Question #: 90
Topic #: 8

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.)

Yes, I agree with Eve. Only 1 round trip should happen on first data access. Let's go with C.

Doesn't the first request populate the near cache? So the second request should be local.

It can't be more than 2. The near cache reduces the need for multiple trips.

I'm not sure. I was thinking 2 trips since the application requests the data twice.

I think it's 1 network round trip. The local near cache should hold the data after the first request.

No, it's actually 2 round trips as data is already in the distributed cache.
