Answer:
a. make multiple fixes.
Explanation:
When we are troubleshooting firewalls we should not make multiple fixes after attempting a fix because it will not be beneficial for the security purpose.
We can repeat the failure after attempting the fix because we can fix it but a person with right mind won't be doing that.
We can test after each attempt that it is working properly.
We can also reverse or undo the solution failures after making a fix.
Answer:
We can periodically take a snapshot of the Domain Name System (DNS) caches in the local Domain Name System (DNS) servers.
Explanation:
We can periodically take a snapshot of the Domain Name System (DNS) caches in the local Domain Name System (DNS) servers. The Web server that appears most frequently in the Domain Name System (DNS) caches is the most popular server. This is because if more users are interested in a Web server, then Domain Name System (DNS) requests for that server are more frequently sent by users. Thus, that Web server will appear in the Domain Name System (DNS) caches more frequently.

C
Explanation:
All the calculation by computer is performed in base 2. Base 2 is also named as binary computation and it is used in all the computer and digital data processing processors.
Some differences between base 2 and base 10 are:
- Base 2 number system contains 0 and 1 whereas base 10 is from 0 to 9.
- Digital systems works on 0 and 1 logic i.e on and off logic. So we use digital system easily in binary domain whereas, decimal system has 0-9 levels and they are hard to be catered in digital domain.
- Base 10 is used in normal calculations for daily use and binary is only confined to digital domain.
