An EVPN-signaled VXLAN overlay has been deployed in the network shown in the exhibit. Host1 is a bare metal server, and is dual-homed to the network. The IP addresses 10.1.1.1/24 and 10.1.1.2/24 are assigned to the same physical NIC, and no virtualization is configured on the server.

Question No : 8

You are configuring an EVPN overlay network. You want to ensure that leaf devices can respond to ARP requests from locally connected hosts, when the leaf device knows the MAC of the intended destination.
In this scenario, what should you configure on the leaf devices to accomplish this task?

Question No : 9

You host a multitenant data center that runs VMware. You must perform deep packet inspection on all inter-tenant traffic that is flowing between the VMs within the same hypervisor. Your solution must provide the security services without needing to leave the physical device.
In this scenario, what should you do to solve this problem?

A.Use separate vSwitches to isolate each tenant's networks and use IP tables to evaluate inter-tenant traffic.
B.Use VLANs to isolate each tenant's networks and use an SRX Series device to evaluate inter-tenant traffic.
C.Use a vMX device to isolate each tenant's networks and use with firewall filters to evaluate inter-tenant traffic.
D.Use separate vSwitches to isolate each tenant's networks and use a vSRX Series device to evaluate inter-tenant traffic.

정답:

Question No : 10

A client with five data centers spread around the country uses MPLS L2VPNs to provide point-to-point data center Interconnects between each data center in a full-mesh network. The client is considering an MPLS EVPN implementation.
In this scenario, what are three advantages of using MPLS EVPN interconnects? (Choose three.)

A.They provide for static configuration that does not require a Dynamic Routing Protocol.
B.They provide for lower transmission latency.
C.They provide for a local proxy ARP/ND resolution.
D.They provide for point-to-multipoint connectivity.
E.They provide for MAC learning in the control plane.

정답:

Question No : 11

A VXLAN adds 50 to 54 bytes of extra header information to an Ethernet frame.
In this scenario, how would you accommodate this increase?
