Explanation / Answer
If you post more than 1 question, as per chgg guidelines I have to solve only first question.
Ques 1. Passwords should be changed:
A) at least once a week
C) at least once a month
B) only when you suspect hacking
D) about every 6 months
Answer : (C) at least once a month
If we change every week, then it will be very frequent and if we change about 6 months, it is a very long time and also to change password when you suspect hacking is also wrong as you can't always be sure if your account is being hacked.
Ques 4. When conducting business over the internet, one important way to verify the website is valid and secure is:
A) the web address begins with https
B) the web address end with .org or .com
C) the website only accepts Visa, Mastercard, or Paypal
D) the website has an endorsement verifying it is a legitimate site
Answer : (D)
Options (A) and (B) are not so reliable as any website can begin with http and end with .org or .com.
Also, Visa, Mastercard, or Paypal aren't the only valid and secure payment options.
If a valid endorsement is verifying the site, then we can trust the site.
