NO.4 A solidDB disk-based database instance has been optimally running for six months and starts to
experience major degradation in performance. Upon executing an overall DB status report using ADMIN
COMMAND "status", it is noted that the value for index writes after last merge is at
20945876. Why would this be a probable cause of the performance degradation?
A. A large value for this counter signifies that the creation of indices, after a large batch insert
process, has been halted leading to excessive memory usage which can cause serious
performance issues.
B. A large value for this counter signifies that a large number of transactions are being
checkpointed which can cause serious performance issues.
C. A large value for this counter signifies that the multi-versioning storage tree is not being flushed
to disk due to a long running transaction which can cause serious performance issues.
D. A large value for this counter signifies that a transaction performing a merge-join is utilizing a
large amount of memory causing potential process paging/swapping leading to serious
performance issues.

NO.5 You have setup solidDB Universal Cache such that you have a table DBA.ORG in the solidDB
front-end, being mirrored to a back-end database. After some time, you notice that the
subscription is Inactive and you try to start Mirroring (Continuous). The subscription state remains
Inactive and the Event Log shows that the structure of table DBA.ORG has changed. What is the
recommended course of action?
A. In solidDB, drop the ORG table and recreate it; then restart the subscription.
B. In the backend database, drop the ORG table and recreate it; then restart the subscription.
C. In solidDB, change the table definition to what it was previously; then restart the subscription.
D. In the Management Console, use the 'Update table definition' option, for the source in the Table
Mappings area; then restart the subscription.
