Sample 1Z0-076 Questions
Practice with real exam-style questions. Reveal answers to verify your knowledge.
Which three Data Guard monitoring activities may be performed using Enterprise Manager Cloud Control?
Your Data Guard environment has one physical standby database using Real-Time Query. Two sequences have been created by these SQL statements:
Neither sequence has been used since being created.
Session 1 connects to the primary database instance and issues these two SQL statements:
SELECT a.nextval FROM DUAL; SELECT b.nextval FROM DUAL;
Then session 2 connects to the physical standby database instance and issues the same SQL statements. Which output will be seen for session 2?
Then session 2 connects to the physical standby database instance and issues the same SQL statements. Which output will be seen for session 2?
A)
B)
C)
A customer asks you to propose the most appropriate solution for this set of requirements:
We need a disaster recovery solution that enables us to fail over from our production database with zero data loss.
We want to generate reports from the proposed standby database at the same time that it is used for data protection.
Developers may need to test occasionally on a copy of the live database
Which TWO solutions would you recommend?
Which three can be done using Data Guard Broker?
A customer has these requirements for their proposed Data Guard implementation:
1. Zero data loss must still be guaranteed through the loss of any one configuration component.
2. The primary database must be protected against a regional disaster.
3. Performance overheads on the primary should be minimized as much as possible given these requirements.
4. Downtime on the primary database for any reason must be kept to a minimum.
Components referred to in the broker commands are:
A)
B)
C)
