CompTIA Updated 220-1201 Exam Questions and Answers by reece

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 D. Router.

According to the CompTIA A+ Core 1 (220-1201) objectives for Networking, routers are devices that operate at Layer 3 (Network layer) and are primarily used to connect multiple networks, including LANs, WANs, and the Internet. Routers use IP addressing to determine the best path for forwarding packets between networks.

Why the other options are incorrect:

A. Controller: Generally refers to a device that manages a network or hardware component but does not inherently connect different networks.

B. Bridge: Connects two segments of the same network, not different networks, and operates at Layer 2 (Data Link layer).

C. Hub: Connects devices within the same network segment, simply repeating signals, and does not perform routing between networks.

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) networking and troubleshooting, a common cause of “can’t reach internal resources” while docked is that the laptop is still using the wireless interface (or has a higher interface priority for Wi-Fi) instead of the docking station’s wired Ethernet connection. If the Wi-Fi network is a guest/isolated VLAN, uses different routing, or has stricter access controls, the user may be blocked from reaching department file servers even though an Ethernet cable is physically connected to the dock. Disabling Wi-Fi is a fast, low-risk step that forces the system to use the wired NIC path through the docking station, which typically provides the correct corporate network access, DHCP scope, and routing to internal servers.

Restarting the computer might help in some cases, but it’s less targeted and not the “best next step” when the likely issue is interface selection. Replacing the Ethernet cable is appropriate if link lights are off or the wired connection is clearly down, but the scenario highlights that the dock has a hardwired connection—suggesting the physical layer may be fine. Dock firmware updates are not a first-line fix for basic connectivity/access symptoms.
