Oracle 1z0-133 問題集

質問 1：
You want to configure WebLogic Server transactions to be recoverable when a nonclustered managed server crashes, even if that crash is caused by an unrecoverable hardware failure. You want to run the managed server on different hardware, and have it recover the transactions that were in-progress at the time of the crash.
You also want to use the default store for transaction logs.
Which statement is true?
A. This scenario is not possible. You must use clustered managed servers to recover transactions from a crashed server.
B. After the crash, obtain a copy of the managed server's default store from the administration server.
Move it to the same relative location on the new hardware before starting the managed server there.
C. This scenario is common, and so the default configuration of the default store works.
D. Before the crash, you need to update the path to the default store for the managed server. The path should be to some shared storage location.
E. This scenario is not possible. You must use the JDBC store to recover transactions from a crashed server.
正解：D

質問 2：
You are responsible for installing and setting up WebLogic Server to support the development, testing, and production of an application. Each phase of the application's life cycle has different scalability, performance, and security requirements. How will you implement this?
A. Create a single domain with three managed servers
B. Create three domains
C. Create a single domain with three clusters
D. Create a single domain with three administration servers
正解：A

質問 3：
Consider an application that comprises both web and EJB components.
What are two benefits of implementing a multitier cluster architecture over a single-tier(basic) cluster architecture? (Chose two.)
A. Each cluster can be scaled independently
B. Future web clusters can share the same EJB tier
C. Dynamic clusters are only supported for the multitier architecture
D. All servers can be managed (started/stopped) together
E. Remote EJB access is blocked
正解：B,D

質問 4：
You need to configure WebLogic Server to satisfy the needs of your new application that will update more than one data set on several databases in the same transaction.
All updates will be committed or rolled back at the end of the transaction.
Which setting should be considered?
A. WebLogic Server supports distributed transactions by default, so no specific settings are required.
B. Enable Use XA Data Source Interface in the transaction properties of each data source.
C. Configure your data sources with the available XA-compliant driver for your DBMS.
D. Enable Two-Phase Commit in each data source.
E. Split the transaction into multiple local transactions.
正解：D

質問 5：
The Administration Server of a domain fails due to a hardware failure. The hardware is beyond repair.
Before the failure you prepared a "backup admin server". You go through your planned recovery process and are successful. The Administration Server is now running on different hardware. The managed servers of the domain automatically reconnect to the admin server.
Select the two statements that are true. (Choose two.)
A. The backup admin server is any one of the running managed servers. You select one of the managed servers, stop it, set its "administration" flag, and restart it as the admin server of the domain.
B. When the admin server failed, you must have shut down and restarted the managed servers, otherwise they could not have reconnected to the failed admin server.
C. The backup admin server must be running at the same DNS name or IP address as the original.
D. At the time of the failure, the backup admin server was running in "Standby" mode on different hardware in the same network.
E. Files of deployed applications are available to the backup admin server from the same relative location as they were to the original admin server.
正解：C,D
