Sometimes called Advanced Routing concepts, the Cisco Enterprise Networking, Security, and Automation covers the following topics.

What is special about OSPF area 0?
What is the function of HSRP?
What would happen if there is no router ID in OSPF config?
What is STP?
How do you redistribute OSPF in EIGRP?
What NAT?
What is the advantage of NAT?
What are the disadvantages of NAT?
What is Dynamic NAT?
What is NAT Overload (aka PAT)?
How do you configure EIGRP summarization?
What is the difference between numbered ACL and named ACL? Any feature differences?
What is the function of virtual IP in HSRP group?
In EIGRP can you use multiple EIGRP as numbers in different routers?
How do you propagate default route into EIGRP area?
If a router has a ACL configured on an interface, what will happen to the packets that doesn’t match the ACLs?
What is the function of ABR?
If you have extended ACL and applly this closest to the destination, what is the negative impact?
If the overload keyword is not attached to the PAT, what will happen?
What are ARBs?
How would packets behave on routers with multiple ACLs?
How do you set a router to an ABR?
How do you summarize OSPF routes?
Where is the best place to apply Standard ACL?
Where is the best place to apply Extended ACL?
How to do enable EIGRP on a router?
What parameters needed for the EIGRP to form neighbours?
If you have NAT already working on the NAT table, what is the inside global address?
When you redistribute EIGRP into OSPF, what will happen if the command is missing subnets?
How do you configure Dynamic NAT?
How would the stand-by neighbour know it is time to take over? (HSRP failover)
How do you enable EIGRP on multiple interfaces (or all interfaces) so that router attached to the networks?
What is the Access List used for NAT configuration? What is the function of the Access list used for your NAT configuration?
Where did you do the redistribution on your project? What is the function of the redistribution?
What is the function of the default route?
Why is the order of the ACL statements matters?
How do you configure router in OSPF Area 10?
What is the advantage of using Extended ACL over Standard ACL?
If you have a NAT pool configured and 10 IP addresses in the pool. This is dynamic NAT. If 20 people try to access the Internet simultaneously, what would happen?
If an OSPF interface is configured as passive, what will happen to the OSPF neighbours on the link connected to this interface? What would be the result of this?
How do you make an HSRP router the active router?
What is the function of wildcard mask when you configure OSPF network?
How does the wireless recieve IP address from DHCP server, when DHCP server is in the datacenter?
