Oracle Exam 1Z0-134 Topic 4 Question 99 Discussion

Actual exam question for Oracle's 1Z0-134 exam
Question #: 99
Topic #: 4
[All 1Z0-134 Questions]

Review this scenario of an application running on a storage-disabled, managed Coherence server that uses a Coherence two-tier near cache:

Cache data is already written to the distributed cache.

There is a local near cache configured on the application side (storage-disabled node).

Application requests the data from Coherence twice.

Assuming this is the server's first access of this data from the cache, how many network round trips between Coherence cluster instances take place in total? (Choose the best answer.)

That makes sense, but wouldn't the near cache still need to be accessed?

I disagree, I believe the answer is D) 2 because the data is already in the distributed cache.

This question is like a riddle wrapped in a mystery inside an enigma... but I think I've got it. The data is already in the distributed cache, so the first request would hit the near cache and get it from there. The second request would also find it in the near cache. That's 2 network round trips total, so I'm choosing D.

Yeah, I agree. It's definitely 2 round trips in total.

I think you're right, the data is already in the near cache so it would only be 2 network round trips.

Wait, wait, wait... if the data is already in the distributed cache, and the near cache is configured, shouldn't the application just be able to grab it from the near cache on the first try? That's 1 network round trip, right? I'm going with C, and I'm also going to grab a coffee while I wait for the results.

I'm with you both on this one. Option C seems to be the most logical answer based on the scenario provided. Let's see if we're correct after grabbing that coffee.

Yeah, I also believe it should be 1 network round trip since the data is already in the distributed cache and the near cache is configured. Option C sounds like the correct choice.

I think you're right, the data should be retrieved from the near cache on the first try. So, it should be just 1 network round trip. I agree with you, let's go with option C.

I think the answer is A) 3 because the data is requested twice.

You're right, I see your point now. The answer might indeed be A) 3.

Ah, the classic Coherence two-tier near cache scenario. I'd say 1 round trip, because the data is already in the distributed cache, so the near cache should serve it up without needing to go back to the cluster. C is the way to go, my friend.

But doesn't the application request the data twice, causing additional network round trips?

3 network round trips? Nah, that's too many. Since the data is already in the distributed cache, the application should only need to check the near cache first, and then fetch from the distributed cache if it's not there. That's 2 round trips, so I'm going with D.

Hmm, let me think about this. If the data is already in the distributed cache, and the near cache is on the application side, I'd say 2 network round trips would be needed to fetch the data. The first one to check the near cache, and the second one to get it from the distributed cache if it's not in the near cache. Pretty straightforward, I'd go with D.
