Question No : 1
You are implementing perimeter security for your data center. You need to inspect all traffic at Layer 7 and ensure the failure of a port or device will not result in an interruption to traffic flows.
In this scenario, which design would satisfy these requirements?

正解:

Question No : 2
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.



In this scenario, which two statements are true? (Choose two.)

正解:

Question No : 3
You are designing an EBGP IP fabric for a multi-site data center. In this scenario, which two statements are true? (Choose two.)

正解:

Question No : 4
Referring to the exhibit, DC1 and DC2 have a DCI across a service provider WAN connection. Host1 in DC1 must have Layer 2 connectivity to host2 in DC2. A VXLAN tunnel must be created between VTEP1 and VTEP2.



In this scenario, which statement is true?

正解:

Question No : 5
After configuring an IP fabric using EBGP as your routing protocol, you notice that not all of the routes are showing up in the routing tables. You have verified that all adjacencies have formed, and that all policies are in place and configured properly.
In this scenario, which statement is true?

正解:

Question No : 6
A company wants to expand their hosting business and is seeking solutions to support multiple tenants. Each tenant should be able to configure their own logical interfaces. Also, based on customer needs, all routing features must be supported.
What will satisfy the customer’s requirements?

正解:

Question No : 7
Which two statements describe MAC address learning for VPLS and EVPN? (Choose two.)

正解:

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?

正解:

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?

正解:

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.)

正解:

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?

正解:

Question No : 12
You work in a data center where VMs and hosts are frequently moved. Your design needs to eliminate inefficient traffic flows.
In this scenario, which two solutions will satisfy this requirement? (Choose two.)

正解:

Question No : 13
Which statement is true about a Data Center Interconnect over an IP network?

正解:

Question No : 14
You are configuring VXLAN, and you must ensure that all switches for the multicast groups advertise their existence and learn about other VTEPs.
In this scenario, which protocol will accomplish this task?

正解:

Question No : 15
You are designing a Layer 3 fabric underlay using EBGP. You will implement an EVPN-signaled VXLAN overlay on the Layer 3 fabric.
In this scenario, what must you do in the underlay to ensure that the VXLAN overlay will be able to function properly?

正解:
