Question 12

Replication strategies

Answer 12

LRS
ZRS
GRS
RA-GRS
GZRS
RA-GZRS

Question 13

LRS

Answer 13

Single region

Three replicas, one region

Protect against disk, node, rack failures

Write is acknowledged when ALL replicas are committed

Superior to dual-parity RAID

Question 14

ZRS

Answer 14

Single region

Three replicas, three zones, one region

Protects against disk, node, rack, and zone failures

Synchronizes writes to all three zones

Question 15

GRS

Answer 15

Multiple regions

Six replicas, two regions (three per region)

Protects against major regional disasters

Asynchronous copy to secondary

Question 16

RA-GRS

Answer 16

GRS + read access to secondary

Separate secondary endpoint

Recovery point objective (RPO) delay to secondary can be queried

Question 17

GZRS

Answer 17

Multiple regions

Six replicas, 3+1 zones, two regions

Protects against disk, node, rack, zone and region failures

Synchronous writes to all three zones and asynchronous copy to secondary

Question 18

RA-GZRS

Answer 18

Multiple regions

GZRS + read access to secondary

Separate secondary endpoint

RPO delay to secondary can be queries

Question 19

What is Storage’s URL based on

Answer 19

Account name and storage type

blobs.contoso.com has name contosoblobs.blob.core.windows.net

Question 20

How to secure storage accounts

Answer 20

Firewalls and Virtual networks restrict access to the Storage Account from specific subnets on Virtual Networks or public IPs

Subnets and Virtual Networks must exist in the same Azure Region or Region Pair as the Storage Account
