What command would you issue to enable automated backups of control files? （） A: alter database controlfile autobackuon B: alter system controlfile autobackup on  C: configure controlfile autobackup on  D: enable controlfile autobackup

What command would you issue to enable automated backups of control files? （） A: alter database controlfile autobacku on B: alter system controlfile autobackup on C: configure controlfile autobackup on D: enable controlfile autobacku

Which of the following is not a typical maintenance task within a network maintenance model？（） A: Providing technical customer support B: Changing configurations C: Updating software D: Monitoring network performance E: Replacing hardware F: Scheduling backups

When scaling Coherence from one to two cache servers， it will not show the same scalability as two to four. Why？（） A:  Coherence uses a more efficient TCMP algorithm going from two to four cache servers B:  When going from one to two cache servers， object backups are copied across servers so work is doubled，but going from two to four is a fixed amount of work C:  Near cache is enabled with a larger quorum thus performance is improved D:  all of the above

When scaling Coherence from one to two cache servers， it will not show the same scalability as two to four. Why？（） A: A Coherence uses a more efficient TCMP algorithm going from two to four cache servers B: B When going from one to two cache servers， object backups are copied across servers so work is doubled，but going from two to four is a fixed amount of work C: C Near cache is enabled with a larger quorum thus performance is improved D: D all of the above
