The protocol used to gather information about Cisco devices which share the same data link
What is CDP
What SNMP version uses community-based forms of security
What is Version 2
What is Syslog used for in network management?
Monitoring logs and generating event messages
In what type of memory is the Cisco IOS stored by default?
What is flash memory?
The Cisco IOS Software images and configuration files can be stored on
What is a central TFTP server
This protocol works with network devices, such as routers, switches, and wireless LAN access points across multiple manufacturers’ devices
What is LLDP
This SNMP version is supported by Cisco IOS software
What is Version 2 and 3
The command used to display logged messages on a Cisco device
show logging
What command displays the contents of flash memory?
show flash:
Command used to copy an IOS image to a router or switch from a TFTP server
copy tftp flash
The protocol you should enable if you want your Cisco devices to discover each other and non-Cisco devices.
What is LLDP (Link Layer Discovery Protocol)?
This SNMP version does not provide encrypted management messages
What is Version 2
The severity level number that corresponds to “Emergency” in Syslog
0
Which command is used to back up the running configuration to a TFTP server?

What would be a valid reason to disable CDP on WAN interfaces, especially those connecting to outside networks?
To prevent leaking internal topology to untrusted networks.
This SNMP version authenticates the source of management messages
What is Version 3
The command that configures a router to send logs to a Syslog server
logging <IP Address>
What does the confreg 0x2142 command do in ROMMON mode?
It sets the configuration register to 0x2142, causing the device to ignore the startup configuration during bootup. This is useful for password recovery procedures.
What command sets the IOS image to boot on the next startup?
boot system flash:<filename>
You’ve enabled LLDP globally, but it’s not working on a specific port. What’s a likely configuration issue?
LLDP isn't enabled on the interface. Use lldp transmit and lldp receive.
This SNMP version is used for interoperability and includes message integrity reporting
What is Version 3
Why would you store Syslog messages on a remote server instead of locally on a router or switch?
To preserve logs after device reboots and for centralized analysis.
How can a configuration be restored from a text file using Tera Term?
By selecting Send file from the File menu in Tera Term, choosing the configuration file, and opening it. Tera Term will transmit the file's contents to the device, applying them as commands in the CLI.
Command that verifies the integrity of an IOS image file
verify /md5 flash:<filename>
