There are five basic device roles in the fabric overlay:
Control plane node: This node contains the settings, protocols, and mapping tables to provide the endpoint-to-location (EID-to-RLOC) mapping system for the fabric overlay. 
Fabric border node: This fabric device (for example, core layer device) connects external Layer 3 networks to the SDA fabric. 
Fabric edge node: This fabric device (for example, access or distribution layer device) connects wired endpoints to the SDA fabric. 
Fabric WLAN controller (WLC): This fabric device connects APs and wireless endpoints to the SDA fabric.
Intermediate nodes: These are intermediate routers or extended switches that do not provide any sort of SD-
Access fabric role other than underlay services. 

    

Lines (CON, AUX, VTY) default to level 1 privileges.

CEF uses a Forwarding Information Base (FIB) to make IP destination prefix-based switching decisions. The FIB is conceptually similar to a routing table or information base. It maintains a mirror image of the forwarding information contained in the IP routing table. When routing or topology changes occur in the network, the IP routing table is updated, and those changes are reflected in the FIB. The FIB maintains next-hop address information based on the information in the IP routing table. Because there is a one-to-one correlation between FIB entries and routing table entries, the FIB contains all known routes and eliminates the need for route cache maintenance that is associated with earlier switching paths such as fast switching and optimum switching. 
Note: In order to view the Routing information base (RIB) table, use the “show ip route” command.
To view the Forwarding Information Base (FIB), use the “show ip cef” command. RIB is in Control plane while FIB is in Data plane.

FlexConnect is a wireless solution for branch office and remote office deployments. It enables customers to configure and control access points in a branch or remote office from the corporate office through a wide area network (WAN) link without deploying a controller in each office. 
The FlexConnect access points can switch client data traffic locally and perform client authentication locally when their connection to the controller is lost. When they are connected to the controller, they can also send traffic back to the controller. In the connected mode, the FlexConnect access point can also perform local authentication.

The following different OSPF types are compatible with each other:
Broadcast and Non-Broadcast (adjust hello/dead timers) 
Point-to-Point and Point-to-Multipoint (adjust hello/dead timers) 
Broadcast and Non-Broadcast networks elect DR/BDR so they are compatible. Point-topoint/ multipoint do not elect DR/BDR so they are compatible. 

Firepower Threat Defense (FTD) provides six interface modes which are: Routed, Switched, Inline Pair, Inline Pair with Tap, Passive, Passive (ERSPAN). 
When Inline Pair Mode is in use, packets can be blocked since they are processed inline When you use Inline Pair mode, the packet goes mainly through the FTD Snort engine When Tap Mode is enabled, a copy of the packet is inspected and dropped internally while the actual traffic goes through FTD unmodified 

Answer ‘Route targets allow customers to be assigned overlapping addresses’ and answer ‘Route targets uniquely identify the customer routing table’ are not correct as only route distinguisher (RD) identifies the customer routing table and “allows customers to be assigned overlapping addresses”. 
Answer ‘When BGP is configured, route targets are transmitted as BGP standard communities’ is not correct as “When BGP is configured, route targets are transmitted as BGP extended communities”

The Cisco TrustSec solution simplifies the provisioning and management of network access control through the use of software-defined segmentation to classify network traffic and enforce policies for more flexible access controls. Traffic classification is based on endpoint identity, not IP address, enabling policy change without net-work redesign. 

This combination of commands is known as “Conditional debug” and will filter the debug output based on your conditions. Each condition added, will behave like an ‘And’ operator in Boolean logic. 
Some examples of the “debug ip ospf hello” are shown below:
