400-007 Exam Dumps - Cisco Certified Design Expert (CCDE v3.1)

Security design must be aligned with:

Business objectives (A): Security design must meet business needs without hindering operations.

Security policies and standards (B): Compliance with internal and external regulations is mandatory.

CCDE v3.1 teaches that security design always starts from business intent and policy compliance, not purely technical or scope-based factors.

Why other options are incorrect:

C & D: Security design applies to all environments, not just multi-site or new deployments.

—

B (Use only secure protocols): Management and administrative access to Internet edge routers must use secure protocols (SSH, SNMPv3, HTTPS) to prevent interception or unauthorized access.

E (Restrict administrative access): Limiting administrative access via interface ACLs and clear login banners ensures that only authorized personnel can access the system, satisfying compliance and security requirements.

Other options explained:

A: Filtering infrastructure IP space is good hygiene but not directly related to compliance.

C: Logging is valuable for operations and incident response but not a compliance control by itself.

D: EBGP advertisements relate to routing policy, not compliance regulation.

A (Roaming delay):Voice requires seamless roaming with minimal handoff delay to avoid call drops.

B (Uniform radio coverage):Consistent signal coverage is essential for maintaining voice call quality throughout the facility.

Other options explained:

C: High channel utilization affects capacity but not directly the initial readiness assessment.

D: Latency is important but typically captured during ongoing performance testing, not pre-assessment.

E: TX power changes indicate instability but are not primary readiness criteria.

C: GLOP addressing is defined in RFC 2770, assigning a portion of the 233.0.0.0/8 range for each AS based on their 16-bit ASN. This allows each AS to use a /24 of globally unique multicast addresses without coordination from IANA.

Other options:

A: 239.0.0.0/8 is the administratively scoped multicast address space.

B: 224.0.0.0/24 is reserved for local link-scoped protocols (e.g., OSPF, RIP).

D: 232.0.0.0/8 is the Source-Specific Multicast (SSM) range.

==========

Automation: The execution of individual tasks or configurations without manual intervention.

Orchestration: The coordination and sequencing of multiple automation tasks into structured workflows to achieve complex operational goals.

Why other options are incorrect:

B, C, D: They incorrectly define orchestration as either partially manual, parallel execution, or limited to commercial tools, which is not accurate in design principles.

—

A: FabricPath assigns a specific multicast (S,G) flow to one tree. A single (S,G) does not get load-balanced across multiple trees.

E: Overall multicast traffic across multiple (S,G) groups is distributed across multiple FabricPath trees, providing general load balancing and efficient link utilization across the fabric.

Why other options are incorrect:

B: Traffic load per tree may not be uniform due to different group distributions.

C: The assignment is done by the ingress switch based on hashing, not all leaf nodes assign the same tree.

D: Individual (S,G) flows do not get load-balanced across trees.

Agile project management supports:

Frequent updates and iterative feedback loops

Flexibility to accommodate evolving requirements

Continuous customer collaboration and transparency

This methodology is ideal for projects where scope may shift and customer involvement is essential. In contrast:

Waterfall is linear and rigid

Phased delivery segments milestones but limits change midstream

“Three principles” is not a recognized methodology in this context

Agile aligns with modern IT deployment models and is supported in CCDE methodology as a business-aligned and adaptive design execution strategy.
