Answer: Probability/impact risk matrix
Explanation: Probability/impact risk matrix is type of matrix that defines the probability as well as impact that depicts whether the risk is low ,high or moderate.
Impact matrix is sort of tool which helps in conversion of any plan into a action. Probability matrix help in defining the chances in defining the risk.The positioning of the impact value of risk is plotted on the vertical axis and performance value on the horizontal axis.
Thus probability/impact matrix is the correct tool for the problem mentioned in the question.
Answer:
TTL
Explanation:
TTL means time -to- live field is a counter that is designed to keep packets from circulating indefinitely in the network case forwarding tables accidentally create cycles. An IP datagram is typically initialized with a TTL of 60 or 64 and the TTL is decremented by one each time it enters a router. If the TTL reaches zero, the router will discard the packet. It is one of the components of the IP datagram
Answer:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take 
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0
