💡 Hint

Common Mistakes

Using incorrect unit abbreviations like 'mbs' or 'mbps'.

Omitting the unit entirely.

Redis accepts both 100mb and 100m for 100 megabytes. Other options are invalid units.

💡 Hint

Common Mistakes

Using incorrect parameter names like 'memorymax' or 'max_mem'.

The correct parameter name to get the maxmemory setting is maxmemory.

💡 Hint

Common Mistakes

Omitting the unit or using incorrect units like 'mbs'.

The correct value must include the unit 'mb' or 'm' for megabytes. Just '256' or '256mbs' is invalid.

Fill both blanks to set maxmemory to 512 megabytes.

Redis

CONFIG SET [1] [2]

💡 Hint

Common Mistakes

Mixing parameter names and values in the wrong order.

Using incorrect units or parameter names.

To set maxmemory, use 'maxmemory' as the parameter and '512mb' as the value. The eviction policy is set separately.

5fill in blank

hard

Fill all three blanks to set maxmemory to 1 gigabyte, set eviction policy to volatile-lru, and verify the maxmemory setting.

Redis

CONFIG SET [1] [2]
CONFIG SET [3] volatile-lru
CONFIG GET maxmemory

Drag options to blanks, or click blank then click option'

Amaxmemory

Cmaxmemory-policy

Dmemory-policy

💡 Hint

Common Mistakes

Using wrong parameter names for eviction policy.

Using incorrect memory units.

First, set 'maxmemory' to '1gb'. Then set 'maxmemory-policy' to 'volatile-lru'. Finally, get the maxmemory value.
