220-1101 Practice Exam 61 — 20 Questions

Question 1

A workstation with a static IP address of 192.168.1.10/24 can ping its default gateway (192.168.1.1) and other workstations on the same subnet. However, it cannot ping any device on a different subnet (e.g., 10.0.0.1) nor access the internet. Other workstations on the same subnet can ping the same remote device and access the internet without issue. The technician has verified the workstation's IP configuration is correct. Which of the following is the MOST likely cause?

Accepted Answer

The router's ACL or firewall is blocking the workstation's IP address from accessing other networks.. Since the workstation can ping its default gateway and other local hosts but cannot reach remote subnets or the internet, the issue is not with the local IP configuration or the gateway's reachability. The fact that other workstations on the same subnet can access remote networks points to a policy or filtering mechanism on the router that specifically blocks traffic from this workstation's IP address. This is most commonly implemented via a router ACL or firewall rule that denies traffic from 192.168.1.10 to other networks.

Answer

The workstation's firewall is blocking all traffic to remote subnets.

Answer

The default gateway IP address is misconfigured on the workstation.

Answer

The subnet mask is incorrect.

Question 2

A user's smartphone has a cracked screen but the display and touch still function. The user wants to transfer all data, including contacts, photos, and app settings, to a new phone of the same brand. Which method would be MOST efficient and complete?

Accepted Answer

Use the manufacturer's migration app on both phones. The manufacturer's migration app (e.g., Samsung Smart Switch, Google Pixel Migrate) is designed to transfer all data—including contacts, photos, app settings, and even home screen layouts—over a direct Wi-Fi or wired connection. This method is the most efficient and complete because it captures app data and system settings that cloud backups or file copies often miss, and it works without needing the cracked screen to be fully usable for complex operations.

Answer

Back up to the cloud and restore on the new phone

Answer

Copy files to a microSD card and insert it into the new phone

Answer

Transfer contacts and photos via Bluetooth

Question 3

An employee connects their laptop to the company network via Ethernet. They can access the internet but cannot connect to internal servers using their hostnames (e.g., \fileserver). They can ping internal server IPs. The network uses an internal DNS server at 192.168.1.5. The technician checks the laptop's network adapter settings and sees that the DNS server is manually set to 8.8.8.8. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The laptop is configured to use a public DNS server instead of the internal DNS server.. The laptop can access the internet and ping internal servers by IP, confirming that basic IP connectivity and routing are functional. However, it cannot resolve internal hostnames because its DNS server is manually set to 8.8.8.8 (a public Google DNS server), which does not have records for the company's internal domain. The internal DNS server at 192.168.1.5 is required to resolve names like \fileserver, so using an external DNS server breaks internal name resolution.

Answer

The laptop's IPv4 address is outside the company's subnet.

Answer

The DNS resolver cache on the laptop is corrupted.

Answer

The internal DNS server is not responding to queries from different subnets.

Question 4

A technician wants to set up a virtualization lab on a laptop running Windows 10 to test different operating systems. The laptop has 16GB of RAM. Which type of hypervisor is MOST appropriate for this scenario?

Accepted Answer

Type 2 (hosted) hypervisor. A Type 2 (hosted) hypervisor runs as a software layer on top of an existing operating system (Windows 10 in this case). It is the most appropriate choice for a laptop lab because it allows the technician to use the host OS for daily tasks while running virtual machines for testing different operating systems. Type 2 hypervisors like VMware Workstation or VirtualBox are designed for client hardware and do not require dedicated server-class resources.

Answer

Type 1 (bare-metal) hypervisor

Answer

Container-based virtualization

Answer

Cloud-based virtualization service

Question 5

A desktop powers on but repeatedly shuts down under load. The CPU temperature rises quickly even after dust is removed from the case. What should the technician inspect next?

Accepted Answer

CPU heatsink seating and thermal paste application. The CPU temperature rising quickly under load, even after dust removal, indicates that the heatsink is not making proper contact with the CPU or the thermal interface material has degraded. Inspecting the CPU heatsink seating and thermal paste application is the correct next step because poor thermal transfer causes the CPU to reach its thermal throttle or shutdown threshold, triggering a protective shutdown. This is a classic hardware troubleshooting step for overheating-related intermittent shutdowns.

Answer

The keyboard layout

Answer

The Windows user profile

Answer

The monitor cable type

Question 6

A technician is setting up a small office network with a managed switch, a router (192.168.1.1/24), and 20 workstations. All workstations are connected to the switch and configured with static IPs in the range 192.168.1.2-192.168.1.21, subnet mask 255.255.255.0, default gateway 192.168.1.1. All workstations can ping the router successfully, but some workstations cannot ping each other. Which of the following is the MOST likely cause?

Accepted Answer

A. The most likely cause is that the managed switch has VLANs configured, separating workstations into different broadcast domains. Even though all workstations are on the same IP subnet (192.168.1.0/24), if they are assigned to different VLANs, the switch will not forward frames between them unless a router or Layer 3 switch is configured for inter-VLAN routing. Since the workstations can reach the router (which may be on a trunk or access port in a specific VLAN), but not each other, this points to VLAN segmentation as the root cause.

Answer

B

D

Question 7

A user reports that their smartphone's battery drains significantly faster than usual, and the device feels warm to the touch even when it is not being actively used. The battery is not swollen. Which of the following is the MOST likely cause of these symptoms?

Accepted Answer

Background app malfunction causing high CPU usage. A background app malfunction causing high CPU usage forces the processor to draw more power, generating excess heat even when the device is idle. This directly explains both the rapid battery drain and the warmth, as the CPU remains active without user interaction.

Answer

Faulty charging port

Answer

Defective display assembly

Answer

Weak cellular signal

Question 8

A technician is troubleshooting a desktop PC that freezes for several seconds during disk-intensive operations, such as transferring large files. The technician has already replaced the hard drive with an SSD, tested the RAM with a memory diagnostic tool (no errors), and updated the chipset drivers. The issue still occurs. Which of the following is the MOST likely remaining cause of the freezes?

Accepted Answer

A faulty SATA cable. A faulty SATA cable can cause intermittent connectivity issues that manifest as system freezes during disk-intensive operations. Even after replacing the hard drive with an SSD and verifying RAM and drivers, a degraded or loose SATA cable can introduce data transfer errors or link drops, forcing the system to retry commands and causing pauses. This is the most likely remaining cause because the cable is the only component in the data path not yet replaced or tested.

Answer

Overheating CPU

Answer

Incompatible RAM speed

Answer

Outdated network drivers

Question 9

A user drops their smartphone onto a concrete floor. After the fall, the screen displays images and colors correctly, but the touch input does not respond at all. The user has rebooted the phone and wiped the screen clean. Which of the following hardware components is MOST likely damaged?

Accepted Answer

B. The digitizer is the layer of the touchscreen that detects touch input. Since the display (LCD/OLED) still shows images and colors correctly, the digitizer is the most likely component damaged from the drop, as it is a separate, fragile layer bonded to the glass.

Answer

A

Answer

C

Answer

D

Question 10

A technician is replacing a failed power supply in a desktop computer. The new power supply is the same form factor and wattage as the original. After installing it, the computer powers on for a few seconds then shuts down. The technician has already verified that all power connectors are securely attached and that the power supply passes the paperclip test when disconnected from the motherboard. Which of the following should the technician check NEXT?

Accepted Answer

The CPU fan is connected to the correct header.. The symptom of powering on for a few seconds then shutting down is classic for a CPU thermal or fan failure protection mechanism. Even though the power supply passes the paperclip test, the motherboard's CPU fan header must detect a tachometer signal from the fan; if the fan is connected to a different header (e.g., chassis fan), the motherboard may assume the CPU fan has failed and trigger an immediate shutdown to prevent overheating.

Answer

The power supply voltage selector switch.

Answer

The motherboard's capacitors for bulging.

Answer

The RAM modules are seated properly.

Question 11

A small office uses a single unmanaged switch to connect 20 computers. Users report that file transfers between computers are very slow, and the network feels sluggish. The technician notices that the switch's collision LED is blinking frequently. Which of the following is the MOST likely cause of this issue?

Accepted Answer

A duplex mismatch between the switch and one or more connected devices. A duplex mismatch occurs when one device is set to full-duplex and the other to half-duplex, causing the half-duplex device to detect collisions when the full-duplex device transmits without checking for a clear channel. The frequent collision LED on an unmanaged switch indicates that collisions are occurring, which is a classic symptom of duplex mismatch, as the switch and workstation negotiate incorrectly or are manually misconfigured.

Answer

An excessive number of broadcast packets flooding the network

Answer

A malfunctioning NIC on one of the workstations

Answer

An incorrect VLAN configuration on the switch

Question 12

A company hosts a critical database on a virtual machine (VM) in a public cloud IaaS environment. The database requires high IOPS and low latency. The data must persist even if the VM is stopped or terminated. Additionally, the administrator needs to take frequent snapshots for backup. Which of the following storage types should be used for the database VM?

Accepted Answer

Block storage. Block storage (e.g., AWS EBS, Azure Managed Disks) provides raw, low-latency volumes that can be attached to a VM, supporting high IOPS for database workloads. Data persists independently of the VM lifecycle—even if the VM is stopped or terminated—and snapshots can be taken for backup. This makes block storage the correct choice for a critical database requiring persistence and frequent snapshots.

Answer

Object storage

Answer

File storage

Answer

Ephemeral storage

Question 13

A technician is installing a PoE security camera that is located 85 meters (279 feet) from the network switch. The switch does not support Power over Ethernet (PoE). The camera requires both data connectivity and power over the same Ethernet cable. Which of the following is the best solution?

Accepted Answer

Use a PoE injector at the switch location. A PoE injector at the switch location is the best solution because it adds power to the Ethernet cable without requiring a PoE switch. The camera is 85 meters away, which is within the 100-meter maximum for Ethernet (Cat 5e/6), so the existing cabling can carry both data and power when a PoE injector is used. This provides a cost-effective, single-cable solution for both connectivity and power.

Answer

Use a PoE power supply connected directly to the camera

Answer

Replace the existing cable with Cat 6a cabling

Answer

Use fiber optic cable with media converters at each end

Question 14

A technician is installing a new graphics card into a desktop computer. The graphics card requires a 6-pin PCIe power connector, but the power supply only has a 4-pin Molex peripheral connector available. The technician has access to various adapter cables. Which of the following adapters would allow the technician to power the graphics card? (Select TWO).

Accepted Answer

4-pin Molex to 6-pin PCIe power adapter. Option A is correct because a 4-pin Molex to 6-pin PCIe power adapter converts the +12V and ground from a standard peripheral connector into the required PCIe power pinout, allowing the graphics card to receive adequate power. Option B is correct because a SATA power to 6-pin PCIe power adapter similarly provides +12V and ground from a SATA power connector, which can also supply the necessary current for the graphics card's PCIe power input.

Answer

4-pin Molex to 3-pin fan adapter

Answer

6-pin PCIe to 8-pin PCIe power adapter

Question 15

A network technician is configuring a small office network. The office has two departments: Sales and Accounting. The technician needs to ensure that devices in Sales cannot communicate with devices in Accounting, but both departments must be able to access the internet. The network uses a single router and one managed switch. Which of the following should the technician configure on the switch?

Accepted Answer

VLANs. VLANs (Virtual Local Area Networks) allow the technician to logically segment the switch into separate broadcast domains. By placing Sales devices in one VLAN and Accounting devices in another, inter-VLAN communication is blocked at Layer 2, while both VLANs can still access the internet through the single router (which performs inter-VLAN routing if configured, but here only internet access is needed, so the router can simply provide default gateway connectivity without routing between VLANs).

Answer

Port mirroring

Answer

Link aggregation

Answer

Spanning Tree Protocol

Question 16

A network technician is troubleshooting inter-VLAN routing. Clients on VLAN 10 (192.168.10.0/24) cannot communicate with servers on VLAN 20 (192.168.20.0/24). The router has subinterfaces configured for both VLANs and an ACL that permits all traffic between them. The router connects to a Layer 2 switch via a single cable. The switch port connecting to the router is configured as an access port in VLAN 10. Which of the following is the MOST likely cause of the communication failure?

Accepted Answer

The switch port connecting to the router is configured as an access port instead of a trunk. The router connects to the switch via a single cable, and the switch port is configured as an access port in VLAN 10. For inter-VLAN routing using router-on-a-stick, the switch port must be a trunk port that carries multiple VLANs (802.1Q tagged). An access port can only carry untagged traffic for a single VLAN, so frames from VLAN 20 cannot reach the router's subinterface, breaking communication.

Answer

The ACL is blocking traffic between VLAN 10 and VLAN 20

Answer

The router's subinterface for VLAN 20 has an incorrect IP address

Answer

The switch is not configured with VLAN 20

Question 17

A technician is setting up a new Android tablet for a user who wants to connect a Bluetooth keyboard. The keyboard is turned on and in pairing mode. The tablet's Bluetooth is enabled, but the keyboard does not appear in the available devices list. Which of the following should the technician check FIRST?

Accepted Answer

Verify the keyboard's battery is not depleted.. The most common reason a Bluetooth keyboard fails to appear in the device list is that its battery is depleted. Bluetooth keyboards require power to transmit their discovery signals; if the battery is dead, the keyboard cannot broadcast its pairing information, even if it appears to be turned on. The technician should verify the keyboard's battery first because it is the simplest and most likely cause, and it avoids unnecessary troubleshooting steps.

Answer

Ensure the keyboard is within 30 feet (10 meters) of the tablet.

Answer

Check if the tablet's Bluetooth adapter is faulty by testing with another Bluetooth device.

Answer

Restart the tablet to refresh the Bluetooth service.

Question 18

A company runs a web application on a virtual machine in a public cloud. The application experiences predictable spikes in traffic every day between 12:00 PM and 1:00 PM. The company wants to ensure consistent performance during these spikes without permanently upgrading the VM's resources. Which of the following cloud characteristics should the administrator configure?

Accepted Answer

Rapid elasticity. Rapid elasticity is the correct cloud characteristic because it allows the virtual machine's resources (e.g., CPU, RAM) to automatically scale up during the predictable 12:00 PM to 1:00 PM traffic spike and scale back down afterward, ensuring consistent performance without permanently upgrading the VM. This is a core feature of cloud computing defined by NIST SP 800-145, enabling dynamic provisioning and de-provisioning of resources to match demand.

Answer

Measured service

Answer

Resource pooling

Answer

On-demand self-service

Question 19

A network technician changes the company's subnet mask from 255.255.255.0 to 255.255.0.0 to accommodate network growth. All workstations use DHCP except one file server that has a static IP address of 192.168.1.50 with subnet mask 255.255.255.0 and default gateway 192.168.1.1. After the change, a user reports that they cannot access the file server. The user's workstation obtains its IP via DHCP and can access the internet. Which of the following is the most likely cause of the issue?

Accepted Answer

C. The file server still has the old subnet mask 255.255.255.0, which means it considers its local subnet to be 192.168.1.0/24. When the user's workstation receives a new IP from DHCP (likely in a different subnet, e.g., 192.168.2.x), the file server sees that the destination is not in its local subnet and sends traffic to its default gateway (192.168.1.1). However, the file server's own subnet mask prevents it from recognizing the user's IP as local, so it cannot respond directly to ARP requests from the user, breaking communication. The user can access the internet because the DHCP scope and gateway are correctly configured for the new /16 mask, but the static file server is isolated.

Answer

A

Answer

B

Answer

D

Question 20

A user reports that their smartphone's battery drains significantly faster than usual, and the device feels warm to the touch even when idle. The battery is not swollen. Which of the following should the technician do FIRST to diagnose the issue?

Accepted Answer

Check the battery usage per application in the device settings. Option C is correct because the first step in diagnosing rapid battery drain and overheating is to check the battery usage per application in the device settings. This allows the technician to identify if a specific app is consuming excessive CPU resources or keeping the device awake abnormally, which is a common cause of heat generation and battery depletion even when idle. Replacing the battery or performing a factory reset without first checking app-level power consumption is premature and may not address the root cause.

Answer

Replace the battery with a new OEM battery

Answer

Perform a factory reset of the device

Answer

Update the device's operating system to the latest version
