問題文
An administrator runs three WebLogic Server clusters in one domain and wants the caches of all three held together. How many Coherence clusters does that call for, and what does the relation between the two kinds of cluster rest on?
選択肢
- One Coherence cluster for each of the three, because a Coherence cluster is a face put on a WebLogic Server cluster and shares both the protocol and the settings of that cluster rather than keeping them apart
- One Coherence cluster is enough, because the caches ride on the same clustering protocol as the WebLogic Server clusters and a domain has only one of those to run at a time
- One Coherence cluster is enough, because several WebLogic Server clusters can each be tied to the one Coherence cluster that a domain has, which runs a protocol of its own
- One Coherence cluster for each of the three, because the protocol of a Coherence cluster is set up apart and cannot carry the members of more than one WebLogic Server cluster
