NEW QUESTION # 11
A Solutions Architect is assisting a service provider with designing an NSX-T Data Center solution for these environments:
Virtual Data Center to Virtual Data Center connectivity
Tenant workload on-boarding to Virtual Data Centers.
These requirements must be met:
scalability across 5 data centers
all sites have a latency of 180ms
MTU between sites is 1800
bandwidth is 100Mbps between sites
multi-tenancy
Which two selections should the Solutions Architect propose to the service provider? (Choose two.)
- A. Configure IPSec VPN for Tenant T0 gateways for Virtual Data Centers connectivity
- B. Configure Remote TEPs for stretching network services between Virtual Data Centers.
- C. Configure IPSec VPN for Tenant T1 gateways for Virtual Data Centers connectivity.
- D. Utilize L2 VPN for workloads on-boarding from on-premises to Virtual Data Centers.
- E. Utilize SSL VPN for workloads on-boarding from on-premises to Virtual Data Centers.
Answer: C,D
Explanation:
As mentioned, using Federation for five sites is not possible yet. Therefore, we have to setup L2VPN. IPSec (needed by L2VPN) can be established from T0 as well as T1 (the same rule applies to L2VPN). However, L2VPN is limited (server or client) to one service per gateway, therefore it's not possible to utilize five L2VPN tunnels from the same T0 and we have to deploy five T1s.

NEW QUESTION # 28
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. Configure switch ports that connect to ESXi host manually as trunk ports.
- B. Configure redundant physical switches to enhance availability.
- C. Use only IPv4 addressing in all deployments.
- D. Modify the Spanning Tree Protocol to increase the time to transition to the forwarding state.
- E. Configure switch ports with a Dynamic Trunking Protocol.
Answer: A,B
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).
