Water Based fire extinguishers should never be used on Electrical Fire. If you do so, it will probably the last time you use such an extinguisher to put out an electrical fire as you will be electrocuted. Any liquid based agent should be avoided for Electrical
Fire.
CO2 systems are effective because they suppress the oxygen supply required to sustain the fire. Since oxygen is removed, it can be potentially lethal to people and gas masks do not provide protection against CO2. These systems are more appropriate for unattended facilities.
The Montreal Protocol of 1987 states that Halon has been designated an ozone-depleting substance and due to the risk to the environment production was stopped January 1st,
1994. Companies that still have Halon systems have been asked to replace them with nontoxic extinguishers. The name of the agreement is called The Montreal Protocol.
Soda acid is an effective fire suppression method for common combustibles and liquids, but not for electrical fires.
TIP:
Do remember the name of the agreement that was signed in Montreal where countries have agreed to stop production of Halon, it is called: The Montreal Protocol
A student of mine told me that he thinks about me when he wish to remember the classes of fire, that scared me off a bit but his explanations made a lot of sense, here how he is using my first name to remember the classes of fire. My name is CLEMENT but he is using only the CLEM portion:
C = Common Combustible
L = Liquid Fire
E = Electrical Fire
M = Metals that are flammable
HERE IS ANOTHER WAY TO REMEMBER THEM FROM HARRISON:
A - Ash (common combustible)
B - Bubble/Boil (Liquid)
C - Circuit (Electrical)
D - Metal. (Just remember it :)

The correct answer is Emanation Eavesdropping. The Tempest program required shielding and other emanation reducing safeguards to be employed on computers processing classified data. The other answers are types of attacks against computers, but are not the focus of the Tempest program.

Cognitive passwords are fact or opinion-based information used to verify an individual's identity. Passwords that can be used only once are one-time or dynamic passwords. Password generators that use a challenge response scheme refer to token devices.
A passphrase is a sequence of characters that is longer than a password and is transformed into a virtual password.

The following is the correct answer: the item's classification and category set.
A Sensitivity label must contain at least one classification and one category set.
Category set and Compartment set are synonyms, they mean the same thing. The sensitivity label must contain at least one Classification and at least one Category. It is common in some environments for a single item to belong to multiple categories. The list of all the categories to which an item belongs is called a compartment set or category set.
The following answers are incorrect:
The item's classification. Is incorrect because you need a category set as well.
The item's category. Is incorrect because category set and classification would be both be required.
The item's need to know. Is incorrect because there is no such thing. The need to know is indicated by the catergories the object belongs to. This is NOT the best answer.
