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.)
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.)
In a data center environment where VMs and hosts are frequently moved, technologies that provide efficient traffic management and minimize unnecessary data paths are crucial. VXLAN (Virtual Extensible LAN) helps in creating a scalable network architecture, enabling layer 2 segments to span multiple locations over a layer 3 network. EVPN (Ethernet VPN) provides advanced control over the VXLAN gateway for improved routing efficiency and mobility. Together, VXLAN and EVPN enable efficient traffic flows and seamless VM mobility, making them a suitable solution for the scenario described.
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.)
MPLS EVPN interconnects provide several advantages. They allow for local proxy ARP/ND resolution, which can reduce the amount of broadcast traffic and improve performance and security. They enable point-to-multipoint connectivity, facilitating multipoint connections and enhancing network scalability and efficiency. They support MAC learning in the control plane, which offers better scaling and security by preventing flooding of unknown unicast traffic.
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?
In an EVPN overlay network, configuring proxy ARP on leaf devices ensures that they can respond to ARP requests from locally connected hosts when the leaf device knows the MAC address of the intended destination. Proxy ARP allows the leaf device to reply on behalf of the device it knows, thereby facilitating efficient communication within the network. Static ARP entries, persistent MAC learning, and IGMP snooping do not address this specific requirement.
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?
To support multiple tenants, where each tenant can configure their own logical interfaces and require all routing features, logical systems are the appropriate solution. Logical systems allow for the segregation of the network into multiple independent systems, each capable of its own routing, policies, and configurations. This aligns with the need for tenant isolation and the comprehensive routing capabilities required by the customer.
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?
In an IP fabric using EBGP, if all the adjacencies have formed and policies are correctly configured, but not all routes are appearing in the routing tables, it is likely that the routers have not been configured with the multipath multiple-as parameter. The multipath multiple-as parameter enables the router to install multiple paths from different autonomous systems into the routing table, which is necessary for proper route visibility and load balancing in an EBGP environment.
