Answer:

It is not possible.

Explanation:

In this example, we need to accommodate 473 computers for six clients that are 473 IP addresses.

For this request just we have /22 IPv4 address blocks, this mean

22 red bits 11111111111111111111110000000000 <--- 10 host bits

We must increase red bits to 25, we need these 3 bits to create 6 sub red, in this case, 2^3 = 8 sub red.

Why did we ask 3 bits? Because if we ask only 2, 2^2 = 4, and we need 6 sub red.

25 red bits 11111111111111111111111110000000 7 host bits

In this case, we need more than 260 computers, but just we have 7 bits, this means.

2^7 = 128 and just one customer needs 260, for that is impossible.

Answer:Let’s start with a review of the essential steps in the career planning process.

Career Planning

Shepard and Mani define career planning “as an ongoing process through which an individual sets career goals and identifies the means to achieve them” (2013, p. 14). It is through career planning that a person evaluates abilities and interests, assesses values and personality, considers alternative career opportunities, establishes career goals, and plans practical developmental activities.

Career planning requires individuals to understand themselves and their values, interests, and skills. It is also an ongoing process, one that must be repeated with changes in employment and life circumstances. As you gain more experience and knowledge, the process will begin anew.

This section reviews the five essential steps of career planning, which are based on our research and input from industry experts:

Conduct a self-assessment

Research the labour market

Create your career search toolkit

Put your career campaign into action

Engage in networking

Let’s start at step one.

Step One: Conduct a Self-Assessment

Self knowledge is the key to choosing a career. It can be overwhelming to begin the process of self-assessment. However, if done well at the start, the likelihood of securing work that has meaning, purpose, and fulfillment is far greater. Understanding your preferences, knowing your strengths, and honestly facing the areas you need to develop are the first steps for effective self-assessment.
