PK0-005 Practice Test 37 — 15 Questions

Question 1

A company is deploying a new VoIP system. Which network infrastructure component is most critical for ensuring voice quality?

Accepted Answer

Switch QoS settings. Voice quality over VoIP is highly sensitive to latency, jitter, and packet loss. Switch QoS settings (e.g., 802.1p/DSCP marking, strict priority queuing) ensure that voice traffic is prioritized over data traffic, preventing delays and dropped packets that degrade call quality. Without proper QoS, even high-bandwidth links will suffer from poor Mean Opinion Scores (MOS).

Answer

Cable category

Answer

Switch port density

Answer

Firewall throughput

Question 2

A project manager is leading a team to develop a new mobile application. The project has a fixed budget and a strict deadline. During the execution phase, the stakeholder requests additional features that were not originally planned. Which project constraint is most directly affected by this request?

Accepted Answer

Scope. Adding features without adjusting time or cost increases scope, leading to scope creep. This directly affects the scope constraint.

Answer

Quality

Answer

Schedule

Answer

Cost

Question 3

At a certain point in the project, the earned value (EV) is $500, the planned value (PV) is $600, and the actual cost (AC) is $400. What is the schedule performance index (SPI)?

Accepted Answer

0.83. The Schedule Performance Index (SPI) is calculated as EV / PV. With EV = $500 and PV = $600, SPI = 500 / 600 = 0.8333, which rounds to 0.83. An SPI less than 1.0 indicates the project is behind schedule because less value has been earned than planned.

Question 4

A project manager is creating a document that defines the project's objectives, key stakeholders, high-level requirements, and initial budget. Which document is this?

Accepted Answer

Project charter. The project charter is the document that formally authorizes the project and defines high-level information such as objectives, key stakeholders, high-level requirements, and the initial budget. This aligns with the PMBOK Guide definition, where the charter provides the project manager with the authority to apply organizational resources to project activities.

Answer

Scope statement

Answer

Project management plan

Answer

Work breakdown structure

Question 5

A project team is deploying a new application, and the error log shows repeated connection refused errors. The database server is on a separate subnet. What is the most likely cause of this issue?

Accepted Answer

The database port is blocked by a firewall. The error 'connection refused' indicates that the application's TCP SYN packet to the database server was met with a TCP RST or no response, which typically occurs when a firewall drops or rejects the traffic. Since the database server is on a separate subnet, a network-layer access control list (ACL) or firewall rule is the most common cause of blocking the specific database port (e.g., 3306 for MySQL, 5432 for PostgreSQL, 1433 for SQL Server). This prevents the three-way handshake from completing, resulting in the connection refused error.

Answer

The database schema is missing a required table

Answer

The database credentials are incorrect

Answer

The application server has insufficient memory

Question 6

A project manager is assigned to a new software development project with clearly defined requirements and minimal expected changes. Which project management methodology is most appropriate for this scenario?

Accepted Answer

Predictive (Waterfall). Predictive (waterfall) methodology is suitable when requirements are stable and well-defined, as it follows sequential phases with fixed scope.

Answer

Kanban

Answer

Agile

Answer

Hybrid

Question 7

During the execution phase of a software development project, the team discovers a critical bug that was not identified during planning. The project manager needs to decide how to handle the bug without significantly impacting the project scope and timeline. Which action should the project manager take first?

Accepted Answer

Perform a root cause analysis and assess the impact on project constraints. The project manager should first perform a root cause analysis and assess the impact on scope, schedule, and cost before deciding on a course of action. This allows for an informed decision that minimizes disruption to the project. Option B is incorrect because escalating to the sponsor without analysis bypasses proper project management processes. Option C is incorrect because logging the bug and continuing without analysis could lead to larger issues later. Option D is incorrect because assigning additional developers without understanding the root cause may not effectively resolve the bug and could waste resources.

Answer

Escalate the issue to the project sponsor for immediate resolution

Answer

Log the bug in the issue tracker and continue with the original plan

Answer

Assign additional developers to fix the bug without delay

Question 8

Which TWO activities are typically performed during the initiation phase of a project?

Accepted Answer

Develop the project charter. Options A and C are correct. The initiation phase includes developing the project charter and identifying stakeholders. Option B is incorrect because the project schedule is developed during planning. Option D is incorrect because the work breakdown structure is created during planning. Option E is incorrect because the risk response plan is created during planning.

Answer

Develop the project schedule

Answer

Develop the work breakdown structure

Answer

Create the risk response plan

Question 9

A team uses a tool that clarifies roles by showing who is responsible, accountable, consulted, and informed for each task. Which tool is this?

Accepted Answer

RACI matrix. A RACI matrix is a responsibility assignment matrix that defines roles. Gantt charts show schedule. WBS decomposes work. Network diagrams show dependencies.

Answer

Work breakdown structure

Answer

Network diagram

Answer

Gantt chart

Question 10

Two project team members disagree on the technical approach for a critical deliverable. The project manager needs to resolve the conflict to avoid schedule delays. What is the best course of action?

Accepted Answer

Facilitate a meeting to discuss pros and cons and reach consensus. The project manager should facilitate a collaborative discussion to evaluate the technical merits of each approach, enabling the team to reach consensus. This aligns with conflict resolution best practices in project management, leveraging the team's expertise to find the optimal solution without imposing a decision that could undermine buy-in or quality. By addressing the disagreement directly, the PM prevents schedule delays while maintaining team cohesion and technical integrity.

Answer

Escalate the issue to the project sponsor

Answer

Immediately decide on the approach and direct the team

Answer

Split the work and let each member implement their own approach

Question 11

Match each acronym to its definition in project management.

Accepted Answer

PMP: Project Management Professional. The correct matches are PMP with Project Management Professional, WBS with Work Breakdown Structure, EVM with Earned Value Management, and ROI with Return on Investment. Common confusions include mixing up ROI and PMP definitions, or confusing WBS with EVM.

Answer

PMP: Return on Investment

Answer

WBS: Earned Value Management

Question 12

Based on the exhibit, which risk should the project manager address first?

Accepted Answer

Risk R01 (Network outage). The project manager should address Risk R01 (Network outage) first because it has the highest risk score (0.72), which is the product of its probability and impact. This indicates the highest priority for response. Option A is incorrect because highest probability alone does not determine priority without considering impact. Option B is incorrect because the type of response (mitigation) does not indicate priority level. Option C is incorrect because highest impact alone does not determine priority without considering probability.

Answer

Risk with highest probability (R01 or R04)

Answer

Risk with a mitigation response (R01)

Answer

Risk with highest impact (R01 or R02)

Question 13

A project is in the executing phase when a key stakeholder requests a new feature that was not part of the original scope. The project manager needs to handle this request appropriately. Which TWO actions should the project manager take? (Select TWO).

Accepted Answer

Consult the change control board for approval.. The correct actions are to submit a formal change request (E) and then consult the change control board (CCB) for approval (A). These steps follow the formal change control process to prevent scope creep and ensure proper evaluation. Implementing the change immediately (B) bypasses this process. Ignoring the request (C) damages stakeholder relationships. Updating the project charter (D) is inappropriate because the charter was created during initiation and should not be modified for scope changes during execution. Therefore, options A and E are correct.

Answer

Implement the change immediately to satisfy the stakeholder.

Answer

Ignore the request to avoid scope creep.

Answer

Update the project charter to include the new feature.

Question 14

Which THREE of the following are best practices for managing IT infrastructure projects? (Choose three.)

Accepted Answer

Implement change control processes. Implementing change control processes (A) is a best practice because IT infrastructure projects often involve complex, interdependent systems where unapproved changes can cause cascading failures, security vulnerabilities, or downtime. Formal change control ensures that all modifications are reviewed, tested, and documented before deployment, maintaining stability and compliance.

Answer

Minimize documentation to reduce overhead

Answer

Avoid risk management to save time

Question 15

A project manager is using earned value management. The project has a schedule variance (SV) of -$5,000. What does this indicate?

Accepted Answer

The project is behind schedule.. A negative schedule variance (SV = EV - PV) indicates that the earned value (EV) is less than the planned value (PV), meaning the project is behind schedule. In this case, SV = -$5,000 confirms the project has accomplished less work than planned at the measurement date.

Answer

The project is ahead of schedule.

Answer

The project is under budget.

Answer

The project is over budget.
