Netskope Updated NSK101 Exam Questions and Answers by ayana

In this scenario, there are three probable causes for the issue of users not being able to access external websites from their browsers after attempting to steer traffic to Netskope using GRE tunnels. One cause is that the configured GRE peer in the Netskope platform is incorrect, which means that the Netskope POP that is supposed to receive the GRE traffic from the customer’s network is not matching the IP address of the customer’s router that is sending the GRE traffic. This will result in a failure to establish a GRE tunnel between the customer and Netskope. Another cause is that the corporate firewall might be blocking GRE traffic, which means that the firewall rules are not allowing the GRE protocol (IP protocol number 47) or the UDP port 4789 (for VXLAN encapsulation) to pass through. This will result in a failure to send or receive GRE packets between the customer and Netskope. A third cause is that the route map was applied to the wrong router interface, which means that the configuration that specifies which traffic should be steered to Netskope using GRE tunnels was not applied to the correct interface on the customer’s router. This will result in a failure to steer the desired traffic to Netskope. The pre-shared key for the GRE tunnel is incorrect is not a probable cause for this issue, as GRE tunnels do not use pre-shared keys for authentication or encryption. Netskope does support GRE tunnels, so this is not a cause for this issue either. References: [Netskope Secure Forwarder], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 3: Steering Configuration, Lesson 3: Secure Forwarder.

Legacy solutions, such as on-premises firewalls and proxies, fail to secure the data and data access compared to Netskope Secure Web Gateway because they are designed for a perimeter-based security model, where the applications and the users are both within the corporate network. However, with the rise of cloud computing and remote work, this model is no longer valid. The applications where the data resides are no longer in one central location, but distributed across multiple cloud services and regions. The users accessing this data are not in one central place, but working from anywhere, on any device. Legacy solutions cannot provide adequate visibility and control over this dynamic and complex environment, resulting in security gaps and performance issues. Netskope Secure Web Gateway, on the other hand, leverages a cloud-native architecture that provides high-performance and scalable inspection of traffic from any location and device, as well as granular policies and advanced threat and data protection for web and cloud applications. References: Netskope Architecture OverviewNetskope Next Gen SWG

The term that correctly defines the Zero Trust security model is least privilege access. The Zero Trust security model is a modern security strategy based on the principle: never trust, always verify. Instead of assuming everything behind the corporate firewall is safe, the Zero Trust model assumes breach and verifies each request as though it originates from an open network. One of the core principles of the Zero Trust model is to use least privilege access, which means granting users or systems only the minimum level of access they need to perform their tasks, and only for a limited time. This helps reduce the attack surface and minimize the impact of a potential breach. References: Zero Trust Security - microsoft.comWhat is Zero Trust Security? Principles of the Zero Trust Model

To deploy Netskope’s zero trust network access (ZTNA) solution, NPA, you need to enable Steer all Private Apps in your existing steering configuration(s) from the admin console. This will allow you to create private app profiles and assign them to your applications. NPA will then provide secure and granular access to your applications without exposing them to the internet or requiring VPNs. References: [Netskope Private Access (NPA) Deployment Guide]
