Which three VMware guidelines are recommended when designing VLANs and subnets for a single region...

RFC1918 Address Space (A)

VMwarerecommends using private IPv4 address rangesfromRFC1918. This ensures internal network segmentation without public exposure.

Allocatingone octet for region and another for functionhelps with structured IP management.

Subnet Sizing (D)

Using /24 subnetsis preferred inNSX-T designbecause:

Itsimplifies managementby offering256 usable IP addresses per subnet.

It preventsoverlapping IP issuesand ensuresbetter compatibility with firewalls and routers.

Floating Interface for VRRP/HSRP (E)

NSX-T supportsredundant gatewaysusingVRRP (Virtual Router Redundancy Protocol)orHSRP (Hot Standby Routing Protocol).

Thefloating IPacts as aredundant gateway, ensuringseamless failoverinmulti-gateway environments.

Incorrect Options:

(B - IPv6 RFC2460)→ NSX primarily usesIPv4for most enterprise deployments. IPv6 support is limited and requires additional configuration.

(C - /16 Subnets)→ Using/16 subnetsis impractical for micro-segmentation as it createslarger broadcast domainsand increasesnetwork overhead.
