What eliminates switching loops?

A network administrator is configuring a switch when an error message appears. The configuration commands and error message appear as follows:
Switch(config)# interface fastethernet 0/1
Switch(config-if)# switchport mode trunk
Command rejected: An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode.
What is the problem?

Given the IP address and subnet mask of 172.16.134.56 255.255.255.224, on which subnetwork does this address reside?

The ISP of the XYZ Company is moving to IPv6 but XYZ wants to continue to use only IPv4 for another year.
Which IPv4-to-IPv6 transition method would allow the company to continue using only IPv4 addresses?

Consider this router output:
Router# confug
Translating "confug"...domain server (255.255.255.255)
Translating "confug"...domain server (255.255.255.255)
(255.255.255.255)% Unknown command or computer name, or unable to find computer address
What command could help with this situation?

After several configuration changes are made to a router, the copy running-configuration startup-configuration command is issued. Where will the changes be stored?

What is associated with link-state routing protocols?

A router has learned about network 192.168.168.0 through static and dynamic routing processes. Which route will appear in the routing table for this network if the router has learned multiple routes?

What is one reason to use the ip ospf priority command when the OSPF routing protocol is in use?

Which router command will verify that the router has a path to a destination network?
