Complete the code to set the cache backend to use the local memory cache.

Django

CACHES = {

        'BACKEND': 'django.core.cache.backends.[1].LocMemCache',
        'LOCATION': 'unique-snowflake',
    }
}

💡 Hint

Common Mistakes

Using 'filebased' instead of 'locmem' for local memory cache.

Using 'memcached' without proper setup.

The correct backend for local memory caching in Django is locmem.

Complete the code to set the cache timeout to 300 seconds.

Django

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
        'LOCATION': 'unique-snowflake',
        'TIMEOUT': [1],
    }
}

💡 Hint

Common Mistakes

Setting TIMEOUT to None disables expiration, not 300 seconds.

Using 0 means cache never expires, which is different.

The TIMEOUT setting defines how many seconds the cache will keep data. 300 seconds means 5 minutes.

Fix the error in the cache backend path to use Memcached.

Django

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.[1].MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    }

Common Mistakes

Using 'locmem' backend for Memcached configuration.

Using 'filebased' backend for Memcached.

The correct backend path for Memcached is memcached.

Fill both blanks to configure Redis cache backend with a specific location and timeout.

Django

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.[1].RedisCache',
        'LOCATION': '[2]',
        'TIMEOUT': 500,
    }
}

💡 Hint

Common Mistakes

Using 'memcached' backend with Redis location.

Using 'locmem' backend for Redis.

Redis backend uses 'redis' and the location is usually the Redis server address like '127.0.0.1:6379'.

5fill in blank

hard

Fill all three blanks to create a file-based cache configuration with a directory and no timeout.

Django

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.[1].FileBasedCache',
        'LOCATION': '[2]',
        'TIMEOUT': [3],
    }
}

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

💡 Hint

Common Mistakes

Using 'locmem' backend for file-based cache.

Setting timeout to 0 instead of None for no expiration.

File-based cache backend is 'filebased', location is a directory path, and 'None' means cache never expires.
