Oracle Exadata Database Machine X7 and Database In-Memory — Question 21

Which new key architectural element introduced in WebLogic Server l2c should you take advantage of when designing Disaster Recovery Centers with active - passive mode?

Answer options

• A. MAN Clusters, because they would allow you to synchronously replicate state in low latency networks
• B. WAN Clusters, because they would allow you to asynchronously replicate state in nonlow latency networks.
• C. Transaction Log in the database, because you could avoid synchronizing two replication technologies (database and file)
• D. Data Guard, because it is the most effective way to replicate a state across locations
• E. GoldenGate, because it is the most effective way to replicate a state across locations

Correct answer: E

Explanation

The correct answer is E, GoldenGate, as it is specifically designed for effective state replication across different locations, making it ideal for Disaster Recovery Centers in active-passive mode. Options A and B refer to clustering technologies that are not as effective for this purpose, while C discusses a database feature that does not focus on state replication, and D, while relevant, does not match the specific capabilities of GoldenGate.
