Which set of options can be specified when defining the preferred maintenance schedule of the Exadata Infrastructure for Autonomous Database Dedicated?

When configuring a custom maintenance schedule for an Autonomous Exadata Infrastructure resource, Oracle Cloud Infrastructure (OCI) allows administrators to specify a preferred window for the quarterly infrastructure maintenance. The available scheduling options are designed to provide flexibility within Oracle's quarterly patch cycle. The user can define the schedule by selecting the Month of the Quarter (e.g., the first, second, or third month of the quarter), the Week of the Month (first through fourth), the Day of the Week (e.g., Saturday), and the Start Hour in the UTC time zone. This combination precisely defines the maintenance window.

A. Quarter of the Year, Month of the Quarter, Date of the Month, Start Hour This is incorrect because scheduling is based on the "Day of the Week" for flexibility, not a fixed "Date of the Month," and "Quarter of the Year" is not a user-configurable option.
C. Month of the Year, Week of the Month, Day of the Week, Start Hour This is incorrect. The maintenance cycle is quarterly, so the schedule is defined by the "Month of the Quarter," not a specific "Month of the Year."
D. Week of the Quarter, Day of the Week, Start Hour This is incorrect because it is missing the "Month of the Quarter" parameter and incorrectly uses "Week of the Quarter" instead of "Week of the Month."

1. Oracle Cloud Infrastructure Documentation - Manage Autonomous Exadata Infrastructure: In the section "To configure or change the maintenance schedule for an Autonomous Exadata Infrastructure resource

" the procedure explicitly lists the configurable options: "For Month of the quarter

select the month you prefer."

"For Week of the month

select the week you prefer."

"For Day of the week

select the day you prefer."

and "For Start hour

select the time you prefer." This directly corresponds to the components in the correct answer.

2. Oracle Cloud Infrastructure Documentation - Create an Autonomous Exadata Infrastructure Resource: The documentation for creating the infrastructure resource also describes the maintenance schedule configuration. Under "Show Advanced Options" -> "Maintenance Details"

it states

"You can schedule maintenance by specifying a month of the quarter

a week of the month

a day of the week

and a start hour."
