In a multi-AS underlay design:

You are involved in a 2-Tier L2 Data Center Design with the following details: * CX 8325 100G Core Switches * CX 10000 48-P 25G Access Switches * 100G SR4 Optical connections between Core and Access In this design, both the Core Layer and Access Layer consist of pairs of switches configured in VSX for HA. Core Switches = VSX Pairs of CX 8325 32-port 100G switches (B-F airflow) Each pair uses: * 2 x 100G QSFP28 1M DACs for ISL * 1 x 100G QSFP28 1M DAC for Keepalive * 2 x 100G QSFP28 SR4 Optic to each access switch Each Core switch has 13 available 100G QSFP28 interfaces. What is the maximum number of racks supported by this design?
