b.Constructors never have a return type - not even void
c.Constructors are invoked using the new operator.
Following are the explanation of the constructor and its points:
Box b = new Box(); //It invokes the Box class's default constructors.
Therefore, the final answer is "all the choices are correct".

Answer:
Option B
Explanation:
There is a built in functionality in every OS ( including windows and IOS ) that reboots the system whenever the temperature of Processor reaches to a certain limit. This functionality is to save the hardware of computer so that nothing of it will burn by rebooting the PC which in this specific case will start the fans of computer to run with rather high speed to take out as much heat as possible.
Option A is rejected because Bad network card will result problem in using the network and will not reboot the system.
Option C will make the PC UPS to not to start the computer rather than rebooting it.
Option D will result in no windows start functionality rather than rebooting it.
The three best practices used in the core layer are: a. Use routing with no Layer 2 loops. e. Use Layer 3 switches with fast forwarding. f. Use Layer 3 routing to the core.
a. Using routing with no Layer 2 loops helps prevent broadcast storms and ensures efficient traffic forwarding by relying on Layer 3 routing protocols like OSPF or EIGRP.
e. Employing Layer 3 switches with fast forwarding allows for quicker packet processing and routing decisions within the core layer, enhancing overall network performance.
f. Utilizing Layer 3 routing to the core ensures that the core layer primarily handles routing tasks, which is more efficient than relying on Layer 2 switches for routing purposes.
Options A, E and F are answers.

Answer:According to the Cisco Enterprise Campus Infrastructure document1, the following are three best practices used in the core layer:
Use routing with no Layer 2 loops. This eliminates the need for Spanning Tree Protocol (STP) and improves convergence and scalability.
Use Layer 3 switches with fast forwarding. This enables high-performance switching and routing of packets at wire speed.
Use two equal-cost paths to every destination network. This provides load balancing and redundancy for optimal network performance and availability.

Answer:
The correct answer is: The instructions are not correctly ordered.
Explanation:
The instructions are not correctly ordered because to pay the cashier, you first have to select your purchases.
The correct order for the instructions:
The instructions are not correctly ordered.
The given set of instructions is not in a logical order.
In the given set of instructions, "Select your purchases" should come before "Pay the cashier".
The instructions should have been:
Drive to the store Select your purchases Pay the cashier Drive home The given set of instructions is neither ambiguous nor inefficient.
It has a clear understanding of what the user wants to convey and direct the user to perform the desired action correctly within the given parameters.
A set of instructions should always be unambiguous, clear, and concise for users to perform the desired action correctly.
A user should follow the given set of instructions to the T for obtaining the desired outcome.
To write an efficient set of instructions, a writer should use clear and concise language and should always arrange the steps logically in an appropriate order to avoid confusion.
The instructions should always start with an action verb to direct the user to perform the desired action.
Always write instructions in simple terms to provide clarity in understanding to the user.
