Supabase Skills Assessment

Questions: 15 | Attempts: 10 | Last updated: Jul 8, 2026

Sample Question
A developer deploys a Supabase project and creates a 'documents' table. They test the API and notice any anonymous user can read all documents. What is the most likely cause?

Supabase has a bug that exposes all tables to anonymous users

Row Level Security (RLS) has not been enabled on the documents table - without RLS, the anon key can read all rows by default

The Supabase API key needs to be regenerated to apply security policies

The table needs to be moved to a private schema to restrict anonymous access

Redis Skills Assessment

Questions: 15 | Attempts: 10 | Last updated: Jul 8, 2026

Sample Question
A real-time leaderboard for an online game needs to rank 1 million players by score and support instant retrieval of any player's rank and score. Which Redis data structure is the correct choice?

Hash, because it stores field-value pairs efficiently for player data

Sorted Set (ZSET), because it maintains elements ordered by score and supports O(log N) rank retrieval with ZRANK and ZSCORE

List, because it preserves insertion order and supports range queries

String, because scores can be stored as string values and sorted in application code

Oracle DBMS Skills Assessment

Questions: 15 | Attempts: 11 | Last updated: Jul 8, 2026

Sample Question
A reporting query on a 500-million-row Oracle table that filters by transaction_date and aggregates by region runs in 45 minutes. An index on transaction_date already exists. What is the most effective next optimization?

Add more RAM to the database server

Partition the table by transaction_date using range partitioning, so queries targeting a date range scan only the relevant partitions

Rewrite the query using a stored procedure

Create an additional index on the region column

MongoDB Skills Assessment

Questions: 15 | Attempts: 10 | Last updated: Jul 7, 2026

Sample Question
A content platform stores articles, each with an author, tags, and a list of up to 50 comments. Reads always fetch the full article including comments. Writes add new comments one at a time. Which MongoDB modeling approach is correct?

Store comments in a separate collection with a foreign key reference, as in a relational database

Embed comments as a subdocument array within the article document, because the data is always read together and the comment count is bounded

Store each comment as a separate top-level document with an article_id field and use $lookup at query time

Use a separate comments collection and cache the joined result in Redis

GraphQL Skills Assessment

Questions: 14 | Attempts: 13 | Last updated: Jul 7, 2026

Sample Question
A frontend team reports that loading a user's profile page makes 12 separate REST API calls to assemble the data. The backend team is considering migrating to GraphQL. What is the strongest technical argument for the migration?

GraphQL is faster than REST because it uses binary encoding

A single GraphQL query can retrieve all required nested data in one round-trip, eliminating the 12 sequential REST calls and reducing page load latency

GraphQL automatically caches all responses at the CDN level

GraphQL removes the need for authentication on API endpoints

Apache Cassandra Skills Assessment

Sample Question
A global e-commerce platform needs to store 500 million product catalog records with extremely high write throughput and reads by product ID. Multi-region availability is required. Which database choice and reasoning is correct?

PostgreSQL with read replicas, because relational integrity matters for a product catalog

Cassandra with product ID as partition key, because it is optimized for high write throughput, horizontal scaling, and multi-datacenter replication natively

Redis, because it stores data in memory and reads will be sub-millisecond

MongoDB with sharding, because its flexible schema accommodates varying product attributes
