Suggested Answer: D 🗳️
Architecting a database on an All Flash Array (AFA) like EMCs XtremIO is best done by reviewing practices to optimize I/O performance. One consideration is the use of Advanced Format and how it impacts the performance of the database Redo logs. Advanced Format refers to a new physical sector size of 4096 bytes
(4KB) replacing original 512 byte standard.
