Oracle 1Z0-1093-25 Exam - Topic 5 Question 16 Discussion

Actual exam question for Oracle's 1Z0-1093-25 exam
Question #: 16
Topic #: 5
[All 1Z0-1093-25 Questions]

What is the MOST effective method to minimize the recovery time objective (RTO) for a BaseDB database in the event of a complete DB system failure, assuming both cost and complexity are important considerations?

Show Suggested Answer Hide Answer
Suggested Answer: C

C . Using Oracle Data Guard with asynchronous replication to a different availability domain within the same region.

Asynchronous Replication:

Minimizes performance impact while ensuring data protection.

Placing standby in the same region reduces latency and cost.

Fast switchover reduces RTO.

Why the other options are less effective:

A . Full backups: Time-consuming for recovery.

B . Synchronous to a remote region: Increases latency and cost.

D . Incremental backups: Slower recovery process.

E . Custom script: Complex and less reliable than Data Guard.

Option E sounds like a job for the IT guy who loves writing custom scripts. I'll stick with the enterprise-grade solution, thanks.

D seems like a good option too, but I'd rather not have to deal with all those incremental backups. B is the clear winner here.

Haha, who needs backups when you have Oracle Data Guard? That's the real disaster recovery solution!

I vaguely remember that asynchronous replication is less effective for RTO than synchronous, but I can't remember the details of why that is.

I think incremental backups with block change tracking could help reduce RTO, but I wonder if they would be enough compared to the Data Guard options.

I feel like relying solely on regular full backups could lead to longer recovery times, but I can't recall the exact numbers we went over in practice questions.

I remember we discussed RTO in class, and I think using Oracle Data Guard with synchronous replication might be the best option, but I'm not entirely sure about the cost implications.

I'm a bit confused by all the options here. I'll need to review the details of each approach and how they impact recovery time, cost, and complexity.

I'm feeling pretty confident about this one. Based on my understanding, using Oracle Data Guard with synchronous replication to a remote region seems like the most effective approach to minimize RTO.

Okay, let me think this through. I'm guessing the key is finding the right balance between backup frequency, data replication, and overall system redundancy.

Hmm, this is a tricky one. I think I'd need to weigh the pros and cons of each approach in terms of cost, complexity, and actual recovery time.
