56. During a vSAN design workshop, the infrastructure team highlighted the need to ensure the availability and resiliency of the vSAN network for their production clusters. Each ESXi host is connected to the TOR switches with two 1 GB physical adapters. The physical network fabric is using a spine-leaf architecture.

These subnets are available for the ESXi hosts:

• Subnet A: 192.168.10.0/24
• Subnet B: 192.168.20.0/24

Which three strategies can the architect suggest to satisfy these customer requirements? (Choose three.)

• A. Configure MTU 9K jumbo frame on the hosts and leaf switches.
• B. Configure NIC teaming.
• C. Replace the server NICs with 10 GB ones.
• D. Add one vSAN VMKernel port to subnet B.
• E. Add one vSAN VMKernel port to subnet A.
• F. Add two vSAN VMKernel ports to subnet A.

Notes: ABC or ABE

E. Add one vSAN VMKernel Port to Subnet A: Adding a vSAN VMKernel port to Subnet A will provide a dedicated network path for vSAN traffic on this subnet. This separation of traffic can help in managing and optimizing network flows, improving performance, and ensuring better availability. It’s important to balance the vSAN traffic across the available subnets and physical NICs to avoid network congestion and ensure redundancy.

The other options, while potentially beneficial in certain contexts, might not be as directly impactful or feasible given the scenario:

C. Replace the Server NICs with 10 GB Ones: While upgrading to 10 GB NICs can provide a significant boost in network performance, this may involve additional cost and hardware changes. It’s a valid long-term strategy but might not be immediately implementable.

56. 在vSAN设计研讨会期间，基础设施团队强调需要确保生产集群的vSAN网络的可用性和弹性。每个ESXi主机通过两个1 GB的物理适配器连接到TOR交换机。物理网络架构采用了脊柱-叶子结构。

以下子网可供ESXi主机使用：

• 子网A：192.168.10.0/24

• 子网B：192.168.20.0/24

架构师可以提出哪三种策略来满足客户的需求？（选择三个。）

• A. 在主机和叶子交换机上配置MTU 9K巨帧。
• B. 配置NIC绑定。
• C. 将服务器NIC替换为10 GB的。D. 在子网B上添加一个vSAN VMKernel端口。
• E. 在子网A上添加一个vSAN VMKernel端口。
• F. 在子网A上添加两个vSAN VMKernel端口。

注释：ABC或者ABE

E. 在子网A上添加一个vSAN VMKernel端口：在子网A上添加一个vSAN VMKernel端口将为该子网上的vSAN流量提供专用的网络路径。这种流量的分离有助于管理和优化网络流，提高性能，并确保更好的可用性。重要的是要平衡可用子网和物理NIC上的vSAN流量，以避免网络拥塞并确保冗余。

其他选项虽然在某些情况下可能有益，但鉴于这一场景，可能不会那么直接有影响或可行：

C. 将服务器NIC替换为10 GB的：虽然升级到10 GB NIC可以显著提高网络性能，但这可能涉及额外的成本和硬件更改。这是一个有效的长期策略，但可能无法立即实施。
