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

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."

The "baseline diff" command is used to compare the candidate configuration against the baseline datastore to see changes or conflicts, especially when multiple users are involved or to verify differences. It does not indicate that the user is unable to commit changes.

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)."
