Score Higher on Verified 4A0-D01 | Nokia Data Center Fabric Fundamentals Exam Questions with Answers

Comprehensive and Detailed Explanation From Exact Extract:

Option A: TRUE – Fabric intent is declaratively defined in YAML.

"FSS uses YAML-based declarative intent to define and manage fabric configurations."

— Nokia Fabric Services System User Guide, "Intent-Based Fabric"

Option B: FALSE – The Digital Sandbox is for pre-deployment validation, not performance monitoring.

"The Digital Sandbox simulates configurations for validation before deployment. Performance monitoring is handled by telemetry analytics, not the sandbox."

— Nokia FSS Deployment Guide, "Digital Sandbox"

Option C: TRUE – Telemetry is contextualized with intent.

"Telemetry data is correlated with fabric intent, providing context-aware insights."

— Nokia FSS Operations Guide, "Telemetry and Analytics"

Option D: TRUE – FSS is cloud-native for flexible integration.

"FSS’s cloud-native microservices architecture simplifies integration with customer ecosystems."

— Nokia FSS Architecture White Paper, "Cloud-Native Design"

Conclusion: Option B misrepresents the Digital Sandbox’s purpose.

Comprehensive and Detailed Explanation with Exact Extracts:

Option A (VNI is included): The IMET route explicitly carries the VNI (as the Ethernet Tag ID) to identify the Layer 2 domain.

Extract from Nokia EVPN-VXLAN Guide (Section: IMET Route):

"The IMET (Type 3) route includes the VNI (Ethernet Tag ID) to signal membership in a specific broadcast domain."

Option B (Flooding list is NOT included): The IMET route does not contain a flooding list. Each VTEP independently builds the flooding list by aggregating all received IMET routes for the same VNI (e.g., VTEP1 uses IMET routes from VTEP2 and VTEP3 to build its list).

Extract from Nokia SR Linux Fundamentals Guide (Section: EVPN BUM Handling):

"The flooding list for a VNI is dynamically constructed by each VTEP based on received IMET routes. The IMET route itself only advertises the sender's VTEP IP and VNI, not a pre-defined list of peers."

Option C (Route Distinguisher is included): The IMET route includes the MAC-VRF's Route Distinguisher (RD) to ensure uniqueness in the control plane.

Extract from Nokia EVPN Configuration Guide:

"Every IMET route carries the MAC-VRF's RD to distinguish overlapping VNIs across different network instances."

Option D (VTEP IP is included): The IMET route advertises the VTEP's IP address (via the PMSI Tunnel attribute) to establish the BUM traffic tunnel endpoint.

Extract from Nokia SR Linux Configuration Guide (Section: EVPN Routes):

"The IMET route includes the originating VTEP's IP address in the PMSI Tunnel field. This IP is used as the destination for VXLAN-encapsulated BUM traffic."

Exhibit Analysis:

The IMET routes (advertised by VTEP1, VTEP2, VTEP3) are shown.

Each VTEP's locally configured flooding list (e.g., VTEP1: [VTEP2, VTEP3]) is derived from received IMET routes, not embedded in the IMET route itself.

Comprehensive and Detailed Explanation with Exact Extracts:

Options A, B, and D are supported:

SR Linux users (A): Locally configured users for CLI/management access.

Regular Linux OS users (B): Native Linux users (e.g., admin) for host OS operations.

Remote users (D): Authenticated via AAA (TACACS+/RADIUS).

Extract from Nokia SR Linux System Management Guide:

"User types include SR Linux users (CLI access), Linux OS users (host system), and remote users (external AAA)."

Option C (Container users) is NOT supported:

SR Linux does not define "container users" as a distinct category. Containers (e.g., management container) share the host's user management.

Extract from Nokia SR Linux Security Guide:

"SR Linux does not provision separate user identities for containers. User access is managed at the host OS level or via SR Linux CLI, with no container-specific user type."
