Question 1

A user wants to transfer files from a smartphone to a laptop. The smartphone supports USB-C with USB 3.0, and the laptop has both USB-A and USB-C ports. Which cable type is most appropriate for maximum transfer speed?

15 minute time limit — choose an answer to begin.

Accepted Answer

USB-C to USB-C cable. A USB-C to USB-C cable is the correct choice because both endpoints support USB-C, and USB 3.0 over a native USB-C connection can negotiate the full SuperSpeed data rate without any protocol translation. Using USB-C on both ends avoids the legacy USB-A controller path and preserves the highest available bandwidth.

Answer

USB-A to USB-C cable

Answer

USB-C to Thunderbolt cable

Answer

USB-A to USB-A cable

Question 2

Which wireless standard operates on both 2.4 GHz and 5 GHz bands, providing faster speeds and better performance in crowded environments compared to its predecessor?

Accepted Answer

802.11ax. 802.11ax (Wi-Fi 6) operates on both the 2.4 GHz and 5 GHz bands and introduces OFDMA, MU-MIMO, and BSS Coloring, which significantly improve performance in dense, crowded environments compared to 802.11ac. It is the successor to 802.11ac and is designed specifically to handle high-density deployments like stadiums, offices, and campuses. 802.11ac, by contrast, operates only on 5 GHz, so it cannot be the correct answer.

Answer

802.11n

Answer

802.11g

Answer

802.11ac

Question 3

A technician is building a new desktop computer for a user who needs to edit large video files. Which type of RAM should the technician recommend for dual-channel performance?

Accepted Answer

DDR5. DDR5 is the latest generation of RAM and offers the highest bandwidth and capacity per module, making it the best choice for a new build that must handle large video files. It also supports dual-channel (and even quad-channel) configurations on modern motherboards, delivering the memory throughput needed for video editing workloads. Recommending DDR5 ensures the system is not bottlenecked by older memory technology.

Answer

DDR2

Answer

DDR4

Answer

DDR3

Question 4

A network administrator is designing a new office network and wants to use a topology that provides redundancy so that if one cable fails, communication can still occur via alternate paths. Which TWO topologies offer this redundancy? (Choose TWO.)

Accepted Answer

Hybrid topology. Option C (Hybrid topology) is correct because it combines two or more different topologies (for example, a star-bus or star-ring design), and the redundant interconnections between its constituent segments allow traffic to be rerouted through alternate paths when a single cable fails. Option D (Mesh topology) is correct because every node connects to multiple other nodes, so if one link breaks, data can travel across the remaining links via an alternate route, providing the highest level of redundancy. Option A (Ring topology) is not correct here because a simple ring relies on a single closed loop, and a single cable break can disrupt the entire ring unless a dual-ring or FDDI-style counter-rotating configuration is used, which is not what a basic ring topology provides. Option B (Star topology) is not correct because all devices connect to a central switch or hub, so a failure of that central device or a single cable to it isolates the attached node with no alternate path. Option E (Bus topology) is not correct because all nodes share one common backbone cable, and a break in that backbone can bring down the entire network segment rather than allowing alternate routing.

Answer

Ring topology

Answer

Star topology

Answer

Bus topology

Question 5

A user needs to transfer photos from a digital camera to a laptop. The camera supports wired and wireless transfer. Which THREE of the following connection methods can be used? (Choose THREE.)

Accepted Answer

USB cable. Option A (USB cable) is correct because digital cameras commonly support USB Mass Storage or PTP (Picture Transfer Protocol) over USB, allowing direct wired transfer of photos to a laptop. Option B (Bluetooth) is correct because many cameras support Bluetooth for wireless file transfer, and laptops with Bluetooth adapters can pair with the camera to receive images. Option C (SD card) is correct because the camera's SD card can be removed and inserted into the laptop's card reader (or an external reader) to copy the photos directly. Option D (NFC) is not correct because NFC is a short-range tap technology used mainly for pairing or initiating connections, not for transferring large photo files. Option E (Ethernet) is not correct because cameras generally lack Ethernet ports and the scenario describes wired/wireless transfer methods typical of USB, Bluetooth, or removable media.

Answer

NFC

Answer

Ethernet

Question 6

Which network topology connects all devices to a single central cable?

Accepted Answer

Bus. In a bus topology, all devices are connected to a single backbone cable. However, star topology is more common today.

Answer

Mesh

Answer

Ring

Answer

Star

Question 7

A technician is choosing a printer for a home office that needs high-quality color photo prints. Which TWO printer types are most suitable?

Accepted Answer

Inkjet. Inkjet printers use liquid ink droplets sprayed through fine nozzles to produce smooth gradients and high-resolution color output, making them ideal for photo printing. Option D (Laser) is also correct because color laser printers use CMYK toner and can produce high-quality color prints suitable for a home office, especially for documents and graphics. Dot matrix (B) is an impact printer using a ribbon, suited only to multipart forms and low-quality text, not photos. A 3D printer (C) creates three-dimensional objects, not 2D photo prints. Thermal printers (E) use heat-sensitive paper and are used for receipts and labels, not high-quality color photos.

Answer

Dot matrix

Answer

3D printer

Answer

Thermal

Question 8

A company is deploying a virtualization server to run multiple application servers. Which THREE resources are typically allocated to a virtual machine?

Accepted Answer

vStorage. vCPU (C) is correct because a hypervisor presents virtual processors to each VM, and the administrator assigns a specific number of virtual CPUs (sockets/cores) drawn from the host's physical CPU resources. vRAM (D) is correct because each VM is configured with a fixed amount of virtual memory that the hypervisor backs with physical RAM (and possibly overcommit or swap files). vStorage (B) is correct because a VM is given virtual disks (VMDK/VHDX/qcow2) that map to datastore or storage-array capacity, which is the standard way storage is allocated per VM. vGPU (A) is not a typical allocation for ordinary application servers, since GPU passthrough or virtual GPU is only assigned for graphics/compute workloads. vNIC (E) is a virtual network adapter that connects a VM to a virtual switch, but it is a connectivity device rather than a compute, memory, or storage resource allocated in the same sense as vCPU, vRAM, and vStorage.

Answer

vGPU

Answer

vNIC

Question 9

Which of the following port types is commonly used to connect a modern external hard drive to a computer and supports data transfer speeds up to 10 Gbps?

Accepted Answer

USB-C (USB 3.1 Gen 2). USB-C (USB 3.1 Gen 2) is a connector and protocol combination that supports up to 10 Gbps data transfer, and it is the standard port on modern external hard drives and laptops. USB 3.1 Gen 2 specifically denotes the 10 Gbps signaling rate, while USB-C describes the reversible connector shape. Together they meet the speed requirement in the question.

Answer

Thunderbolt 3

Answer

USB 2.0

Answer

USB 3.0

Question 10

A technician is setting up a small office network with 10 computers and one printer. The network should allow devices to communicate with each other and share the printer. Which TWO of the following components are essential?

Accepted Answer

Router. A router (A) is essential because it provides the default gateway and routes traffic between the local network and any external networks, while also typically handling DHCP to assign IP addresses to the 10 computers and printer. A switch (B) is essential because it provides the wired Layer 2 connectivity that lets the 10 computers and the printer communicate with each other and share the printer on the LAN. A firewall (C) is not required for basic internal communication and printer sharing, and many small routers include basic firewall features already. An access point (D) is only needed if wireless devices must connect, which is not stated in the scenario. A modem (E) is only needed to connect to an ISP for internet access, which is not required for the stated goal of device-to-device communication and printer sharing.

Answer

Firewall

Answer

Access point

Answer

Modem

Question 11

A user wants to synchronize files, contacts, and calendar between their smartphone and tablet. Which THREE of the following methods can accomplish this?

Accepted Answer

iCloud sync. iCloud sync (A) is correct because Apple's iCloud service synchronizes files via iCloud Drive, contacts, and calendars across iOS/iPadOS devices signed into the same Apple ID. Google account sync (D) is correct because signing into the same Google account on both devices syncs Gmail contacts, Google Calendar, and Drive files across Android or iOS devices. A USB cable connection (E) is correct because connecting a smartphone to a tablet via USB (e.g., MTP/PTP or vendor sync software) allows manual transfer and synchronization of files, contacts, and calendar data. NFC (B) is not designed for bulk data synchronization; it only supports short-range pairing or small data exchanges like Android Beam. Bluetooth pairing (C) can transfer individual files but does not provide full synchronization of contacts and calendars between devices.

Answer

NFC

Answer

Bluetooth pairing

Question 12

A company is setting up a home office for a remote employee. The employee will use a desktop computer, a VoIP phone, and a printer. The office has only one Ethernet wall jack. Which of the following devices would allow all three devices to connect to the network? (Select TWO).

Accepted Answer

Wireless router. Option E (Network switch) is correct because a switch provides multiple Ethernet ports and forwards frames only to the intended MAC address, so the desktop, VoIP phone, and printer can all share the single wall jack via wired connections. Option C (Wireless router) is correct because it also offers multiple switched LAN ports plus Wi-Fi, allowing the wired devices to connect through its LAN ports and any wireless device to join the same network. Option A (Repeater) is incorrect because it merely regenerates a signal to extend distance and does not provide multiple ports for connecting three devices. Option B (Hub) is incorrect because, although it offers multiple ports, it is an obsolete half-duplex device that broadcasts to all ports and causes collisions, making it unsuitable for a modern VoIP and data network. Option D (Modem) is incorrect because it only converts between the ISP's signal (e.g., cable, DSL, or fiber) and Ethernet; it does not provide LAN ports to connect multiple local devices.

Answer

Repeater

Answer

Hub

Answer

Modem

Question 13

A technician is choosing expansion cards for a new workstation. The workstation will be used for high-end gaming and video editing. Which TWO cards are most essential for these tasks?

Answer

Network interface card (NIC)

Answer

TV tuner card

Answer

USB expansion card

Question 14

A network administrator is redesigning a small office network with 20 computers, two servers, and three printers. The network must be reliable and easy to troubleshoot. Which TWO network topologies should the administrator consider?

Accepted Answer

Star. Option A (Star) is correct because a star topology centralizes all 20 computers, two servers, and three printers on a central switch or hub, so a single cable or device failure affects only that node and faults are easy to isolate by checking the central device and individual links. Option E (Mesh) is correct because a full or partial mesh provides redundant paths between critical nodes such as the two servers, so no single link failure disconnects the network, which directly supports the stated reliability requirement. The unmarked options do not belong: a bus topology uses one shared backbone where a single break or termination fault can bring down the entire segment, a ring topology depends on each node passing traffic to the next so one failed node or link can disrupt the loop, and hybrid is a broad combination of topologies rather than a specific topology the administrator would select as one of the two primary answers.

Answer

Hybrid

Answer

Ring

Answer

Bus

Question 15

An IT technician is setting up a home office network. The technician needs to connect multiple devices to the internet and ensure they can communicate with each other. Which THREE devices are essential for this setup?

Accepted Answer

Modem. The modem (A) is essential because it converts the ISP's signal (coax, fiber, or DSL) into an Ethernet/IP connection the home network can use to reach the internet. The router (C) is essential because it performs NAT, DHCP, and routing between the local LAN and the internet, allowing multiple devices to share one public IP and communicate with each other. The switch (E) is essential because it provides the multiple wired Ethernet ports needed to connect several devices on the same LAN so they can communicate locally. A hub (B) is not required and is obsolete, since a switch provides the same connectivity with full-duplex, collision-free operation. A firewall appliance (D) is not essential here because the router already provides basic stateful firewall/NAT protection for a typical home office.

Answer

Hub

Answer

Firewall appliance
