Cisco 400-007 Exam Questions
- Topic 1: Business Strategy and Design: This section of the exam measures skills of a Network Architect, focusing on how business strategy drives network design and optimisation. Candidates are expected to understand the impact of project methodologies such as waterfall and agile, and how considerations like business continuity, RPO, ROI, CAPEX/OPEX and risk/reward influence technical decisions in solution design.
- Topic 2: Control Data, Management, Operational Design: Targeting the Network Automation Specialist, this domain covers end to end IP traffic flow across rich environments, involving the separation of data, control, and management planes. Candidates must demonstrate knowledge of centralized, decentralized, and hybrid control models, and explain how automation and orchestration, including API integration, model-driven management, and CI/CD evolution, support controller-based and software-defined architectures such as SD WAN and network fabric implementations.
- Topic 3: Network Design: This section is designed for a Senior Network Designer and assesses the ability to create resilient, scalable, and secure modular networks in both traditional and software-defined environments. It emphasises the translation of technical, operational, and business constraints into robust implementation and migration strategies that accommodate application behaviour and organisational requirements.
- Topic 4: Service Design: This domain, aimed at a Cloud Network Engineer, examines how modular network design supports diverse IP-based applications including voice, video, replication, IoT, and storage. Candidates must consider operational resilience, cloud/hybrid connectivity, data governance needs (sovereignty, compliance), and service placement models like SaaS, PaaS, IaaS, direct connects, and WAN integration under regulatory constraints.
- Topic 5: Security Design: This part of the exam measures the expertise of a Network Security Architect and covers the integration of security within network design. It includes segmentation, access control, visibility, policy enforcement, and application of the CIA triad within modular architectures. Professionals must also understand how to align security with regulatory requirements relevant to network governance.

Company XYZ must isolate and encrypt production traffic to meet HIPAA compliance. The current WAN includes MPLS and P2P links.
What is the fastest deployment option?
A bank recently had their security compromised during an initial key exchange between devices using a symmetric cryptography algorithm, and as a result the key was revealed/leaked. Going forward, they want to ensure that key exchanges are performed using asymmetric cryptography algorithms. Which algorithm offers the desired functionality?
Refer to the exhibit.
An engineer has been asked to redesign the traffic flow toward AS 111 coming from AS 500. Traffic destined to AS 111 network 91.7.0.0/16 should come in via AS 100, while traffic destined to all other networks in AS 111 should continue to use the existing path. Which BGP attributes are best suited to control this inbound traffic coming from BGP AS 500 into the 91.7.0.0/16 network?
Inbound traffic engineering is best controlled by manipulating how external ASes view your routes.
AS path prepending on the 91.7.0.0/16 prefix towards AS 200 makes AS 500 prefer the less-prepended path through AS 100.
This allows granular inbound control for that specific prefix while leaving the rest of the traffic unchanged.
Why other options are incorrect:
B: Extended community is not used for direct inbound path manipulation.
C: Local preference affects outbound traffic, not inbound path selection by remote ASes.
D: MED is only compared between the same AS; it won't affect AS 500's choice.

Which design method is achieved by layering the network control plane above a redundant physical infrastructure?
A customer asks you to perform a high level review of their upcoming WAN refresh for remote sites The review is specially focused on their retail store operations consisting of 500+ locations connected via mutlipoint IPsec VPN solution. Which routing protocol would be valid but would also be the most restrictive for the expansion of this deployment model?
