Netskope Certified Cloud Security Administrator (NCCSA) NSK101 Exam Questions with Experts Answers Updated Recently

The inline and API implementation of the Netskope platform are two different ways of connecting cloud applications to Netskope for inspection and policy enforcement. Two fundamental differences between them are: The API implementation can only be used with sanctioned applications, which are applications that are approved and authorized by the organization for business use. The API implementation relies on using out-of-band API connections to access data and events from these applications and apply near real-time policies. The inline implementation can effectively block a transaction in both sanctioned and unsanctioned applications, which are applications that are not approved or authorized by the organization for business use. The inline implementation relies on using in-band proxy or reverse-proxy connections to intercept traffic to and from these applications and apply real-time policies. The API implementation can be used with both sanctioned and unsanctioned applications and the inline implementation can only effectively block a transaction in sanctioned applications are not true statements, as they contradict the actual capabilities and limitations of each implementation method. References: [Netskope SaaS API-enabled Protection], [Netskope Inline CASB].

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.
