Which device's primary purpose is to divide the network into trusted and untrusted areas?

Firewall

What type of device establishes a barrier between a trusted, secure internal networking and another outside network?

Firewalls

Which statements best describe a Cisco 3800 Series router?

It is equipped with dual power supplies/ It contains four network modules

Which STP port states are transitional and would be a cause for concern if seen repeatedly occurring on a switchport?

Learning/ Listening

Which component provide pathways in the network?

Media

You have typed in the command show spanning-tree on your Ethernet switch. Which output confirms that your current switch is acting as the STP root bridge?

The Root ID Priority matches the Bridge ID Priority/ The Root ID Address matches the Bridge ID Address/ The Root ID displays "This bridge is the root"

What architecture used by many small and medium-sized networks eliminates the traditional top tier entriely?

Collapsed Core

Match the networking services with the correct networking architecture tier.

Distribution(Apply filtering and routing policies)/ Care(Provide high speed backbone networking)/ Access(Apply network access policies)

Select the options that describe the 200-301 CCNA certification exam.

What are features of the spine-leaf architecture?

Uses IS-IS, VXLAN overlays, and MP-BGP technologies/ Able to scale up without changing the underlying structure/ Very stable and deterministic with little latency

Which statements are true concerning the leaf and spine architecture?

Consists of two layers/ All leaf switches are connected to all spine switches

Which indicator lights are typically found on the front of a Cisco switch?

Speed/ Duplex

What are characteristics of the traditional architecture model?

Switch additions increase the distribution layer size/ Switch numbers are reduced with additions/ Scalability decreases over time with device reductions
