9. A database that has high availability \( \qquad \) . a. gives all users the same access and privileges b. is still available to users even during a failure C c. includes options for sharing over a wide geographic range d. has an increased size capable of handling Big D

High availability databases are designed to remain operational and accessible, even in the event of hardware or software failures. This means that users can continue to query and update data without interruption, ultimately ensuring business continuity and reliability—even during those unexpected server hiccups! When implementing high availability systems, it's essential to use strategies like replication and clustering. However, a common mistake is neglecting proper testing of failover mechanisms; if the backup systems aren’t regularly tested, you might find yourself in a sticky situation when a real failure occurs. So, always remember: practice makes perfect!
