Free Practice Questions for CompTIA 220-1201 Exam

The correct answer is A. The internal antenna has been damaged.

According to the CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Networking:

Many laptop Wi-Fi antennas are embedded in the display panel and connected via small cables to the wireless card on the motherboard.

If the display panel is replaced and the Wi-Fi antenna is disconnected, damaged, or improperly routed, the laptop will experience weak or intermittent Wi-Fi connectivity.

Why the other options are incorrect:

B. Airplane mode is enabled: Would completely disable wireless radios; the question specifies difficulty staying connected, not a total lack of connectivity.

C. The inverter is not connected: The inverter powers the backlight of the display, unrelated to wireless connectivity.

D. The wireless drivers have not been updated: While outdated drivers can cause connectivity issues, a sudden problem after a display replacement strongly points to physical antenna damage.

In the CompTIA A+ Core 1 (220-1201) exam objectives, cloud deployment models describe how and where computing resources are hosted and who has access to them. A private cloud is defined as a cloud environment that is dedicated to a single organization and may be hosted on-premises within the company’s own data center or in a dedicated external facility. Since the question states that the directory services server is located on premises, it indicates that the organization is hosting and managing its own infrastructure internally. This aligns directly with the definition of a private cloud deployment model.

Directory services—such as Microsoft Active Directory or LDAP-based services—are commonly deployed internally to manage user authentication, authorization, group policies, and resource access within an organization. When these services run on company-owned hardware inside the organization’s network, the infrastructure remains under the organization’s full administrative control, security policies, and management.

The other options do not match this scenario. A public cloud is hosted by third-party providers and shared among multiple customers ☁. A hybrid cloud combines on-premises infrastructure with public cloud services. A community cloud is shared by multiple organizations with similar requirements. Because the system is hosted internally for a single organization, the correct classification is Private Cloud .

The correct answer is C. Synchronized system clocks.

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Server Services, NTP (Network Time Protocol) is used to synchronize the clocks of computers across a network to a common time source. This is critical for:

Ensuring accurate timestamps for logs and events.

Coordinating scheduled tasks across multiple systems.

Preventing authentication issues in environments that rely on time-based credentials (e.g., Kerberos).

Why the other options are incorrect:

A. Defined network transport protocols: NTP itself is a protocol that uses UDP, but its primary purpose is not defining transport protocols.

B. Enabled print services on the server: NTP does not relate to printing.

D. Defined server options in DHCP: NTP may be referenced by DHCP options, but the act of adding NTP to a server is focused on time synchronization, not DHCP configuration.

In CompTIA A+ Core 1 (220-1201) cloud concepts, the key differentiator between cloud deployment models is where the service is hosted and who owns/uses the underlying infrastructure. If a company’s directory services server (for example, a domain controller providing authentication/authorization and centralized identity management) is located on premises, that points to infrastructure that is owned and operated by the organization for its own internal use. This aligns best with a private cloud model, which is defined as cloud resources dedicated to a single organization and can be implemented on-premises (internally hosted) or in a dedicated off-site environment.

It is not a public cloud because public cloud services are hosted by a third-party provider and shared across multiple customers. It is not hybrid cloud because hybrid requires a mix of on-prem resources and public cloud resources working together (the question only specifies on-prem). It is not community cloud because that involves shared infrastructure among multiple organizations with common needs.

The correct answer is B. Moving to a supported system under a Type 2 hypervisor.

In the CompTIA A+ Core 1 (220-1201) objectives, virtualization is a key concept for maintaining compatibility with legacy systems. A Type 2 hypervisor (hosted hypervisor) runs on top of an existing operating system and allows users to run a virtual machine (VM) with an older OS.

This solution is ideal because:

It allows the legacy application to run in its required OS environment.

It avoids replacing the application (which could cause data loss or compatibility issues).

It is cost-effective, as it uses existing hardware.

It minimizes user disruption, since users can continue using the application within a VM.

Why the other options are incorrect:

A. Setting up a bare-metal hypervisor

A Type 1 (bare-metal) hypervisor is more complex, costly, and disruptive. It typically requires dedicating hardware and is not ideal for a single department use case.

C. Upgrading to an alternative product and importing the data

Although this may be a long-term solution, it involves higher cost, potential data loss, retraining, and disruption.

D. Uploading the database to a private cloud

This does not solve the compatibility issue of the legacy application with the new OS.

Final Answer: B. Moving to a supported system under a Type 2 hypervisor

The correct answer is D. Data is being throttled.

Data throttling refers to the intentional slowing down of internet speeds by a mobile carrier after a user reaches a certain data usage limit or during network congestion. In this scenario, the employee can still successfully upload files, but the speed has decreased compared to before—this is a classic symptom of throttling.

Why the other options are incorrect:

A. Wireless is turned off

If wireless were turned off, the employee would not be able to upload anything at all. The question clearly states that uploads are still successful.

B. 5G is disabled

Disabling 5G could reduce speeds slightly if the device falls back to 4G/LTE, but it would not typically cause a significant or noticeable degradation unless compared under ideal conditions. It is not the most likely cause.

C. Roaming is turned on

Roaming allows connectivity outside the home network. While it may incur additional charges, it does not inherently cause significant speed reduction in most modern networks. It is less likely than throttling.

Exam Tip (Core 1 220-1201):

Slow but working connection → Think throttling or congestion

No connection → Think disabled wireless or network issues

Final Answer: D. Data is being throttled

If a print spooler crashes specifically with one application and no issue occurs on other systems, the most likely root cause is a bug within that specific application. Restarting the spooler and reinstalling drivers resolves system-wide or hardware-related issues not app-specific failures. This indicates the application may be sending malformed print data.

Fiber optic connections provide the highest data transfer rates and symmetrical upload and download speeds. This makes fiber the ideal choice for applications requiring high-speed connectivity, such as video conferencing, large file transfers, and cloud-based workflows.

The default gateway is the network device responsible for routing traffic from a local computer to destinations outside its subnet. When a new firewall is deployed and intended to manage outbound traffic, client devices must be configured to send packets to this firewall. CompTIA A+ identifies the gateway setting as the key parameter that determines where a workstation sends its external-bound traffic.

By updating the gateway address to point to the new firewall’s internal interface, all internet-bound and off-subnet traffic will now pass through the firewall for filtering, inspection, and routing. This ensures correct traffic flow and enforces security policies.

Changing the VPN settings (A) does not affect local traffic routing unless a VPN tunnel is active. Subnet mask adjustments (C) determine the network size but do not control routing. VLAN settings (D) require switch configuration, not workstation changes, and do not dictate default routing behavior.

Thus, modifying the gateway is the correct and necessary step to route all traffic through the newly implemented firewall.

A hypervisor allows multiple operating systems to run simultaneously on a single physical host, making it the ideal solution for providing concurrent access to different test environments. Developers can use virtual machines (VMs) for testing and development.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Compare and contrast cloud computing concepts:

“A hypervisor is software that enables multiple operating systems to run on a single host as virtual machines. This is commonly used in development and testing environments for flexibility and isolation.”
