There are 1,000 concurrent users of the ASE server. The sp_sysmon report shoes the spinlock contention rate averages 70-80% for the default data cache.

Which steps can be taken to correct this performance problem?

A. Add a 16KB buffer pool to the server.
B. Increase the size of the tempdb database.
C. Add two engines to the ASE server.
D. Add named caches to and bind the appropriate objects to the named caches.
E. Add more locks to the server.

Answer: D

Question 5.
What is the purpose of dsync flag?

A. to synchronize primary and mirroed devices.
B. to synchronize primary and secondary databases.
C. to control whether writes to operating system files are buffered or not.
D. to control Backup Server's access to a dump device.

Answer: C

Question 6.
