Explanation

In Oracle Exadata multirack configurations, Enterprise Manager agents are required on all database servers (to monitor compute nodes) and on a minimum of two storage servers in each rack (to provide redundant, complete cell monitoring coverage across the storage grid). Option E is correct because it captures both requirements together - all DB servers plus at least two storage servers in both racks. Option A is also independently true as a factual statement: at least two storage servers in both racks must have agents deployed.

The distractors fail for these reasons: B is wrong because one DB server is insufficient - all DB nodes require agents. C and F are wrong because they cover only one rack, missing the second. D is wrong because agents on all storage servers are not required - only a minimum of two per rack. G is wrong because one storage server per rack is insufficient; at least two are needed for proper monitoring coverage.

Memory tip: Think "All DBs, Two Cells per rack" - every database server gets an agent, but you only need a minimum of two storage cells per rack (not all of them), since Exadata cell metrics are accessible cluster-wide once a few agents are in place.
