Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q150-Q155):

NEW QUESTION # 150
You have been asked to design a high-density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

Answer: A,D


NEW QUESTION # 151
Which development model is closely associated with traditional project management?

Answer: D


NEW QUESTION # 152
What are two common approaches to analyzing and designing networks? (Choose two.)

Answer: A,E

Explanation:
* A (Bottom-Up Approach): Starts with the evaluation of current infrastructure (hardware, protocols, configurations), followed by design adjustments based on identified gaps.
* C (Top-Down Approach): Starts from business and application requirements, translating them into technical design and network architecture.
Both approaches are widely used in network design methodology depending on business requirements and organizational maturity, directly referenced in CCDE v3.1 design models.
Why other options are incorrect:
* B & D: These are not valid or recognized network design approaches.
* E: Three-tier is a network architecture model, not a design approach.

NEW QUESTION # 153
SD-WAN can be used to provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud over any type of IP-based underlay transport network. Which two statements describe SD-WAN solutions? (Choose two.)

Answer: A,B

Explanation:
SD-WAN design principles:
* C: Centralized policy, simplified management, and dynamic path selection improve operational efficiency, directly resulting in cost savings.
* D: SD-WAN provides centralized orchestration, automation, and zero-touch provisioning, simplifying deployment and scaling.
Why other options are incorrect:
* A: SD-WAN improves performance with features like dynamic path selection but cannot inherently prevent slow underlay performance.
* B: Many SD-WAN solutions logically separate control and data planes, but not all strictly follow full separation like traditional SDN.
* E: SD-WAN is typically hardware-agnostic but does not depend on specialized switching hardware.


NEW QUESTION # 154
An enterprise campus is adopting a network virtualization design solution with these requirements:
* It must include the ability to virtualize the data plane and control plane by using VLANs and VRFs
* It must maintain end-to-end logical path transport separation across the network
* Resources available grouped at the access edge
Which two primary models can this network virtualization design be categorized? (Choose two)

Answer: B,D

Explanation:
The question describes a network that requires virtualization at both control and data plane levels using VLANs and VRFs. This architecture aligns with:
Path isolation (A): Achieved using VRFs and VLANs, ensuring traffic separation at Layer 2 and Layer 3 across the entire network.
Group virtualization (C): Refers to grouping users or resources (such as departments or tenants) into isolated segments that remain logically separated throughout the campus fabric.
Other options explained:
B (Session isolation): More aligned with application or session-layer security, not data/control plane virtualization.
D (Services virtualization): Typically related to virtualizing network services (firewalls, load balancers).
E (Edge isolation): Not a standard design term in CCDE.
