Practice Test

Question 1

Which of the following protects your application from region-wide disasters? Select the two most appropriate options.

❌ ✔ ⚪ 🔵 ⬜ 🟦 Data Centers

❌ ✔ ⚪ 🔵 ⬜ 🟦 Availability Zones

❌ ✔ ⚪ 🔵 ⬜ 🟦 Regions

❌ ✔ ⚪ 🔵 ⬜ 🟦 Region Pairs

❌ ✔ ⚪ 🔵 ⬜ 🟦 Geographies

✔ That's correct

❌ That's not correct

👨‍🦱 💬 Both Region Pairs and Geographies are designed to be fault-tolerant and help customers replicate their solutions across regions as such allowing them to create highly available applications capable of withstanding region-wide failures.

Question 3

Availability zones are…

❌ ✔ ⚪ 🔵 ⬜ 🟦 Separate data centers with shared IT infrastructure

❌ ✔ ⚪ 🔵 ⬜ 🟦 Physically separate facilities with independent cooling, power and networking infrastructure

❌ ✔ ⚪ 🔵 ⬜ 🟦 Logical groupings of Azure data centers for billing and compliance purposes

✔ That's correct

❌ That's not correct

👨‍🦱 💬 Availability Zones are designed to help customers protect from data center failures by logically grouping physically separate facilities that have their own independent cooling, power and networking infrastructure, and allowing services to take advantage of this fact.

Question 6

Select 4 sentences that best describe an Azure Region Pair

❌ ✔ ⚪ 🔵 ⬜ 🟦 All Azure regions have a region pair

❌ ✔ ⚪ 🔵 ⬜ 🟦 Each region always has a minimum of one pair assigned

❌ ✔ ⚪ 🔵 ⬜ 🟦 Region pairs are designed for easy migration across the regions

❌ ✔ ⚪ 🔵 ⬜ 🟦 Updates across region pairs are synchronized to ensure that they are not updated at the same time

❌ ✔ ⚪ 🔵 ⬜ 🟦 Users can chose which region their region will be paired to

❌ ✔ ⚪ 🔵 ⬜ 🟦 Each region always has exactly one pair assigned

❌ ✔ ⚪ 🔵 ⬜ 🟦 Deploying in region pairs allows customers to maintain data residency

✔ That's correct

❌ That's not correct

👨‍🦱 💬 It is a requirement that all Azure regions have a region pair but regions always have exactly one pair assigned. Microsoft ensures that updates across region pairs are synchronized to ensure that they are not updated at the same time. Region pairs are always within the same geography so customers can maintain their data residency.
