A technician receives an invalid certificate error when visiting a website with port 443 enabled. Other computers on the same LA
amm1812

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.

NISA [10]

Answer:

Galen expanded on the Hippocrates' theory of humor by assigning personalities, moods, behaviors, and emotions to the four humors. He believed blood stood for sanguine personality, black bile for a melancholic personality, yellow bile for a choleric personality and phlegm for a phlegmatic personality.

Explanation:

Hippocrates put forward the theory of the four humors. According to the theory, the human body is made up of four substances: black bile, yellow bile, blood, and phlegm. A healthy human body is the product of a balance of among the four humors, while diseases results if there is an imbalance among the four humors.

Galen, a keen admirer of Hippocrates' ideas, further elaborated on this theory and believed that they affected personalities, moods, behaviors, and emotions.

The personalities assigned the four humors are as follows:

People with predominantly black bile are Melancholic (corresponding to the season of autumn dry and cold): They are very sensitive, and enjoy artistic pursuits.

People with predominantly yellow bile are Choleric (corresponding to the season of summer, dry and hot): They possess a passionate temperament, They have a lot of ambition, energy, drive, enormous vitality but are domineering and get angry quickly.

People with predominantly blood are Sanguine (corresponding to the season of spring, wet and hot): These people are confident, joyful, optimistic, expressive, confident, rational and sociable.

People with predominantly phlegm are Phlegmatic (corresponding to the season of winter, wet and cold): They are deep thinkers, fair, calm, very consistent, relaxed, and observant, willing to compromise, and hard workers.
