220-1201 Practice Exam 51 — 20 Questions

Question 1

During a printer installation, the setup wizard asks for the printer's IP address. The multifunction device is connected via Ethernet and has a static IP. Where can you find the IP address on the printer itself?

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

Accepted Answer

By pressing the 'Home' button, then navigating to 'Network Settings' or 'Information'.. Multifunction printers with a static IP expose their network configuration through the built-in control panel menu. Pressing the 'Home' button and navigating to 'Network Settings' or an 'Information'/'Reports' section displays the assigned IP address, subnet mask, and gateway directly on the device's LCD. This is the standard method for retrieving network details without needing external tools or documentation.

Answer

On the back of the printer near the Ethernet port.

Answer

By looking at the toner cartridge label.

Answer

By checking the DHCP server logs on the network.

Question 2

A company deploys a load balancer to distribute traffic across three web servers. Users report that they occasionally see outdated content or are asked to log in repeatedly. Which network service configuration is most likely missing to maintain session persistence?

Accepted Answer

Session persistence (sticky sessions). Session persistence (sticky sessions) ensures that all requests from a given user session are directed to the same backend web server. Without it, the load balancer may distribute requests across different servers, causing the user to see outdated content if one server has stale cached data, or to be asked to log in repeatedly if the session state is stored locally on each server rather than in a shared database.

Answer

DNS round-robin

Answer

DHCP reservation

Answer

Port forwarding

Question 3

A thermal printer used for shipping labels is producing faint, hard-to-read labels. The printer has plenty of thermal paper loaded. What is the most likely cause?

Accepted Answer

The printhead is dirty or worn. Faint, hard-to-read labels from a thermal printer with plenty of paper are most commonly caused by a dirty or worn printhead. The printhead applies heat to the thermal paper to create the image; if it is dirty, heat transfer is uneven, and if worn, it may not reach the required temperature. Cleaning or replacing the printhead typically resolves the issue.

Answer

The paper is upside down

Answer

The printer driver is incorrect

Answer

The paper is expired

Question 4

A technician is configuring a new email server for a small business. Employees need to send and receive email from their desktop clients (Outlook) and also access email via a web browser. Which combination of protocols should the technician configure on the server to support both client types?

Accepted Answer

SMTP, POP3, and HTTP. SMTP is the standard protocol for sending outgoing email, POP3 allows desktop clients like Outlook to download and store emails locally, and HTTP enables web browser access to the email server (often via a webmail interface). This combination supports both client types: Outlook uses SMTP/POP3, while a browser uses HTTP to access the webmail service.

Answer

FTP, SMTP, and DNS

Answer

IMAP, SNMP, and HTTPS

Answer

DHCP, SMTP, and POP3

Question 5

A customer wants to connect a laptop to a 4K TV for a presentation. The laptop has an HDMI 1.4 port, and the TV supports HDMI 2.0. What is the maximum resolution and refresh rate the customer can expect?

Accepted Answer

4K at 30Hz. HDMI 1.4 is limited to a maximum data rate of 10.2 Gbps, which supports 4K (3840×2160) only at 30Hz due to insufficient bandwidth for 60Hz. The TV's HDMI 2.0 capability does not increase the laptop's output; the connection operates at the lower version's capabilities. Thus, the maximum achievable is 4K at 30Hz.

Answer

4K at 60Hz

Answer

1080p at 120Hz

Answer

1440p at 60Hz

Question 6

After deploying a new 802.11ac access point, users report that some devices can connect but others cannot, even though they are in the same room. All devices support 5 GHz. What is the most likely cause?

Accepted Answer

The devices have incorrect SSID credentials.. The scenario describes a new 802.11ac access point where some devices connect and others cannot, and all devices support 5 GHz. Since 802.11ac operates on 5 GHz, disabling 2.4 GHz radios would not prevent these devices from connecting. Using a non-overlapping channel is a best practice and would not cause selective failures. An overloaded AP can prevent new clients from associating, but the question gives no indication of a high-density environment or client limit. If only some devices have incorrect SSID credentials, those devices will fail authentication while devices with correct credentials connect successfully, directly explaining the selective connectivity.

Answer

The access point is using a non-overlapping channel.

Answer

The access point has 2.4 GHz radios disabled.

Answer

The access point is overloaded with clients.

Question 7

A technician is configuring a virtual machine to host a database server that requires consistent high disk I/O performance. The host uses a RAID 10 array of SSDs. Which virtual disk type should the technician select to minimize overhead and maximize performance?

Accepted Answer

Fixed-size virtual disk. A fixed-size virtual disk preallocates all storage space at creation, eliminating the overhead of dynamically growing the file and reducing fragmentation. This provides more consistent high I/O performance, which is critical for a database server. Dynamically expanding and thin-provisioned disks incur allocation overhead during writes.

Answer

Dynamically expanding virtual disk

Answer

Differencing virtual disk

Answer

Thin provisioned virtual disk

Question 8

A multifunction printer is connected to a network via Ethernet and also has a USB port for direct printing. A user plugs a USB flash drive into the printer to print a PDF, but the printer does not recognize the drive. The drive works on other computers. What is the most likely cause?

Accepted Answer

The USB flash drive is formatted as NTFS, which the printer does not support.. The most likely cause is that the USB flash drive is formatted with NTFS, which many printers do not support for direct printing. Printers typically support FAT32 or exFAT file systems. Since the drive works on other computers, the issue is likely the file system compatibility with the printer's USB port.

Answer

The PDF file is password-protected.

Answer

The printer's USB port is only for service use.

Answer

The printer's IP address is conflicting with another device.

Question 9

A user reports that their computer does not power on at all. The technician verifies the power cord is connected and the wall outlet works. When the PSU is turned on, no fans spin and no LEDs light up. What should the technician check first?

Accepted Answer

Check if the power supply's on/off switch is set to the '1' (on) position.. The power supply switch is a simple but common oversight; if it is in the off (0) position, no power reaches the system. Always verify this before more complex troubleshooting. Other steps like testing the PSU with a multimeter or paperclip test come after confirming the switch is on.

Answer

Replace the CMOS battery.

Answer

Reseat the RAM modules.

Answer

Test the PSU with a multimeter.

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 user reports that their laptop screen flickers intermittently, but the flickering stops when they adjust the screen angle. What is the most likely hardware issue?

Accepted Answer

A loose or damaged display cable. Intermittent flickering that changes with screen angle is the classic symptom of a loose or damaged display cable (typically the LVDS or eDP ribbon cable connecting the motherboard to the LCD panel). Adjusting the hinge flexes the cable, temporarily restoring or breaking the connection, which is why the symptom correlates with angle. This is a mechanical/connection fault, not a component failure.

Answer

A failing backlight LED

Answer

A defective graphics chip

Answer

Incorrect display refresh rate setting

Question 12

A user reports that their laser printer is producing pages with vertical black streaks. The streaks appear in the same location on every page, even after cleaning the glass and performing a calibration. Which component is most likely causing this issue?

Accepted Answer

Toner cartridge drum. Vertical black streaks that repeat in the same location on every page and persist after cleaning and calibration point to a scratched or contaminated toner cartridge drum. The drum is a cylindrical photosensitive surface that transfers toner to paper; a scratch or debris line on the drum deposits toner along a vertical path on every rotation, producing identical streaks page after page.

Answer

Fuser assembly

Answer

Pickup rollers

Answer

Transfer roller

Question 13

A technician is tasked with enabling virtualization on a desktop to run a hypervisor. After enabling the feature in the OS, the hypervisor still reports that virtualization is disabled. What should be checked in the firmware?

Accepted Answer

Enable Intel VT-x or AMD-V in the BIOS/UEFI. Even after enabling virtualization in the OS, the hypervisor reports it is disabled because hardware-assisted virtualization (Intel VT-x or AMD-V) must be enabled in the BIOS/UEFI firmware. The OS setting only allows the hypervisor to use the feature; the CPU feature itself is gated by firmware. Enabling Intel VT-x or AMD-V in BIOS/UEFI is therefore the correct next step.

Answer

Enable Secure Boot

Answer

Disable Hyper-Threading

Answer

Update the chipset drivers

Question 14

A user receives an error when trying to access a cloud application: 'This application is not available in your region.' The user is traveling abroad. Which cloud concept is most likely causing this restriction?

Accepted Answer

Geolocation. Geolocation is the cloud concept that restricts access to applications or services based on the user's physical location, often determined by IP address. When a user travels abroad, their IP address changes to one associated with the foreign region, triggering the application's geolocation-based access controls. This is a common mechanism for complying with licensing agreements, data sovereignty laws, or regional content distribution rights. Thus, the error message directly indicates a geolocation restriction.

Answer

High availability

Answer

Multi-tenancy

Answer

Resource pooling

Question 15

A technician is configuring a network for a university campus that has multiple buildings spread across a 5-kilometer area. Each building has its own LAN, and they all need to be interconnected to share resources. Which network type best describes the overall campus network?

Accepted Answer

Campus area network (CAN). A campus area network (CAN) is specifically designed to interconnect multiple LANs within a limited geographic area, such as a university campus or corporate park. With buildings spread across 5 kilometers, the network fits the CAN scope, which typically spans up to 10 km and uses high-speed backbone links like Gigabit Ethernet or fiber optics to connect the individual LANs.

Answer

Local area network (LAN)

Answer

Metropolitan area network (MAN)

Answer

Wide area network (WAN)

Question 16

A technician is troubleshooting a laptop that will not charge via its USB-C port. The laptop uses a USB-C power adapter that works with other devices. The technician tests the port with a known-good USB-C flash drive, and it is not detected. What is the most likely issue?

Accepted Answer

The USB-C port is damaged or has bent pins.. Since the known-good USB-C flash drive is also not detected, the issue is not with the power adapter or its wattage. The port's inability to communicate with any USB-C device indicates a physical hardware fault, such as bent or broken pins inside the port, which prevents both power delivery and data transfer.

Answer

The laptop's battery is completely dead and needs replacement.

Answer

The power adapter is not outputting enough wattage.

Answer

The laptop's BIOS settings have disabled the USB-C port.

Question 17

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 is less prone to electromagnetic interference. Fiber-optic cabling transmits data as pulses of light, making it immune to electromagnetic interference (EMI). This prevents noise and signal degradation that can affect copper-based cable broadband, ensuring consistent low-latency, low-jitter performance for real-time VoIP traffic. While fiber services are often symmetrical, symmetry is a provisioning choice rather than an inherent property of the medium, so EMI immunity is the factor that makes fiber the better choice.

Answer

Fiber has higher download speeds

Answer

Fiber provides symmetrical upload and download speeds

Answer

Fiber is cheaper than cable

Question 18

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

255.255.255.192. The branch office has 30 devices, but the router interface on that subnet also requires an IP address, so at least 31 usable host addresses are needed. A /27 subnet (255.255.255.224) provides only 30 usable addresses (2^5 - 2 = 30), which is not enough once the gateway is counted. A /26 subnet (255.255.255.192) provides 62 usable addresses (2^6 - 2 = 62), which accommodates the 30 devices plus the router with the least waste among the viable options. Therefore, 255.255.255.192 is the correct choice.

Answer

255.255.255.0

Answer

255.255.255.224

Answer

255.255.255.240

Question 19

A technician upgrades a workstation from Windows 10 to Windows 11, but the installation fails with an error that the system does not support TPM 2.0. The CPU is compatible. What must the technician do in UEFI to resolve this?

Accepted Answer

Enable the TPM device in UEFI security settings. Windows 11 requires TPM 2.0. If the CPU is compatible but the installation fails due to TPM, the most likely cause is that the TPM device is disabled in UEFI. Enabling the TPM in UEFI security settings will allow the installation to proceed.

Answer

Enable Secure Boot and set it to Windows UEFI mode

Answer

Disable CSM and set boot mode to UEFI only

Answer

Update the UEFI firmware to the latest version

Question 20

A technician is deploying a cloud-based application that requires a specific operating system and database. The company wants to avoid managing the underlying OS and patches. Which cloud service model should be used?

Accepted Answer

Platform as a Service (PaaS). PaaS provides a managed platform where the provider handles the operating system, runtime, and patching, while the customer deploys and manages only the application and its data. Since the company wants to avoid managing the OS and patches but still deploy a specific application with a database, PaaS fits exactly. The provider manages the underlying infrastructure and OS layers.

Answer

Infrastructure as a Service (IaaS)

Answer

Software as a Service (SaaS)

Answer

Desktop as a Service (DaaS)
