Question 6 of 65
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?
Answer

Suggested Answer

The suggested answer is B.

Question 7 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?
Answer

Suggested Answer

The suggested answer is 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 8 of 65
Which statement is true about a Data Center Interconnect over an IP network?
Answer

Suggested Answer

The suggested answer is 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 9 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.)
Answer

Suggested Answer

The suggested answer is 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.
