Which two logical router components span across all transport nodes? (Choose two.)
A . SFRVICE_ROUTER_TJER0
B . TIERO_DISTRI BUTE D_ ROUTER
C . D1STRIBUTED_R0UTER_TIER1
D . DISTRIBUTED_ROUTER_TIER0
E . SERVICE_ROUTER_TIERl

Answer: B C

Explanation:

According to the VMware NSX 4.x Professional documents and tutorials, NSX-T has two logical router components, namely the Services Router (SR) and the Distributed Router (DR). As the names imply, SR is where centralized services are provisioned such as NAT, DHCP, VPN, Perimeter Firewall, Load Balancing, etc., and DR performs distributed routing across all hosts participating in a given transport zone3. The DR component is present in both Tier-0 and Tier-1 logical routers, while the SR component is only present in Tier-1 logical routers or in active-standby mode of Tier-0 logical routers4. Therefore, the logical router components that span across all transport nodes are TIER0_DISTRIBUTED_ROUTER and DISTRIBUTED_ROUTER_TIER1.
