A financial services firm runs its storage in an Azure region that supports availability zones. Regulators require that data remains available for both reads and writes even if one availability zone fails, but all copies must stay within the primary region. Which redundancy option should the firm use?
Reveal answer
Correct answer: Zone-redundant storage (ZRS), which replicates data synchronously across three availability zones in the primary region

In neurobiology, glial cells wrap axons in myelin sheaths to accelerate neural impulses. On Noos, as your explanations earn accelerations and enter the Wiki Synthesis, the Noos Sphere wraps your Identicon with Keplerian orbits and two quantum nodes on its shoulders.
