Accepted Answer

The digitizer flex cable is not fully seated in the connector.. The digitizer flex cable must be fully seated and locked into its connector on the tablet's mainboard to establish electrical continuity for touch signals. If the cable is loose or not properly inserted, the touch controller cannot communicate with the digitizer, resulting in a completely unresponsive touch input despite the LCD display functioning correctly.

Answer

The digitizer is not compatible with the tablet model.

Answer

The LCD panel was damaged during the repair.

Answer

The tablet's touch controller needs to be calibrated.

Question 2

A technician is deploying tablets for use in a warehouse where workers wear gloves. The tablets need to be used for scanning barcodes and entering data. Which accessory is most critical for this environment?

Accepted Answer

A rugged case.. In a warehouse environment where workers wear gloves, the most critical accessory is a rugged case because it protects the tablet from drops, dust, and moisture common in industrial settings. While gloves prevent capacitive touchscreen use, a rugged case does not solve input issues but ensures device survival; however, the question asks for the most critical accessory for the environment, and without rugged protection, the tablet would fail quickly. The correct answer is C because it directly addresses the physical hazards of the warehouse, which are more fundamental than input method challenges.

Answer

A screen protector.

Answer

A Bluetooth keyboard.

Answer

A capacitive stylus.

Question 3

A field technician frequently uses a ruggedized tablet outdoors for data collection. They complain that the screen is hard to read in direct sunlight. Which accessory would best improve screen visibility without adding significant bulk?

Accepted Answer

An anti-glare screen protector. An anti-glare screen protector uses a matte finish with microscopic ridges that diffuse reflected light, reducing glare and improving contrast in bright environments. This directly addresses the technician's issue of poor readability in direct sunlight without adding significant bulk to the ruggedized tablet.

Answer

A privacy filter

Answer

A portable external monitor

Answer

An external battery pack

Question 4

A user wants to connect their smartphone to a hotel TV to stream a presentation during a conference. The TV has only an HDMI port and no wireless capabilities. Which accessory is most appropriate for this task?

Accepted Answer

An MHL-to-HDMI adapter. MHL (Mobile High-Definition Link) allows a smartphone to output video and audio through its USB port (often USB-C or micro-USB) and converts it to HDMI, which is exactly what is needed to connect to a TV with only an HDMI port. This adapter is the most appropriate because it directly bridges the smartphone's mobile output to the TV's HDMI input without requiring any wireless network or additional power source.

Answer

A USB-C to USB-A hub

Answer

A Bluetooth speaker

Answer

A wireless display adapter like Chromecast

Question 5

A technician is setting up a new file server that needs to be accessible to employees both from the local network and remotely over the internet. The server will host shared folders. Which protocol should the technician ensure is properly configured and secured on the server for file access?

Accepted Answer

SMB. SMB (Server Message Block) is the native protocol used by Windows for file and printer sharing, and it is the correct choice for a file server that needs to be accessible both locally and remotely. SMB supports authentication, encryption (via SMB 3.x), and can be securely tunneled over VPN or through port 445 with proper firewall rules, making it ideal for shared folder access in a mixed network environment.

Answer

FTP

Answer

NFS

Answer

HTTP

Question 6

A technician is configuring a new web server that must support both standard and encrypted web traffic. Which two ports should be opened in the firewall?

Accepted Answer

Port 80 and 443. Standard web traffic uses HTTP on port 80, while encrypted web traffic uses HTTPS on port 443. Opening these two ports in the firewall allows the web server to serve both unencrypted and TLS/SSL-encrypted content to clients.

Answer

Port 22 and 21

Answer

Port 3389 and 5900

Answer

Port 53 and 123

Question 7

A customer reports that their laptop frequently disconnects from the Wi-Fi in their home office, but works fine in other rooms. The office is located in a detached garage, and the wireless router is in the main house. Which wireless networking technology would best solve this issue without running cables?

Accepted Answer

Wireless mesh network. A wireless mesh network is the best solution because it extends Wi-Fi coverage to the detached garage without running cables. Mesh nodes communicate wirelessly with each other, creating a seamless network that overcomes the range and obstruction issues caused by the distance and building materials between the main house and garage.

Answer

5 GHz frequency band

Answer

Powerline networking adapters

Answer

802.11ac standard

Question 8

A user complains that they cannot access any websites, but they can ping external IP addresses like 8.8.8.8 successfully. Other devices on the same network work fine. Which network service is most likely failing on this user's computer?

Accepted Answer

DNS. The user can ping external IP addresses (e.g., 8.8.8.8) successfully, which confirms that IP connectivity, routing, and NAT are working. However, they cannot access websites by name, which requires DNS resolution to translate domain names into IP addresses. Since other devices on the same network work fine, the issue is isolated to this computer's DNS client configuration or service, making DNS the most likely failing service.

Answer

DHCP

Answer

NAT

Answer

Proxy

Question 9

A technician is configuring a new wireless router for a home office. The customer wants to ensure that guests can access the internet but cannot see other devices on the main network. Which feature should the technician enable on the router?

Accepted Answer

Guest network. Enabling a guest network creates a separate SSID and VLAN (or subnet) that isolates guest traffic from the main LAN. This prevents guests from accessing local devices (e.g., printers, file shares) while still providing internet access through the router's NAT. The isolation is typically achieved via client isolation or AP isolation settings, ensuring Layer 2 separation between the guest and main networks.

Answer

MAC address filtering

Answer

Port forwarding

Answer

WPS (Wi-Fi Protected Setup)

Question 10

A network administrator needs to segment traffic between the accounting and HR departments to prevent unauthorized access, while still allowing both to reach the internet. The company uses a single managed switch and a router. Which configuration approach meets these requirements?

Accepted Answer

Configure VLANs on the switch and set up a trunk port to the router with subinterfaces. VLANs logically segment traffic between departments on a single switch, and configuring a trunk port to the router with subinterfaces (using VLAN tagging) allows inter-VLAN routing for internet access while maintaining isolation between the accounting and HR VLANs. This approach meets the requirement of preventing unauthorized access between departments while enabling shared internet connectivity through the router.

Answer

Create two separate subnets and connect each department to a different physical switch

Answer

Assign static IPs to all devices and enable MAC address filtering on the switch

Answer

Use a firewall between the two departments and disable inter-VLAN routing

Question 11

A network administrator is configuring a new firewall to allow remote employees to securely access internal resources. The requirement is to encrypt all traffic between the remote client and the internal network. Which protocol should be used?

Accepted Answer

IPsec. IPsec is the correct choice because it provides end-to-end encryption at the network layer (Layer 3), securing all IP traffic between a remote client and an internal network. It operates in tunnel mode to encapsulate the entire original IP packet, ensuring confidentiality, integrity, and authentication for remote access VPNs. SSL/TLS operates at the transport layer and is typically used for securing individual application sessions (e.g., HTTPS), not for encrypting all traffic from a remote client to an entire internal network.

Answer

SSL/TLS

Answer

L2TP

Answer

HTTP

Question 12

A company's network uses a router with a built-in 4-port switch. The IT manager wants to segment the network into two separate broadcast domains for security. What additional hardware is required?

Accepted Answer

A managed switch. A managed switch is required because it can be configured with VLANs (IEEE 802.1Q) to create multiple broadcast domains on a single physical switch. The built-in 4-port switch on the router cannot be segmented into separate broadcast domains without VLAN support, which only a managed switch provides.

Answer

A second router

Answer

A hub

Answer

A wireless access point

Question 13

A technician is configuring a small branch office network with 30 devices. The network uses a single router with DHCP enabled. To conserve IP addresses, the technician decides to use a subnet that provides exactly enough usable addresses for the devices, with minimal waste. Which subnet mask should the technician choose?

Accepted Answer

255.255.255.224. The network requires exactly 30 usable IP addresses. A /27 subnet (mask 255.255.255.224) provides 32 total addresses, with 30 usable (2^5 - 2 = 30), matching the requirement with minimal waste. This is the most efficient choice because it supplies the exact number of hosts needed without leaving a large pool of unused addresses.

Answer

255.255.255.0

Answer

255.255.255.240

Answer

255.255.255.192

Question 14

A small business is moving to a new office that already has a fiber-optic termination point installed. They need the fastest symmetrical speeds for cloud-based applications. Which internet connection type should they choose?

Accepted Answer

Fiber-optic. Fiber-optic internet provides symmetrical speeds (equal upload and download) essential for cloud-based applications that require fast data transfer in both directions. Unlike other connection types, fiber uses light signals through glass strands, offering low latency and high bandwidth that scale to meet business needs without the distance limitations of copper-based technologies.

Answer

DSL

Answer

Cable broadband

Answer

Satellite

Question 15

A technician is configuring a new SOHO router for a client who has a DSL internet connection. What type of cable will the technician use to connect the router to the wall jack?

Accepted Answer

Telephone cable (RJ-11). DSL (Digital Subscriber Line) transmits data over standard copper telephone lines using frequencies above the voice band. The wall jack for DSL is a standard RJ-11 phone jack, so the technician must use a telephone cable with RJ-11 connectors to connect the router's DSL port to the wall jack.

Answer

Coaxial cable (RG-6)

Answer

Fiber optic cable

Answer

Ethernet cable (RJ-45)

Question 16

A company is deploying VoIP phones and needs a connection with low latency and consistent speeds. They are choosing between cable broadband and fiber-optic. Which factor makes fiber the better choice?

Accepted Answer

Fiber provides symmetrical upload and download speeds. Fiber-optic connections use separate strands for upstream and downstream data, enabling symmetrical speeds. For VoIP, this ensures consistent upload bandwidth for voice packets, which is critical for low latency and jitter. Cable broadband (DOCSIS) typically has asymmetric speeds due to shared upstream channels, making fiber the better choice for real-time voice traffic.

Answer

Fiber has higher download speeds

Answer

Fiber is less prone to electromagnetic interference

Answer

Fiber is cheaper than cable

Question 17

A user's laptop connects to the office Wi-Fi but cannot access the internet. Other devices on the same network work fine. The laptop's IP address is 169.254.25.14. What is the most likely cause?

Accepted Answer

The DHCP server is not responding or the laptop cannot reach it.. The IP address 169.254.25.14 falls within the Automatic Private IP Addressing (APIPA) range (169.254.0.0/16), which Windows assigns when a DHCP client fails to receive an IP lease from a DHCP server. Since other devices on the same network work fine, the issue is isolated to this laptop's inability to communicate with the DHCP server, not a network-wide outage. This makes option C correct.

Answer

The DNS server is unreachable.

Answer

The laptop's wireless adapter driver is corrupted.

Answer

The SSID is hidden and requires manual entry.

Question 18

A user reports that their external monitor connected to a laptop via HDMI flickers intermittently. The laptop's built-in display works fine. You have tried a different HDMI cable and a different monitor, but the flickering persists. What should you check next?

Accepted Answer

Inspect the HDMI port on the laptop for physical damage or debris.. The issue is isolated to the external monitor connection, and swapping cable and monitor didn't help. This points to a defective or loose HDMI port on the laptop, which can cause intermittent signal loss. Testing with a known-good display on a different port or device confirms the port as the root cause.

Answer

Update the graphics driver to the latest version.

Answer

Replace the video cable with a DisplayPort cable.

Answer

Disable the laptop's built-in display to force the external monitor as primary.

Question 19

A user wants to mirror their Android smartphone's screen to a smart TV that does not support Miracast. The TV has HDMI and USB ports. Which device should the technician recommend?

Accepted Answer

A Chromecast device. A Chromecast device connects to the TV via HDMI and uses Wi-Fi Direct (not Miracast) to receive a screen mirror from an Android smartphone. Since the TV lacks Miracast support but has an HDMI port, Chromecast provides the necessary hardware and protocol (Google Cast) to enable wireless display mirroring.

Answer

A USB-C to HDMI cable

Answer

A Bluetooth transmitter

Answer

An NFC tag

Question 20

A user is setting up a new tablet and wants to share its internet connection with a laptop that has no cellular capability. The tablet has a cellular data plan. Which configuration should the user enable on the tablet?

Accepted Answer

Enable Wi-Fi hotspot.. Enabling a Wi-Fi hotspot on the tablet creates a local wireless network that the laptop can connect to, sharing the tablet's cellular data connection. This is the standard method for tethering when the client device (laptop) lacks cellular capability but has Wi-Fi. Bluetooth pairing (option A) can also share internet, but it is slower and not the primary method for a laptop that expects a Wi-Fi connection.

Answer

Enable Bluetooth pairing only.

Answer

Enable airplane mode.

Answer

Enable NFC.
