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 2

Match each procurement document to its purpose.

Accepted Answer

RFP: Requests proposals for complex requirements where price is not the only factor. These procurement documents are commonly used in project procurement management.

Answer

RFP: Requests price quotations for standard items

Answer

RFI: Invites bids for well-defined products

Question 3

A project manager is planning a new data center build. The organization requires high availability and low latency for critical applications. Which infrastructure component should be prioritized to meet these requirements?

Accepted Answer

Redundant network paths. Redundant network paths ensure that if one link or switch fails, traffic can immediately fail over to an alternate path, providing high availability. They also reduce latency by enabling load balancing across multiple links, which is critical for real-time applications. This directly addresses the requirement for both high availability and low latency in a data center build.

Answer

Additional storage arrays

Answer

Additional firewall appliances

Answer

Virtualization licenses

Question 4

During a server migration project, the team discovers that the new servers have a different CPU architecture than the old ones. The project manager must decide the best course of action. What should the project manager do first?

Accepted Answer

Assess the impact on existing applications and plan remediation. The project manager must first assess the impact of the CPU architecture change on existing applications because different instruction sets (e.g., x86 vs. ARM) can cause binary incompatibility, requiring recompilation or emulation. Proceeding without this analysis risks application failures, data corruption, or performance degradation. This aligns with the PMBOK risk management process of identifying and analyzing risks before planning a response.

Answer

Proceed with migration as planned, assuming compatibility

Answer

Revert to the original server architecture

Answer

Delay the project to retrain staff on the new architecture

Question 5

An IT project manager is tasked with deploying a new inventory management system. The project requires installing software on 100 workstations and training users. Which factor is most critical to include in the project schedule?

Accepted Answer

Dependency on hardware compatibility testing. Hardware compatibility testing is the most critical factor because the inventory management system may require specific hardware configurations (e.g., CPU architecture, RAM, storage, or network interface drivers) to function correctly. If workstations are incompatible, the entire deployment could fail, making this dependency a prerequisite that must be scheduled before or in parallel with software installation. Without verifying compatibility, the project risks costly rework or delays.

Answer

Time to create user manuals

Answer

Duration of user training sessions

Answer

Procurement lead time for network cables

Question 6

A project is implementing a new backup solution. The current infrastructure uses tape backups, and the new solution will use cloud storage. During planning, the team identifies that the internet bandwidth is insufficient for initial seed data transfer. What is the best approach to mitigate this risk?

Accepted Answer

Perform a physical seed transfer of the initial backup. When internet bandwidth is insufficient for the initial seed data transfer of a cloud backup solution, a physical seed transfer (e.g., shipping a hard drive or tape cartridge to the cloud provider) bypasses the bandwidth bottleneck entirely. This approach is commonly supported by major cloud providers (e.g., AWS Snowball, Azure Data Box) for large initial datasets, as it avoids prolonged transfer times and potential failures over limited connections.

Answer

Compress the backup data to reduce transfer size

Answer

Schedule the transfer during off-peak hours

Answer

Upgrade the internet connection to higher bandwidth

Question 7

A project team is evaluating cloud providers for a SaaS application. The provider must guarantee 99.99% uptime and support data sovereignty requirements. Which service level agreement (SLA) clause is most critical to review?

Accepted Answer

Data residency and location clauses. The question explicitly requires the provider to support data sovereignty, which mandates that data must be stored and processed within specific geographic boundaries. The SLA clause on data residency and location clauses (Option D) directly addresses this by defining where data centers are located and whether data can be moved across borders. Without this clause, the provider could store data in jurisdictions violating legal or regulatory requirements, making it the most critical clause to review.

Answer

Data encryption standards

Answer

Financial penalty for downtime

Answer

Incident response and escalation procedure

Question 8

A project manager is assigned to upgrade the firewall for a company with multiple branch offices. The project charter has been approved, but the budget is tight. Which cost control technique should the project manager use to ensure expenses remain within budget?

Accepted Answer

Earned value management (EVM). Earned value management (EVM) is the correct technique because it integrates scope, schedule, and cost data to provide objective performance metrics (e.g., Cost Performance Index, Schedule Performance Index) that allow the project manager to continuously monitor and control expenses against the approved budget. For a firewall upgrade with multiple branch offices, EVM helps detect cost overruns early by comparing planned value (PV), earned value (EV), and actual cost (AC), enabling corrective actions before the tight budget is exceeded.

Answer

Reserve analysis

Answer

Bottom-up estimating

Answer

Parametric modeling

Question 9

During a network upgrade project, a technician accidentally disconnects a critical switch, causing an outage. The project manager needs to update the issue log and communicate with stakeholders. Which communication method is most appropriate for notifying senior management of the outage?

Accepted Answer

Verbal briefing via phone call. A network outage is a critical incident requiring immediate escalation. A verbal briefing via phone call (B) is the most appropriate method because it provides real-time, synchronous communication, allowing senior management to ask clarifying questions and make urgent decisions. This aligns with ITIL best practices for major incident management, where speed and clarity are paramount.

Answer

Status report in the next weekly meeting

Answer

Project dashboard update

Answer

Email notification

Question 10

A project to migrate on-premises email to Office 365 is behind schedule. The project sponsor asks the project manager to add more resources to accelerate the timeline. The project manager should first:

Accepted Answer

Analyze the critical path and determine if resource addition will help. Adding resources to a project that is behind schedule can sometimes worsen the delay due to Brooks' Law, especially if the critical path involves tasks that are not parallelizable. The project manager must first analyze the critical path to determine if adding resources will actually reduce the duration of critical tasks, such as mailbox migration batches or DNS cutover steps, or if it will introduce coordination overhead that negates any gains.

Answer

Add two additional migration specialists immediately

Answer

Update the project schedule to reflect the new timeline

Answer

Reduce the project scope by deferring non-critical features

Question 11

Which TWO of the following are key components of IT infrastructure that a project manager should consider when planning a new software deployment? (Choose two.)

Accepted Answer

Storage area network (SAN). Server hardware (E) is a core IT infrastructure component because the physical compute resources—CPU, memory, and local disks—directly determine the capacity, performance, and compatibility of the new software deployment, so the project manager must factor in procurement, rack space, power, and cooling. A storage area network (B) is also key infrastructure since it provides block-level, high-availability shared storage over Fibre Channel or iSCSI that production databases and clustered applications typically require, affecting performance, redundancy, and backup design. By contrast, the project charter (A) is a project governance document, not infrastructure; status reports (C) are communication artifacts; and a help desk ticketing system (D) is a service-management application, not an infrastructure component the deployment itself depends on.

Answer

Project charter

Answer

Status reports

Answer

Help desk ticketing system

Question 12

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

Accepted Answer

Implement change control processes. Option A is correct because implementing change control processes ensures that modifications to scope, schedule, or configuration are formally reviewed, approved, and documented, preventing uncontrolled changes that can derail an infrastructure project. Option C is correct because identifying stakeholders and their requirements early aligns the project with business and technical needs, reduces late-stage surprises, and improves acceptance of the delivered infrastructure. Option E is correct because establishing a baseline for scope, schedule, and cost provides a reference point for measuring performance, detecting variances, and controlling the project through earned value or similar techniques. Option B is not a best practice because minimizing documentation increases risk, reduces traceability, and undermines knowledge transfer and auditability. Option D is not a best practice because avoiding risk management leaves the project exposed to unidentified threats and issues that can cause delays, cost overruns, or failures.

Answer

Minimize documentation to reduce overhead

Answer

Avoid risk management to save time

Question 13

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 14

A company is migrating from on-premise email to a cloud-based solution. The vendor changes the migration tool mid-project. Which project management document should be updated to track the impact on requirements?

Accepted Answer

Requirements traceability matrix. The requirements traceability matrix (RTM) links each requirement to its origin, design, testing, and delivery status. When the vendor changes the migration tool mid-project, the RTM must be updated to reflect how this change impacts each requirement—such as compatibility, data migration rules, or security controls—ensuring all requirements are still met and traceable.

Answer

Risk management plan

Answer

Project charter

Answer

Work breakdown structure

Question 15

A project is deploying a new virtualized server environment. The project manager receives a report that resource pooling is inefficient. Which technology can best improve resource utilization across the virtual hosts?

Accepted Answer

Hypervisor memory overcommitment. Hypervisor memory overcommitment allows a hypervisor to allocate more virtual machine (VM) memory to VMs than the physical RAM available on the host, relying on the fact that VMs rarely use their full allocated memory simultaneously. This directly improves resource utilization by enabling higher VM density per physical host, which is the core inefficiency in resource pooling. Technologies like VMware ESXi's transparent page sharing or KSM (Kernel Same-page Merging) further optimize this by deduplicating identical memory pages.

Answer

VLANs

Answer

Load balancing

Answer

RAID
