4A0-D01 Exam Dumps : Nokia Data Center Fabric Fundamentals Exam

Comprehensive and Detailed Explanation with Exact Extracts:

Options A, B, and C are Day 2+ operations:

A: Telemetry enables real-time monitoring.

B: Health analysis supports proactive maintenance.

C: Sandbox validates changes pre-deployment.

Extract from Nokia FSS Day 2 Operations Guide:

"Day 2+ includes telemetry-based monitoring, health analytics, and sandbox testing for upgrades/changes."

Option D is a Day 0 activity:

Fabric intents define initial design templates (Day 0), not ongoing operations.

Extract from Nokia FSS Lifecycle Management Guide:

"Fabric intents are used during Day 0 design to build templates. Day 2+ focuses on operational tasks like monitoring (A), health checks (B), and sandbox validation (C)."

Comprehensive and Detailed Explanation with Exact Extracts:

Options A, B, and C are part of ZTP autoboot:

A: DHCP assigns IP/gateway.

B/C: Scripts download images/RPMs from servers (HTTP/FTP).

Extract from Nokia SR Linux ZTP Guide:

"Autoboot triggers DHCP discovery for IP/gateway. The device then fetches a provisioning script (via DHCP/DNS) that downloads RPMs/images from HTTP/FTP servers."

Option D is NOT part of ZTP autoboot:

Fabric Services System (FSS) and its digital sandbox are separate tools for lifecycle management. ZTP does not auto-deploy them.

Extract from Nokia FSS Deployment Guide:

"FSS deployment requires manual setup or orchestration tools. The digital sandbox is not automatically deployed via ZTP autoboot."

Comprehensive and Detailed Explanation with Exact Extracts:

Option A (TRUE): Type 1 routes enable multi-homing functions.

Extract from Nokia EVPN Multi-Homing Guide:

"Type 1 Ethernet A-D routes signal reachability for an Ethernet Segment (ES) and enable fast convergence/aliasing in multi-homing."

Option B (TRUE): Type 4 routes facilitate DF election.

Extract from Nokia EVPN Fundamentals Guide:

"Type 4 Ethernet Segment routes advertise ESI and VTEP IP to peers for Designated Forwarder (DF) election, which prevents BUM traffic loops."

Option C (FALSE): The ESI is globally unique, not locally significant.

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

"The ESI must be unique network-wide and consistently configured on all leafs attached to the same multi-homed device. It is not locally significant."

Option D (TRUE): An ES defines the host connectivity model.

Extract from Nokia EVPN Multi-Homing Guide:

"An Ethernet Segment (ES) is a set of links connecting a single host (e.g., server) to one or more leafs for redundancy/load balancing."
