Explanation

FlexVPN is an IKEv2-based VPN technology that provides several benefits beyond traditional site-to-site VPN implementations. FlexVPN is a standards-based solution that can interoperate with non-Cisco IKEv2

implementations. Therefore FlexVPN can support a multivendor environment. All of the three VPN technologies support traffic between sites (site-to-site or spoke-to-spoke).

SAML is designed to exchange authentication and authorization assertions between an identity provider and a service provider, so B is correct. In a Duo SSO flow, the protected application redirects the user to Duo, Duo performs primary authentication and policy or multifactor checks, and the resulting SAML assertion communicates the authenticated identity back to the application. Cisco Duo’s Single Sign-On documentation identifies Duo SSO as a cloud-hosted SAML 2.0 identity provider and explains that SAML delegates application authentication to an identity provider. SCEP enrolls devices for certificates, SCP securely copies files over SSH, and EAP provides an authentication framework commonly used for network access such as 802.1X. Those protocols do not transport browser-based SSO assertions between Duo and a SAML service provider.

Explanation

As the new device does not have a supplicant, we cannot use 802.1X.

MAC Authentication Bypass (MAB) is a fallback option for devices that don’t support 802.1x. It is virtually

always used in deployments in some way shape or form. MAB works by having the authenticator take the

connecting device’s MAC address and send it to the authentication server as its username and password. The authentication server will check its policies and send back an Access-Accept or Access-Reject just like it would with 802.1x.

Cisco ISE Profiling Services provides dynamic detection and classification of endpoints connected to the

network. Using MAC addresses as the unique identifier, ISE collects various attributes for each network

endpoint to build an internal endpoint database. The classification process matches the collected attributes to prebuilt or user-defined conditions, which are then correlated to an extensive library of profiles. These profiles include a wide range of device types, including mobile clients (iPads, Android tablets, Chromebooks, and so

on), desktop operating systems (for example, Windows, Mac OS X, Linux, and others), and numerous non-user systems such as printers, phones, cameras, and game consoles.

Once classified, endpoints can be authorized to the network and granted access based on their profile. For example, endpoints that match the IP phone profile can be placed into a voice VLAN using MAC Authentication Bypass (MAB) as the authentication method. Another example is to provide differentiated network access to users based on the device used. For example, employees can get full access when accessing the network from their corporate workstation but be granted limited network access when accessing the network from their personal iPhone.

A site-to-site VPN establishes an encrypted connection between VPN gateways so that hosts on two protected private networks can communicate across an untrusted network. A remote-access VPN instead provides an individual user or endpoint with an encrypted connection to a private network, normally through client software or a clientless access method. Therefore, D accurately states the architectural difference. GET VPN, GRE over IPsec, and virtual tunnel interfaces are particular technologies or implementation choices; they do not define the universal distinction between the two VPN categories. Option A reverses the roles and incorrectly makes software endpoints characteristic of site-to-site VPNs. The determining factor is whether the tunnel joins entire networks through VPN gateways or connects an individual remote endpoint to protected organizational resources. Cisco VPN overview

Explanation

In this IaaS model, cloud providers offer resources to users/machines that include computers as virtual

machines, raw (block) storage, firewalls, load balancers, and network devices.

Note: Cloud access security broker (CASB) provides visibility and compliance checks, protects data against misuse and exfiltration, and provides threat protections against malware such as ransomware.

Explanation

A buffer overflow (or buffer overrun) occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program attempting to write the data to the buffer overwrites adjacent memory locations.

Buffer overflow is a vulnerability in low level codes of C and C++. An attacker can cause the program to crash, make data corrupt, steal some private information or run his/her own code. It basically means to access any buffer outside of it’s alloted memory space. This happens quite frequently in the case of arrays.

Using an Internet browser to access cloud-based service creates the risk of insecure implementation of API. API stands for Application Programming Interface, which is a set of rules and protocols that allow different applications or services to communicate and exchange data. API is often used to access cloud-based service, such as software as a service (SaaS), platform as a service (PaaS), or infrastructure as a service (IaaS). However, if the API is not implemented securely, it can expose sensitive data or allow unauthorized access to the cloud service. For example, an API may not use encryption, authentication, or authorization mechanisms to protect the data in transit or at rest. An API may also have vulnerabilities such as injection, broken authentication, or insufficient logging and monitoring, which can be exploited by attackers to compromise the cloud service or the user’s browser. Therefore, it is important to follow the best practices and standards for secure API development and testing, such as OWASP API Security Top 10. References:

An active/active FlexVPN configuration allows for multiple routers or VRFs to act as hubs for different VPN groups, providing load balancing and redundancy1. This is useful when the VPN deployment has a large number of spokes or different security policies for different groups of spokes. DMVPN, on the other hand, only supports a single hub or a pair of hubs in active/standby mode for each VPN group2. This limits the scalability and flexibility of DMVPN deployments. Therefore, an engineer would opt for an active/active FlexVPN configuration as opposed to DMVPN when multiple routers or VRFs are required. References :=

Cisco Talos Incident Response provides proactive readiness services in addition to emergency incident handling. Threat hunting searches customer environments for concealed or previously undetected malicious activity, while cyber range training lets response teams practise investigation, coordination, and decision-making in realistic attack scenarios. Cisco’s Talos Incident Response service page explicitly identifies Talos IR Threat Hunting, and the Talos incident-response portal lists Cyber Range Training among available service engagements. Security policy authorization is an internal governance responsibility, not an incident-response service. Product bug discovery and coordination belong more closely to vulnerability research and PSIRT functions. Talos experts can recommend containment and remediation, but the service does not automatically remediate every vulnerability in a customer environment. Consequently, threat hunting and cyber range training are the two valid services.

Dual-SSID BYOD is the term for when an endpoint is associated to a provisioning WLAN that is shared with guest access, and the same guest portal is used as the BYOD portal. This flow is a unique capability of ISE where the user does not have to log in twice, as ISE can take the user information from the 802.1X session and direct the user to the BYOD flow. Once the endpoint is onboarded, it is reconnected to the secured WLAN for full network access. This flow is different from single-SSID BYOD, where the endpoint associates to a secure WLAN, gets onboarded, and then reconnects to the same WLAN12. References: 1: ISE BYOD: Dual vs. Single SSID Onboarding - Cisco Community 2: Cisco ISE BYOD Prescriptive Deployment Guide - Cisco Community

The missing global command is dot1x system-auth-control, which activates 802.1X processing on the switch. The access interfaces must also operate as Port Access Entity authenticators, so dot1x pae authenticator is required on ports connected to workstation supplicants. Cisco’s Catalyst 9300 802.1X configuration guide identifies the global command and the interface PAE role as elements of port-based authentication. Dynamic authorization supports Change of Authorization and is not required to initiate authentication. A RADIUS source interface is unnecessary when connectivity and RADIUS addressing already work. The mab command enables MAC Authentication Bypass for devices without an 802.1X supplicant; these workstations have functioning supplicants, so MAB is not the missing 802.1X control. Thus, A and C address the failure described.
