A customer has implemented GWLB between the partner and application VPCs. FortiGate appliances are deployed in the partner VPC with multiple AZs to inspect traffic transparently.
Which two things will happen to application traffic based on the GWLB deployment? (Choose two.)
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.

Refer to the exhibit.
An administrator configured a FortiGate device to connect to the AWS API to retrieve resource values from the AWS console to create dynamic objects for the FortiGate policies. The administrator is unable to retrieve AWS dynamic objects on FortiGate.
Which two reasons can explain why? (Choose two.)
Invalid Credentials:
The debug output shows an 'AuthFailure' error, indicating that AWS was not able to validate the provided access credentials. This usually points to incorrect or invalid AWS access or secret keys configured in the AWS Lab SDN connector (Option C).
Clock Skew:
Another common reason for authentication failures in AWS API calls is a clock skew between the FortiGate device and AWS. AWS requires that the system time of the client making the API call is synchronized with its own time, within a small margin. If there is a significant time difference, AWS will reject the credentials (Option B).
Other Options Analysis:
Option A is incorrect because the AWS API supports XML version 1.0.
Option D is incorrect as the error message does not indicate an issue with connecting on port 401.
Option E is incorrect because the error is related to authentication, not the absence of instances.

An AWS administrator is designing internet connectivity for an organization's virtual public cloud (VPC). The organization has web servers with private addresses that must be reachable from the internet. The web servers must be highly available.
Which two configurations can you use to ensure the web servers are highly available and reachable from the internet? (Choose two.)
Network Load Balancer:
Deploying a network load balancer ensures that incoming traffic is distributed across multiple web servers, providing high availability and redundancy. This setup helps in managing traffic efficiently and maintaining service uptime even if some servers fail (Option A).
Multiple Availability Zones:
Deploying web servers in multiple availability zones (AZs) enhances fault tolerance and availability. If one AZ goes down, servers in other AZs can continue to handle the traffic, ensuring the web application remains accessible (Option D).
Other Options Analysis:
Option B is incorrect because NAT Gateways are used to provide internet access to instances in private subnets, not to make private addresses reachable from the internet.
Option C is not sufficient on its own for high availability. Adding a route to the default VPC route table forwarding traffic to the internet gateway makes the VPC internet-accessible but does not ensure high availability.

Refer to the exhibit.
An organization deployed the application servers in the AWS VPC that connects to the corporate data center using Transit Gateway Connect. Demand for the applications has grown and the connection requires more bandwidth.
What is required to achieve higher bandwidth?
Understanding Transit Gateway Connect:
Transit Gateway Connect is a feature of AWS Transit Gateway that simplifies the integration of SD-WAN networks with AWS. It uses Generic Routing Encapsulation (GRE) tunnels to facilitate this connection.
GRE Tunnels and Bandwidth:
GRE tunnels can dynamically scale to meet increasing bandwidth demands. They allow multiple tunnels between the same endpoints, which can aggregate bandwidth without requiring additional configuration.
Scaling Bandwidth with GRE:
The GRE protocol used by Transit Gateway Connect can support high bandwidth requirements by spreading traffic across multiple tunnels. As demand grows, additional tunnels can be automatically used to handle the increased traffic load.
Comparison with Other Options:
Option A suggests using public IP addresses, which is not relevant to bandwidth scaling.
Option B is incorrect because bandwidth can be increased through GRE scaling.
Option D suggests adding a Transit VPC, which is unnecessary for increasing bandwidth when using Transit Gateway Connect.
Your organization is deciding between deploying an active-active (A-A) or active-passive (A-P) FortiGate high availability (HA) cluster in AWS cloud.
Which two statements are true about A-A clusters compared to A-P clusters? (Choose two.)
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.
