1z0-485: Oracle Exadata Database Machine 2014 Implementation Essentials Iorm Practice Questions

When using IORM, which statement accurately describes when redo log file writes take place?

• AA. Based on the priority of the user
• BB. Immediately
• CC. Based on the resource group of the user
• DD. Based on the intradatabase resource plan

Consider the following setup: User A1 belongs to resource group High on Database A. User B2 belongs to resource group Low on Database B. User C3 is a user on Database C without any DBRM setup. DBRM setup: Database A: Resource group High gets 80% and Low gets 20%. Database B: Resource group High gets 60% and Low gets 40%. IORM setup: Database A: Share=20, limit=5 Database B: Share=30, limit=10 Database C: 5 shares Total number of shares in the IORM setup = 100 What percent of I/O will each database user theoretically be using when the Exadata storage unit I/O throughout is used 100% and no other databases but A, B, and C are running?

• AA. Al = 36%, B2=18%, and C3=9%
• BB. Al = 33%, B2=33%, and C3=33%
• CC. AI = 10%, B2=5%, and C3=20%
• DD. Al = 8%, B2=12%, and C3=5%
• EE. Al = 5%, B2=10%, and C3=85%
