CompTIA Project+ PK0-005 Study Guide, Chapter 07

You are creating a document that describes the access rights to the financial system in your organization.

It defines access by roles and responsibilities and describes the approval process for obtaining access.

One of the rules stated in the document dictates that remote access to systems requires MFA.

Which of the following are true regarding this question?

(Choose two.)

• This question describes an operational security policy.

• This question describes a digital security policy.

• This question describes a process of verifying identity by requiring two or more forms of identification at sign-in.

• This question describes a form of data classification.

• This question describes a data security policy.

Answer explanation

This question describes a digital security policy.

Multifactor authentication uses at least two forms of verification of identity at the sign-in process

Your organization is involved in research and development of botanical cleaning products.
Your recent product has just received approval to display the @ (registered) symbol.

All potential employees must undergo a background check before being hired and again yearly on the anniversary of their hire date.

One of the laboratories contains top-secret research and only certain employees have access to this lab.

One of the employees on the project team has just been promoted and will be leaving the team to join their new functional area.

This team member previously had access to the top-secret lab, but their new role no longer requires this access.

Which of the following is not true regarding this question?

• The operational security policy outlines the process for background checks for employees.

• Access to the top-secret lab is outlined in the physical security policy.

• The new product has not been registered at the U.S. Patent and Trademark office.

• The physical security policy should outline the process for revoking access to the top-secret lab as soon as the employee is transferred to their new role.

Answer explanation

Registered products are those that have been Trademarked and registered with the U.S. Patent and Trademark office.

A stranger comes to your door posing as a census taker.

They look official in their bright Orange vest and have some type of tag or badge hanging from the vest, but you can't read what it says.

They begin to ask questions that become rather personal, including your household income on an annual basis, your birthdate, your health status, and more.

You become suspicious of this person and stop to think through what to do next.

Which of the following are true regarding this question?

• Due to your suspicion of this individual, you are classifying your answers as PII and refuse to answer.

• Due to your suspicion of this individual, you are classifying your answers as PHI and refuse to answer.

• 1. Due to your suspicion of this individual, you ask to see their badge before you decide to answer.

• Due to your suspicion of this individual, you are classifying your answers as need-to-know basis and refuse to answer.

• All of the answers are true.

Answer explanation

All of the options are true.

You may still decide to refuse to answer after viewing their badge, as option C describes.

You should always verify the identity of the person asking for personally identifiable information (PI).

You are asked to prepare an estimate for a project that involves planting new trees in the parking lot.

The trees cost $800 each, and the labor to install them is $75 per hour.

You are planting 10 new trees, and each tree takes one hour of labor to plant, stake, and water.

What is the estimated cost of the labor for this project, and which technique are you using to determine this estimate? (Choose two.)

• $8,000

• Three-point estimate

• Bottom-up method

• $750

• 1. Parametric method

Answer explanation

The labor, $75/hour, times 10 trees is $750.

This is the parametric method of estimating because you are multiplying the quantity times the rate.

Analogous estimating involves using estimates from similar projects, and three-point estimates use the average of three estimates

The total time it will take for one person to complete a task from beginning to end without taking into account holidays,

time off, or other project work, is known as this:

• Duration estimate

• Work effort estimate

• Bottom-up estimate

• Parametric estimate

Answer explanation

A work effort estimate or person-hour estimate is used to develop the cost estimates.

This is the amount of time it will take to complete the task from beginning to end without accounting for work breaks, holidays, and so on.

Duration estimates account for holidays, work breaks, and so on.

Bottom-up estimates are estimates for individual components of work that are rolled up into the overall estimate, and parametric estimates are usually derived by multiplying quantity by rate

A discretionary fund used by the project manager to cover the cost of possible adverse events during the project is known as which of the following?

• Management reserve

• Chart of accounts

• Contingency fund

• Cost baseline

Answer explanation

A contingency fund is an amount allocated to cover the cost of possible adverse events, and the project manager generally has the ability to use this fund.

The project manager does not usually have the authority to spend money from the management reserve.

The chart of accounts is a description of the accounts listed in the accounting ledger, and the cost baseline is the total expected cost for the project

You are developing a bottom-up cost estimate for the first phase of your project.

Which of the following is the most important input to complete this task?

• Historic data from a similar project

• 1. Chart of accounts

• The WBS

• The scope statement

Answer explanation

Bottom-up estimates start at the work package level of the WBS.

Each work package on the WBS for the first phase of the project is summed to come up with an overall estimate for this phase.

Historical data would be useful if you were using the analogous estimating technique.

The chart of accounts doesn't help at all with this exercise, and the scope statement will give you an understanding of what's detailed on the WBS, but it won't help with estimating

What is considered the most accurate estimate?

• Analogous estimate

• Bottom-up estimate

• Estimates based on expert judgment

• Parametric estimate

Answer explanation

Bottom-up estimates are the most accurate estimates, and analogous estimates are the least accurate.

Estimates based on expert judgment are analogous estimates.

Parametric estimates are only as accurate as the data you're using for the parametric model

You are asked to present and explain your project cost baseline.

All of the following are true except which one?

• The baseline will be used to track actual spending against the cost estimates.

• The baseline can be used to predict future project costs.

• The baseline is calculated and approved by the project manager.

• The baseline is the total expected cost for the project.

Answer explanation

The cost baseline is approved by the project sponsor, not the project manager

Your project task is complex, and you decide to use a three-point estimating technique.

Which of the following options determine the three-point estimate? (Choose three.)

• Quantity estimate

• Work package level estimate

• Pessimistic estimate

• Optimistic estimate

• Most likely estimate

Answer explanation

Three-point estimates are the average of the most likely, optimistic, and pessimistic estimates
