Answer:

Under IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (4,096 values provided by the 12-bit VID field minus reserved values at each end of the range, 0 and 4,095).

Answer:

4096 VLANs

Explanation:

A VLAN (virtual LAN) is a group of devices on one or more LAN connected to each other without physical connections. VLANs help reduce collisions.

An 802.1Q Ethernet frame header has VLAN ID of 12 bit VLAN field. Hence the maximum number of possible VLAN ID is 4096 (2¹²).  This means that a switch supporting the 802.1Q protocol can have a maximum of 4096 VLANs

Which is true about POP3 and IMAP for incoming email?
IceJOKER [234]
<h2>Answer:</h2>

Option A: Both POP3 and IMAP  keep email on an email server by default.

is the correct answer.

<h2>Explanation:</h2>

Following points will make the idea of POP3 and IMAP clear:

<h3>POP3:</h3>
  • POP3  is the acronym for Post Office Protocol 3.
  • POP3 is the method of receiving emails in which the emails received on the app can be downloaded on to the computer by having an internet connection.
  • These downloaded emails can be viewed offline whenever needed and managed as well.
  • POP3 makes it possible that the storage space of the default server do not run short as the downloaded emails are deleted from the server.
<h3>IMAP:</h3>
  • IMAP stands for Internet Message Access Protocol.
  • It is the method in which the mails are viewed and managed directly on the internet server instead of downloading them on the computer.
  • IMAP makes sure to manage the mails so carefully and timely so that unimportant mails are deleted to make sure that the storage space does not run short.
<h3>Conclusion:</h3>

So from these points we can make sure that both ways keep emails on email server but POP3 have option to download mails from server while IMAP dont have.
