Question 6 of 65
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?
    Correct Answer: D

    Protocol Independent Multicast (PIM) is used to ensure that all switches for the multicast groups can advertise their existence and learn about other VTEPs in a VXLAN environment. PIM is designed to efficiently route multicast packets, making it the right protocol for managing multicast traffic in VXLAN.

Question 7 of 65
Which statement is true about a Data Center Interconnect over an IP network?
    Correct Answer: C

    Layer 2 data must be encapsulated when traversing an IP network because the IP network operates at Layer 3, which does not natively support Layer 2 frames. Encapsulation methods like VXLAN, GRE, or MPLS allow these Layer 2 frames to be transmitted over a Layer 3 IP network. This encapsulation is necessary to maintain the integrity and delivery of Layer 2 data between data centers.

Question 8 of 65
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.)
    Correct Answer: A, B

    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.

Question 9 of 65
A VXLAN adds 50 to 54 bytes of extra header information to an Ethernet frame.
In this scenario, how would you accommodate this increase?
    Correct Answer: B

Question 10 of 65
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.)
    Correct Answer: C, D, E

    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.
