Answer:
Option (A) is the right answer.
Explanation:
According to the scenario, the user system is giving the error of invalid certificate while other users on the same network do not report any error, which means that there is some problem in a particular system.
Date and time can also be one of the main cause of this error because wrong date and time creates problem in surfing many websites by giving certificate error.
Hence the most appropriate answer is option (A).
While other option are wrong because of the following reasons:
- UEFI boot mode is mainly used in booting the operating system and has no connection with network.
- Logon time is also wrong because if the problem is with the login server, it can not give certificate error.
- User access control is also not correct because it is used to control the access of the user.

Explanation:
- The subnet mask would be a 32-bit integer which is formed by assigning the host bits to all 0's and the networking bits to so many 1's.
- In this method, the subnetting separates the IP address between host and network addresses.
- The subnet mask covers an IP address with its 32-bit number, thus the term "mask".
Given:
Network IP address
Subnet numbers
Calculating the borrow bits:

a)
Calculating the dotted decimal value for the subnet mask:

b)
The additional bits which will be needed to mask the subnet mask that is = 4.
