A - Correct Global Variables: Setting a regular global variable using set ::varname value is one of those operations that automatically demotes a virtual server from CMP. This is because CMP relies on consistent state across cores, and modifying global variables can introduce inconsistencies. Static Global Variables: In contrast, setting a static global variable using set static::varname value doesn't demote the virtual server. Static global variables are shared across all cores without impacting CMP, as their values remain consistent.
