220-1101 Practice Test 10 — 10 Questions

Question 1

A user reports that their desktop computer will not boot after a power surge. When the power button is pressed, the case power LED lights up, fans spin for about two seconds, and then everything stops. There are no beep codes and no display. The technician has tested the power supply with a multimeter and confirmed that all voltages are within specification. The motherboard shows no signs of physical damage or bulging capacitors. Which component should the technician test or replace NEXT?

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

Accepted Answer

Motherboard. Since the power supply voltages are confirmed good and the motherboard shows no visible damage, the next most likely culprit is the motherboard itself. The symptom of fans spinning briefly and then stopping without beep codes or display indicates a failure in the motherboard's power sequencing or POST logic, often due to a damaged voltage regulator module (VRM) or chipset from the power surge, even without visible bulging capacitors.

Question 2

A technician installs a new VoIP phone that receives power via PoE from a managed switch. The phone powers on but cannot register with the call server. A PC connected to the phone's passthrough port obtains an IP address and accesses the internet normally. Which of the following is the most likely cause of the phone's failure?

Accepted Answer

The switch port has a VLAN mismatch for the voice VLAN. The phone powers on via PoE and the PC behind it works, proving Layer 1 and basic Layer 2 connectivity are fine. The phone cannot register with the call server, which typically requires it to be on the correct voice VLAN. A VLAN mismatch for the voice VLAN means the switch port is configured to tag voice traffic with a different VLAN ID than the phone expects, preventing the phone from communicating with the call server.

Answer

The switch port is configured with a voice VLAN that the phone is not using

Answer

The Ethernet cable between the switch and the phone is faulty

Answer

The phone's MAC address is filtered on the network

Question 3

A technician installs a new network interface card (NIC) into a desktop computer. After installation, the computer boots normally and the NIC is detected in Device Manager without errors. When an Ethernet cable is connected, the link light does not light up on the NIC or the switch port. The cable is known to work with another computer. The technician tries a different port on the same switch, but the link light remains off. Which of the following should the technician do NEXT?

Accepted Answer

Reseat the NIC in the PCIe slot. Since the NIC is detected in Device Manager without errors and the cable works on another computer, the issue is likely a physical connection problem. Reseating the NIC ensures proper contact with the PCIe slot, which can resolve intermittent connectivity or poor electrical contact that prevents the link light from activating.

Answer

Update the NIC driver from the manufacturer's website

Answer

Disable and re-enable the NIC in Device Manager

Answer

Check the NIC's configuration for a disabled port

Question 4

A user reports that their Android smartphone charges very slowly and only when the charging cable is held at a specific angle. The technician inspects the charging port and it appears clean with no visible debris. Which of the following is the BEST first step to resolve this issue?

Accepted Answer

Gently remove any compacted lint from the port using a wooden toothpick or similar non-conductive tool.. The symptom of a smartphone charging only when the cable is held at a specific angle, despite a visually clean port, strongly indicates compacted debris deep inside the port that is not visible during a surface inspection. The best first step is to gently remove any compacted lint using a non-conductive tool like a wooden toothpick, as this is a common, low-risk fix that often resolves the issue without replacing hardware.

Answer

Replace the charging port assembly on the smartphone.

Answer

Use a can of compressed air to blow out the charging port.

Answer

Update the smartphone's operating system to the latest version.

Question 5

A company runs a critical web server on a virtual machine hosted on a Type 1 hypervisor cluster. The cluster consists of two physical hosts connected to a shared storage array. The IT manager requires that if one host fails, the VM should automatically restart on the other host without manual intervention. Which virtualization feature should be configured?

Accepted Answer

High Availability. High Availability (HA) is the correct feature because it automatically restarts a virtual machine on a surviving host in a cluster when the original host fails, without requiring manual intervention. This is achieved by monitoring heartbeat signals between hosts and the shared storage; if a host stops responding, HA triggers the VM restart on another host. The scenario explicitly requires automatic restart on host failure, which is the primary function of HA in a Type 1 hypervisor cluster.

Load Balancing

Question 6

A technician upgrades a desktop computer by installing two new 16GB DDR4 memory modules into the available slots. When the computer is powered on, it emits a series of long beeps and no video is displayed. The technician has verified that the memory is an approved type for the motherboard and that it is installed in the correct slots according to the manual. Which of the following should the technician try NEXT?

Accepted Answer

Test each memory module individually.. The series of long beeps typically indicates a memory error. Since the technician has already verified compatibility and correct slot installation, the next logical step is to isolate the fault by testing each module individually. This will determine if one module is defective or if there is a slot issue, without introducing unnecessary variables like BIOS updates or CPU reseating.

Answer

Update the BIOS to the latest version.

Answer

Reseat the CPU.

Answer

Replace the power supply.

Question 7

A technician is building a new desktop PC and installs a single 16GB DDR4-3200 memory module into slot A1. The system boots and displays 16GB. The technician then adds a second identical 16GB module into slot B1. The system now only shows 16GB total. What is the most likely reason?

Accepted Answer

The second module is not fully seated. The most likely reason is that the second memory module is not fully seated in slot B1. When a module is not properly inserted, the system may not detect it, resulting in the same total memory capacity as before (16GB). This is a common issue during installation, and reseating the module typically resolves it.

Answer

The motherboard does not support dual-channel memory

Answer

The second module is defective

Answer

The modules are installed in the wrong slots for dual-channel

Question 8

A small office has a DHCP server that assigns IP addresses in the range 192.168.1.100 to 192.168.1.200. A file server needs a static IP address of 192.168.1.10. Which method should the technician use to ensure the server always receives that IP address without manually configuring the network adapter on the server?

Accepted Answer

Create a DHCP reservation on the router for the server's MAC address. A DHCP reservation binds a specific IP address to a client's MAC address on the DHCP server (often integrated into the router). This ensures the file server always receives 192.168.1.10 from the DHCP server without requiring manual configuration on the server itself, which is the requirement in the question. The reservation works because the DHCP server checks the MAC address in the DHCP request and always offers the reserved IP.

Answer

Configure the server with a static IP address of 192.168.1.10 in the operating system settings

Answer

Change the DHCP range to 192.168.1.11-200 so that .10 is excluded

Answer

Set up a port forwarding rule for the server

Question 9

A user reports that their workstation can access the internet but cannot access network shares on the local file server. The technician runs ipconfig and sees IP address 192.168.1.100, subnet mask 255.255.255.0, default gateway 192.168.1.1. The technician successfully pings the gateway and a public IP address (8.8.8.8). However, pinging the file server at 192.168.1.50 fails with 'Request timed out'. Other workstations on the same subnet can access the file server. Which of the following is the MOST likely cause?

Accepted Answer

The workstation has a duplicate IP address with another device on the network. The workstation can ping the gateway and a public IP, confirming that its IP configuration, subnet mask, and default gateway are correct and that Layer 3 routing works. However, it cannot ping the file server (192.168.1.50) while other workstations on the same subnet can. This points to a local Layer 2 or Layer 3 conflict specific to this workstation. A duplicate IP address would cause the file server's ARP table to map 192.168.1.100 to the wrong MAC address, so pings from this workstation to the file server go unanswered because the file server sends replies to the other device with the same IP.

Answer

The subnet mask on the workstation is configured incorrectly

Answer

The Windows Firewall is blocking inbound traffic to the file server

Answer

The DNS server is not resolving the file server's hostname

Question 10

A user reports that their VoIP desk phone intermittently drops audio during calls. The phone is connected to a PoE switch via a Cat5e cable that runs through a drop ceiling. The switch shows the port is providing PoE and the cable length is approximately 75 meters. The technician tests the cable with a certifier and it passes. Which of the following should the technician do NEXT to resolve the issue?

Accepted Answer

Check for sources of electromagnetic interference along the cable path. The cable passes certification, ruling out physical layer faults like length or wiring issues. Intermittent audio drops in VoIP over long PoE runs through drop ceilings are often caused by electromagnetic interference (EMI) from nearby electrical cables, fluorescent ballasts, or HVAC equipment. Checking for EMI sources is the logical next step before replacing hardware or upgrading cable.

Answer

Replace the switch port

Answer

Replace the phone

Answer

Upgrade the cable to Cat6
