2V0-641 VMware Professional Network Virtualization Exam
Which feature is not supported by the vSphere 5.5 Distributed Switch?
Multiple link aggregation groups
Differentiated Service Code Point (DSCP) QOS at layer3
Packet captures at the uplink, virtual switch port, or vNIC
IGMP snooping at layer 2
Which statement describes the traffic throughput of the NSX Distributed Firewall?
By decoupling the firewall services from the virtualization layer, traffic is directed to the distribution layer for firewall processing within a service module.
By deploying firewall software on a per virtual machine basis, firewall services will be distributed across multiple compute nodes.
Firewall services are implemented as kernel modules and provide traffic filtering between the virtual machine's vNIC and the vSwitch.
Firewall services are distributed as a software firewall appliance and may be deployed on more than one ESXi host for scalability and high availability
Which two statements describe the network connectivity provided by a vSphere Standard Switch (vSS)? (Choose two.)
A vSS provides a direct and logical connection between a virtual machine NIC and a physical NIC.
A vSS provides a direct and logical connection between two vSphere Distributed Switches
A vSS connects the vNIC of a virtual machine to the physical network based on the bandwidth of the VM's configured network adapter.
A vSS connects the vNIC of a virtual machine to the physical network and is not restricted to a specific bandwidth allocation based on the VM's configured network adapter.
Which statement is true regarding multicast traffic when implementing NSX?
A multicast address range is required when using vCenter Server 5.5
A multicast address range is required when using ESXi 5.1 hosts
A multicast address range is required when using ESXi 5.0 hosts
A multicast address range is required when using vCenter Server 5.1
Where are the Logical Firewall logs saved?
On the vNIC-FW module
On the ESXi host
On the NSX Controllers
On the NSX Manager
Which statement best describes firewall packet processing in an NSX environment?
Packets that require firewall processing are redirected to the nearest ESXi host deployed with a virtual machine based firewall.
Packets that require firewall processing are forwarded to a physical firewall appliance.
Packets that require firewall processing are processed in-line on the local hypervisor.
Packets that require firewall processing are forwarded to the nearest ESXi host with an embedded firewall module.
