1. In any disaster recovery scenario, a direct relationship exists between the frequency at which image copies are taken and sent to the recovery site and which of the following?

The ability to perform a RESTORE SYSTEM

Time spent rebuilding indexes at disaster site

The amount of data that could potentially be lost

The total number of incremental image copies made

2. Which statement is TRUE if the PARAMDEG_DPSI subsystem parameter is set to the default value of 0?

Parallelism for DPSI is disabled

The DB2 optimizer will not consider DPSI for access path selection

DB2 creates multiple child tasks but works on one task at a time when DPSI is used to drive parallelism

DB2 will use the value specified for the PARAMDEG subsystem parameter to control the degree of parallelism when DPSI is used

What would be the most efficient analysis to perform?

Check that the WLM settings are set correctly

Start a system-wide performance trace to identify the workload which is causing the high CPU

Execute a -DISPLAY STATS command to identify the workload which is causing the high CPU

Execute a -DISPLAY TRACED command to check if there are additional traces running or if the global trace is on
