Which statements about a GDS are TRUE?

A GDS, or Global Distribution System, serves as a comprehensive tool for travel agents and hotel operators, enabling them to access various travel services and inventory. The statement regarding requests being entered and corporate rates being available is accurate because GDS systems facilitate real-time booking capabilities and provide agents access to negotiated rates, including corporate or promotional pricing based on agreements with certain companies. This functionality reflects the collaborative nature of GDSs, which integrate inventory from hotels, airlines, and other service providers to accommodate a wide range of booking needs, including corporate travel.

The other statements do not accurately depict the full capabilities of a GDS. For instance, a GDS showcases diverse options beyond basic room types, allowing users to view various accommodations, amenities, and configurations. It is not limited to international bookings; GDSs are used for both domestic and international travel arrangements, catering to a global clientele. Additionally, while GDSs can display promotional rates, they do not exclusively offer them, as they also include standard rates, corporate rates, and other pricing strategies used by hotels and service providers. Thus, option A accurately captures essential attributes of a GDS.
