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.

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. Reference: Click here

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 Reference: Click here

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”

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:

802.11r Fast Transition (FT) Roaming is an amendment to the 802.11 IEEE standards. It is a new concept for roaming. The initial handshake with the new AP occurs before client roams to the target AP. Therefor it is called Fast Transition. 802.11rprovides two methods of roaming:Over-the-air: With this type of roaming, the client communicates directly with the target AP using IEEE 802.11authentication with the Fast Transition (FT) authentication algorithm.Over-the-DS (distribution system): With this type of roaming, the client communicates  with the target AP through the current AP. The communication between the client and the target AP is carried in FT action frames between the client and the current AP and is then sent through the controller.But both of these methods do not deal with legacy clients. The 802.11k allows 11k capable clients to request a neighbor report containing information about known neighbor APs that are candidates for roaming. Click hereClick here IEEE 802.11v is an amendment to the IEEE 802.11 standard which describes numerous enhancements to wireless network management. One such enhancement is Network assisted Power Savings which helps clients to improve the battery life by enabling them to sleep longer. Another enhancement is Network assisted Roaming which enables the WLAN to send requests to associated clients, advising the clients as to better APs to associate to. This is useful for both load balancing and in directing poorly connected clients. Click hereClick here Cisco 802.11r supports three modes:Pure mode: only allows 802.11r client to connectMixed mode: allows both clients that do and do not support FT to connect Adaptive mode: does not advertise the FT AKM at all, but will use FT when supported clients connect Therefore “Adaptive mode” is the best answer here.

The words “try” and “except” are Python keywords and are used to catch exceptions. For example:try:print 1/0 except ZeroDivisionError:print ‘Error! We cannot divide by zero!!!’
