 CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache',
        'LOCATION': '127.0.0.1:11211',
    }
}
AFile-based cache storing data in /var/tmp
BLocal memory cache inside the Django process
CDatabase cache storing data in a DB table
DMemcached cache using PyMemcache client on localhost
Step-by-Step Solution
Solution:
  1. Step 1: Read the BACKEND value

    The backend is set to django.core.cache.backends.memcached.PyMemcacheCache, which uses Memcached with the PyMemcache client.
  2. Step 2: Check the LOCATION

    The location is 127.0.0.1:11211, the default Memcached server address on localhost.
  3. Final Answer:

    Memcached cache using PyMemcache client on localhost -> Option D
  4. Quick Check:

    Memcached backend = PyMemcache + localhost [OK]
Quick Trick: Memcached backend with PyMemcache uses localhost:11211 [OK]
Common Mistakes:
MISTAKES
