Are these topics in the CCNA ? (Subnetting)
-
Hey.
I would like to know if these topics are included in the CCNA exam:- Wildcard mask
- Supernetting
- IP arregation
- IP summarization
Thanks in advance.

The current iteration of the CCNA 200-301 exam includes the following:
- 1.6 Configure and verify IPv4 addressing and subnetting
- 1.7 Describe the need for private IPv4 addressing
Having said that, notice that these are broad topics and the broadest of topics in this would be in the realm of subnetting. So in that realm includes the contexts of the topics you mentioned...but no in the wording you mention. Never in Cisco terms do we use "supernetting"; we tend to see "summarization" and "aggregation". Even then the context is not a full explanation but more of a scenario...for example. you try to configure 192.168.10.33 255.255.255.240 on interface g0/0...it is not allow you to do so. They show you a diagram with multiple interfaces but on g0/1, you see the ip address has already been configured 192.168.10.11 255.255.255.128 configured. In context of this router, your configuration on g0/0 is within the address range of the network found on g0/1. This is an example of where a smaller subnet is within a larger subnet.
Or you may look at a routing table with
show ip route
, you realize the subnet you configured for g0/2 doesn't appear in the routing table at all...has the address been aggregated together within a larger subnet but would show if we used something similar to the no summarization commands found in routing protocols.
