Explanation / Answer

14.

Network servers are used for high processing of data or information. During this processing the servers will dessipate more heat. If this heat is not controlled the components in the system will get damaged or the system may hang. So sufficient cooling has to be provided inside the room.

Seperate heating systems will increases the heat in the room and severe the issue of system heating.

False ceiling helps in avoiding the leakage of cool air but not helps in suppressing the heat.

Shared electric circuit will not help to avoid heat generation.

Hence, adequate cooling is required.

The password is said to be strong password when its length is of atleast 8 characters and have the combination of different elements like upper case letters, lower case letters, symbols, numbers etc. So that the permutation level of guessing the password and to decrypt it will be difficult for hackers. From the given choices G6a#bvP& is a good password because it follows all the above rules.

17.

For an user, to access and to perform a task on the network he must have the authority to do so.

Authentication is used to identify whether the person is a legible person or not. To authenticate the person password is used.

Auditing is for verifying.

Logon is the procedure of accessing the network.

Authorization is having the authority to do something. So, to access and to perform the task on a network one should need the authorization.

18.

The intruders can guess the password even it is disabled and in the time it gets expire. We can foil intruders to prevent password guessing by making the account locked for few minutes or reset by specified authenticated user after minimum guesses like 3 attempts or 4 attempts etc. This is called Account lockout.
