What is a key difference between POP3 and IMAP for retrieving email?

POP3 supports folders on the server, while IMAP does not.

IMAP uses port 110, while POP3 uses port 143.

IMAP allows managing emails on the server, while POP3 typically downloads and removes them.

POP3 keeps emails on the server, while IMAP downloads and deletes them from the server.

A network analyst is troubleshooting a switch that is not forwarding frames between two hosts on the same VLAN. The analyst checks the MAC address table on the switch and sees that the destination MAC address is not present. Which action will the switch take when it receives a frame destined for an unknown MAC address?

Send an ARP request to resolve the destination MAC address before forwarding the frame.

Drop the frame and send an ICMP destination unreachable message to the source.

Forward the frame only to the default gateway to let the router handle the delivery.

Flood the frame out of all ports in the VLAN except the port on which it was received.

Which of the following is a security service provided by TLS/SSL?

Confidentiality through encryption

Integrity through checksums in the IP header

Availability through load balancing

Non-repudiation through digital signatures
