FC0-U71 Practice Test 14 — 15 Questions

Question 1

A database analyst is designing a schema for a library system. Each book can have multiple authors, and each author can write multiple books. Which relationship type should be used?

Accepted Answer

Many-to-many. The correct relationship is many-to-many because a book can have multiple authors and an author can write multiple books. In database schema design, this requires a junction table (also known as a linking or associative table) to resolve the many-to-many relationship into two one-to-many relationships, ensuring referential integrity and avoiding data redundancy.

One-to-many

Answer

One-to-one

Answer

RAM

Answer

Hard Drive

Question 15

A hospital uses a legacy application that runs on a Windows 7 workstation. The application stores patient data in a local database. The IT department is migrating all workstations to Windows 10. The legacy application is not compatible with Windows 10. The hospital needs to continue using the application and ensure patient data is accessible from the new workstations. The application requires a dedicated workstation due to licensing. Which solution should the IT department implement?

Accepted Answer

Install a virtual machine with Windows 7 on a Windows 10 workstation and run the application in the VM. Running a virtual machine (VM) with Windows 7 on a Windows 10 workstation allows the legacy application to operate in its native OS environment without hardware compatibility issues. The VM isolates the application and its local database, ensuring patient data remains accessible from the new workstation while satisfying the dedicated workstation licensing requirement by using a single physical host.

Answer

Keep the old Windows 7 workstation on the network for the application and use it as is

Answer

Upgrade the legacy application to a version that supports Windows 10

Answer

Set up a dual-boot configuration on the new workstation to boot into Windows 7 when needed
