Assume you are a security professional for an educational institution with 10 servers. Researchers on campus push a lot of traffic over the network, which slows performance at times. You also have a limited budget. You are evaluating both stand-alone and embedded firewalls in preparation of a purchase. A stand-alone firewall filters traffic before it reaches your servers, while an embedded firewall would be implemented on each server. Answer the following question(s): Which type of firewall would you choose? Why?

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;
