Answer: B
Explanation: Alignment ensures that the network design delivers value by addressing both technical and
business requirements.
Question 5: Which design consideration ensures a network can continue operating during hardware
failures?
A. Scalability
B. Fault tolerance
C. Cost optimization
D. Resource allocation
,Answer: B
Explanation: Fault tolerance is the ability of a network to maintain operations even when components
fail.
Question 6: How does high availability differ from redundancy in network design?
A. They are the same concept
B. High availability focuses on uninterrupted service, while redundancy provides backup components
C. Redundancy is only about cost savings
D. High availability is not part of network design
Answer: B
Explanation: High availability ensures continuous operation, and redundancy provides additional
components to achieve that goal.
Question 7: In topology design, why is a site survey crucial?
A. It determines the brand of equipment
B. It provides an understanding of the environmental constraints
C. It sets pricing for the project
D. It limits network protocols
Answer: B
Explanation: A site survey assesses physical conditions and environmental constraints essential for
proper design planning.
Question 8: Which LAN topology is most commonly used in modern enterprise networks?
A. Ring topology
B. Mesh topology
C. Star topology
D. Bus topology
Answer: C
Explanation: A star topology is widely used due to its simplicity and ease of management.
Question 9: What aspect of network design does scalability address?
A. Cost minimization only
B. The ability to add more users and devices without performance loss
C. Limiting expansion to avoid complexity
D. Reducing network security
Answer: B
Explanation: Scalability ensures that the network can grow and adapt to increasing demands.
Question 10: Which best practice in project scope definition helps prevent design drift?
A. Ignoring stakeholder feedback
B. Clearly defined requirements and deliverables
C. Minimal documentation
D. Relying solely on vendor recommendations
Answer: B
Explanation: Well-defined requirements and clear deliverables ensure that the project stays on track.
,Question 11: In a network design, what is the significance of resource allocation?
A. It increases the number of protocols
B. It helps in budgeting and ensuring optimal performance
C. It minimizes security measures
D. It discourages scalability
Answer: B
Explanation: Effective resource allocation ensures that funds and equipment are optimally distributed
for performance.
Question 12: What does “flexibility” in network design typically refer to?
A. The physical movement of devices
B. The ability to adapt to changing technologies and requirements
C. The capacity to reduce network speed
D. The elimination of redundant components
Answer: B
Explanation: Flexibility allows a network design to evolve with emerging technologies and shifting
business needs.
Question 13: Which phase of PPDIOO is primarily concerned with performance testing and
adjustments?
A. Operate
B. Design
C. Optimize
D. Prepare
Answer: C
Explanation: The Optimize phase focuses on continuous performance improvements based on testing
and real-world usage.
Question 14: What role does cost optimization play in network design?
A. It ensures the network is as inexpensive as possible regardless of performance
B. It balances expenditure with performance and scalability needs
C. It limits the use of modern technologies
D. It focuses solely on reducing vendor contracts
Answer: B
Explanation: Cost optimization finds a balance between spending and achieving desired network
performance and scalability.
Question 15: In designing WAN topologies, what is the primary advantage of MPLS?
A. It is the cheapest solution
B. It allows for efficient routing and supports QoS
C. It eliminates the need for any security measures
D. It restricts traffic to a single protocol
Answer: B
Explanation: MPLS is popular in WAN designs because it efficiently routes traffic and supports quality-of-
service guarantees.
, Question 16: How does environmental consideration during a site survey affect topology design?
A. It has no impact
B. It helps determine the physical layout and cabling needs
C. It only influences security policies
D. It dictates software licensing
Answer: B
Explanation: Environmental factors such as building layout, interference, and physical space impact how
a network is physically designed.
Question 17: What is the purpose of aligning technical solutions with business needs?
A. To increase the project timeline
B. To ensure that the network supports overall business goals
C. To complicate the network design
D. To disregard performance metrics
Answer: B
Explanation: Alignment between technical design and business goals ensures that the network
effectively supports organizational objectives.
Question 18: Which PPDIOO phase directly involves risk management and contingency planning?
A. Design
B. Operate
C. Plan
D. Optimize
Answer: C
Explanation: The Plan phase includes risk management and contingency planning to prepare for
potential issues.
Question 19: What is one major benefit of using a standardized design methodology like PPDIOO?
A. It increases design complexity
B. It creates a repeatable and structured approach to network design
C. It removes the need for documentation
