Answer:
a. 255.255.255.0 (class C)
b. 255.255.255.224
Explanation:
Here, we want to give the implied subnet mask of the given classful IPV4 address
We proceed as follows;
Given IPv4 address: 200.200.200.200
Classes
Class A : 0.0.0.0 to 127.255.255.255
Class B: 128.0.0.0 to 191.255.255.255
Class C: 192.0.0.0 to 223.255.255.255
Class D: 224.0.0.0 to 239.255.255.255
so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0
In CIDR(Classless Inter Domain Routing)
subnet /27 bits means 27 1s and 5 0s. so subnet
i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .
Answer:c)A digital document that is used to verify the owner's identity
Explanation: Certificate is termed as the digital document that helps in exchanging information or data with protection over the internet.It is used for the maintenance of authentication of user .They are provided with he username and password for the security which can be accessed by the authorized party only.
It verifies the the message sent is by the authorized user and the receiver the decrypts the message.Other options are incorrect because it does not encrypts the data rather has encrypted password and does not certify or change the key's strength .Thus, the correct option is option(c).
