220-1201 Practice Test 47 — 15 Questions

Question 1

A customer reports that their new NVMe SSD is not detected by the system, even though it is properly seated. The motherboard supports both UEFI and legacy BIOS. Which firmware setting should be enabled to ensure the NVMe drive is recognized?

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

Accepted Answer

Enable UEFI boot mode and disable CSM. NVMe SSDs require UEFI boot mode to be recognized by the system, as they are not supported in legacy BIOS mode. Enabling UEFI boot mode and disabling Compatibility Support Module (CSM) ensures that the system uses native UEFI firmware, which includes NVMe drivers, allowing the drive to be detected.

Answer

Enable Legacy BIOS mode

Answer

Enable Secure Boot

Answer

Enable SATA hot-plug

Question 2

A technician is setting up a network for a university campus that spans several buildings across a 2-kilometer area. The network must support both wired and wireless connections for thousands of users. Which network type best describes this setup?

Accepted Answer

Campus Area Network (CAN). A Campus Area Network (CAN) is specifically designed to interconnect multiple buildings within a limited geographic area, such as a university campus or corporate park, typically spanning up to a few kilometers. This setup requires high-speed backbone links (often fiber optic) to support thousands of users with both wired and wireless access, which aligns perfectly with the CAN definition.

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)

Answer

Metropolitan Area Network (MAN)

Question 3

A user wants to add a second hard drive to their desktop for extra storage, but the computer only has one SATA data cable available. The technician has an extra SATA power cable from the power supply. What is the most practical solution?

Accepted Answer

Purchase an additional SATA data cable and use the existing power cable.. A SATA data cable carries data only; power is delivered separately via a SATA power connector from the PSU. Since the technician already has a spare SATA power cable and the only missing item is a data cable, the correct fix is to buy an additional SATA data cable and connect the second drive using the existing power cable. This is the standard, low-cost, and non-destructive solution for adding an internal drive.

Answer

Use a Y-splitter on the existing SATA data cable to connect both drives.

Answer

Connect the second drive using an external USB-to-SATA adapter.

Answer

Replace the existing hard drive with a larger one.

Question 4

A user complains that their laptop, which has 8 GB of RAM soldered on the motherboard, is running slowly when multitasking. They ask if they can add more RAM. The laptop has one empty SO-DIMM slot. What is the best recommendation?

Accepted Answer

Recommend adding a SO-DIMM module of the same type and speed as the soldered RAM.. The laptop has soldered RAM but also one empty SO-DIMM slot. Adding a compatible SO-DIMM module (same type and speed) will increase total RAM and improve multitasking performance. This is the best recommendation because it leverages the available slot without requiring laptop replacement.

Answer

Advise the user to replace the laptop because soldered RAM cannot be upgraded.

Answer

Suggest removing the soldered RAM and replacing it with a larger module.

Answer

Tell the user to install two SO-DIMM modules for dual-channel.

Question 5

A user complains that they can browse the internet but cannot access network shares on a file server by hostname, though they can access them by IP address. The DNS server is responding to queries for other domains. Which protocol is most likely malfunctioning?

Accepted Answer

NetBIOS. The user can access network shares by IP address but not by hostname, which indicates a name resolution failure specific to NetBIOS. NetBIOS over TCP/IP (NBT) is responsible for resolving NetBIOS names (used for file and printer sharing on Windows networks) to IP addresses. Since DNS works for other domains but not for the file server's hostname, the issue is likely with NetBIOS name resolution, not DNS.

Answer

HTTP

Answer

DHCP

Answer

ARP

Question 6

A network administrator is troubleshooting a connectivity issue between two servers. Server A has IP 192.168.10.25/25, and Server B has IP 192.168.10.200/25. Server A can ping its default gateway (192.168.10.1) but cannot ping Server B. What is the most likely cause?

Accepted Answer

The servers are on different subnets and require a router to communicate.. Server A (192.168.10.25/25) has a subnet mask of 255.255.255.128, placing it in the 192.168.10.0/25 subnet (range 0–127). Server B (192.168.10.200/25) is in the 192.168.10.128/25 subnet (range 128–255). These are different subnets, so Server A cannot reach Server B directly via Layer 2; a router (or Layer 3 switch) is required to forward traffic between them. The fact that Server A can ping its default gateway (192.168.10.1) confirms its IP and mask are correctly configured for its own subnet.

Answer

Server A has a duplicate IP address.

Answer

The subnet mask is incorrect on one of the servers.

Answer

The default gateway is misconfigured.

Question 7

A company has two branch offices in different cities. They need to connect their LANs so employees can access resources at both locations securely over the internet. Which network type should be used?

Accepted Answer

Wide Area Network (WAN). A Wide Area Network (WAN) is the correct choice because it connects geographically separated LANs across a large distance, such as between two cities, using public or private infrastructure like the internet. WAN technologies, such as MPLS, leased lines, or IPsec VPNs, provide secure, encrypted tunnels over the internet to ensure data confidentiality and integrity between the branch offices.

Answer

Local Area Network (LAN)

Answer

Metropolitan Area Network (MAN)

Answer

Personal Area Network (PAN)

Question 8

A user's smartphone can send and receive text messages but cannot access the internet over cellular data. Wi-Fi internet works fine. Which setting is most likely misconfigured?

Accepted Answer

The APN settings are incorrect.. The APN (Access Point Name) defines the gateway between the mobile network and the internet. If the APN settings are incorrect or missing, the device can still register on the cellular network for voice and SMS (which use the control plane) but cannot establish a data session (user plane) because the packet data network gateway cannot be reached. Wi-Fi internet works fine because it bypasses the cellular data path entirely.

Answer

The Wi-Fi hotspot is enabled.

Answer

Bluetooth is turned on.

Answer

The device is in roaming mode.

Question 9

A technician is upgrading a workstation and notices that the new CPU is not listed in the motherboard's supported CPU list. The motherboard uses an LGA 1200 socket. What is the most likely issue?

Accepted Answer

The motherboard's chipset does not support that CPU generation. LGA 1200 is a physical socket used by Intel's 10th and 11th generation Core processors, but the socket alone does not guarantee CPU support — the motherboard chipset (e.g., H410, B460, Z490, H510, B560, Z590) determines which CPU generations are compatible. If the CPU is not on the QVL (Qualified Vendor List), the chipset likely does not support that generation, even though it physically fits.

Answer

The CPU is physically too large for the socket

Answer

The CPU requires more power than the motherboard can provide

Answer

The CPU is a server-grade processor not meant for workstations

Question 10

A company's web server is accessible from the internet, but users report that they cannot upload files to it using a web browser. The server is configured to allow file uploads via HTTP. Which protocol is most likely being blocked by the firewall?

Accepted Answer

HTTP. The question states that the server is configured to allow file uploads via HTTP, yet users cannot upload files using a web browser. Since HTTP (port 80) is the protocol used for web browser uploads, the firewall is most likely blocking HTTP traffic. If HTTP were allowed, the uploads would succeed; the symptom points directly to HTTP being blocked.

Answer

HTTPS

Answer

FTP

Answer

SMTP

Question 11

A technician is troubleshooting a VoIP phone that cannot register with the call server. The phone has a valid IP address and can ping the call server by IP. Which protocol is most likely not functioning correctly?

Accepted Answer

SIP. The phone has a valid IP address and can ping the call server by IP, which confirms that Layer 3 connectivity and DHCP are working. However, the phone cannot register with the call server, which requires the Session Initiation Protocol (SIP) to exchange registration messages (REGISTER request and 200 OK response). If SIP is misconfigured, blocked by a firewall, or the SIP proxy is unreachable, registration will fail even though basic IP connectivity exists.

Answer

RTP

Answer

DHCP

Answer

DNS

Question 12

A user scans a document to a USB drive attached to the multifunction printer, but the file is saved as a TIFF image instead of a searchable PDF. The user needs the text to be selectable. What should the technician do?

Accepted Answer

Enable OCR in the printer's scan settings and select 'Searchable PDF' as the output format.. A TIFF scan is a pure image with no text layer, so the text is not selectable. Enabling OCR in the printer's scan settings and choosing 'Searchable PDF' as the output format runs optical character recognition on the scanned image and embeds an invisible text layer behind the image, making the text selectable and searchable. This directly solves the user's requirement without changing hardware or workflow.

Answer

Change the scan file format to JPEG.

Answer

Increase the scan resolution to 1200 DPI.

Answer

Save the file to a network folder instead of USB.

Question 13

A user wants to print a high-resolution photo on glossy paper using an inkjet printer. After printing, the colors appear washed out and the photo has a grainy appearance. The printer is set to 'normal' quality and 'plain paper' in the driver. What should the technician change to improve the output?

Accepted Answer

Change the paper type to 'glossy photo paper' and the print quality to 'best' or 'photo'.. Inkjet print quality is governed primarily by the driver's media type and quality settings, which control ink droplet size, print head passes, and ink volume. Setting the paper type to 'glossy photo paper' tells the driver to use the correct ink formulation and drying profile, while 'best' or 'photo' quality increases resolution and print head passes, eliminating the washed-out, grainy look.

Answer

Replace the ink cartridges with high-yield cartridges.

Answer

Calibrate the printer using the built-in utility.

Answer

Use a different brand of glossy paper.

Question 14

A user complains that their Android tablet's touchscreen is unresponsive in a vertical strip down the middle of the screen, but the rest of the screen works fine. They have restarted the device and removed the screen protector. What is the most likely cause?

Accepted Answer

The digitizer is damaged.. A dead or unresponsive vertical strip on a touchscreen, with the rest of the screen working and after restarting and removing the screen protector, points to physical damage to the digitizer — the transparent layer that senses touch. The digitizer has a grid of sensors; damage to a specific region (often from a drop or pressure) creates a dead zone that no software fix can resolve. Replacing the digitizer (or the display assembly) is the correct repair.

Answer

A software glitch in the touchscreen driver.

Answer

The screen protector is causing interference.

Answer

The LCD panel is failing.

Question 15

During a printer deployment, a technician installs a network laser printer and configures it with a static IP address. Users can print from their computers, but the printer's web interface is unreachable from any browser. What is the most likely cause?

Accepted Answer

The printer's embedded web server is disabled. If users can print successfully but the printer's web interface is unreachable, the most likely cause is that the printer's embedded web server (EWS) is disabled. Many network printers have an option in the control panel or configuration menu to enable/disable the web server for security reasons. When disabled, the printer still responds to print jobs (via IPP, LPD, or raw port 9100) but does not serve HTTP/HTTPS pages. This matches the symptom of printing working while the web UI is inaccessible.

Answer

The printer's IP address is on a different subnet

Answer

The printer driver is outdated

Answer

The printer's firmware needs updating
