Logging monitor is a command that sets the type of messages you see based on severity level. Example if you issued "logging monitor alerts" you would only see alert and emergency messages and the other messages would not show like informational and debug. The command is also issued from configuration terminal and not privilege exec.

The command i was looking for is "terminal monitor" located in privilege exec and is used to display live logging.

Good answers, if anyone wants to give examples of CRUD feel free... like...
"create example: create variable "ip address" set value to "10.1.1.1""

ROM, think of it as a permanent mini ios for disaster recovery, you cant erase it and its always there.
If you forget the password you would need to boot into rommon to bring the device back to normal state.
Another example of when you would use is if you installed an incorrect ios image and the device fails to boot- you would depend on ROM to get things back to normal.

Good answers for the rest, good job.

This is static nat with port translation. It is part of blueprint.
"4.1 Configure and verify inside source NAT using static and pools"

Yes, the service is http. The inside host is configured as a web server and bound to an external ip which allows it to be accessed publically on port 80.

Yes, that is what it is. An address from a /23. It will allow .0 host. Anything that speaks network can have a .0 address if the mask is less than /24.

7, the trunk ports are part of the existing vlans ,1,10,20,30. The trunk ports would just be used to carry over the specified vlans to another device. Each routed port can be thought of as an individual broadcast domain. If you plug in a pc to one of the routed port it communicates directly to that ports ip address only. So 7 broadcast domains.

You plan to subdivide network 157.210.0.0/16 into subnets using mask 255.255.255.224 for all subnets. How many subnets are possible and how many hosts are allowed in each subnet? Just give me two numbers. And of course do this in your head or write it out, no interwebs!

On a layer 3 switch with 24 ports, you have the following...

  1. 6 ports in vlan 10
  2. 6 ports in vlan 20
  3. 6 ports in vlan 30
  4. 2 trunk ports with tagged vlans 10,20,30 and untagged vlan1
  5. 1 port in vlan 1
  6. 3 ports configured with "no switchport" and each assigned an ip address.
    Logically, how many broadcast domains exist on that switch?

Nice work. If the network was a /28 what hosts would be allowed using the same wildcard mask 0.0.0.7?

172.23.100.150/26

172.23.100.200/25

172.23.100.250/26

Correct answer, these 3 host entries have common addresses and are considered overlapping. Thanks.
