IPsec failover fallsinto two categories:statelessfailover and stateful failover.Statelessfailover uses protocols such as the Hot Standby Router Protocol (HSRP) to provide primary-to-secondary cutover and also allows the active and standby VPN gateways to share a common virtual IP address.

NHRP network IDs are locally significant and can be different. It makes sense from a deployment and maintenance perspective to use unique network ID numbers (using the ip nhrp network-id command) across all routers in a DMVPN network, but it is not necessary that they be the same. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_conn_dmvpn/configuration/15-mt/sec-conn-dmvpn-15-mt-book/sec-conn-dmvpn-dmvpn.html

The user group is used in conjunction with Host Address to form a group-based URL. If you specify the Primary Protocol as IPsec, the User Group must be the exact name of the connection profile (tunnel group). For SSL, the user group is the group-url of the connection profile. https://www.cisco.com/c/en/us/td/docs/security/vpn_client/anyconnect/anyconnect40/administration/guide/b_AnyConnect_Administrator_Guide_4-0/anyconnect-profile-editor.html#ID-1430-0000026c

According to the Implementing Secure Solutions with Virtual Private Networks (SVPN) documents and learning resources available at cisco.com, the two features that provide headend resiliency for Cisco AnyConnect clients are:

• AnyConnect Backup Servers: This feature allows the AnyConnect client to automatically connect to a backup server in case the primary server is unreachable or fails. The backup server list is configured on the ASA or IOS headend and pushed to the client during the VPN connection establishment. The client can also manually select a backup server from the list if needed. This feature enhances the availability and reliability of the VPN service for the clients12.
• ASA failover: This feature enables two identical ASAs to be paired together as an active/standby or active/active pair. The ASAs synchronize their configuration and state information and monitor each other’s health. If the active ASA fails or becomes unreachable, the standby ASA takes over the traffic and VPN sessions without any disruption for the clients. This feature provides high availability and redundancy for the VPN headend34.

The correct answer is D. IKEv2 profile. A FlexVPN tunnel requires an IKEv2 profile to define the parameters for the IKEv2 negotiation and the IPsec security association. The IKEv2 profile references the IKEv2 keyring, the authentication method, the identity of the peers, and other options. The IKEv2 profile is then applied to a virtual tunnel interface (VTI) or a dynamic virtual tunnel interface (DVTI) to protect the tunnel with IPsec12. An EAP configuration is used for authentication with Extensible Authentication Protocol (EAP), which is optional for FlexVPN3. A multipoint GRE tunnel interface is used for DMVPN, not FlexVPN. An IKEv1 policy is used for IKEv1, not IKEv2, which is the protocol for FlexVPN.

Plug-ins are extensions to the Clientless SSL VPN feature that enable the ASA to handle non-standard applications and Web resources so that they display correctly over a Clientless SSL VPN connection. Plug-ins are software components that the ASA downloads to the remote user’s browser. The plug-ins provide support for applications and protocols that are not natively supported by Clientless SSL VPN, such as Java, ActiveX, SSH, Telnet, and RDP. Plug-ins can also provide enhanced functionality and security for Web applications, such as Outlook Web Access and Lotus iNotes.

You can read more about plug-ins and how to configure them in the document [ASDM Book 3: Cisco ASA Series VPN ASDM Configuration Guide, 7.7] 1.

The same-security-traffic intra-interface command lets traffic enter and exit the same interface, which is normally not allowed. This feature might be useful for VPN traffic that enters an interface, but is then routed out the same interface. The VPN traffic might be unencrypted in this case, or it might be reencrypted for another VPN connection. For example, if you have a hub and spoke VPN network, where the security appliance is the hub, and remote VPN networks are spokes, for one spoke to communicate with another spoke, traffic must go into the security appliance and then out again to the other spoke.

The first of the two TS payloads is known as TSi (Traffic Selector- initiator). The second is known as TSr (Traffic Selector-responder). TSi specifies the source address of traffic forwarded from (or the destination address of traffic forwarded to) the initiator of the Child SA pair. https://www.rfc-editor.org/rfc/rfc5996#page-40

If the responder's policy does not allow it to accept any part of the proposed Traffic Selectors, it responds with a TS_UNACCEPTABLE Notify message.

The MMNOSTATE failure occurs when the ISAKMP policy priority values are not configured correctly on both devices. The ISAKMP policy priority values are used to determine the order in which the ISAKMP policies are applied. If the priority values do not match between the two devices, the ISAKMP tunnel may not be established correctly, resulting in the MMNOSTATE failure. To resolve this issue, the engineer should ensure that the ISAKMP policy priority values are configured correctly on both the router and the peer.

This debug error appears if the pre-shared keys on the peers do not match. In order to fix this issue, check the pre-shared keys on both sides.

the show crypto ukev2 sa output from the ASA, the local selector is 192.168.0.0/24 the remote selector is 172.16.2.0/24 ( which is wrong , should be .20.0/24) . so , the ACL in the ASA should be to permit 192.168.0.0/24 to 172.16.20.0/24

The correct answer is A. Specify the trace using the -T option after the capture-traffic command. According to the document Use Firepower Threat Defense Captures and Packet Tracer, the capture-traffic command allows you to capture packets on the Snort engine domain of the FTD device. However, by default, it only shows the packet headers and does not include the Snort detection actions. To see the Snort detection actions, you need to use the -T option, which enables tracing. For example:

capture-traffic -T

This will show the packet headers along with the Snort verdicts, such as allow, block, or replace. You can also use other options to filter or save the capture output1.

B. Performing the trace within the Cisco FMC GUI instead of the Cisco FMC CLI is not a valid option, because the FMC GUI does not support packet capture or tracing on the FTD device. You can only use the FMC GUI to view and export captures that are taken on the FTD CLI1.

C. Using the verbose option as a part of the capture-traffic command is not a valid option, because there is no verbose option for this command. The verbose option is only available for the capture command, which is used to capture packets on the LINA engine domain of the FTD device1.

D. Using the capture command and specifying the trace option to get the required information is not a valid option, because the capture command does not have a trace option. The capture command allows you to capture packets on the LINA engine domain of the FTD device, but it does not show the Snort detection actions. The trace option is only available for the packet-tracer command, which is used to simulate a packet going through the FTD device and show its processing steps1.

KS (key server) is ‘caretaker’ of the GM group. Group registrations and authentication of GMs is taken care of by KS server. Any GM who wants to join the group is required to be successfully authenticated in the group and sends encryption keys and policy to be used within the group.

DMVPN disables the EIRGP next-hop-self with "no ip next-hop-self eigrp xxx" in DMVPN phase 2, and to go from Phase 2 to 3 you need use the NHRP protocol, and again enable EIRGP next-hop-self with "ip next-hop-self eigrp 134" under the tunnel interface https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_conn_dmvpn/configuration/15-mt/sec-conn-dmvpn-15-mt-book/sec-conn-dmvpn-dmvpn.html#GUID-BF561439-BCC0-4AAF-80D9-1F7876CB7B81

On a FlexVPN hub-and-spoke topology where spoke-to-spoke tunnels are not allowed, the command that is needed for the hub to be able to terminate FlexVPN tunnels is interface virtual-template. The interface virtual-template command is used to configure a virtual template interface which provides a secure tunnel for FlexVPN connections. The other commands listed - interface virtual-access, ip nhrp redirect, and interface tunnel - are not related to FlexVPN and are not used to terminate FlexVPN tunnels.
