CompTIA A+ Core 1 (220-1201) display technology objectives emphasize that contrast ratio is strongly influenced by how well a screen can produce true black. OLED (Organic Light-Emitting Diode) panels are known for the highest contrast ratios because each pixel is self-emissive—meaning it generates its own light. When an image requires black, OLED can turn individual pixels completely off, producing near-perfect black levels and extremely high (often “infinite”) contrast in practical terms.

By comparison, LCD panels require a backlight, so black areas still allow some light leakage through the liquid crystal layer, reducing contrast. LED in this context is typically an LED-backlit LCD, not a fundamentally different pixel technology; it improves brightness and efficiency but still relies on backlighting, so contrast is limited by backlight bleed and panel design. QLED is also a type of LCD technology that uses a quantum dot layer to enhance color and brightness, but it still uses a backlight, so it cannot match OLED’s per-pixel shutoff for black levels. Therefore, OLED is the best choice for the highest contrast ratios.

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 .

In the CompTIA A+ Core 1 (220-1201) networking concepts, satellite internet is commonly associated with higher (increased) latency compared with terrestrial options like cable, fiber, or DSL. Latency is the delay between sending data and receiving a response. With satellite, signals must travel from the user’s dish up to a satellite and then back down to a ground station (and return again for responses). That long travel distance adds noticeable delay, which can affect real-time activities such as VoIP, video conferencing, and online gaming. Even though newer low-earth-orbit (LEO) systems can reduce latency compared with older geostationary systems, satellite service is still generally discussed in A+ as having higher latency characteristics to consider.

The other options do not best fit satellite internet. Proximity to urban infrastructure (A) is more relevant to cable/fiber availability. An eSIM requirement (B) relates to cellular/mobile service, not satellite broadband. Line of sight to a nearby tower (C) describes cellular or fixed wireless services that depend on tower connectivity; satellite instead needs a clear view of the sky toward the satellite (not a nearby tower). Therefore, increased latency is the best characteristic to consider.
