220-1102 Practice Test 30 — 15 Questions

Question 1

During a forensic investigation, a technician needs to recover files that a user deleted from their Mac's internal SSD several days ago. The Trash has been emptied. Which macOS feature or tool should be attempted first to recover these files?

Accepted Answer

Restore from a Time Machine backup. Time Machine is the built-in macOS backup feature that automatically creates incremental backups of the system. If a Time Machine backup was made before the files were deleted, the user can browse the backup timeline and restore the deleted files directly, even after the Trash has been emptied. This is the simplest and most reliable first step because it does not require specialized tools or risk overwriting data.

Answer

Use the Terminal command 'fs_usage' to locate the deleted files

Answer

Run Disk Utility First Aid on the SSD

Answer

Use a third-party file recovery tool immediately

Question 2

A system administrator needs to find all files in /var/log that have been modified in the last 24 hours to check for recent activity. Which command accomplishes this?

Accepted Answer

find /var/log -mtime -1. The correct answer is A because the `find` command with `-mtime -1` searches for files whose content (modification time) was changed within the last 24 hours. This is exactly what the administrator needs to check for recent activity in /var/log.

Answer

find /var/log -atime -1

Answer

find /var/log -ctime -1

Answer

find /var/log -mmin -1440

Question 3

A technician needs to search for any file in /etc that contains the string 'Password' (case-insensitive). Which command should be used?

Accepted Answer

grep -ri 'Password' /etc. Option B is correct because the `grep -ri` command performs a recursive (`-r`) case-insensitive (`-i`) search for the string 'Password' across all files under the `/etc` directory. This matches the requirement exactly: case-insensitive search for any file containing the string.

Answer

grep -r 'Password' /etc

Answer

find /etc -name '*Password*'

Answer

locate Password | grep /etc

Question 4

A company's IT policy requires that all wireless traffic be encrypted using the strongest available protocol. A technician is configuring a new access point that supports WPA3-SAE, WPA2-PSK with AES, and WPA2-PSK with TKIP. Which configuration meets the policy?

Accepted Answer

WPA3-SAE.. WPA3-SAE (Simultaneous Authentication of Equals) is the strongest available wireless encryption protocol among the options, as it replaces the pre-shared key (PSK) model with a more secure handshake that provides forward secrecy and is resistant to offline dictionary attacks. The IT policy requires the strongest available protocol, and WPA3-SAE is superior to both WPA2-PSK variants, making option C the correct choice.

Answer

WPA2-PSK with TKIP.

Answer

WPA2-PSK with AES.

Answer

A mixed mode of WPA2 and WPA3.

Question 5

A technician is configuring a cloud-based backup solution for a company's critical data. The company wants to ensure that if the primary cloud provider experiences an outage, the data remains accessible from another provider. Which concept should the technician implement?

Accepted Answer

Cloud federation. Cloud federation enables the interconnection of multiple cloud providers' environments, allowing data and resources to be shared across them. By implementing cloud federation, the technician can replicate critical data to a secondary provider, ensuring that if the primary provider experiences an outage, the data remains accessible from the federated provider. This directly addresses the requirement for cross-provider data accessibility during a provider outage.

Answer

High availability

Answer

Load balancing

Answer

Disaster recovery plan

Question 6

A company uses a private cloud for its development environment. A developer complains that they cannot deploy a new application because the cloud management portal shows a 'resource quota exceeded' error. The technician checks the cluster and finds that CPU and memory usage are below 50%. What is the most likely cause of the error?

Accepted Answer

The developer's resource allocation quota has been reached. The error 'resource quota exceeded' in a cloud management portal is a quota-based restriction, not a physical capacity issue. Since CPU and memory usage are below 50%, the cluster has available resources, but the developer's individual or project-level allocation quota has been reached. This is a common multi-tenant cloud control mechanism to prevent any single user from consuming all resources.

Answer

The hypervisor is in maintenance mode

Answer

The storage pool is full

Answer

The virtual switch is not configured for the developer's VLAN

Question 7

A user's iOS device is running out of storage, and they want to offload unused apps without deleting documents and data. Which iOS feature should be recommended, and where is it configured?

Accepted Answer

Use 'Offload Unused Apps' in Settings > General > iPhone Storage. The 'Offload Unused Apps' feature automatically removes app binaries when storage is low, but preserves the app's documents and data. This is configured in Settings > General > iPhone Storage, where users can also manually offload individual apps. It directly addresses the user's requirement to free up space without losing personal data.

Answer

Enable 'Optimize iPhone Storage' in Photos settings

Answer

Manually delete apps from the Home Screen

Answer

Configure iCloud Storage to offload app data

Question 8

A company's cloud-based CRM application is experiencing intermittent outages. The IT team suspects a distributed denial-of-service (DDoS) attack. Which cloud characteristic is most directly impacted by such an attack?

Accepted Answer

Availability. A DDoS attack floods the CRM application with malicious traffic, overwhelming its resources and causing service disruption. This directly impacts the cloud characteristic of availability, which ensures that services remain accessible to authorized users when needed. In cloud computing, availability is often measured by uptime percentages and is critical for business continuity.

Answer

On-demand self-service

Answer

Broad network access

Answer

Resource pooling

Question 9

A small business wants to migrate its on-premises file server to the cloud to reduce hardware maintenance costs. They need low-latency access for local employees and want to avoid egress fees for large data transfers. Which cloud deployment model best meets these requirements?

Accepted Answer

Hybrid cloud. The hybrid cloud model allows the business to keep sensitive or frequently accessed data on-premises (or in a local edge location) for low-latency access, while leveraging the public cloud for scalability and backup. By using a hybrid architecture, egress fees for large data transfers are avoided because bulk data can be processed locally and only metadata or less critical data is sent to the cloud. This directly addresses the need to reduce hardware maintenance costs while maintaining performance and controlling data transfer costs.

Answer

Public cloud

Answer

Private cloud

Answer

Community cloud

Question 10

A user's iPhone is running iOS 16 and they cannot update to the latest iOS 17 because the 'Software Update' section in Settings shows 'Unable to Check for Update'. The device is connected to Wi-Fi and has sufficient storage. Which advanced troubleshooting step should you take to resolve this update issue?

Accepted Answer

Use a computer with Finder (macOS) or iTunes (Windows) to download and install the update.. Option C is correct because when an iPhone displays 'Unable to Check for Update' despite having Wi-Fi and storage, the issue often lies with the device's inability to contact Apple's update servers directly due to network restrictions or corrupted cached update data. Using a computer with Finder (macOS) or iTunes (Windows) bypasses the iPhone's over-the-air (OTA) update mechanism by downloading the full IPSW firmware directly from Apple's servers and installing it via USB, which is a standard advanced troubleshooting step for OTA update failures.

Answer

Reset All Settings from General > Reset.

Answer

Restore the iPhone using an iCloud backup.

Answer

Disable iCloud Private Relay in iCloud settings.

Question 11

A user reports that their virtual machine running on a Type 2 hypervisor is extremely slow, especially during disk operations. The host machine has 16 GB of RAM and an SSD, but the VM is configured with 2 GB of RAM and a 100 GB dynamically expanding virtual hard disk. What is the most likely cause of the performance issue?

Accepted Answer

The virtual hard disk type is dynamically expanding.. A dynamically expanding virtual hard disk grows in size as data is written, but it does not pre-allocate the full 100 GB. This causes significant overhead because every write operation requires the hypervisor to update the disk's metadata and expand the underlying file, leading to poor I/O performance, especially on a Type 2 hypervisor where the host OS manages the file system. The SSD helps, but the dynamic expansion still introduces latency that a fixed-size VHD would avoid.

Answer

The VM has insufficient RAM allocated.

Answer

The host is running out of physical memory.

Answer

The VM is using an older version of the virtualization software.

Question 12

A technician is tasked with deploying a new virtual machine for a client who needs to run a legacy application that requires a specific configuration. The client wants the VM to be isolated from the host operating system but still needs to access physical USB devices connected to the host. Which type of virtualization technology should the technician use?

Accepted Answer

Type 2 hypervisor. A Type 2 hypervisor runs on top of a host operating system and provides the necessary isolation for the VM while allowing the host OS to manage physical hardware, including USB devices. This setup enables the legacy application to run in a VM with its specific configuration, and the hypervisor can pass through USB devices from the host to the VM via USB passthrough or redirection, meeting the client's requirement for both isolation and USB access.

Answer

Type 1 hypervisor

Answer

Container-based virtualization

Answer

Desktop virtualization (VDI)

Question 13

A company is moving its on-premises email server to a cloud-based service. The IT manager is concerned about data security and wants to ensure that the email data is encrypted both at rest and in transit. Which cloud service model is the company most likely using?

Accepted Answer

Software as a Service (SaaS). The company is moving its on-premises email server to a cloud-based service, which means they are using a complete email application delivered over the internet. Software as a Service (SaaS) provides ready-to-use applications like email (e.g., Microsoft 365, Google Workspace) where the provider manages the infrastructure, platform, and application, including encryption at rest (e.g., AES-256) and in transit (e.g., TLS 1.2/1.3). This aligns with the IT manager's concern about data security without the company needing to manage underlying servers or platforms.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 14

A company uses a cloud-based file storage service. An employee reports that when they try to upload a large video file, the upload fails after several minutes of progress. The employee's internet connection is stable and other uploads of smaller files work fine. What is the most likely cause of this issue?

Accepted Answer

The file exceeds the maximum upload size allowed by the service.. The most likely cause is that the file exceeds the maximum upload size allowed by the cloud service. Cloud storage providers enforce file size limits to manage bandwidth and storage resources, and a large video file would be rejected after the upload begins if it surpasses this threshold. The fact that smaller uploads succeed and the connection is stable points directly to a file size restriction rather than a network or account issue.

Answer

The employee's computer has insufficient RAM.

Answer

The cloud service's server is temporarily overloaded.

Answer

The employee's account has been suspended.

Question 15

A user reports that their virtual machine running on a Type 2 hypervisor is extremely slow. The host machine has 16 GB of RAM, and the VM is configured with 8 GB. The host's task manager shows 90% memory usage. What should the technician do to improve the VM's performance?

Accepted Answer

Reduce the amount of RAM allocated to the VM to 4 GB.. The host is experiencing 90% memory pressure, meaning the host OS is starved of RAM. A Type 2 hypervisor (like VMware Workstation or VirtualBox) relies on the host OS to manage memory; if the host is paging heavily, the VM will also suffer. Reducing the VM’s allocated RAM from 8 GB to 4 GB frees memory for the host, reducing swapping and improving overall VM performance.

Answer

Increase the number of virtual CPUs assigned to the VM.

Answer

Change the virtual disk from thin to thick provisioning.

Answer

Enable hyper-threading on the host CPU.
