Which THREE are valid methods to isolate and secure management traffic on a vSphere Distributed Switch? (Choose three.)

A company runs a three-tier application on vSphere 7.0. The web tier uses VLAN 100, app tier VLAN 200, and database tier VLAN 300. Each tier is on a separate port group on a vSphere distributed switch. The environment uses Network I/O Control (NIOC) with shares set to: Web (50), App (30), Database (20). The physical uplinks are two 10 GbE NICs in a team. Recently, the database team reports slow performance during peak hours. The network team checks the physical switches and finds no congestion. The ESXi host shows the two uplinks are heavily utilized with many dropped packets on the database port group. The administrator suspects that the database traffic is being starved by other traffic. Which action should the administrator take to resolve the issue? A. Increase the number of physical uplinks to four 10 GbE NICs. B. Change the NIOC shares to Web (10), App (30), Database (60). C. Create a separate vSphere standard switch for the database tier. D. Enable SR-IOV on the physical NICs and assign virtual functions to database VMs.
