This PK0-005 practice question tests your understanding of basics of it infrastructure and it project management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is deploying a new web server. Which TWO security measures should the project manager include in the project plan? (Choose two.)
UPS
Why wrong: UPS ensures power continuity, not security.
Load balancer
Why wrong: Load balancers distribute traffic but are not a direct security measure.
RAID array
Why wrong: RAID provides disk redundancy, not security.
Firewall rules
Firewall rules restrict unauthorized access to the web server.
TLS certificate
TLS encrypts communication between clients and the web server, ensuring data confidentiality.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Firewall rules
Firewall rules are essential for controlling inbound and outbound traffic to the web server, protecting it from unauthorized access and attacks. A TLS certificate enables HTTPS encryption, ensuring data confidentiality and integrity between clients and the server. Both are critical security measures that should be included in the project plan for a new web server deployment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
The trap here is that candidates often confuse high-availability or infrastructure components (UPS, load balancer, RAID) with security measures, but the question specifically asks for security measures, not availability or performance features.
Detailed technical explanation
Firewall rules operate at the network layer (Layer 3/4) or application layer (Layer 7) to filter traffic based on source/destination IP, port, and protocol; for a web server, rules typically allow TCP/443 (HTTPS) and TCP/80 (HTTP) while blocking all other inbound traffic. TLS certificates rely on public key infrastructure (PKI) and X.509 standards; the server presents a certificate signed by a trusted CA during the TLS handshake, enabling encrypted sessions and preventing man-in-the-middle attacks. In real-world deployments, misconfigured firewall rules or expired TLS certificates are common vulnerabilities that lead to breaches or service disruptions.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
