Network Design Technical Requirements for Expansion

400-007 By islever Editorial Last updated

Short answer

DE Implement high availability for critical voice traffic and a unified infrastructure supporting voice, video, data, and wireless.

Question

A national retail company is expanding their business by adding several international sites in the next 12 months. With their current IT infrastructure, they face a high number of expenses in managing and maintaining their two current data and voice networks. In addition, the business wants to invest in technologies that offer enhancements to business activities and increase employee productivity. Which two technical requirements should be considered during the network design phase? (Choose two.)
  1. Ability to provide isolation between the traffic of guests and internal staff (for wired and wireless) to comply with the standard security policy of the organization.
  2. Provide traffic isolation to meet the information security requirements.
  3. Capability to support introducing new remote sites to the network without any redesign
  4. Increase high availability to support critical traffic such as voice. Correct Answer
  5. Unified infrastructure that supports voice, video, data, and wireless Correct Answer

Key Takeaways

The question tests the ability to distinguish between business goals (expansion, cost reduction) and specific technical design requirements (infrastructure type, availability).

This question identifies the correct technical requirements for a retail company expanding internationally, focusing on unified infrastructure and high availability. The page clarifies why scalability is not considered a primary 'technical' requirement in this specific exam context.

Common mistake: Many learners select C because expansion is mentioned, but it is often classified as a design principle or business goal rather than a direct technical specification like D or E.

Expert Analysis

Why the Answer Is Correct

The correct options are D and E. Option E addresses the need to invest in technologies that enhance business activities and reduce expenses by consolidating voice, video, data, and wireless into a unified infrastructure. Option D directly addresses the need to support critical traffic such as voice, which is essential for maintaining productivity and operational continuity during expansion.

Why the Other Options Are Wrong

Option A and B focus on security isolation. While important, the prompt emphasizes enhancing business activities and reducing management expenses, making unified infrastructure a higher priority. Option C refers to the capability to add sites without redesign. This is a design goal or benefit, not a specific technical requirement of the network itself. The term 'technical requirements' typically points to specifications like protocols, hardware capabilities, or service levels (like QoS/HA), rather than architectural flexibility.

Community Comment Notes

Several commenters correctly identified DE, noting that C is a business outcome rather than a technical spec. One user highlighted that E reduces costs and enhances activity, aligning with the prompt's goals. Another user pointed out that D supports critical traffic, which is vital for a retail operation. Some users chose CE, arguing that scalability is key, but the majority consensus and expert analysis favor DE as the more precise technical answer.

Exam Strategy

Focus on keywords like 'technical requirements' versus 'business goals'. When asked for technical requirements, look for concrete specifications (e.g., unified infrastructure, high availability) rather than abstract benefits (e.g., scalability, ease of management).

Frequently Asked Questions

Why is C not a technical requirement?

Scalability is a design characteristic or business goal. Technical requirements usually specify concrete capabilities like HA or unified services.

Does the question mention security needs?

No, it focuses on cost reduction, productivity, and supporting new sites. Security is not the primary driver here.

    It should be DE because it says "technical requirements" C is not a technical requirements.

    Two --technical-- requirements for the network design: C. Capability to support introducing new remote sites to the network without any redesign: This flexibility is crucial for the company's planned expansion and will avoid costly network changes in the future. E. Unified infrastructure that supports voice, video, data, and wireless: This will significantly reduce the complexity and cost of managing two separate networks (data and voice).

    A & E. Retail national and international operations -> PCI -> "Maintain an information security policy" -> option A, Not option B because PCI does not require traffic isolation, but that is not a limitation to include such requirement in their policy. option E because of the savings of a single multiservice network
  4. RLCCIRCUIT 👍 1
    It said 1. site expanding, so C is right. 2. high expenses, so D will cut the cost. It doesn't mention any critical traffic that needs to be improved or any security issue from the existing setup. So A, B, D will not apply.

    I vote for D and E. E because doing so would enhance business activity and reduce the cause of large expenses. D because it is necessary to keep the business robust.

    I also vote for D & E; the question is about the technical requirements. C is not technical.
  2. Seawanderer 👍 1
    I’d say C rather than D to support the additional sites
