for Memcached 11211 and for Redis 6380.
for Memcached 11210 and for Redis 6379.
for Memcached 11211 and for Redis 6379.
Explanations:
The default port for Memcached is 11211, not 11210. While Redis uses port 6380 for TLS connections, the default non-TLS port is 6379.
The default port for Memcached is 11211. Redis does use 6380 for TLS connections, but the standard non-TLS port is 6379, making this option partially incorrect.
Memcached’s default port is 11211, and while Redis uses port 6379 as its default, Memcached’s port is incorrectly stated as 11210.
Memcached uses port 11211, and Redis uses port 6379 as the default for non-TLS connections, making this the correct option.
