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.

Network Fundamentals covers 20% of the exam/ Pearson VUE is the authorized test delivery partner

Which interface port type will be reported by the show spanning-tree vlan 1 command if your two interconnected switches are both running rapid PVST?

P2p

What are characteristics that are specific to UDP?

Packet delivery is not guaranteed/ Stands for User Datagram Protocol/ Packets are treated independently

The OSI and TCP/IP models provide a visual networking reference. Which layers of the OSI Reference Model map to the link layer of the TCP/IP stack? (Choose two.)

Physical/ Data Link

At what layer do the TCP and UDP protocols work within the TCP model?

Transport layer

What statements best describe TCP? Choose all options that best answer the question.

Upon receipt of a TCP packet, the receiver returns an acknowledgment to the sender/ TCP header requires a source and destination port/ Is a connection-orientated protcol

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

Match the protocol or service to the correct Internet Protocol traffic type.

TCP (FTP, HTTP, Telnet) UDP(VOIP, DNS, DHCP)

Identify the message an initiating device sends in the TCP connection setup.

send SYN
