220-1102 Practice Test 48 — 15 Questions

Question 1

A user on a corporate iOS device complains that they cannot install a required business app from the App Store because the device is 'supervised' and shows a message that installation is blocked. What is the most likely reason and solution?

Accepted Answer

The device has a configuration profile that disables App Store installs; update the MDM policy. The 'supervised' status on iOS devices is an MDM-enforced mode that allows granular restrictions. The error message about installation being blocked indicates a configuration profile or MDM policy specifically disables App Store installations. Updating the MDM policy to allow installs is the correct solution, as it directly addresses the restriction without compromising supervision.

Answer

The user needs to sign out of iCloud and sign back in

Answer

Perform a factory reset to remove supervision

Answer

Enable 'Allow Untrusted Shortcuts' in Settings

Question 2

A technician is setting up a virtual machine for a software developer who needs to test an application on multiple operating systems. The host runs Windows 10 Pro with 32 GB of RAM and a quad-core CPU. The developer wants the VM to have direct access to a USB security dongle. Which configuration step is essential to meet this requirement?

Accepted Answer

Enable USB controller passthrough in the VM settings.. Option D is correct because USB passthrough (or USB controller passthrough) allows the virtual machine to directly access and control a physical USB device, such as a security dongle, bypassing the host operating system. This is essential for applications that require direct hardware-level communication with the dongle for licensing or authentication.

Answer

Configure the VM to use dynamic memory.

Answer

Enable virtualization extensions (VT-x/AMD-V) in the host BIOS.

Answer

Install the guest additions or integration services in the VM.

Question 3

A user's iPhone is experiencing random restarts and app crashes after installing a new configuration profile for email. The technician needs to remove the profile but cannot find it in Settings. What should the technician check?

Accepted Answer

Check Settings > General > VPN & Device Management. Configuration profiles are managed under Settings > General > VPN & Device Management. When a profile is installed (e.g., for email), it appears in this section, not in the main Settings list. If the profile is missing from the expected location, the technician should check here first to remove it and resolve the random restarts and app crashes.

Answer

Reset the iPhone's network settings

Answer

Use iTunes to restore the iPhone from a backup

Answer

Disable iCloud Keychain

Question 4

A technician is tasked with deploying a virtual machine for a new employee. The VM will run a Linux distribution and needs to be isolated from the corporate network but still have internet access for updates. Which network configuration should the technician choose for the VM?

Accepted Answer

NAT (Network Address Translation). NAT (Network Address Translation) allows the VM to access the internet through the host's IP address while keeping the VM on a private subnet, effectively isolating it from the corporate network. The host acts as a router, translating the VM's private IP to the host's external IP for outbound traffic, which meets the requirement of internet access for updates without direct corporate network connectivity.

Answer

Bridged networking

Answer

Host-only networking

Answer

Internal networking

Question 5

During a security audit, a technician discovers that a company Android device has an app that can read SMS messages and access contacts without the user's knowledge. The app was sideloaded. What built-in Android security feature could have prevented this?

Accepted Answer

Google Play Protect. Google Play Protect is the correct answer because it is Android's built-in security feature that scans apps for malicious behavior, including those sideloaded from outside the Play Store. It can block or warn about apps that request excessive permissions like reading SMS and accessing contacts without user knowledge. This feature would have prevented the malicious app from being installed or alerted the user before installation.

Answer

Samsung Knox

Answer

Android Device Manager

Answer

Verified Boot

Question 6

A user complains that their virtual machine, which was working fine yesterday, now displays a 'Blue Screen of Death' (BSOD) on startup. The VM is running Windows 10 and is stored on a shared network drive. The host machine is a Windows Server with plenty of resources. What is the most likely cause of this issue?

Accepted Answer

The virtual hard disk file became corrupted due to a network error during the last write operation.. The most likely cause is corruption of the virtual hard disk (VHD/VHDX) file due to a network error during the last write operation. When a VM is stored on a shared network drive, any interruption in the network connection (e.g., transient packet loss, SMB session timeout) during a write can leave the disk file in an inconsistent state, leading to a BSOD on the next boot as Windows encounters critical file system errors.

Answer

The host machine ran out of memory while the VM was running.

Answer

The VM's guest additions need to be updated.

Answer

The hypervisor version is incompatible with the VM configuration.

Question 7

A technician needs to create a virtual machine that will host a legacy application requiring Windows XP. The host runs Windows 11. After creating the VM and installing Windows XP, the technician notices that the mouse cursor is lagging and the screen resolution is stuck at 800x600. What should the technician do to resolve this?

Accepted Answer

Install the guest additions for the VM.. The mouse lag and limited screen resolution (800x600) indicate that the VM lacks proper integration with the host, which is resolved by installing guest additions. Guest additions provide optimized drivers for video, mouse, and other hardware, enabling smooth cursor movement and higher resolutions. This is a standard step after installing any guest OS in a hypervisor like Hyper-V or VirtualBox.

Answer

Increase the amount of RAM allocated to the VM.

Answer

Update the host operating system to the latest version.

Answer

Change the VM's network adapter from NAT to bridged.

Question 8

A technician is troubleshooting a VM that fails to boot with the error 'Operating system not found'. The VM was working yesterday. The technician checks the virtual machine settings and sees that the virtual hard disk is attached to the IDE controller. What should the technician do first?

Accepted Answer

Check the VM's boot order in the BIOS and ensure the virtual hard disk is first. The error 'Operating system not found' indicates that the VM is attempting to boot from a device that does not contain a bootable operating system. Since the VM was working yesterday, the most likely cause is that the boot order in the VM's BIOS has been changed or reset, causing it to try booting from a non-bootable device (e.g., network or CD-ROM) before the virtual hard disk. Checking and correcting the boot order in the BIOS to prioritize the virtual hard disk is the logical first step before making configuration changes.

Answer

Reattach the virtual hard disk to the SCSI controller

Answer

Increase the VM's memory allocation

Answer

Restore the VM from a recent snapshot

Question 9

A user reports that their virtual desktop in a VDI environment is extremely slow during peak hours. The technician checks the host server and sees that memory utilization is at 95% and CPU is at 80%. Which of the following is the most likely cause of the performance issue?

Accepted Answer

The host has insufficient memory for the number of VMs. The host's memory utilization at 95% indicates severe memory overcommitment, which forces the hypervisor to use excessive swapping or ballooning to reclaim memory from VMs. This directly causes extreme slowness for all virtual desktops, especially during peak hours when demand is highest. CPU at 80% is high but not as critical as memory exhaustion, which is the primary bottleneck in VDI environments.

Answer

The virtual switch is misconfigured

Answer

The guest OS needs a driver update

Answer

The virtual hard disks are not thin-provisioned

Question 10

A technician needs to migrate a physical server running a legacy application to a virtual machine on a Type 2 hypervisor for testing. The application requires direct access to a PCIe USB controller card. Which of the following is the best approach to ensure the application continues to function?

Accepted Answer

Enable PCI passthrough for the USB controller card to the VM. Option C is correct because PCI passthrough (also known as VT-d or IOMMU) allows the VM to directly access the physical PCIe USB controller card, providing the legacy application with the exact hardware it requires without emulation or translation overhead. This is essential for applications that need direct hardware access and cannot function through a virtualized or shared USB controller.

Answer

Use a virtual USB controller and map it to the host's USB port

Answer

Install the application directly on the host and share the USB device via network

Answer

Convert the physical server to a VM using P2V and rely on emulated USB

Question 11

A technician is configuring a hybrid cloud environment where an on-premises application needs to securely access a database hosted in a public cloud. The company requires that all traffic between the two environments be encrypted and not traverse the public internet. Which of the following should the technician implement?

Accepted Answer

Use a dedicated private connection such as a direct cloud provider connection. A dedicated private connection (e.g., cloud provider's direct connect service) provides a private, dedicated network link from on-premises to the cloud, bypassing the public internet entirely. This ensures all traffic is encrypted (when combined with IPsec or TLS at the application layer) and does not traverse the public internet, meeting the security and routing requirements.

Answer

Configure a site-to-site VPN over the internet

Answer

Set up a remote desktop gateway

Answer

Deploy a cloud-based load balancer

Question 12

A technician needs to deploy a virtual machine for a client who requires a specific operating system that is not supported by the hypervisor's default settings. The technician has the ISO file for the OS. What should the technician do to install the OS on the VM?

Accepted Answer

Mount the ISO file as a virtual CD/DVD drive and boot from it.. Mounting the ISO file as a virtual CD/DVD drive is the correct method because hypervisors emulate optical drives for VM boot devices. By attaching the ISO to the virtual drive and setting the boot order to CD/DVD first, the VM can boot from the ISO and begin the OS installation process. This approach works regardless of whether the OS is in the hypervisor's default supported list, as the installation media is presented directly to the guest.

Answer

Copy the ISO file directly to the virtual hard disk.

Answer

Use a USB flash drive with the ISO and plug it into the host.

Answer

Change the hypervisor's default settings to support the OS.

Question 13

A small business uses a cloud-based accounting application. Several employees report that they can no longer access the application, and they receive a message stating that the service is temporarily unavailable. The business's internet connection is working, and other cloud services are accessible. What is the most likely cause of this issue?

Accepted Answer

The cloud service provider is experiencing an outage.. The correct answer is B because the scenario describes a service-specific outage: the cloud-based accounting application is inaccessible while other cloud services and the internet connection remain functional. This pattern—one application failing while others work—strongly indicates that the issue is isolated to that particular cloud service provider, not the local network or user accounts. A provider outage would cause the 'temporarily unavailable' message, as the application's servers are unreachable.

Answer

The user's browser cache is corrupted.

Answer

The business's firewall is blocking the accounting application.

Answer

The employees' user accounts have been disabled.

Question 14

A technician is investigating a security incident where a user's virtual machine was compromised. The technician suspects that the VM was infected with malware that spread from the host. Which virtualization security best practice would have prevented this?

Accepted Answer

Keep the hypervisor and host OS updated with security patches.. Option C is correct because keeping the hypervisor and host OS updated with security patches is a fundamental virtualization security best practice that prevents malware from exploiting known vulnerabilities in the hypervisor layer. In this scenario, the malware spread from the host to the VM, indicating a hypervisor-level compromise that patching would have mitigated. Regular patching closes the attack vector that allows host-to-VM infection, such as vulnerabilities in the hypervisor's management interface or device emulation code.

Answer

Enable snapshots for all VMs.

Answer

Use a Type 2 hypervisor for better isolation.

Answer

Assign more virtual CPUs to the VM.

Question 15

During a security audit, you find that a company's server room door is propped open with a trash can to allow airflow. What is the most immediate physical security risk in this scenario?

Accepted Answer

Unauthorized personnel can enter the server room. Option C is correct because the most immediate physical security risk of a propped-open server room door is that it completely bypasses access control mechanisms (e.g., badge readers, PIN pads, biometric scanners). This allows any unauthorized person—whether an employee without clearance, a visitor, or an intruder—to enter the server room undetected, potentially leading to theft, vandalism, or data breaches. Physical security controls are the first line of defense, and an open door nullifies them instantly.

Answer

Increased dust entering the server room

Answer

Fire suppression system may not work

Answer

The door closer will wear out faster
