When selecting a spine switch model, which two features are most important to ensure the switch can handle the required capacity and provide redundancy?

Support for stacking and virtual chassis technology

Advanced routing protocols and deep packet inspection

Low power consumption and compact form factor

High port density and support for the required port speed

In a Clos fabric, what is the primary role of spine switches?

To enforce access control lists (ACLs) and quality of service (QoS) policies at the fabric edge

To connect leaf switches to each other and to external networks

To forward traffic between leaf switches using equal-cost multipath (ECMP)

To provide the aggregation layer for inter-VLAN routing and security policies

Which two methods can be used to scale spine capacity in an existing Clos fabric?

Adding more spine switches or upgrading the speed of existing spine ports

Reducing the oversubscription ratio or increasing the leaf-to-spine ratio

Adding more leaf switches or increasing the number of servers per leaf

Enabling link aggregation on leaf uplinks or configuring QoS policies
