CCNA-2

What are two characteristics of a controller-based network? (Choose two)

• The administrator can make configuration updates from the CLI.

• It uses northbound and southbound APIs to communicate between architectural layers.

• It moves the control plane to a central point.

• It decentralizes the control plane, which allows each device to make its own forwarding decisions.

• It uses Telnet to report system issues

Which attribute does a router use to select the best path when two or more different routes to the same destination exist from two different routing protocols?

• dual algorithm

• metric

• administrative distance

• hop count

Refer to Exhibit. How does SW2 interact with other switches in this VTP domain?

• It processes VTP updates from any VTP clients on the network on its access ports.

• It receives updates from all VTP servers and forwards all locally configured VLANs out all trunk ports.

• It forwards only the VTP advertisements that it receives on its trunk ports.

• It transmits and processes VTP updates from any VTP Clients on the network on its trunk ports.

Which unified access point mode continues to serve wireless clients after losing connectivity to the Cisco Wireless LAN Controller?

• sniffer

• mesh

• flexconnect

• local

Which two encoding methods are supported by REST APIs? (Choose two)

• YAML

• JSON

• EBCDIC

• SGML

• XML

What are two reasons that cause late collisions to increment on an Ethernet interface? (Choose two)

• when the sending device waits 15 seconds before sending the frame again

• when the cable length limits are exceeded

• when one side of the connection is configured for half-duplex

• when Carriner Sense Multiple Access/Collision Detection is used

• when a collision occurs after the 32nd byte of a frame has been transmitted

Router A learns the same route from two different neighbors, one of the neighbor routers is an OSPF neighbor and the other is an EIGRP neighbor. What is the administrative distance of the route that will be installed in the routing table?

• 20

• 90

• 110

• 115

What is the primary effect of the spanning-tree portfast command?

• It enables BPDU messages

• It minimizes spanning-tree convergence time

• It immediately puts the port into the forwarding state when the switch is reloaded

• It immediately enables the port in the listening state

What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?

• The Layer 2 switch drops the received frame.

• The Layer 2 switch floods packets to all ports except the receiving port in the given VLAN.

• The Layer 2 switch sends a copy of a packet to CPU for destination MAC address learning.

• The Layer 2 switch forwards the packet and adds the destination MAC address to its MAC address table.

Refer to the exhibit. Which route does R1 select for traffic that is destined to 192 168.16.2?

• 192.168.16.0/21

• 192.168.16.0/24

• 192.168 26.0/26

• 192.168.16.0/27
