220-1201 Practice Test 21 — 15 Questions

Question 1

A company uses a PaaS provider to deploy a custom web application. After an update, the application fails to start. The developer checks the code and finds no errors. What is the most likely cause of the failure?

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

Accepted Answer

The PaaS provider updated the runtime environment, breaking compatibility. In PaaS, the provider manages the runtime environment, including dependencies and configuration. An update may have changed the underlying platform (e.g., runtime version, library) that the application relies on, causing incompatibility. The developer's code is fine, so the issue is environmental.

Answer

The developer's local machine has a different operating system

Answer

The application's database connection string is incorrect

Answer

The cloud provider's physical server has a hardware fault

Question 2

A user's all-in-one PC has a touchscreen that is not responding correctly. The technician calibrates the touchscreen, but the issue persists. The technician then notices that the screen is slightly misaligned with the bezel. What is the most likely cause?

Accepted Answer

The LCD panel has shifted inside the chassis.. The physical misalignment between the screen and the bezel indicates that the LCD panel has physically shifted inside the chassis, which is a common issue in all-in-one PCs where the panel is mounted directly to the frame. This shift causes the touch input coordinates to be offset from the display output, and recalibration cannot compensate for a hardware displacement. The digitizer (touch sensor) is likely still functional, but its alignment relative to the LCD is now incorrect.

Answer

The touchscreen driver is corrupted.

Answer

The digitizer is failing.

Answer

The operating system needs a touchscreen firmware update.

Question 3

A user says their inkjet printer prints colors that are slightly misaligned, with text appearing blurry. The printer has been used heavily for months. Which component should be checked or calibrated first?

Accepted Answer

The printhead alignment. Misaligned colors and blurry text on an inkjet printer typically indicate that the printhead alignment is off. Most inkjet printers have a built-in alignment utility that prints a test page and adjusts the printhead position. Running this calibration is the standard first step.

Answer

The ink cartridge nozzles

Answer

The paper type setting

Answer

The printer driver version

Question 4

A user reports that they can receive emails but cannot send any. The email client is configured with SMTP on port 25. The IT team confirms that port 25 is blocked by the ISP. Which alternative port should be used for SMTP submission?

Accepted Answer

Port 587. Port 587 is the standard SMTP submission port defined in RFC 6409 for email clients to send outgoing mail. Unlike port 25, which is used for SMTP relay between mail servers and is often blocked by ISPs to prevent spam, port 587 is specifically designated for client-to-server submission and typically supports STARTTLS encryption. Using port 587 bypasses the ISP's block on port 25 while adhering to modern email security practices.

Answer

Port 110

Answer

Port 143

Answer

Port 993

Question 5

A small business wants to connect two separate office buildings that are 150 meters apart, with no existing data cabling between them. They need a reliable, high-speed connection without running new cables. Which type of network should be implemented?

Accepted Answer

Local Area Network (LAN). A Local Area Network (LAN) is the most appropriate classification. While typically confined to a single building or a small campus, a LAN can be extended to connect two nearby buildings, such as those 150 meters apart, especially when using wireless bridges. This provides a reliable, high-speed connection without the need for new physical cabling. A MAN typically covers a much larger geographic area (several kilometers), and a WAN covers even larger distances. A PAN is for very short-range personal device connections.

Answer

Personal Area Network (PAN)

Answer

Wide Area Network (WAN)

Answer

Metropolitan Area Network (MAN)

Question 6

A user reports that their RAID 5 array with three 2 TB drives is missing one drive in the RAID configuration utility. The technician finds that the missing drive is not detected by the system BIOS. What should the technician do next?

Accepted Answer

Check the SATA cable and power connection to the missing drive.. If a drive is not detected in BIOS, the issue is at the hardware level—cable, power, or drive failure. The next step is to check connections. This tests systematic troubleshooting of RAID hardware.

Answer

Initialize the missing drive in Disk Management.

Answer

Replace the RAID controller.

Answer

Rebuild the array using the remaining two drives.

Question 7

A technician is configuring an MFP for a healthcare clinic that must comply with HIPAA. The MFP has a built-in hard drive that stores scanned documents. The clinic wants to ensure that once a document is scanned and transmitted, it cannot be recovered from the MFP's drive. What feature should the technician enable?

Accepted Answer

Secure erase after transmission. Secure erase (or data overwrite) is a feature that overwrites the hard drive with patterns of data to prevent recovery. This is critical for compliance in environments like healthcare where patient data must be protected after use.

Answer

User authentication with PIN

Answer

Secure print release

Answer

Hard drive encryption

Question 8

A technician is configuring a dual-monitor setup for a stock trader. The primary monitor is a 27-inch 1440p display connected via DisplayPort, and the secondary is a 24-inch 1080p display connected via HDMI. The user notices that windows dragged to the secondary monitor appear stretched. What is the most likely cause?

Accepted Answer

The secondary monitor's resolution is set to 1440p instead of 1080p. When a 1080p monitor is configured to run at 1440p, the graphics card scales the image to fit the physical panel, but the pixel density mismatch causes stretching and blurriness. The secondary monitor's native resolution is 1920x1080, so setting it to 2560x1440 forces non-native scaling, distorting the image. This is the most common cause of stretched windows in a multi-monitor setup with different native resolutions.

Answer

The HDMI cable is not version 2.0 or higher

Answer

The graphics card cannot support two different resolutions

Answer

The secondary monitor is set to extend mode instead of duplicate

Question 9

A technician is troubleshooting a Samsung Galaxy tablet that has a cracked screen but still responds to touch. The user wants to transfer data to a new tablet. The technician connects the tablet to a PC via USB, but the PC does not recognize the device. What is the most likely reason?

Accepted Answer

The tablet is in USB charging-only mode and cannot be changed due to the cracked screen. When a device's screen is cracked, the digitizer may still work, but the user might not be able to change USB settings from 'Charging only' to 'File transfer' if the touch input is needed for that selection. This is a common scenario where the default USB mode prevents data access.

Answer

The USB cable is defective

Answer

The tablet's USB port is damaged from the drop

Answer

The PC lacks the proper Samsung USB drivers

Question 10

A small business reports that employees can access the internet but cannot reach the internal company website hosted on a local server. The server's IP address is 192.168.1.10, and clients use DHCP. What is the most likely cause?

Accepted Answer

The DNS server lacks a host record for the internal website.. The internal website is accessed by its hostname, which clients resolve via DNS. Since employees can reach the internet (so general DNS works) but not the local server, the most likely cause is that the DNS server lacks a host record (A or AAAA record) for the internal website's name, preventing name-to-IP resolution for 192.168.1.10. DHCP is functioning correctly because clients receive IP addresses and can access the internet.

Answer

The DHCP server is not assigning the correct subnet mask.

Answer

The switch port connecting the server is administratively down.

Answer

The firewall is blocking port 443 inbound.

Question 11

A user's iPhone 14 cannot make or receive calls, but can send iMessages and use the internet. The user has not changed any settings recently. What is the most likely cause?

Accepted Answer

The carrier settings need to be updated.. The ability to send iMessages and use the internet indicates that the device has a working data connection (cellular or Wi-Fi), but the inability to make or receive calls points to a problem with the carrier-specific settings that control voice services. Carrier settings updates are pushed by the carrier to configure network parameters such as APN, MMS, and voice-over-LTE (VoLTE) settings; if these are outdated or corrupted, voice calls may fail while data services remain functional. Since the user has not changed any settings, an automatic or pending carrier settings update is the most likely cause, as it can resolve mismatches between the device and the carrier's network.

Answer

The phone is in Airplane Mode.

Answer

The SIM card is damaged.

Answer

The phone's microphone is broken.

Question 12

A user reports that they can only access the internet intermittently. The technician runs ipconfig and sees an IPv4 address of 192.168.1.105 with a subnet mask of 255.255.255.0 and a default gateway of 192.168.1.1. The technician pings the gateway successfully, but pings to 8.8.8.8 fail. What is the most likely issue?

Accepted Answer

The router's WAN connection is down or misconfigured.. The technician can ping the local gateway (192.168.1.1) successfully, which confirms that Layer 2 and Layer 3 connectivity within the local subnet is working and that the user's IP configuration is valid. However, pings to the public DNS server 8.8.8.8 fail, indicating that traffic cannot reach the internet. Since the gateway is reachable but external IPs are not, the most likely cause is that the router's WAN connection is down or misconfigured, preventing traffic from being routed beyond the local network.

Answer

The user's computer has a duplicate IP address.

Answer

The DNS server is not resolving addresses.

Answer

The user's firewall is blocking ICMP traffic.

Question 13

A user complains that their internet is slow in the evenings, especially when streaming video. They have a cable modem and a wireless router. What is the most likely cause?

Accepted Answer

Network congestion due to many users sharing the same cable node.. C is correct because cable internet uses a shared coaxial cable node, and during peak evening hours, many subscribers in the same neighborhood are actively using the connection. This shared bandwidth leads to contention and reduced throughput, especially for high-bandwidth activities like streaming video, which is a classic symptom of node congestion rather than a local issue.

Answer

The wireless router is outdated.

Answer

The ISP is throttling streaming traffic.

Answer

Interference from other wireless networks.

Question 14

During a network upgrade, a technician needs to document the physical path a cable takes from a workstation to the patch panel in the server room. Which tool is specifically designed to trace the exact cable route through walls and ceilings?

Accepted Answer

Toner and probe. A toner and probe (often called a fox and hound) is specifically designed to trace the physical path of a cable through walls, ceilings, and conduits. The toner injects an analog audio signal onto the cable, and the inductive probe detects that signal without needing a direct electrical connection, allowing the technician to follow the cable's route even when it is hidden behind building materials.

Answer

Cable tester

Answer

Crimper

Answer

Punch-down tool

Question 15

A user wants to connect their smartphone to a car's stereo system that only has an auxiliary input (3.5mm jack). The smartphone has a USB-C port and no headphone jack. Which accessory is required?

Accepted Answer

A USB-C to 3.5mm adapter.. The car stereo only has a 3.5mm auxiliary input, so the smartphone's audio output must be converted to analog audio. A USB-C to 3.5mm adapter contains a digital-to-analog converter (DAC) that converts the smartphone's digital audio signal into an analog signal that the car stereo can accept through the 3.5mm jack.

Answer

A USB-C to USB-A cable.

Answer

A Bluetooth FM transmitter.

Answer

A 3.5mm extension cable.
