Viktor S.May 1, 2026The answer is A, and the core reason is that distributing multiple Provisioning Services servers within each site keeps target devices booting locally if the WAN goes down, so you avoid a single point of failure both at the server level and at the network level. If you only had one PVS server per site, or centralized everything, one outage takes down every vDisk stream for that location. Side note: your options A through D are all showing the same truncated text, which means the actual differentiating details got cut off before you pasted this. Find the full option text before exam day, because the real question is testing something specific in those details, not just the opening sentence.
Nina C.May 4, 2026Viktor, the truncated options point is what I would fix first, because I have seen questions on this site where two choices look identical until the last clause, and that last clause is exactly what the question is testing.
Nina C.May 3, 2026Went with B first, then noticed A covers per-site HA correctly.
Toby R.May 4, 2026Same trap got me, B looks right until you catch that A is the only one that handles each site independently instead of treating the whole setup as one HA unit.
Toby R.Apr 11, 2026A is right and this one tripped me up at first because all the options look the same on screen but the actual full scenario diagram is what matters. The key thing the exam is testing is that you want multiple PVS servers per site so that if one goes down, the vDisks can still be streamed locally without crossing the WAN. Cross-site streaming is technically possible but it kills performance and creates a single point of failure on the link, which Citrix explicitly calls out as a bad design in their PVS reference architecture. When I saw this on the exam the question had a specific scenario with two sites and the answer came down to local redundancy being the deciding factor.
Prof. SaraApr 11, 2026Toby nails the local-redundancy reasoning, and the point worth drilling for exam day is that Citrix ties this directly to the Store-to-vDisk locality rule, so if your answer ever involves a single Store shared across sites, that is a red flag regardless of how the WAN question is framed.
Prof. SaraApr 21, 2026D is the play here because Provisioning Services architecture questions on this exam reward you for recognizing the full picture of fault tolerance across all sites, not just local redundancy, and option D captures that complete scope in a way the others do not. Remember the mnemonic HALT, High Availability Looks Total, meaning your design must account for every site in the topology, which is exactly what D does.
Viktor S.Apr 21, 2026Appreciate the effort, Sara, but the question is scoped to local site redundancy for the Provisioning Service, not topology-wide fault tolerance, so A is correct because it addresses the specific failure domain being tested without overreaching into multi-site concerns that the scenario never introduces. HALT is a fine memory hook but it led you to answer a broader question than the one actually on the page.
