Question six is correct. Look closely at the IP addresses, there is a class A 10.90.20.0 address with a prefix of /24. The default subnet mask for class A is /8. This means it’s discontiguous and unsupported by Ripv1.

Question six is correct, I made sure by creating this scenario in Packet Tracer, replicating the network statements with Ripv1, with failing pings. I then entered the command “version 2″, switching the protocol to Ripv2. This caused the network to converge, with successful LAN communication. I noticed the networks were discontiguous right away when I saw the subnet masks are different than the classful IP addresses in use. For instance, 10.20.40.0 is a class A address, which has a default subnet mask of /8 (255.0.0.0), but in the model it shows a subnet mask of /24 (255.255.255.0), which is a default subnet mask of class C. This is a Variable Length Subnet Mask when used in such a way. Please do more research before claiming answers are incorrect.

The question six is incorrect. ° The network statements are configured Incorrectly.

No, the loopback network address is 128, the IOS converts this address .129 to .128 because the difference is the last bit, this bit is the host area and will be set zero

Is Question 11′s answer a typo? “A connected route to the 10.16.1.128/27 network is added.” should it not be 10.16.1.12[9]
