单选题 Which new key architectural element introduced in WebLogic Server l2c should you take advantage of when designing Disaster Recovery Centers with active - passive mode?()
MAN Clusters, because they would allow you to synchronously replicate state in low latency networks
WAN Clusters, because they would allow you to asynchronously replicate state in nonlow latency networks.
Transaction Log in the database, because you could avoid synchronizing two replication technologies (database and file)
Data Guard, because it is the most effective way to replicate a state across locations
GoldenGate, because it is the most effective way to replicate a state across locations
多选题 Identify the three processes that customers can choose for patching WebLogic Server.()

Use Enterprise Manager to download patches from My Oracle Support and apply patches to WebLogic.
Download patches from My Oracle Support and manually modify the classpath of the application server (though it is not recommended).
Download patches from My Oracle Support and apply them using the WebLogic Admin Console.
Use the Admin Console to connect to My Oracle Support and download patches and then target them to the domain.

多选题 Which four steps are involved to use Active Cache Dependency Injection in a WebLogic Java EE application?()
Deploy Active Cache shared library
Declare dependency on the shared library
Declare all dependency injection entries

单选题 What is the architectural benefit of keeping WebLogic Server transaction log in the database?()
Oracle does not allow replicating files between data centers, so keeping transaction log in database allows for replication.
Many transactions in WebLogic are database centric, so keeping log in database makes Two Phase Commit protocol possible.
It obviates the need to keep in sync two replication technologies (file and database) between data centers. The single replication technology is used for frequently changing data.
Transaction log in a file system is extremely slow so it cannot be efficiently replicated.

Configure a Work Manager for the MDB with a Minimum Thread Constraint.
Configure a Work Manager for the MDB with a Maximum Thread Constraint and a Capacity Constraint.
Configure a Work Manager for the MDB with a Minimum Thread Constraint and a Capacity Constraint.

人类有两套影响学习的记忆系统:陈述性记忆和程序记忆。陈述性记忆是对事实或者词汇之类基本认识的记忆。而程序记忆,就是一个人“不劳而获”的记忆。程序记忆是人养成习惯和习得技巧的方式,比如骑自行车。在很多时候,这种学习是无意识的。人们用早期发育的程序记忆系统来学习复杂的东西,比如语法规则。帮助人们学习词汇的陈述性记忆系统,则需要更多时问完成发育。儿童拥有程序记忆系统,并且不受陈述性记忆系统的干扰。由此可以推出()。
