To enforce complex passwords—for example, to require that a password contain upper- and lowercase letters, numbers, and special characters—enter the password-management command in tunnel-group general-attributes configuration mode on the ASA and perform the following steps under Active Directory. https://www.cisco.com/c/en/us/td/docs/security/asa/asa97/configuration/vpn/asa-97-vpn-config/vpn-groups.html

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.

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.

IKE Message from X.X.X.X Failed its Sanity Check or is Malformed

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.

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.

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.

The IKEv2 CREATE_CHILD_SA packet is used to establish a new security association (SA) between two peers. This packet contains the details of the exchange, including the traffic selectors, the cryptographic algorithms and keys to be used, and any other relevant information

Reverse route injection (RRI) is a method that dynamically installs the network routes for remote tunnel endpoints. The RRI feature allows the router to automatically learn the routes for the remote networks and automatically install these routes into the routing table. This eliminates the need for the administrator to manually configure and maintain the routes for the remote networks. This feature is commonly used in VPN environments, where the router at the VPN endpoint needs to learn the routes for the remote networks behind the other VPN endpoint. The other options such as policy-based routing, CEF, and route filtering are not used to dynamically install the network routes for remote tunnel endpoints

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

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.

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

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 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.

When you configure other group policies, any attribute that you do not explicitly specify takes its value from the default group policy. To view the default group policy. https://www.cisco.com/c/en/us/td/docs/security/asa/asa72/configuration/guide/conf_gd/vpngrp.html

HTTP (Hypertext Transfer Protocol) is used for transferring web resources, such as web pages and HTML documents, across the internet. CIFS (Common Internet File System) is used for sharing files and printers between computers on a network. ICA (Citrix), VNC (Virtual Network Computing), and RDP (Remote Desktop Protocol) are not enabled by default on the Cisco ASA Clientless SSL VPN portal.
