Answer:
an instance variable is a variable that is within a class but it is outside of constructors, methods or blocks.
the instance variables for the class bankAccount can be accountNumber, account holder name and balance.
below are the types and names declared to hold the information.
private string accountHolderName;
private int accountNumber;
private double balance;
note:
accountHolderName is a string data type because names are in alphabets.
accountNumber is an integer since they are in numbers.
balance is a double data type because it is a floating point number.
Answer:
Port security and violation mode.
Explanation:
A switch is a layer two device of the OSI model. It is used to transmit frames between nodes within a network. It transfers frames by discovering the destination Mac address and saving it to its address table, and sending the frame to the egest port to the destination.
The port security command is used to specify the Mac addresses that are recognised by a port. There are three types of port security, they are, dynamic, static and sticky Mac addresses that can configured on an interface.
The security violation command is used to decide what happens to a port when it detects an unfamiliar Mac address. The three security violation modes are protect, restrict and shutdown. It is used as an interface command alongside the port security command.
Answer:
D. at the intersection of at least two constraints.
Explanation:
Linear programming is an optimization technique which is fine for the purpose of getting the best solution such as maximizing profit or certain o 4th era quantities. It is fine by modelling real life problems into mathematical models that have linear relationships or constraints such as in the form of objective functions. In linear programming, an objective function defines the formula for quantity optimization and the goal from this is to determine variable values that maximize or minimize the objective function depending on the problem robbery solved.
