質問 1：
You are using asynchronous storage replication to protect your critical database server. There are no replication agents installed on the database server. After a disaster, you are unable to bring up the database at the DR site.
What is the cause?
A. An installed agent is required for the database to be quiesce and replicated in crash-
consistent state.
B. The database requires replication from a second storage array.
C. The database requires synchronous storage replication.
D. Two copies of databases are required at the DR site to be able to replay transaction logs.
正解：A
質問 2：
A business critical enterprise resource planning (ERP) system uses a central database at a company's primary data center. The company has built an out-of-region disaster recovery data center and intends to implement a standby ERP system with an eight hour RTO and 30 minute RPO.
Which architectural approach to implement service continuity for the ERP database will meet the RTO and RPO targets?
A. Implement asynchronous replication of the ERP database, application, and middle tiers to ensure the ERP system is back online with less than 30 minutes of data loss within eight hours of an event.
B. Implement synchronous database replication and configure application logic to ensure transactions are identical in both data centers as the recovery objectives do not allow for any inflight data loss.
C. Perform daily full database backups to tape and overnight ship the backup tape media from one data center to the other to ensure the ERP system is back online with less than eight hours of data loss within 30 minutes of an event.
D. Implement asynchronous replication of the ERP database, application, and middle tiers to ensure the ERP system is back online with less than eight hours of data loss within 30 minutes of an event.
正解：A
質問 3：

学生の方でも
ついてこれるぐらいに初歩からじっくり学べるのは良い点
勉強のコツが嬉しい内容でPass4Testブレイクしつつなるほどな、と思ったり。
