Using commands like vmstat, sar, Glance, and so on, we can monitor the amount of paging the system is doing. Should we see any paging activity, this is an indication of a serious memory usage. If this pattern of memory use continues, memory usage may become a performance bottleneck. True or False?

A virtual address space ( VAS ) allows many processes to be scheduled simultaneously and all processes to assume that they have unique and total access to the entire range of memory addresses. A VAS also allows the operating system to relocate data and code for any processes to a physical address chosen by the operating system, with no effect on the process itself. True or False?

The rule-of-thumb of "at least twice as much swap space as main memory" is a good starting point for calculating the total swap space requirements for a system. True or False?

The TLB is a cache of the most recently used virtual to physical address mappings. As such, it could be described as a subset of the system-wide Page Directory. True or False?

Every time we add a new dump device to our system, we have to update the LABEL file in the boot area in order for the boot code to be able to locate all dump areas during system initialization. This requires us to use the lvlnboot or vxvmboot commands every time we add an additional dump device as well as updating the /etc/fstab file. True or False?
