Question 2

A technician is servicing a smartphone with a non-functional earpiece speaker during calls, but the loudspeaker works fine. After testing, the earpiece speaker itself is determined to be good. Which component is most likely faulty?

Accepted Answer

The mainboard audio IC (codec).. Since the earpiece speaker itself is confirmed good, the fault lies in the signal path between the mainboard and the speaker. The audio IC (codec) on the mainboard is responsible for processing and routing the audio signal specifically to the earpiece during calls. A failure in this component would prevent the earpiece from working while the loudspeaker, which uses a separate audio path, remains functional.

Answer

The charging port flex cable.

Answer

The SIM card slot.

Answer

The battery connector.

Question 3

A small office has a single router with four LAN ports. The network uses the 192.168.1.0/24 subnet, and the router's LAN IP is 192.168.1.1. A technician needs to add a new printer that must have a static IP address outside the DHCP range (192.168.1.100-192.168.1.200) but still be reachable by all devices. Which IP address should the technician assign to the printer?

Accepted Answer

192.168.1.50. (192.168.1.50) is correct because it falls within the 192.168.1.0/24 subnet, is outside the DHCP range of 192.168.1.100–200, and is on the same broadcast domain as all devices, ensuring reachability without an IP conflict.

Answer

192.168.1.150

Answer

10.0.0.50

Answer

192.168.2.50

Question 4

A company is upgrading its network to support 10 Gbps speeds for a server farm. The existing cabling is Cat6a, and the switches are Gigabit. The IT manager wants to minimize cost while achieving 10 Gbps. Which hardware change is required?

Accepted Answer

Install 10 Gbps switches and use the existing Cat6a cabling.. Cat6a cabling is rated to support 10 Gbps Ethernet up to 100 meters, so no cable replacement is needed. The bottleneck is the existing Gigabit switches, which must be upgraded to 10 Gbps switches to achieve the desired speed. This is the most cost-effective approach because it avoids the expense of new cabling.

Answer

Replace the Cat6a cabling with Cat7 cabling.

Answer

Replace the switches with Gigabit models that have SFP+ ports for fiber.

Answer

Add a repeater to boost the signal on the existing Cat6a cabling.

Question 5

During a network upgrade, a technician replaces an old 10/100 Mbps switch with a new gigabit switch. After the change, several users report that their internet connection is slow. The technician checks the switch and sees that some ports show 100 Mbps instead of 1000 Mbps. What is the most likely cause?

Accepted Answer

The connected devices have 10/100 Mbps NICs. The most likely cause of the switch ports operating at 100 Mbps instead of 1000 Mbps is that the connected devices have 10/100 Mbps NICs. Gigabit Ethernet requires both the switch port and the connected device to support 1000BASE-T; if the NIC only supports 10/100, the switch will auto-negotiate down to the highest common speed, which is 100 Mbps. This explains why only some users experience slowness—those with older NICs are limited to 100 Mbps while others with gigabit-capable NICs get full speed.

Answer

The switch ports are configured for half-duplex

Answer

The Ethernet cables are Cat5 instead of Cat5e or Cat6

Answer

The switch has a faulty power supply causing reduced performance

Question 6

A company uses a cloud-based VoIP service, and users report intermittent call drops and poor audio quality. Network monitoring shows high jitter and packet loss. Which service is most likely contributing to the problem?

Accepted Answer

The network is not prioritizing VoIP traffic via QoS.. High jitter and packet loss directly degrade real-time VoIP traffic, causing call drops and poor audio. QoS (Quality of Service) mechanisms like DiffServ or 802.1p prioritize voice packets over other traffic, ensuring low latency and consistent delivery. Without QoS, the network treats VoIP packets the same as bulk data, leading to the reported symptoms.

Answer

The DHCP server is leasing IP addresses with a short lease time.

Answer

The DNS server is responding slowly to queries.

Answer

The SIP server is overloaded with registration requests.

Question 7

A customer wants to switch from cable internet to a fixed wireless ISP (WISP) to reduce costs. What is a critical requirement for the WISP installation?

Accepted Answer

A clear line-of-sight to the provider's tower.. Fixed wireless internet (WISP) relies on radio frequency (RF) signals transmitted between an antenna at the customer's location and a tower operated by the provider. Unlike cable or fiber, RF signals are highly susceptible to physical obstructions such as buildings, trees, or terrain; therefore, a clear line-of-sight (LOS) is a critical requirement for establishing a reliable connection. Without LOS, signal attenuation or multipath interference will likely prevent the link from achieving usable throughput or even establishing a connection at all.

Answer

A direct fiber connection from the provider's office.

Answer

A dedicated phone line for the modem.

Answer

A satellite dish with a 2-foot diameter.

Question 8

A city government wants to provide free public Wi-Fi in a downtown area spanning 2 square miles. The network must handle hundreds of simultaneous users and be accessible from streets and parks. Which network type is most appropriate for this deployment?

Accepted Answer

Metropolitan Area Network (MAN). A Metropolitan Area Network (MAN) is designed to cover a geographic area larger than a LAN but smaller than a WAN, typically spanning a city or a large campus. For a 2-square-mile downtown area with hundreds of simultaneous users, a MAN provides the necessary range, high capacity, and centralized management to deliver public Wi-Fi access across streets and parks. Technologies such as WiMAX (IEEE 802.16) or carrier-grade Wi-Fi mesh networks are commonly used in MAN deployments to ensure seamless coverage and user density.

Answer

Local Area Network (LAN)

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)

Question 9

A user complains that their external monitor shows a 'No Signal' message when connected to their laptop via HDMI. The laptop display works fine. You test the monitor with another computer and it works. What should you check first?

Accepted Answer

Press the function key to switch display modes. The most common cause of an external monitor showing 'No Signal' when the laptop display works fine is that the laptop is not sending video output to the external port. Pressing the function key (e.g., Fn+F4, Fn+F8, or a dedicated display toggle key) cycles through display modes (e.g., PC screen only, Duplicate, Extend, Second screen only). This is the first and simplest troubleshooting step because it directly addresses the output routing without introducing hardware or driver changes.

Answer

Replace the HDMI cable

Answer

Update the laptop's BIOS

Answer

Reinstall the graphics driver

Question 10

A client wants to set up a network in a single large warehouse where employees use handheld scanners to track inventory. The scanners need to communicate with a central server located in the same building, but no internet access is required. Which network type should be configured?

Accepted Answer

Local Area Network (LAN). A Local Area Network (LAN) is the correct choice because it connects devices within a limited geographic area, such as a single warehouse, using high-speed Ethernet or Wi-Fi. The handheld scanners and central server need to communicate locally, and a LAN is well-suited for this purpose, operating effectively even without requiring internet access, which aligns with the client's needs. Technologies like IEEE 802.3 (Ethernet) or IEEE 802.11 (Wi-Fi) provide the necessary low-latency, high-bandwidth connectivity for real-time inventory tracking.

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)

Answer

Metropolitan Area Network (MAN)

Question 11

A technician is troubleshooting a laser printer that produces pages with a faint ghost image of the previous page. The ghost image is slightly offset. Which component is most likely the cause?

Accepted Answer

The drum's cleaning blade is worn.. Ghosting in laser printers is often caused by a worn or damaged cleaning blade on the drum, or a failing fuser that doesn't fully fuse toner. The offset ghost indicates residual toner from the previous page not being cleaned off the drum.

Answer

The toner cartridge is low on toner.

Answer

The fuser assembly is overheating.

Answer

The pickup rollers are dirty.

Question 12

A technician is building a new gaming PC and installs two 16 GB DDR5-5600 modules in the correct slots. The system boots and shows 32 GB in the BIOS, but the memory speed is reported as 4800 MHz instead of 5600 MHz. What is the most likely reason for this?

Accepted Answer

XMP or EXPO has not been enabled in the BIOS.. DDR5 modules default to a standard JEDEC speed (often 4800 MHz) for stability. To achieve the rated 5600 MHz, the user must enable XMP (Intel) or EXPO (AMD) in the BIOS, which applies the manufacturer's overclocking profile. This tests knowledge of memory speed configuration beyond plug-and-play.

Answer

The RAM modules are defective and cannot run at their rated speed.

Answer

The motherboard does not support DDR5-5600.

Answer

The RAM is installed in the wrong slots.

Question 13

A user wants to upgrade their laptop from a traditional HDD to an SSD for faster boot times. They have a SATA III interface available. Which type of SSD should you recommend for the best performance without requiring an adapter?

Accepted Answer

2.5-inch SATA SSD. A 2.5-inch SATA SSD is the direct replacement for a laptop HDD, using the same interface and form factor. NVMe M.2 drives require an M.2 slot, which this laptop may not have. mSATA is less common and not standard in most laptops.

Answer

Question 14

A technician is tasked with upgrading the RAM in a desktop motherboard that has four DIMM slots. The existing configuration has two 4GB sticks in slots A1 and B1. The user wants to add two more 4GB sticks for a total of 16GB. After installing the new sticks in slots A2 and B2, the system boots but only shows 8GB of RAM. What is the most likely cause?

Accepted Answer

The new RAM is incompatible with the existing RAM. When mixing RAM modules, even if they are the same size, they may not be compatible if they have different timings, speeds, or ranks. The motherboard may default to the lowest common denominator or fail to recognize mismatched modules. This is a common issue when not using matched kits.

Answer

The new RAM is not seated properly

Answer

The motherboard does not support four sticks of RAM

Answer

The BIOS needs an update to support higher capacity

Question 15

A technician is installing a new M.2 NVMe SSD in a desktop computer. After installation, the drive is not listed in the operating system's disk management tool, but it appears in the UEFI firmware interface. What should the technician do first?

Accepted Answer

Initialize the disk in Disk Management and create a volume.. When a drive is recognized in UEFI but not in the OS, it often means the drive is not initialized or formatted. Disk Management can initialize the drive and assign a file system, making it usable by the OS.

Answer

Update the UEFI firmware to the latest version.

Answer

Change the SATA mode from AHCI to IDE in UEFI.

Answer

Reseat the M.2 drive in the slot.
