You are designing an EVPN/VXLAN overlay network for your data center. You are planning on reusing some of your existing devices that do not support VXLAN routing.

Which gateway model should be deployed to support this architecture?

A. spine gateway

B. leaf gateway

C. server based gateway

D. underlay gateway

You are asked to design a DCI that offers policy control, active/active multihoming with load balancing, and minimizes flooding of BUM traffic.

Which DCI implementation satisfies these requirements?

A. EVPN

B. circuit cross-connect

C. BGP Layer 2 VPN

D. VPLS LAG

Your company is deploying a private cloud based on OpenStack and has selected Contrail Networking as their SDN controller. The data center supporting this private cloud will use an IP fabric architecture consisting of QFX Series switches and MX Series routers.

Which two statements are true in this scenario? (Choose two.)

A. All vRouters maintain identical forwarding tables for all virtual networks.

B. SDN Gateway devices may contain per-tenant MAC and IP addresses.

C. Each vRouter maintains separate forwarding tables for various virtual networks.

D. Spine and leaf devices may contain per-tenant MAC and IP addresses.

When considering environmental conditions in a data center, which two statements are correct? (Choose two.)

A. The device air intake should face the cold aisle.

B. Relative humidity that is too low can cause water condensation.

C. Device exhaust fans should face the cold aisle.

D. The temperature should be measured at multiple heights.

Which two Junos components does cRPD contain? (Choose two.)

A. Kubernetes

B. RIB

C. Kernel

D. MGD

You are designing a Layer 3 Clos fabric architecture for a new data center network infrastructure. You use IBGP for the underlay control plane of the fabric.

Which devices must support BGP route reflection and BGP ADD-PATH?

A. spine nodes

B. leaf nodes

C. fabric interconnect routers

D. fabric perimeter routers

You are designing a data center where all your servers in each rack will be connected to two top-of-rack (ToR) switches using Layer 2, as shown in the exhibit. You must implement a high availability solution that maintains link layer connectivity to each server when one of the ToR switches fails.

In this scenario, which solution will accomplish this task?

A. Virtual Chassis with LAG

B. chassis cluster with LAG

C. non-stop bridging (NSB)

D. bidirectional forwarding detection (BFD)

What are two considerations when designing an IP fabric? (Choose two.)

A. Every leaf node should have an uplink to every spine node.

B. Leaf nodes and spine nodes should be the same type of device.

C. Uplinks from servers to the leaf nodes should be 40GbE links.

D. All spine nodes should be the same type of device.

When using VPLS for a Data Center Interconnect, which statement about MAC learning is correct?

A. MAC learning is not used.

B. Management plane MAC learning is used.

C. Control plane MAC learning is used.

D. Data plane MAC learning is used.
