A customer is planning LPARs to run z/VM 6.4 with Linux virtual servers on z14. What is the maximum memory that can be utilized by each z/VM LPAR?

The correct answer is A. 2TB. z/VM 6.4 imposes a maximum real memory limit of 2TB per LPAR, making option A correct - this is a hard architectural ceiling for that specific z/VM release, regardless of the underlying z14 hardware's larger capacity. Option D (512GB) is too low and reflects limits from much…

Explanation

z/VM 6.4 imposes a maximum real memory limit of 2TB per LPAR, making option A correct - this is a hard architectural ceiling for that specific z/VM release, regardless of the underlying z14 hardware's larger capacity. Option D (512GB) is too low and reflects limits from much older z/VM or system configurations, not z/VM 6.4. Options B (4TB) and C (10TB) exceed what z/VM 6.4 supports; larger memory capacities became available in later z/VM releases (z/VM 7.x), which take advantage of newer hardware capabilities. For the exam, anchor this fact with: "z/VM 6.4 tops out at 2TB" - if you see 6.4 specifically called out, the answer is 2TB, not the larger values associated with newer releases.
