Flash cards

I am going to create flash cards for my CCIE lab studys. A sample question could look like this:

Question:

Routers R1 and R2 are EIGRP neighbors. 155.1.48.0/24 is the transit link between them.
R1 also has a loopback with the IP-address 150.1.1.1/24. The default settings are
enabled for EIGRP and the correct network statements are in place. What netmask will R2
have for R1’s loopback?

Answer:

The netmask is 255.255.0.0 or /16 since auto-summary is on by default.

I am going to create the flashcards in Anki, if there is interest I will make it publically available for download and it will be updated whenever I add content to it.
