Anetwork technician configures a firewall’s acl to allow outgoing traffic for several popular services such as email and web browsing. however, after the firewall’s deployment, users are still unable to retrieve their emails. which of the following would best resolve this issue? a. allow the firewall to accept inbound traffic to ports 25, 67, 179, and 3389b. allow the firewall to accept inbound traffic to ports 80, 110, 143, and 443c. set the firewall to operate in transparent moded. allow the firewall to accept inbound traffic to ports 21, 53, 69, and 123

(B) Allow the firewall to accept inbound traffic to ports 80, 110, 143, and 443

Explanation:

Port 80 is used by HTTP, 110 by pop3 to retrieve emails from web servers, 143 by imap for internet messaging and 443 is used for TCP for websites using SSL. So if the firewall is allowed to accept inbound traffic to these ports 80,110,143 and 443 then it would be possible to retrieve emails.

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
