NSE6_WCS-7.0 Exam Dumps - Fortinet NSE 6 - Cloud Security 7.0 for AWS

Symmetric Traffic Flow with SNAT:

In active-active (A-A) clusters, symmetric traffic flow is essential for maintaining session integrity across multiple instances. Source Network Address Translation (SNAT) is performed inbound to ensure that return traffic is routed correctly (Option A).

Load Balancer Requirement:

A-A clusters require a load balancer to distribute incoming traffic evenly across the active instances. This is crucial for balancing the load and providing high availability (Option C).

API Calls and Failovers:

Option B is incorrect because failovers in A-A clusters do not typically rely on API calls but are managed by the load balancer and the clustering mechanism itself.

Software-Defined Network (SDN) Failover:

Option D is incorrect as SDN is not specifically required for performing failovers in A-A clusters. The failover mechanism is typically managed by the load balancer and FortiGate's clustering technology.

Understanding Gateway Load Balancer (GWLB):

GWLB is designed to distribute traffic across multiple appliances for both inbound and outbound traffic, providing scalability and high availability.

Traffic Load Balancing:

GWLB can send traffic to multiple FortiGate appliances for load balancing purposes, ensuring efficient use of resources (Option A).

Stateful Processing:

For stateful processing, GWLB ensures that traffic flows (both inbound and outbound) for a given connection are directed to the same FortiGate appliance. This maintains session integrity (Option B).

Preservation and Hashing of Traffic:

Options C and D are incorrect as they suggest incorrect behavior regarding traffic content preservation and hashing for data integrity, which are not primary functions of GWLB.
