table 01

Technical Concepts Explained

Four groups of ideas appear in almost every question. Read each one like a small table.

availability

zonalOne zone. Cheapest, but a zone outage takes it down.
regionalCopies across zones in one region for high availability.
multi_regionCopies across regions to survive a regional outage.

recovery

backupA saved copy you can restore.
pitrPoint-in-time recovery: restore to a chosen moment.
rpoHow much data you can afford to lose.
rtoHow long you can afford to be down.

scaling

verticalUse a bigger machine.
read_replicaExtra copies that serve read traffic.
horizontalSpread data across nodes, as Spanner and Bigtable do.
shardingSplit data across separate databases by a key.

consistency

strongEvery read sees the latest write.
eventualReads may briefly lag behind writes.
transactionA group of changes that all succeed or all fail.
indexA structure that speeds up lookups, at some write cost.
table 02

Key Technologies and Tools

The official certification page links to the exam guide and its topic list. The core skill is picking the right database for each requirement.

More relational at the top, more NoSQL at the bottom

Regional, smaller scaleGlobal, massive scale
Cloud SQLManaged MySQL, PostgreSQL, and SQL Server for standard relational apps.
AlloyDBPostgreSQL-compatible and built for demanding relational workloads.
Cloud SpannerRelational with global scale and strong consistency.
FirestoreA document database for mobile and web apps.
BigtableWide-column NoSQL for very high throughput.
MemorystoreAn in-memory cache for very fast reads.

table 07

Common Preparation Mistakes

−Picking one favourite database for every case.
+Match each requirement to the service built for it.
−Treating high availability and disaster recovery as the same thing.
+High availability keeps service up through failures. Disaster recovery restores service after a major loss.
−Skipping migration tools.
+Learn Database Migration Service and Datastream. Migration is about 23% of the exam.
−Ignoring access and security.
+Study IAM, database users, and connectivity options.
−Using old material that leaves out newer topics.
+Check the current exam guide for AlloyDB and generative AI topics.
