PK0-005 Basics of IT Infrastructure and IT Project Management Practice Test 2 — 15 Questions

Question 1

A team is implementing a disaster recovery plan that includes replication to a secondary data center. Which metric should the project manager prioritize defining in the DR plan?

Accepted Answer

Recovery time objective (RTO). The Recovery Time Objective (RTO) defines the maximum acceptable downtime after a disaster, directly dictating the speed of failover to the secondary data center. In a replication-based DR plan, the RTO determines whether synchronous or asynchronous replication is used and how quickly systems must be brought online. The project manager must prioritize this metric to align recovery speed with business continuity requirements.

Answer

Mean time between failures (MTBF)

Answer

Recovery point objective (RPO)

Answer

Mean time to repair (MTTR)

Question 2

During a server migration project, the team discovers that the new hardware requires a specific firmware version not currently installed. The project schedule is tight. What is the best course of action?

Accepted Answer

Update firmware immediately and adjust schedule. The firmware is a prerequisite for the new hardware to function correctly; proceeding without it risks incompatibility, instability, or hardware failure. Updating the firmware immediately and adjusting the schedule is the only viable path that ensures the migration is technically sound. The project schedule is tight, but the firmware update is a necessary step that cannot be skipped or deferred without jeopardizing the migration's success.

Answer

Use alternative hardware that supports current firmware

Answer

Proceed with migration and apply firmware post-migration

Answer

Defer the project until firmware is available

Question 3

A data center upgrade project requires redundancy for critical systems. Which three components should be redundant? (Choose three.)

Accepted Answer

Power supply. Option C (Power supply) is correct because redundant PSUs allow a server to keep running if one power supply or its feed fails, typically paired with separate power circuits. Option D (UPS) is correct because an uninterruptible power supply provides battery-backed power during outages and conditions the power, protecting critical systems until generators start or shutdown completes. Option E (Network switch) is correct because redundant switches (often in a stacked or MLAG/VPC configuration) eliminate a single point of failure in the data path and maintain connectivity if one switch fails. Option A (RAID controller) is not marked correct because RAID redundancy is about disk fault tolerance, and a single controller can still be a single point of failure unless a second controller is specifically added. Option B (Server chassis) is not marked correct because a chassis is a physical enclosure, not a component typically duplicated for redundancy within a single server.

Answer

RAID controller

Answer

Server chassis

Question 4

A project involves upgrading the network core switches to support higher throughput and new routing protocols. The project manager schedules a cutover during a weekend maintenance window. On Friday evening, the team discovers that the new switches do not have the correct software license for the advanced routing protocols required per the architecture. The current old switches are still functional. The project manager must decide the best course of action.

Accepted Answer

Postpone the cutover and request expedited delivery of the license.. The new switches lack the required software license for the advanced routing protocols (e.g., BGP, OSPF, or EIGRP) specified in the architecture. Attempting the cutover without the license would violate the design requirements and could lead to routing failures or security gaps. Postponing the cutover and requesting expedited delivery ensures the network upgrade is performed correctly without compromising functionality or stability.

Answer

Use open-source routing software as a temporary workaround on the new switches.

Answer

Proceed with cutover using basic routing and add the license later.

Answer

Fall back to the old switches and reschedule the cutover for a later date.

Question 5

A project manager is planning the network cutover for a new branch office. The project charter requires that the branch remain reachable even if its primary WAN circuit fails, and that the failover be validated before go-live. Which TWO activities should the project manager include in the cutover plan? (Choose two.)

Accepted Answer

Configure a floating static route with a higher administrative distance on the backup circuit.. Meeting the redundancy requirement takes both a mechanism and proof that it works: a floating static route supplies the backup path, and a scheduled failover test with documented results supplies the validation the charter demands. DHCP lease tuning, jumbo frames, and firewall replacement address addressing, performance, or security concerns, none of which keep the branch reachable when the primary WAN circuit fails.

Answer

Enable jumbo frames on all branch access switches to reduce failover latency.

Answer

Increase the DHCP lease time to 30 days so clients retain addresses across the outage.

Answer

Replace the branch firewall with a next-generation model that supports deep packet inspection.

Question 6

A project manager is planning a hybrid cloud deployment where the on-premises data center must connect securely to a cloud provider's virtual private cloud (VPC). The project sponsor is concerned about encryption for data in transit and wants to avoid using the public internet for this connection. Which solution should the project manager recommend?

Accepted Answer

Dedicated private network connection such as AWS Direct Connect or Azure ExpressRoute. The correct solution is a dedicated private network connection such as AWS Direct Connect or Azure ExpressRoute because it provides a private, dedicated link that bypasses the public internet, meeting the sponsor's requirement for secure, encrypted data in transit. Other options either rely on the public internet or are not designed for site-to-site data center connectivity. This ensures both security and performance for the hybrid cloud deployment.

Answer

Public internet with HTTPS

Answer

Site-to-site VPN using IPsec

Answer

Remote desktop gateway with TLS

Question 7

A project manager is leading a project to upgrade the network infrastructure of a hospital. The project involves replacing older switches with new ones that support Power over Ethernet (PoE) for IP cameras and wireless access points. During the planning phase, the project manager needs to ensure that the new switches can provide sufficient power to all devices. Which standard should the project manager verify that the switches comply with to ensure interoperability and adequate power delivery?

Accepted Answer

IEEE 802.3at. IEEE 802.3at (PoE+) is the correct standard because it delivers up to 30 watts per port, enough for typical hospital devices like IP cameras and wireless access points. It ensures interoperability and sufficient power, and is backward compatible with older PoE devices. Verifying this standard helps avoid power shortages and ensures reliable operation of critical network equipment.

Answer

IEEE 802.3af

Answer

IEEE 802.1Q

Answer

IEEE 802.3az

Question 8

A project manager is planning the migration of an on-premises data center to a colocation facility. The project sponsor is concerned about the cost of network connectivity and wants to ensure that the project uses a cost-effective, dedicated connection between the company's main office and the colocation site. Which connection type should the project manager recommend?

Accepted Answer

Point-to-point leased line. The sponsor requires a dedicated, cost-effective connection between two specific sites. A point-to-point leased line provides a private, dedicated circuit with predictable performance at a lower cost than MPLS or Metro Ethernet for a single link. A site-to-site VPN is not dedicated, and MPLS and Metro Ethernet are typically more expensive and feature-rich than needed here.

Answer

MPLS

Answer

Site-to-site VPN

Answer

Metro Ethernet

Question 9

A project manager is overseeing the deployment of a new file server for a small business. The business requires that files be accessible from both Windows and Linux workstations. The project manager must choose a file-sharing protocol that allows seamless access from both operating systems without additional client software. Which protocol should the project manager implement?

Accepted Answer

Server Message Block (SMB). SMB is the correct protocol because it is natively supported on both Windows and Linux (via Samba), allowing seamless file access without additional client software. It provides file locking, permissions, and performance suitable for a small business. NFS is more Linux-centric, while FTP and SSH do not offer the same integrated file-sharing experience.

Answer

Network File System (NFS)

Answer

File Transfer Protocol (FTP)

Answer

Secure Shell (SSH)

Question 10

A project manager is leading the migration of an on-premises data warehouse to a cloud-based platform. The project involves multiple vendors and internal teams. The project manager needs to ensure that all parties understand their responsibilities for deliverables, timelines, and acceptance criteria. Which document should the project manager use to formally define this information?

Accepted Answer

Contract. A contract is the formally binding agreement that defines deliverables, timelines, acceptance criteria, and responsibilities for all parties. In a multi-vendor data warehouse migration, contracts provide the legal framework the project manager uses to manage performance and enforce obligations. An MOU is non-binding, an SLA focuses on service performance, and an SOW is typically incorporated into a contract rather than standing alone as the enforceable document.

Answer

Statement of work (SOW)

Answer

Service level agreement (SLA)

Answer

Memorandum of understanding (MOU)

Question 11

A project manager is overseeing the implementation of a new customer relationship management (CRM) system. The vendor requires access to the company's internal network to install and configure the software. Which of the following is the BEST practice to ensure security while allowing vendor access?

Accepted Answer

Set up a VPN connection with two-factor authentication. Setting up a VPN connection with two-factor authentication is the best practice because it creates an encrypted tunnel over the internet, ensuring data confidentiality and integrity, while two-factor authentication adds an extra layer of security beyond just a password. This approach allows the vendor to access only the internal network resources necessary for installation and configuration, without exposing the entire network to unauthenticated or unencrypted access.

Answer

Provide the vendor with access to the guest Wi-Fi network

Answer

Allow the vendor to use remote desktop protocol (RDP) directly over the internet

Answer

Create a local user account with administrative privileges for the vendor

Question 12

A project manager is leading a project to upgrade the storage area network (SAN) for a hospital's electronic health records (EHR) system. The current SAN is reaching capacity and has performance issues during peak hours. The new SAN must support high availability with synchronous replication between two data centers located 10 km apart. The project budget is tight, and the timeline is aggressive. During a risk assessment, the project manager identifies that the fiber optic cable between the data centers is owned by a third-party provider and has a history of outages. The project sponsor is concerned about meeting the go-live date and asks the project manager to recommend a course of action to mitigate the risk of cable outages affecting the SAN replication. Which of the following is the BEST course of action?

Accepted Answer

Work with the fiber provider to install a second, diverse fiber path between the data centers. The risk is specifically a single point of failure in the fiber path between data centers. Installing a second, diverse fiber path eliminates this single point of failure, ensuring synchronous replication can continue even if one cable is cut. This directly addresses the sponsor's concern about go-live delays due to cable outages, without changing the replication mode or adding unnecessary hardware.

Answer

Purchase redundant SAN controllers to provide failover in case of a controller failure

Answer

Increase the synchronous replication interval to reduce the impact of potential outages

Answer

Replace synchronous replication with asynchronous replication over the existing WAN connection

Question 13

You are the project manager for a mid-sized company that provides an online customer portal. The portal is hosted on a single virtual machine (VM) in the company's on-premises data center with 4 vCPUs, 16 GB RAM, and a 500 GB HDD. The VM runs Windows Server 2019 and hosts both the web server (IIS) and the database (SQL Server Express). Users have been reporting slow performance, especially during peak hours (10 AM - 2 PM). The system administrator notes that CPU usage spikes to 95% during those times, and disk I/O latency averages 50 ms. The company's budget is limited, and they want a cost-effective solution that can be implemented within two weeks. The project sponsor suggests migrating to the cloud, but the IT director is concerned about security and compliance. The company has no existing cloud infrastructure or virtual private network (VPN) to the cloud. You need to propose a solution that improves performance without incurring high costs or long delays. Which of the following is the BEST course of action?

Accepted Answer

Create two separate VMs: one for the web server with 2 vCPUs and 8 GB RAM, and one for the database with 2 vCPUs and 8 GB RAM. Replace the HDD with an SSD on both VMs.. Separating the web server and database onto two VMs eliminates resource contention between IIS and SQL Server Express, which is the root cause of the CPU and I/O spikes. Replacing the HDD with SSDs reduces disk I/O latency from 50 ms to under 1 ms, directly addressing the performance bottleneck. This solution is cost-effective and can be implemented within two weeks using existing on-premises hardware, without requiring cloud migration or VPN setup.

Answer

Migrate the entire portal to a public cloud provider using a lift-and-shift approach, and set up a VPN connection for security.

Answer

Upgrade the existing VM by adding more RAM and using a faster HDD with a larger cache.

Answer

Implement IIS compression and enable SQL Server data compression to reduce CPU and I/O load.

Question 14

Put the steps for creating a work breakdown structure (WBS) in the correct order.

Accepted Answer

Identify major deliverables, then decompose deliverables into smaller components, then assign WBS codes, then verify correctness and completeness, then document details.. The WBS process starts with identifying major deliverables, decomposing them, assigning codes, verifying completeness, and documenting details.
