NEW QUESTION 33
Which two VMware recommendations should an architect follow when configuring top of rack (ToR) switches in an NSX-T Data Center environment? (Choose two.)
- A. Use only IPv4 addressing in all deployments.
- B. Configure switch ports with a Dynamic Trunking Protocol.
- C. Configure switch ports that connect to ESXi host manually as trunk ports.
- D. Modify the Spanning Tree Protocol to increase the time to transition to the forwarding state.
- E. Configure redundant physical switches to enhance availability.
Answer: C,E
Explanation:
Top of Rack Physical Switches
When configuring top of rack (ToR) switches, consider the following best practices:
- Configure redundant physical switches to enhance availability.
- Configure switch ports that connect to ESXi hosts manually as trunk ports. Virtual switches are passive devices and do not support trunking protocols, such as Dynamic Trunking Protocol (DTP).
- Modify the Spanning Tree Protocol (STP) on any port that is connected to an ESXi NIC to reduce the time to transition ports over to the forwarding state, for example using the Trunk PortFast feature found in a Cisco physical switch.
- Provide DHCP or DHCP Helper capabilities on all VLANs used by TEP VMkernel ports. This setup simplifies the configuration by using DHCP to assign IP address based on the IP subnet in use.
- Configure jumbo frames on all switch ports, inter-switch link (ISL), and switched virtual interfaces (SVIs).

NEW QUESTION 35
A Solutions Architect is working with a customer which wants to extend their traditional Telco IP/MPLS core network to an NFV cloud.
Which NSX-T Data Center feature can be recommended by the architect? (Choose the best answer.)
- A. Load Balancer
- B. Distributed IDS
- C. BGP
- D. EVPN
Answer: D
Explanation:
In NSX-T Data Center 3.0, EVPN is used to extend traditional Telco networks to NFV clouds:
- Telco virtual router use BPG to dynamically exchange tenant routing with NSX gateways.
- NSX gateways implement VRFs to provide isolation between tenants.
- NSX gateways support MP-BPG to interconnect Telco traditional networks with NSX virtual networks.
- VXLAN is the encaptulation supported to exchange traffic with the remote gateways.
