Answer:
To save the course object instances in an array, use;
Course[] courses = new Course[7];
courses[0] = new Course("IT 145");
courses[1] = new Course("IT 200");
courses[2] = new Course("IT 201");
courses[3] = new Course("IT 270");
courses[4] = new Course("IT 315");
courses[5] = new Course("IT 328");
courses[6] = new Course("IT 330");
Explanation:
The java statement above assigns an array of size 7 with the course class constructor, then order courses are assigned to the respective indexes of the new array.
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 .
At the: Firewall, the DMZ is configured in the Organization. Within the firewalls, it is accessible. They have been completed with the intention of adding an additional layer of safety to the organization to protect it.
The DMZ safeguards not only the web server but also the remainder of the network. To allow visitors to the network to access the web server, a security breach must be made.
The DMZ lessens the possible risk caused by this gap. A secure network, protected by the FortiGate, that only permits access if it has been specifically authorized is known as a DMZ network (from the term "demilitarized zone").
In this illustration, a private subnet is used by the DMZ network, which permits access to a web server by internal and external users using distinct addresses while blocking access from the web server to the internal network in the case that the web server is compromised.
