Question #11 (Topic: Topic 1)
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.)
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.
Answer: CDE
Question #12 (Topic: Topic 1)
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?
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.
Answer: D
Question #13 (Topic: Topic 1)
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?
device knows the MAC of the intended destination.
In this scenario, what should you configure on the leaf devices to accomplish this task?
A. proxy ARP
B. static ARP entries
C. persistent MAC learning
D. IGMP snooping
Answer: A
Question #14 (Topic: Topic 1)
Which two statements describe MAC address learning for VPLS and EVPN? (Choose two.)
A. EVPN learns MAC addresses in the data plane.
B. VPLS learns MAC addresses in the control plane.
C. VPLS learns MAC addresses in the data plane.
D. EVPN learns MAC addresses in the control plane.
Answer: CD
Question #15 (Topic: Topic 1)
