Select one:

d. 6

2- Which of the following does not increase the TLB reach?

Select one:

a. Decrease the size working set.

Explanation:

The amount of memory accessible from the TLB.
TLB Reach = (TLB Size) X (Page Size).
The working set of each process is stored in the TLB, Otherwise, there is a high degree of page faults.

Increase the Page Size: This may lead to an increase in fragmentation as not all applications require a large page size
Provide Multiple Page Sizes: This allows applications that require larger page sizes the opportunity to use them without an increase in fragmentation
