Explanation
Clustering lets you group multiple Firepower Threat Defense (FTD) units together as a single logical device.
Clustering is only supported for the FTD device on the Firepower 9300 and the Firepower 4100 series. A cluster provides all the convenience of a single device (management, integration into a network) while achieving the increased throughput and redundancy of multiple devices.}

HSRP consists of 6 states:

Please notice that not all routers in a HSRP group go through all states above. In a HSRP group, only one router reaches active state and one router reaches standby state. Other routers will stop at listen state.

Explanation
Marking = applied on traffic to convey Information to a downstream device Classification = distinguish traffic types Trust = Permits traffic to pass through the device while retaining DSCP/COS values shapping = process used to buffer traffic that exceeds a predefined rate.

Explanation
With BGP, we must advertise the correct network and subnet mask in the “network” command (in this case network 10.1.1.0/24 on R1 and network 10.2.2.0/24 on R2). BGP is very strict in the routing advertisements. In other words, BGP only advertises the network which exists exactly in the routing table. In this case, if you put the command “network x.x.0.0 mask 255.255.0.0” or
“network x.0.0.0 mask 255.0.0.0” or “network x.x.x.x mask 255.255.255.255” then BGP will not advertise anything.
It is easy to establish eBGP neighborship via the direct link. But let’s see what are required when we want to establish eBGP neighborship via their loopback interfaces. We will need two commands:
+ the command “neighbor 10.1.1.1 ebgp-multihop 2” on R1 and “neighbor 10.2.2.2 ebgpmultihop
2″ on R1. This command increases the TTL value to 2 so that BGP updates can reach the BGP neighbor which is two hops away.
+ Answer ‘R1 (config) #router bgp 1
R1 (config-router) #neighbor 192.168.10.2 remote-as 2
R1 (config-router) #network 10.1.1.0 mask 255.255.255.0
R2 (config) #router bgp 2
R2 (config-router) #neighbor 192.168.10.1 remote-as 1
R2 (config-router) #network 10.2.2.0 mask 255.255.255.0
Quick Wireless Summary
Cisco Access Points (APs) can operate in one of two modes: autonomous or lightweight
+ Autonomous: self-sufficient and standalone. Used for small wireless networks.
+ Lightweight: A Cisco lightweight AP (LAP) has to join a Wireless LAN Controller (WLC) to function.
LAP and WLC communicate with each other via a logical pair of CAPWAP tunnels.
– Control and Provisioning for Wireless Access Point (CAPWAP) is an IETF standard for control messaging for setup, authentication and operations between APs and WLCs. CAPWAP is similar to LWAPP except the following differences:
+CAPWAP uses Datagram Transport Layer Security (DTLS) for authentication and encryption to protect traffic between APs and controllers. LWAPP uses AES.
+ CAPWAP has a dynamic maximum transmission unit (MTU) discovery mechanism.
+ CAPWAP runs on UDP ports 5246 (control messages) and 5247 (data messages) An LAP operates in one of six different modes:
+ Local mode (default mode): measures noise floor and interference, and scans for intrusion detection (IDS) events every 180 seconds on unused channels
+ FlexConnect, formerly known as Hybrid Remote Edge AP (H-REAP), mode: allows data traffic to be switched locally and not go back to the controller. The FlexConnect AP can perform standalone client authentication and switch VLAN traffic locally even when it’s disconnected to the WLC (Local Switched). FlexConnect AP can also tunnel (via CAPWAP) both user wireless data and control traffic to a centralized WLC (Central Switched).
+ Monitor mode: does not handle data traffic between clients and the infrastructure. It acts like a sensor for location-based services (LBS), rogue AP detection, and IDS
+ Rogue detector mode: monitor for rogue APs. It does not handle data at all.
+ Sniffer mode: run as a sniffer and captures and forwards all the packets on a particular channel to a remote machine where you can use protocol analysis tool (Wireshark, Airopeek, etc) to review the packets and diagnose issues. Strictly used for troubleshooting purposes.
+ Bridge mode: bridge together the WLAN and the wired infrastructure together.
Mobility Express is the ability to use an access point (AP) as a controller instead of a real WLAN controller. But this solution is only suitable for small to midsize, or multi-site branch locations where you might not want to invest in a dedicated WLC. A Mobility Express WLC can support up to 100 Aps

Traffic Policing: Drops excessive Traffic, causes TCP retransmissions, introduce no delay/jitter Shaping: buffers, excessive traffic, introduce delay and jitter, typically delays, rather than drops traffic

Explanation
Although the statement “permit tcp any any gt … lt …” seems to be correct but in fact it is not.
Each ACL statement only supports either “gt” or “lt” but not both:

In fact answer ‘Permit tcp any any range 22 443
Deny tcp any any eq 80
eq 80.

Explanation
There are two types of hypervisors: type 1 and type 2 hypervisor.
In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server. Then instances of an operating system (OS) are installed on the hypervisor. Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V.
In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. answer ‘Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS’ big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows).

From the second command output (show spanning-tree mst) we learn that MST1 includes VLANs 10 & 20.Therefore if we want DSW1 to become root bridge for these VLANs we need to set the MST 1 region to root ->The command “spanning-tree mst 1 root primary” can do the trick. In fact, this command runs a macro and setsthe priority lower than the current root.
Also we can see the current root bridge for these VLANs has the priority of 32769 (default value + sysid) so wecan set the priority of DSW1 to a specific lower value. But notice that the priority must be a multiple of 4096.
