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

Accepted Answer

A stand and a charging dock.. A stand securely mounts the tablet on the counter at an ergonomic viewing angle, while a charging dock provides continuous power to keep the tablet operational throughout the day without battery depletion. These two accessories directly address the deployment requirements of fixed mounting and uninterrupted power for a stationary point-of-sale system.

Answer

A rugged case and a Bluetooth keyboard.

Answer

A screen protector and a stylus.

Answer

A portable battery pack and a car charger.

Question 2

A technician is configuring a tablet for a delivery driver who needs to navigate and take photos of packages. The driver complains the tablet's screen is hard to see in direct sunlight. Which accessory would best address this issue?

Accepted Answer

An anti-glare screen protector with a matte finish.. An anti-glare screen protector with a matte finish reduces reflections by scattering ambient light through a microscopic textured surface, which improves readability in direct sunlight without increasing the display's inherent brightness. This directly addresses the driver's issue of screen glare outdoors, whereas other options either fail to reduce glare or introduce impracticality for mobile use.

Answer

A high-brightness screen protector that boosts luminance.

Answer

A privacy screen filter to reduce viewing angles.

Answer

A sunshade hood that attaches to the tablet case.

Question 3

A user reports that their laptop can connect to the internet when using a wired connection at home, but cannot connect to any network resources when using Wi-Fi at the office. The office uses DHCP with a scope of 192.168.10.0/24. The laptop's IP configuration shows an address of 169.254.15.22. What is the most likely cause of this issue?

Accepted Answer

The laptop cannot reach the DHCP server on the office network.. The IP address 169.254.15.22 is an Automatic Private IP Addressing (APIPA) address (169.254.0.0/16), which Windows assigns when a DHCP client fails to receive a lease from a DHCP server. Since the laptop can connect via wired Ethernet at home but not via Wi-Fi at the office, the most likely cause is that the Wi-Fi adapter cannot communicate with the office DHCP server, preventing it from obtaining a valid 192.168.10.0/24 address.

Answer

The laptop's Wi-Fi adapter is disabled in Device Manager.

Answer

The office DHCP server is out of available IP addresses.

Answer

The laptop's DNS settings are misconfigured.

Question 4

During a network upgrade, you need to identify which cable in a messy patch panel corresponds to a specific office wall jack. The cables are not labeled. Which tool should you use?

Accepted Answer

Toner probe. A toner probe (inductive amplifier and tone generator) is the correct tool for tracing an unlabeled cable from a patch panel to a specific wall jack. The tone generator injects a distinctive audio signal onto the wire pair, and the inductive probe detects that signal without requiring a direct electrical connection, allowing you to identify the correct cable even in a dense, messy bundle.

Answer

Cable tester

Answer

Multimeter

Answer

Loopback plug

Question 5

A customer complains that their external USB 3.0 hard drive is only transferring files at USB 2.0 speeds (about 30-40 MB/s). They have confirmed the drive supports USB 3.0. What is the most likely cause?

Accepted Answer

The USB cable is only rated for USB 2.0.. USB 3.0 requires a SuperSpeed-capable cable with the additional data pairs; a USB 2.0-only cable physically fits the connector but lacks those pairs, so the link negotiates down to High Speed (480 Mbps, ~30-40 MB/s). The drive and port may both be 3.0-capable, but the cable is the bottleneck. Swapping to a certified USB 3.0 (or better) cable restores SuperSpeed throughput.

Answer

The external drive is failing and needs to be replaced.

Answer

The drive is formatted with FAT32, which limits transfer speeds.

Answer

The computer's USB drivers are outdated.

Question 6

A company is setting up a guest wireless network in a conference room. They want to ensure that guests can access the internet but cannot communicate with internal corporate devices. The network uses a single router and a switch. Which configuration on the router will best achieve this?

Accepted Answer

Create a separate VLAN for the guest network and apply an ACL to block traffic to the internal network.. Creating a separate VLAN for the guest network isolates guest traffic at Layer 2, and applying an ACL on the router's VLAN interface blocks traffic destined for the internal network while permitting internet-bound traffic. This ensures guests cannot reach internal corporate devices, meeting the security requirement without additional hardware.

Answer

Configure the router to use DHCP for the guest network.

Answer

Disable the SSID broadcast for the guest network.

Answer

Use a wireless access point with a built-in firewall.

Question 7

A company is moving to a new building that has no existing internet infrastructure. They need the highest possible download speeds with low latency for cloud applications. Which connection type should they choose?

Accepted Answer

Fiber optic. Fiber optic uses light pulses transmitted through glass or plastic strands, offering symmetrical gigabit speeds (e.g., 1 Gbps or higher) with extremely low latency (often <5 ms). This makes it ideal for cloud applications requiring high download speeds and real-time responsiveness, unlike older copper-based or wireless technologies.

Answer

DSL

Answer

Cable

Answer

Fixed wireless

Question 8

A customer reports that their network printer is not accessible from any computer on the network. The printer is connected to a switch via Ethernet, and the switch port LED is blinking green. The technician pings the printer's IP address from a computer and gets no reply. What is the most likely cause?

Accepted Answer

The printer has an IP address conflict with another device.. The blinking green LED on the switch port indicates a good physical connection and active link, ruling out a faulty cable or administratively down port. Since the printer is not responding to pings from any computer, the most likely cause is an IP address conflict, where another device on the network is using the same IP address, causing the printer to be unreachable. This conflict can occur due to static IP misconfiguration or a DHCP server assigning the same address to multiple devices.

Answer

The printer's Ethernet cable is faulty.

Answer

The switch port is administratively down.

Answer

The printer's print spooler service is stopped.

Question 9

A technician is setting up a cloud-based application that must handle unpredictable spikes in user traffic. The application should automatically add more virtual servers during peak times and remove them when traffic decreases. Which cloud concept is this?

Accepted Answer

Elasticity. Elasticity is the cloud concept that automatically scales resources up or down based on real-time demand, such as unpredictable traffic spikes. It matches the requirement to add virtual servers during peak times and remove them when traffic decreases. Scalability refers to the ability to handle growth, but not necessarily automatic, dynamic adjustment.

Answer

Scalability

Answer

High availability

Answer

Load balancing

Question 10

A network administrator wants to ensure that all devices on a subnet automatically receive IP addresses from a specific range, and that the lease time is set to 8 hours. Which configuration file or service should be modified?

Accepted Answer

DHCP scope. The DHCP scope defines the range of IP addresses that a DHCP server can assign to clients on a subnet, along with lease duration and other options. By modifying the DHCP scope, the administrator can set the specific IP address range and configure the lease time to 8 hours, ensuring all devices on that subnet automatically receive addresses from that pool.

Answer

DNS zone file

Answer

NAT rules

Answer

QoS policy

Question 11

A user reports that their email client can receive messages but cannot send any. The email server settings are correct, and the user can connect to the internet. The firewall is blocking outbound traffic on certain ports. Which protocol and port combination is likely blocked?

Accepted Answer

SMTP on port 25. SMTP (Simple Mail Transfer Protocol) is used for sending outgoing email messages. By default, SMTP uses port 25. If the firewall blocks outbound traffic on port 25, the email client can still receive messages (using POP3 or IMAP) but will be unable to send any, perfectly matching the user's symptoms.

Answer

POP3 on port 110

Answer

IMAP on port 143

Answer

HTTPS on port 443

Question 12

A small business wants to run three different operating systems on a single physical server to save space and power. Each OS must have its own dedicated CPU cores, RAM, and storage, and the hypervisor must run directly on the hardware without a host OS. Which type of hypervisor should be deployed?

Accepted Answer

Type 1 hypervisor. This scenario describes a Type 1 (bare-metal) hypervisor, which installs directly on hardware and allocates dedicated resources to each virtual machine. Type 1 hypervisors are used in data centers and server virtualization to maximize performance and isolation.

Answer

Type 2 hypervisor

Answer

Container-based virtualization

Answer

Emulation virtualization

Question 13

A user reports that their computer cannot connect to the internet after being moved to a new office. The computer receives an IP address starting with 169.254.x.x. Which network service is failing to provide a valid IP configuration?

Accepted Answer

DHCP. The 169.254.x.x address is an Automatic Private IP Addressing (APIPA) address, assigned by Windows when a DHCP server is unreachable. Since the computer cannot obtain a valid IP configuration from a DHCP server, the DHCP service is failing. DNS, NAT, and ARP do not assign IP addresses dynamically.

Answer

DNS

Answer

NAT

Answer

ARP

Question 14

A company's web server is accessible from the internal network but not from the internet. The server has a static IP of 192.168.1.10. The firewall is configured to allow HTTP and HTTPS traffic. What is the most likely missing configuration?

Accepted Answer

Port forwarding rules are not configured on the firewall. The server has a private IP (192.168.1.10), so for internet clients to reach it, the firewall must translate the public destination IP to the private server IP using port forwarding (a form of Destination NAT). Without port forwarding rules, the firewall will receive HTTP/HTTPS traffic on its public interface but not know which internal server to send it to, even though the firewall's ACL allows the traffic. Option C correctly identifies this missing configuration.

Answer

The server's default gateway is set to the firewall's LAN IP

Answer

The firewall's NAT is disabled

Answer

The server has a public IP address assigned

Question 15

A small business is moving to a new office and wants to connect all their computers, printers, and a server. They have a limited budget and need a simple, wired network that does not require internet access initially. Which network type should they implement?

Accepted Answer

Local Area Network (LAN). A Local Area Network (LAN) is the correct choice because it connects devices within a single physical location, such as an office, using wired Ethernet (IEEE 802.3) and switches. It requires no internet access and is cost-effective for a small business with a limited budget, as it only needs basic hardware like a switch and Cat5e/Cat6 cabling.

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)

Answer

Metropolitan Area Network (MAN)
