- B . monitor traffic
- C . show ethernet-switching table
- D . show interfaces
What does the “qualified-next-hop” feature do when configuring a static route?
- A . It allows you to specify an independent route preference value for an additional next hop.
- B . It specifies the IP address of the directly connected device.
- C . It instructs the device to verify the next-hop is reachable before activating the route.

What is the main advantage of using MACsec?
- A . It increases the speed of the network.
- B . It provides Layer 2 encryption for data confidentiality and integrity.
- C . It creates multiple virtual networks over a single physical infrastructure.

In a Spine/Leaf IP-Fabric architecture, what is the primary role of the leaf switches?
- A . To provide direct connectivity to servers.
- B . To interconnect different data centers.
- C . To perform deep packet inspection.
- D . To manage the overall data center network.
What is an advantage of using BFD?
- A . BFD is so lightweight that each protocol will generate its own unique BFD session by default, to replace its own hello messages.
- B . BFD built to handle the routing table of the entire Internet, and can safely redistribute it into OSPF.
- C . One BFD monitoring session can be used by multiple protocols.
- D . BFD is built to handle the routing table of the entire Internet, unlike IGPS.

- B . They are commonly referred to as interconnected data centers
- C . There is a maximum of three hops between any end-devices
- D . They are typically deployed in small to medium data centers
