Acompany has made the decision to host their own email and basic web services. the administrator needs to set up the external firewall to limit what protocols should be allowed to get to the public part of the company's network. which ports should the administrator open? (choose three.)

Port 25

Port 53

Port 80

Explanation:

Port 25 is to be used for relaying messages between MTAs (Mail Transfer Agents) or from MSAs (Mail Submission Agents) to MTAs.

Port 53 is used by the Domain Name System (DNS), a service that turns human readable names like AuditMyPc.com into IP addresses that the computer understands. Because port 53 is usually open, malicious programs may attempt to communicate on it.

On a Web server or Hypertext Transfer Protocol daemon, port 80 is the port that the server "listens to" or expects to receive from a Web client, assuming that the default was taken when the server was configured or set up. By default, the port number for a Web server is 80.

some have built technology like spoofed call blockers into their networks, so there's nothing you would even have to install.

this happens because the number is known for scamming, they don't want it to me known as "scam likely." perhaps it's just a telemarketer. maybe it's an identity thief. it might even be a scam artist.  

either way, "scam likely" is probably not an old friend whose number you forgot that you saved. it's your wireless carrier's way of letting you know: answer at your own risk.

explanation:

to combat the seemingly rising epidemic of spam callers in the u.s., the nation's four major wireless carriers have been trying out new methods to reduce the number of unsolicited calls americans receive each day.

some have built technology like spoofed call blockers into their networks, so there's nothing you would even have to install.

hope this . mark me brainliest.

this would start to sound a little like mortal combat
