220-1101 Practice Test 23 — 15 Questions

Question 1

A small office network uses a managed switch with port security enabled. A new employee connects their laptop to a configured port, but the laptop cannot obtain an IP address or communicate on the network. The link light on the switch port is on. Other ports in the same VLAN work correctly. Which of the following is the MOST likely cause?

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

Accepted Answer

The switch port has MAC address filtering enabled that does not include the laptop's MAC. Port security with MAC address filtering restricts which devices can communicate through a switch port based on their MAC address. Since the link light is on (Layer 1 is up) but the laptop cannot obtain an IP address or communicate, the switch is likely dropping frames from the laptop's MAC because it is not in the allowed MAC list. This prevents DHCP discovery and all other traffic, even though the physical connection is established.

Answer

The switch port is administratively shut down

Answer

The laptop has a static IP address that conflicts with another device

Answer

The switch port is not in the correct VLAN

Question 2

A user reports that their iPhone 13 does not charge when plugged into the wall outlet using the original charging cable and adapter. The technician tries a different known-good Lightning cable and wall adapter, but the phone still does not charge. The technician inspects the Lightning port on the phone and sees that the port opening appears clean with no visible debris. Which of the following is the BEST next step to troubleshoot this issue?

Accepted Answer

Use a non-conductive tool (e.g., a plastic toothpick) to carefully probe the Lightning port and remove any hidden debris.. The technician's visual inspection may miss compacted debris deep inside the Lightning port. Using a non-conductive tool to gently probe can dislodge hidden lint or dirt that prevents proper contact between the Lightning connector and the port's pins, restoring charging capability without risking a short circuit.

Answer

Reset the network settings to rule out a software conflict affecting charging.

Answer

Connect the phone to a computer and perform a full restore via iTunes.

Answer

Replace the iPhone's battery immediately, as a dead battery is the most likely cause.

Question 3

A small business wants to develop and deploy a custom web application. They do not want to manage any underlying infrastructure, including servers, operating systems, or runtime environments. They want to simply upload their code and let the cloud provider handle scaling and maintenance. Which cloud service model BEST fits this requirement?

Accepted Answer

Platform as a Service (PaaS). Platform as a Service (PaaS) is the correct choice because it provides a complete development and deployment environment in the cloud, abstracting away the underlying infrastructure. The business can upload custom code without managing servers, OS, or runtime, and the cloud provider automatically handles scaling, patching, and maintenance. This directly matches the requirement to avoid infrastructure management while deploying a custom web application.

Answer

Infrastructure as a Service (IaaS)

Answer

Software as a Service (SaaS)

Answer

Anything as a Service (XaaS)

Question 4

A technician is upgrading a desktop PC with a new graphics card that requires two 6-pin PCIe power connectors. The existing power supply unit (PSU) has two 6+2 pin PCIe cables. The technician connects both 6-pin connectors from the cables to the card. The system powers on, but the graphics card is not detected, and its fans spin briefly then stop. The technician has verified that the card is properly seated in the PCIe slot and that the PSU is rated for 500W, which should be sufficient for the system. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The PSU's +12V rail cannot provide enough current for the graphics card under load.. The 6+2 pin PCIe cables are electrically identical to 6-pin connectors when the extra 2 pins are detached, so they are fully compatible. The brief fan spin followed by stop indicates the graphics card is detecting insufficient power delivery, likely because the PSU's +12V rail cannot sustain the required current under load, causing the card's protection circuitry to shut down.

Answer

The 6+2 pin PCIe cables are not designed for the new card's power requirements.

Answer

The graphics card requires a single 12-pin connector, not two 6-pin connectors.

Answer

The motherboard does not have a PCIe x16 slot that supports the card.

Question 5

A network printer is set to a static IP address. Users report that print jobs spool on their workstations but never print. The technician confirms the printer is powered on, the network cable is connected, and the printer's self-test page prints successfully. The technician can ping the printer's IP address from a workstation. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The printer's print queue is paused or the printer is in an 'Offline' state on the print server. The printer is reachable (ping succeeds) and its self-test page prints, confirming basic network connectivity and hardware functionality. The fact that print jobs spool locally but never print indicates the print server is not forwarding jobs to the printer, which is classic behavior when the printer queue is paused or the printer is marked offline on the print server. This prevents the spooler from sending data to the printer even though the network path is intact.

Answer

The printer driver on the workstations is incorrect

Answer

The printer's static IP address conflicts with another device on the network

Answer

The network cable is faulty

Question 6

A user accidentally spills coffee over their smartphone. They immediately pick it up and wipe the exterior. The phone is still powered on and functioning, but the touchscreen is not responding correctly in the area where the liquid was spilled. Which of the following should the user do FIRST to prevent further damage?

Accepted Answer

Power off the phone and remove the battery if possible.. Powering off the phone and removing the battery (if possible) immediately stops electrical current from flowing through the device, which prevents short circuits and electrochemical corrosion caused by the conductive and corrosive nature of coffee. This is the first and most critical step to mitigate damage to the motherboard and other internal components.

Answer

Place the phone in a bag of uncooked rice for 24 hours.

Answer

Use a hairdryer on high heat to dry the phone.

Answer

Continue using the phone and hope it dries out naturally.

Question 7

A systems administrator is planning to deploy a critical application to the cloud. The application requires dedicated physical hardware to meet compliance standards. The administrator also needs full control over the operating system, including kernel configurations. Which cloud service model BEST meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS) with dedicated hosts. Infrastructure as a Service (IaaS) with dedicated hosts is the correct choice because it provides the administrator with dedicated physical hardware, ensuring compliance with standards that require no multi-tenancy, and full control over the operating system, including kernel configurations. Unlike shared IaaS, dedicated hosts guarantee that the underlying physical server is not shared with other tenants, meeting strict compliance and performance requirements.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Function as a Service (FaaS)

Question 8

A technician is troubleshooting a desktop computer that cannot access the internet. The computer is configured with a static IP address of 10.0.0.15, subnet mask 255.255.255.0, and default gateway 10.0.0.1. The technician can ping the default gateway successfully but cannot ping the public IP address 8.8.8.8. Other devices on the same network can access the internet normally. Which of the following is the MOST likely cause?

Accepted Answer

A firewall on the computer is blocking outbound traffic. The computer can ping the default gateway (10.0.0.1) successfully, which confirms that Layer 2 and Layer 3 connectivity to the local network is working, and the static IP configuration is correct. Since other devices on the same network can access the internet normally, the issue is isolated to this specific computer. A local firewall (e.g., Windows Defender Firewall) blocking outbound ICMP or TCP traffic to public IPs like 8.8.8.8 would prevent internet access while still allowing local subnet communication, making option C the most likely cause.

Answer

The DHCP server is not functioning

Answer

The default gateway is not configured correctly on the computer

Answer

The network cable is faulty

Question 9

A company wants to deploy a custom web application that includes a custom database and a web server with specific modules. The development team needs full control over the operating system, including the ability to apply security patches and install third-party software. The company does not want to manage the physical servers, hypervisors, or network infrastructure. The cloud provider will be responsible for the underlying hardware and virtualization layer. Which cloud service model BEST meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, giving the customer full control over the operating system, including the ability to apply security patches and install third-party software. The cloud provider manages the physical servers, hypervisors, and network infrastructure, while the customer retains administrative access to the OS, which is essential for deploying a custom web application with a custom database and specific modules.

Question 10

A user reports that their smartphone will not charge when connected to a known-good charger and cable. The technician examines the charging port and sees debris inside. Which of the following tools should the technician use to safely remove the debris?

Accepted Answer

A wooden toothpick. A wooden toothpick is non-conductive and non-abrasive, making it safe to dislodge debris from a smartphone charging port without risking short circuits or damaging the delicate pins inside the USB-C or Lightning connector. Metal tools can cause electrical shorts or scratch the port's contacts, while compressed air may push debris deeper, and alcohol with a cotton swab can leave fibers or moisture that interfere with charging.

Answer

A metal paperclip

Answer

A can of compressed air

Answer

Isopropyl alcohol and a cotton swab

Question 11

A user reports that their workstation intermittently loses network connectivity. The technician checks the IP configuration during an outage and finds the IP address is 169.254.12.34. The network uses DHCP, and other workstations on the same subnet are functioning normally. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The network cable is either faulty or not fully seated.. The 169.254.x.x address is an Automatic Private IP Addressing (APIPA) address, assigned by the OS when DHCP fails. Since other workstations on the same subnet are working, the DHCP server and switch port are functional, isolating the issue to the local link. A faulty or loose cable can cause intermittent connectivity, leading to DHCP discovery failures and APIPA assignment.

Answer

The DHCP server has run out of IP addresses.

Answer

The network switch port is administratively shut down.

Answer

The workstation's network adapter driver is corrupted.

Question 12

A user wants to connect their smartphone to an external monitor for a presentation. The monitor only has a VGA input, and the smartphone has a USB-C port that supports DisplayPort Alt Mode. Which cable or adapter should the user obtain to connect the devices?

Accepted Answer

USB-C to VGA adapter. The monitor only has a VGA input, which is an analog video interface. The smartphone's USB-C port supports DisplayPort Alt Mode, which can output a digital DisplayPort signal. A USB-C to VGA adapter contains a digital-to-analog converter (DAC) that converts the DisplayPort signal from the phone into an analog VGA signal compatible with the monitor.

Answer

USB-C to HDMI adapter

Answer

USB-C to DisplayPort cable

Answer

Thunderbolt 3 to VGA cable

Question 13

A user reports that their smartphone will charge wirelessly on a charging pad but will not charge when connected to a USB-C cable. The cable and charger have been tested on another phone and work normally. The technician has already performed a forced restart and cleaned the charging port with compressed air. Which component should the technician replace FIRST?

Accepted Answer

Charging port flex cable / charge port assembly. The charging port flex cable / charge port assembly is the most likely culprit because wireless charging works (bypassing the port entirely) but wired USB-C charging fails, even though the cable and charger are proven good on another device. This isolates the fault to the physical port or its internal flex cable connection, which is a common failure point due to wear, debris, or damage that compressed air cannot resolve.

Answer

Battery

Answer

Main board / motherboard

Answer

USB controller chip

Question 14

A user reports that their Android smartphone's screen is shattered and the lower half of the touchscreen is unresponsive. The phone is locked with a PIN, and the user urgently needs to retrieve photos from the internal storage. The user does not want to spend money on repairs if possible. Which of the following is the BEST method to retrieve the data?

Accepted Answer

Use a USB OTG adapter to connect a wired mouse. A USB OTG (On-The-Go) adapter allows you to connect a wired mouse to the Android smartphone. Once connected, the mouse cursor can navigate the locked screen, enter the PIN, and access the internal storage without requiring the broken touchscreen to function. This method is cost-free (assuming the user has or can borrow an OTG adapter and mouse) and does not involve any repair or data loss.

Answer

Connect the phone to a computer via USB cable and access the files using MTP

Answer

Replace the phone's screen digitizer

Answer

Perform a factory reset to restore touch functionality

Question 15

A cloud administrator configures a virtual machine so that it automatically increases its allocated CPU and RAM resources during peak demand and reduces them during low usage periods without any manual intervention. Which cloud computing characteristic does this configuration BEST represent?

Accepted Answer

Elasticity. Elasticity is the cloud characteristic that enables automatic scaling of resources (CPU, RAM) up and down in response to demand, without manual intervention. This configuration specifically matches elasticity because it adjusts resources dynamically during peak and low usage periods, which is distinct from the broader planning capability of scalability.

Answer

Scalability

Answer

Resource pooling

Answer

Metered service
