LAN to WAN domain links the company's infrastructure or local area network to a wide area network or the internet. The WAN domain simply holds publicly the data of an organisation, while remote access domain is meant for a small group of workers in the office or working from home.
Answer: Strong 128-bit encryption.
Explanation: An individual character corresponds to 8 bits . So if there are 16 characters then,
16
8=128 bits keys
This makes the 128 bit key encryption the strongest amongst all other options.It is strongest because it is almost impossible to decode the 128-character key by any method e.g.-brute-force method.
Other options are incorrect because the characters given by the other bits are as follows: 
=32 characters
=64 characters
=128 characters
Thus, the strongest character key is of 128 bits. for cipher.
Answer:
and POP3, followed in later years. POP3 is still the current version of the protocol, though this is often shortened to just POP. While POP4 has been proposed, it's been dormant for a long time.
IMAP, or Internet Message Access Protocol, was designed in 1986. Instead of simply retrieving emails, it was created to allow remote access to emails stored on a remote server. The current version is IMAP4, though most interfaces don't include the number.
The primary difference is that POP downloads emails from the server for permanent local storage, while IMAP leaves them on the server while caching (temporarily storing) emails locally. In this way, IMAP is effectively a form of cloud storage.
