Answer: D
Q2. -- Exhibit --An NSX administrator has deployed the network shown in the Exhibit. Based on the exhibit, which statement describes a valid method for redirecting traffic around the fault?
A. Building this topology using a layer 2 switched fabric with connectivity between the leafs would allow traffic to be redirected around the fault to another leaf.
B. Building this topology using a layer 3 routed fabric with connectivity between the leafs would allow traffic to be redirected around the fault to another leaf.
C. Building this topology using a layer 2 switched fabric with spanning tree will provide the quickest path around the fault to another spine when connectivity is lost.
D. Building this topology using a layer 3 routed fabric will provide the quickest path around the fault to another spine when connectivity is lost.
Answer: D
Q3. Based on VMware's best practices, what two statements define the best solution for scaling layer 2 services for the virtual network? (Choose two.)
A. Employ a layer 2 switched network.
B. Employ a layer 3 switched network.
C. Use GRE for an overlay network.
D. Use VXLAN for an overlay network.
Answer: B, D
Q4. Which three network policy settings can only be configured on a vSphere 5.5 Distributed Switch? (Choose three.)
A. Access Control Lists (ACLs)
B. Network I/O Control
C. LACP v2
D. NetFlow
E. DSCP Marking
Answer: A, C, E
Q5. Which statement is true regarding deploying NSX over a physical network?
A. OSPF can be used for Management traffic in a Layer 3 fabric design.
B. NSX can implement IPv6 on an IPv4 physical network.
C. Routing is supported on bridged interfaces.
D. VLANs are not required to separate traffic between virtual machines.
Answer: B
Q6. Which two characteristics of the underlying physical network does VMware NSX require for robust IP transport? (Choose two.)
A. The physical network should provide scalable network I/O using Layer 2 Multipathing (L2MP) and Multichassis Link Aggregation (MLAG).
B. The physical network should provide scalable network I/O using Equal Cost Multipathing (ECMP).
C. QoS is not necessary since classification and marking will be done in the overlay.
D. QoS classification and marking is required to provide end-to-end flow control.
Answer: B, D
Q7. What is the minimum MTU size recommended by VMware for the physical network when deploying NSX for vSphere?
A. 1550
B. 1600
C. 2148
D. 9000
Answer: B
Q8. What are three switch features found only on vSphere Distributed Switches? (Choose three.)
A. Network I/O Control
B. CDP
C. LLDP
D. SR-IOV
E. Port Mirroring
Answer: A, C, E
Q9. An administrator wishes to control traffic flow between two virtual machines. The virtual machines are in the same subnet, but are located on separate ESXi hosts. The administrator deploys an Edge Firewall to one of the hosts and verifies the default firewall rule is set to deny, but the two virtual machines can still communicate with each other. What task will correct this issue?
A. Configure both ESXi host firewalls to deny traffic from the virtual machine on the other host.
B. Deploy another Edge Firewall on the host running the second virtual machine.
C. Remove any other firewall appliances that may exist on either of the ESXi hosts.
D. Deploy a Distributed Firewall with firewall rules to prevent traffic between the virtual machines.
Answer: D
Q10. What is a prerequisite to deploying a Logical Switch?
A. Configure the VXLAN Tunnel Endpoint's (VTEP) VLAN on the trunk in the physical switches.
B. Add the ESXi hosts to the same vSphere Distributed Switch.
C. Prepare and configure VTEPs on the ESXi hosts using the vSphere Web Client.
D. Create a port group on the vSphere Distributed Switch.
Answer: A
