The three major problem, which arise there are as follows:
Internet issues, server issues, and server down.
Explanation:
All the issues can be described as follows:
- Internet issues may occur due to censure, cyber warfare, catastrophic events, efforts on the part of police and security utilities. It may also be known as the underwater communications, in which cable breakdowns cause disruptions to large parts.
- A power failure is also the most frequent cause of server failure. If you don't even have a backup generator, storms, natural catastrophes, and statewide power failures may shut your server off.
- It may be overloaded, that can trigger device crashes. Essentially, it's when too many users access the server simultaneously.

Answer:
Explanation:
The following code is written in Java. It creates the function random_marks as requested. It uses three for loops to go concatenating the correct number of apostrophes, quotes, and pairs to the output string before returning it to the user. A test case was added in main and the output can be seen in the attached picture below.
class Brainly {
public static void main(String[] args) {
String output = random_marks(3,2,3);
System.out.println(output);
}
public static String random_marks(int apostrophe, int quotes, int pairs) {
String output = "";
for (int x = 0; x < apostrophe; x++) {
output += '\'';
}
for (int x = 0; x < quotes; x++) {
output += '\"';
}
for (int x = 0; x < pairs; x++) {
output += "\'\"";
}
return output;
}
}
