Answer: (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.

Looking closely at the HTML code sequence, it does seem that the tag element is the endpoint from where the HTML form gets the input, like input boxes, checkboxes, radio buttons, etc. And hence it is correct to say that the tag elements are the last one used in the HTML code sequence. And in the HTML code sequence head title script and styles comes at the top, and hence we mention the script or the Javascript code basically at the last, such that the HTML code or the web page run one time at least.

A component which is most likely to allow both physical and virtual machines to communicate with each other is a: virtual switch.

<h3>What is virtualization?</h3>

Virtualization can be defined as the creation of an abstract layer over computer hardware primarily through the use of a software, in order to enable the operating system (OS), storage device, server, etc., to be used by end users over the Internet.

In Cloud computing, some of the components (features) which is not required for a successful virtualization environment include the following:

  • Virtual machine
  • Host machine
  • Hypervisors

In conclusion, we can infer and logically deduce that a component which is most likely to allow both physical and virtual machines to communicate with each other is a virtual switch because it enables the virtual servers and the desktops to communicate.
