Answer:
a. 118.20.210.254
Explanation:
Here are the few characteristics of Class A:
First bit of the first octet of class A is 0.
This class has 8 bits for network and 24 bits for hosts.
The default sub-net mask for class A IP address is 255.0.0.0
Lets see if the first bit of first octet of 118.20.210.254 address is 0.
118 in binary (8 bits) can be represented as : 1110110
To complete 8 bits add a 0 to the left.
01110110
First bit of the first octet of class A is 0 So this is class A address.
For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address
For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address
For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.
The answer is IPS (Intrusion Prevention Systems)
The Intrusion Prevention Systems and Intrusion Detection Systems (IDS) are two security technologies that secure networks and are very similar in how they work. The IDS detects unauthorized user activities, attacks, and network compromises, and also alerts. The IPS, on the other hand, as mentioned, is very similar to the IDS, except that in addition to detecting and alerting, it can also takes action to prevent breaches.
