The attack that occurs when a domain pointer that links a domain name to a specific web server is changed by a threat actor is known as "domain hijacking".

This type of attack involves the unauthorized transfer of a domain name registration to another entity, giving the attacker control over the domain and potentially the associated web server. Domain hijacking can occur through a variety of methods, including phishing attacks, social engineering, and exploiting vulnerabilities in domain registrar systems. Once the attacker gains control of the domain, they can redirect traffic to a different website or use the domain for malicious purposes such as distributing malware or phishing scams. To protect against domain hijacking, it is important to use strong authentication methods when accessing domain registrar accounts and to monitor domain registration records for any unauthorized changes. It is also recommended to use a reputable domain registrar and to keep domain registration information up to date. Additionally, implementing security measures such as DNSSEC and two-factor authentication can help prevent domain hijacking attacks.

In Java, all variables declared using a class are (d) reference variables.
A brief explanation of each term:
a. Constants - These are variables declared with the "final" keyword, which makes them unchangeable once assigned a value.
b. Primitive variables - These are basic data types like int, float, char, and boolean, which store simple values directly in memory.
c. Operators - These are symbols like +, -, *, and / used to perform operations on variables.
d. Reference variables - When a variable is declared using a class, it becomes a reference variable. These variables store the memory address of the object they refer to, rather than the object's value directly.

The displayStudent method displays the student number, student surname concatenated with the first name with a space and comma in between (i.e. Meintjes, Maria), followed by the overall average on the screen.

The class definition for the Student class would contain four private data members:

- An int studNum to store the student number.
- A string studFirstName to store the student’s first name.
- A string studSurname to store the student’s surname.
- A one-dimensional array subjectCode of type string that holds the five subjects that the student is registered for.
- A parallel array to the subject code array called finalMark that holds the final mark that the student obtained for the subject stored in the subject code array.
- A double overallAverage that will hold the overall average that the student has obtained for all the subjects that he/she is registered for.

The class would have the following methods:

- A default constructor that sets the data members to appropriate default values for all data members, including the arrays.
- A setStudent method that receives parameters for the student number and name, as well as an array of type string and an array of type double for the subjects code and final mark respectively.
- A determineOverallAve method that calculates and returns the overall average of the student for the five tests he/she is registered for.
- A displayStudent method that displays the student number, student surname concatenated with the first name with a space and comma in between (i.e. Meintjes, Maria), followed by the overall average on the screen.


Here is the class definition for the Student class:

```
class Student {
   private:
       int studNum;
       string studFirstName;
       string studSurname;
       string subjectCode[5];
       double finalMark[5];
       double overallAverage;

   public:
       Student() {
           studNum = 0;
           studFirstName = "";
           studSurname = "";
           for (int i = 0; i < 5; i++) {
               subjectCode[i] = "";
               finalMark[i] = 0;
           }
           overallAverage = 0;
       }

       void setStudent(int num, string firstName, string surname, string code[], double mark[]) {
           studNum = num;
           studFirstName = firstName;
           studSurname = surname;
           for (int i = 0; i < 5; i++) {
               subjectCode[i] = code[i];
               finalMark[i] = mark[i];
           }
           overallAverage = determineOverallAve();
       }

       double determineOverallAve() {
           double sum = 0;
           for (int i = 0; i < 5; i++) {
               sum += finalMark[i];
           }
           return sum / 5;
       }

       void displayStudent() {
           cout << studNum << " " << studSurname << ", " << studFirstName << ": " << overallAverage << endl;
       }
};
```

The default constructor sets all data members to appropriate default values, including the arrays.

The setStudent method receives parameters for the student number and name, as well as an array of type string and an array of type double for the subjects code and final mark respectively. It then assigns these values to the corresponding data members and calculates the overall average using the determineOverallAve method.

The determineOverallAve method calculates and returns the overall average of the student for the five tests he/she is registered for.

Explanation:

The first line prints the question. "grade = input()" stores the answer the user will type in the terminal into the variable 'grade'.

grade.lower():

The third line lowercases the entire string ("FreshMan" would turn to "freshman"). Python is case-sensitive.

Then, test the string to see if it matches freshman, sophomore, junior, or senior. If the input string matches print the statement inside the if block. The last statement is the else. It prints if nothing else matches.

Answer:

When a primary replica fails in a document database, several consequences may occur depending on the specific configuration and failover mechanisms in place:

1. Failover: The document database's replication mechanism typically triggers an automatic failover process. During failover, one of the secondary replicas is promoted to become the new primary replica to maintain the availability of the database. This ensures that read and write operations can still be performed on the database.

2. Data consistency: In the event of a primary replica failure, there may be a brief period of data inconsistency between the failed primary replica and the newly promoted primary replica. This is because the failed replica might not have had a chance to replicate all changes to the secondary replicas before the failure. However, most document databases employ mechanisms to ensure eventual consistency among replicas.

3. Replication catch-up: Once the new primary replica is operational, the secondary replicas will begin the process of catching up with any missed changes. They will synchronize data with the new primary replica to restore consistency across all replicas in the database cluster.

4. Notification and monitoring: The failure of a primary replica is typically logged and triggers notifications to administrators or operators responsible for managing the database. Monitoring systems may also detect the failure and generate alerts to ensure timely investigation and resolution.

Overall, the failure of a primary replica in a document database initiates failover processes to maintain database availability, may introduce temporary data inconsistencies, and triggers replication catch-up mechanisms to restore consistency among replicas.
