We have a 2016 Server Essentials PDC, and now we'd like to add another DC for failover/backup purposes.

Will it be OK to use 2022 Server Standard for this second DC? (Web searches are returning answers to just about every question except this specific one.)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
