Which port is used by Redis data store?

• A. 6379 TCP
• B. 27017 TCP
• C. 1883 TCP
• D. 1433 TCP

Answer: (A)

Redis listens for client connections over TCP, and by default it uses port 6379. This default is set in Redis’ configuration (the port directive in redis.conf), so unless you change it, clients connect to 6379 on the Redis host. The other ports shown are well-known defaults for other services—27017 is commonly MongoDB, 1883 is the MQTT protocol port, and 1433 is the default port for Microsoft SQL Server—so recognizing them helps you match ports to the services they're typically used for. Thus, the standard port for Redis is 6379 TCP.
