the internet. The user can ping the default gateway but cannot ping external websites. What is the most likely issue?

Accepted Answer

DNS server is not configured or is unreachable. The user can ping the default gateway, which confirms that the local network configuration (IP address, subnet mask, and gateway) is correct and that Layer 3 connectivity to the router is working. However, pinging external websites fails because the DNS server is not configured or unreachable, preventing the resolution of domain names to IP addresses. This is a classic symptom: internal connectivity works, but name resolution fails.

Answer

Firewall is blocking all outbound traffic

Answer

Default gateway is down

Answer

IP address is misconfigured

Question 3

An IT manager is evaluating a cloud storage service for backup of critical company data. The manager is concerned about data security and availability. The service offers encryption at rest and in transit, 99.9% uptime SLA, and geo-redundancy. However, the service uses multi-tenancy. Which of the following is a potential concern the manager should address?

Accepted Answer

The data might be accessible by other tenants. The primary concern with multi-tenancy in a cloud storage service is the risk of data isolation failure, where a vulnerability or misconfiguration could allow one tenant to access another tenant's data. Even with strong encryption at rest and in transit, the data must be decrypted for processing, and if the hypervisor or storage layer has a flaw, other tenants could potentially read the decrypted data. This is a well-known security risk in shared infrastructure models like IaaS and PaaS.

Answer

The uptime SLA is not sufficient

Answer

The encryption might slow down data transfers

Answer

The geo-redundancy might cause latency

Question 4

A user notices their computer is running slowly and has many applications open. Which TWO hardware components are most likely to impact the speed at which multiple applications can run simultaneously? (Select TWO).

Accepted Answer

Amount of RAM. Option B (Amount of RAM) is correct because running many applications simultaneously requires enough physical memory to hold each process's working set; when RAM is exhausted, Windows pages data to disk via the pagefile, causing severe slowdowns, so more RAM directly allows more concurrent applications to stay resident in memory. Option E (CPU speed and cores) is correct because the processor executes the instructions for all running applications, and more cores plus higher clock speed let the CPU schedule and execute multiple threads/processes in parallel rather than time-slicing a single core, which is exactly what determines multitasking throughput. Option A (SSD vs HDD) affects storage read/write latency and boot or load times, but it is not the primary factor for keeping many already-running applications responsive. Option C (Hard drive capacity) only concerns how much data can be stored, not how fast multiple apps run. Option D (GPU memory) mainly affects graphics rendering, gaming, and GPU-accelerated workloads, not general multitasking of ordinary applications.

Answer

SSD vs HDD

Answer

Hard drive capacity

Answer

GPU memory

Question 5

A technician is setting up a virtual machine on a laptop running Windows 10. The technician installs VirtualBox and creates a Linux VM. Which type of hypervisor is VirtualBox?

Accepted Answer

Type 2 hypervisor. VirtualBox is a Type 2 hypervisor because it installs as an application on top of an existing host operating system (Windows 10) and relies on that OS for hardware access and scheduling. It does not run directly on the bare metal like ESXi or Hyper-V. This host-dependent architecture is the defining characteristic of Type 2 (hosted) hypervisors.

Answer

Bare-metal hypervisor

Answer

Type 1 hypervisor

Answer

Container

Question 6

A company is choosing a storage solution for archival data that is rarely accessed. Which TWO characteristics are typically true of HDDs compared to SSDs? (Choose two.)

Accepted Answer

Slower access times. Option B is correct because HDDs rely on spinning magnetic platters and mechanical read/write heads, so their seek time and rotational latency make access times significantly slower than SSDs, which have no mechanical delay. Option C is correct because HDDs cost substantially less per gigabyte to manufacture and purchase, making them the economical choice for rarely accessed archival data where capacity matters more than speed. Option A is incorrect because SSDs, using NAND flash memory, deliver much faster read/write speeds than HDDs. Option D is incorrect because SSDs generally consume less power than HDDs, which must continuously spin platters and move actuator arms. Option E is incorrect because SSDs have no moving parts and are therefore more durable against shock and vibration, not HDDs.

Answer

Faster read/write speeds

Answer

Lower power consumption

Answer

More durable due to no moving parts

Question 7

Which THREE of the following are best practices for password security?

Accepted Answer

Enabling two-factor authentication where possible. Option B is correct because enabling two-factor authentication (2FA) adds a second verification factor (e.g., TOTP, hardware token, or push notification) beyond the password, so a stolen or guessed password alone is insufficient to compromise the account. Option C is correct because a password manager generates high-entropy, unique credentials for each site and stores them encrypted (typically under AES-256 with a master passphrase), eliminating weak or reused passwords and reducing the risk of credential-stuffing attacks. Option E is correct because length and character diversity increase the search space, making brute-force and dictionary attacks computationally impractical; 12+ characters mixing uppercase, lowercase, digits, and symbols aligns with NIST and common policy guidance for strong passwords. Option A is wrong because sharing passwords destroys individual accountability and non-repudiation, and violates least-privilege and audit principles; use delegated accounts or role-based access instead. Option D is wrong because reusing one password across sites means a single breach exposes all accounts via credential stuffing, so every account should have a unique password.

Answer

Sharing passwords with trusted coworkers when necessary

Answer

Reusing the same password across multiple sites

Question 8

A database includes a table called 'Products' with columns: ProductID, ProductName, Price, and Quantity. Which TWO of the following SQL statements correctly insert a new product into the table? (Select TWO.)

Accepted Answer

INSERT INTO Products (ProductID, ProductName, Price, Quantity) VALUES (1, 'Widget', 9.99, 100). Only the INSERT statements that provide values for all required columns in the correct order are valid. Option C explicitly lists columns and provides correct values. Option E omits column names but provides values for all four columns in the correct order. Option A uses an invalid syntax (SET clause is not standard SQL for INSERT). Option B provides three values but only two column names, causing a mismatch. Option D provides only three values for a four-column table.

Answer

INSERT INTO Products SET ProductID=1, ProductName='Widget'

Answer

INSERT INTO Products (ProductName, Price) VALUES ('Widget', 9.99, 100)

Answer

INSERT INTO Products VALUES (1, 'Widget', 9.99)

Question 9

Which THREE of the following are common types of computer networks? (Select three.)

Accepted Answer

LAN. A LAN (Local Area Network) connects computers within a limited geographic area, such as a home, office, or school, using Ethernet or Wi-Fi. It is one of the most fundamental network types, typically operating at Layer 2 of the OSI model with high data transfer rates and low latency.

Answer

HDMI

Answer

USB

Question 10

A user reports that their desktop computer will not power on at all. No lights appear, and no fans spin. The power cable is securely connected to the wall outlet and the power supply. Which component should the technician check first?

Accepted Answer

The power supply unit. A completely unresponsive computer with no lights or fan activity points to a power delivery problem, making the power supply unit the first component to check. RAM, hard drive, and CPU cooler issues would typically allow some signs of power or produce specific errors.

Answer

The hard drive

Answer

The CPU cooler

Answer

The RAM modules

Question 11

Refer to the exhibit. The query returns two rows. If the database had an index on the Department column only, how would the query execution be affected?

Accepted Answer

The query would run faster because the index reduces the number of rows to scan for Department.. An index on the Department column allows the database engine to quickly locate rows matching the Department condition without scanning the entire table. This reduces the number of rows that need to be evaluated for the Salary condition, speeding up the query. The index does not affect the result set—it only improves access path efficiency.

Answer

The query would return fewer rows because the index excludes the Salary condition.

Answer

The query would return more rows because the index includes both columns.

Answer

The query would fail because the index conflicts with the SELECT *.

Question 12

Which of the following is an example of something you are in multi-factor authentication?

Accepted Answer

Fingerprint scan. In multi-factor authentication, the three factor categories are something you know (password, PIN), something you have (smart card, token, phone), and something you are (biometric — fingerprint, retina, face). A fingerprint scan is a biometric, which falls under 'something you are,' making it the correct example of an 'are' factor.

Answer

Password

Answer

Smart card

Answer

One-time passcode

Question 13

A small accounting office uses three desktop computers running Windows 10. One computer has become extremely slow over the past week. The user reports that the computer takes a long time to start up and applications are unresponsive. The technician checks Task Manager and sees that physical memory usage is at 95% and the page file is heavily used. The hard drive activity light is solid. The computer has 4GB of RAM and a 1TB HDD with 200GB free. Which course of action should the technician take first to most directly address the performance issue?

Accepted Answer

Upgrade the RAM to at least 8GB. The system has only 4GB of RAM, and physical memory usage is at 95% with heavy page file utilization. This indicates the computer is thrashing — constantly swapping data between RAM and the slow HDD, causing the solid hard drive activity light and unresponsiveness. Adding more RAM (to at least 8GB) directly reduces reliance on the page file, alleviating the bottleneck and addressing the root cause of the performance issue.

Answer

Increase the page file size

Answer

Disable unnecessary startup programs

Answer

Run a full antivirus scan

Question 14

A user wants to connect an external storage drive to a laptop for fast file transfers. The laptop has USB-A, USB-C, and Thunderbolt 3 ports. Which connection provides the fastest theoretical data transfer speed?

Accepted Answer

Thunderbolt 3. Thunderbolt 3 offers a theoretical bandwidth of 40 Gbps, far exceeding USB-A 2.0 (480 Mbps), USB-A 3.0 (5 Gbps), and USB-C 3.1 (10 Gbps). For an external storage drive, Thunderbolt 3 therefore provides the fastest theoretical transfer rate among the listed options, making it the correct choice.

Answer

USB-A 2.0

Answer

USB-A 3.0

Answer

USB-C 3.1

Question 15

A user wants to upgrade their desktop's storage from a traditional hard drive to a faster drive that connects directly to the motherboard without cables. Which storage interface should they choose?

Accepted Answer

NVMe M.2. NVMe M.2 drives plug directly into an M.2 slot on the motherboard, requiring no data or power cables, and use the PCIe bus for far higher throughput than SATA. This matches the user's requirement of a fast drive that connects directly to the motherboard without cables. M.2 NVMe is the standard choice for modern desktop storage upgrades where cable-free installation and maximum speed are priorities.

Answer

External USB drive

Answer

SATA SSD

Answer

SATA hard drive
