A retailer's Business Critical database must remain available if an entire Azure region fails. Which TWO actions provide cross-region recovery capability? (Choose two.)
Choose two.
Show answer and explanation
Answer: B and D
Cross-region recovery requires a copy of the data or the backups outside the primary region. An auto-failover group keeps a continuously replicated secondary in another region and provides listener endpoints that move the service during failover, which gives the fastest recovery. Geo-redundant backup storage places backups in a paired region, so the database can be geo-restored there when the primary region is lost. Recovery is slower than a failover but requires no standing secondary. Zone redundancy protects only within one region, read scale-out serves read queries, and automatic tuning changes query plans or indexes, so none of those addresses a regional outage.
Why the other options are wrong
- A. Zone redundancy places replicas across availability zones inside a single region. It protects against a zone failure but offers no copy that survives the loss of the whole region.
- C. Read scale-out adds a read-only replica to serve reporting queries. That replica sits in the same region as the primary, so it gives no protection when the entire region is unavailable.
- E. Automatic tuning corrects query plan regressions and index issues. It improves performance but does not create a copy of the database or its backups in another region.
