220-1201 Practice Test 28 — 15 Questions

Question 1

A company needs to deploy a virtualized environment where each VM must be isolated from others for security reasons, but all VMs share the same physical network. Which virtual networking configuration should be used?

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

Accepted Answer

Use a virtual switch with port groups assigned to different VLANs. VLANs provide network isolation at Layer 2, allowing VMs on the same physical network to be separated logically. This is a common security practice in virtualized environments.

Answer

Configure each VM with a different MAC address

Answer

Use bridged networking for all VMs

Answer

Assign each VM a static IP address from a different subnet

Question 2

A technician is troubleshooting a hybrid cloud environment where an on-premises application needs to access a cloud-based database. The connection is intermittent and slow. The technician checks the local network and finds no issues. Which of the following is the most likely cause?

Accepted Answer

The internet connection between the sites has high latency or packet loss. In a hybrid cloud, latency and bandwidth issues often stem from the internet connection between the on-premises site and the cloud. Even if the local network is fine, the WAN link may be congested or have high latency. DNS or firewall issues would typically cause complete failures, not intermittent slowness.

Answer

The cloud database is configured with the wrong DNS records

Answer

The on-premises firewall is blocking the database port

Answer

The cloud provider is performing maintenance on the database server

Question 3

A user reports that their cloud-based application is running slowly, and the IT team discovers that the application is hosted in a different geographic region than the user. Which cloud concept is most directly affecting performance?

Accepted Answer

Latency. This scenario tests understanding of latency in a global cloud context. When an application is hosted far from the user, the physical distance increases network latency, causing slow performance. Bandwidth could be a factor but is not directly tied to geographic distance, while elasticity and fault tolerance are unrelated to the location of the host.

Answer

Bandwidth

Answer

Elasticity

Answer

Fault tolerance

Question 4

A customer wants to install a modular power supply in their PC but notes that the included cables have different pin shapes on the PSU end. What should the technician advise?

Accepted Answer

The technician should use only the cables that came with that specific power supply.. Modular PSU cables are keyed to prevent incorrect insertion, but they are not standardized across brands. Using cables from a different PSU can cause shorts and damage components. Always use the cables that came with the specific PSU.

Answer

The cables are interchangeable as long as they fit the connector.

Answer

The technician should verify the pinout diagram and use cables from the same manufacturer.

Answer

The customer should return the PSU and buy a non-modular one.

Question 5

A user reports that their multifunction printer makes a loud grinding noise when printing, and the output has vertical black streaks. The technician has already replaced the toner cartridge. What component is most likely failing?

Accepted Answer

The imaging drum. This question tests advanced troubleshooting of laser printer mechanical issues. The imaging drum is a common wear item that can cause grinding noises and vertical streaks when damaged. The fuser or pickup rollers would produce different symptoms.

Answer

The fuser assembly

Answer

The pickup rollers

Answer

The transfer roller

Question 6

A user complains that when they scan a document to a network folder from the MFP, the scanned file is saved as a blank image. The MFP is configured to scan to a shared folder on a Windows server. What is the most likely cause?

Accepted Answer

The scanner needs to be recalibrated.. A blank scanned image typically indicates the scanner is not capturing data, often due to a calibration or sensor issue. The MFP's scanner calibration can drift over time, leading to all-white scans even though the scanning process appears to run.

Answer

The network folder is full.

Answer

The scan resolution is set too low.

Answer

The network cable is faulty.

Question 7

A company uses a Type 1 hypervisor for production servers. A technician needs to migrate a running VM from one host to another without any downtime. Which feature should be used?

Accepted Answer

Perform a live migration using the hypervisor's built-in feature. Live migration is the hypervisor feature that moves a running VM between hosts with no downtime by transferring memory state and CPU context while the VM continues running. Type 1 hypervisors like VMware ESXi (vMotion), Hyper-V (Live Migration), and KVM (live migration) support this natively. Snapshots, cloning, and OVF export/import all require downtime or produce copies, not live moves.

Answer

Snapshot the VM and restore on the new host

Answer

Use virtual machine cloning

Answer

Export the VM as an OVF and import on the new host

Question 8

A technician is troubleshooting a PC that fails to boot and emits a series of long beeps. The motherboard documentation indicates this is a memory error. Which component on the motherboard is responsible for generating these beep codes?

Accepted Answer

BIOS/UEFI chip. The BIOS/UEFI firmware is responsible for the Power-On Self-Test (POST) and uses the speaker to emit beep codes to indicate hardware errors. The CMOS battery only retains settings, the chipset handles data flow, and the Super I/O manages I/O but not POST beep codes.

Answer

CMOS battery

Answer

Chipset

Answer

Super I/O chip

Question 9

A user reports that their laser printer jams frequently, but only when printing on both sides (duplex). Single-sided printing works fine. The technician has inspected the paper and it is within specifications. What is the most likely cause of this issue?

Accepted Answer

The duplex unit is misaligned or has a mechanical fault.. Duplex jams often occur because the duplex unit (the mechanism that flips the paper) is misaligned or has a broken gear. Single-sided printing bypasses this unit, so it works fine. Other causes like paper path rollers or fuser issues would typically affect both simplex and duplex printing.

Answer

The paper is too thick for duplex printing.

Answer

The fuser roller is worn out.

Answer

The printer driver is set to 'duplex' incorrectly.

Question 10

A technician is called to a warehouse where a newly installed IP camera shows 'No Signal' on the NVR. The camera is connected via a 100-meter Cat6 cable to a PoE switch. The switch port LED is off. What is the most likely cause?

Accepted Answer

The cable length exceeds the maximum specification for Ethernet.. This question tests knowledge of Ethernet cable length limits. Cat6 is rated for 100 meters; at exactly that distance, signal degradation can cause link failure. The PoE switch may not provide enough power over that distance, or the cable may be slightly too long.

Answer

The camera's IP address is conflicting with another device.

Answer

The PoE switch does not support the camera's power requirement.

Answer

The camera is configured for a different VLAN.

Question 11

A user reports that their desktop computer connected to the network via a 10-meter Cat6 cable keeps losing connectivity when they move their chair. The cable runs under the desk and is occasionally stepped on. What is the most likely issue?

Accepted Answer

The cable has been crushed or kinked from being stepped on.. This question tests basic troubleshooting for physical cable damage. The correct answer is that the cable is likely damaged from being stepped on, causing intermittent connectivity.

Answer

The cable is too long for reliable connectivity.

Answer

The cable is not shielded and picking up interference.

Answer

The network switch port is faulty.

Question 12

A technician is troubleshooting a server that uses a hardware RAID controller with a 1 GB cache. The server experiences periodic write performance drops, and the event log shows 'Cache battery low' warnings. What is the most likely impact of this condition?

Accepted Answer

The controller will disable write caching to protect data integrity.. RAID controllers use cache batteries to protect data in write cache during power loss. When the battery is low, the controller may disable write caching to prevent data loss, causing write performance to drop. This tests knowledge of RAID controller cache behavior.

Answer

The controller will switch to read-only mode.

Answer

The controller will increase the stripe size to compensate.

Answer

The controller will automatically rebuild the array.

Question 13

A technician is troubleshooting a display that shows a single vertical line of dead pixels from top to bottom. The monitor is under warranty. Which of the following is the most appropriate resolution?

Accepted Answer

Replace the monitor under warranty. A vertical line of dead pixels indicates a defect in the LCD panel's column driver or bonding, which is a hardware failure. Unlike a few stuck pixels, this cannot be fixed by software or gentle pressure. The correct answer is to replace the monitor under warranty, as this is a manufacturing defect.

Answer

Use a pixel-fixing software to cycle colors rapidly

Answer

Gently massage the affected area with a soft cloth

Answer

Update the graphics card driver

Question 14

A user reports that their MFP is making a loud grinding noise when printing, and the output pages have vertical streaks. The MFP is a laser printer with a separate toner cartridge and imaging drum. What is the most likely cause?

Accepted Answer

The imaging drum is damaged or worn.. Vertical streaks on laser printer output often indicate a damaged or worn imaging drum. The grinding noise suggests a mechanical issue with the drum rotation, which is a common failure point in laser MFPs.

Answer

The toner cartridge is low on toner.

Answer

The fuser unit is failing.

Answer

The paper tray is misaligned.

Question 15
