The BEST metric for evaluating the effectiveness of a firewall is the:
A.
number of attacks blocked.
B.
number of packets dropped.
C.
average throughput rate.
D.
number of firewall rules.
Explanation:
The number of attacks blocked indicates whether a firewall is performing as intended. The number
of packets dropped does not necessarily indicate the level of effectiveness. The number of firewall
rules and the average throughput rate are not effective measurements.
