Multichassis Link Aggregation in a Virtual Chassis: https://juni.pr/3pBu6cP

A node/switch can be configured as either MC-LAG or VCF/VC, not both at the same time. So if by the question - is already a VCF - it can't be a member of MC-LAG. RTG - Redundant Trunk Groups is a replacement for Spanning Tree (so is VCF). Ethernet Segment Identifiers serve a different purpose (It's is a method of connecting a CPE to two logically different PE's) We are left with LAG which is a bundle of ports on one logical device. The correct answer is: C: LAG

I think the answer is LAG, as the VCF is like one logic device, so we do not need mc-lag here. ESI is completely about different area.

dont think mclag will solve the problem. should be D. ESI An ESI is configured on a per-interface basis; all interfaces configured with the same ESI, on any devices within the same EVPN domain, appear as part of the same L2 segment or LAG. On top of an ESI, it’s also possible to configure LACP to provide better fault detection.

It's a VCF, so you can create an LAG accross multiple Leaves, the given answer is correct

A) MC_LAG

The answer is should be A. as the question has mention, need link redundancy but not the same port, so MC-LAG can provide that.
