Instance Metadata Traffic:

VPC flow logs do not capture traffic to and from the link-local address 169.254.169.254, which is used for accessing instance metadata (Option A).

DHCP Traffic:

DHCP traffic is not captured by VPC flow logs. This is because DHCP relies on broadcast and multicast traffic, which is excluded from flow logs (Option B).

Security Monitoring:

VPC flow logs can be used as a security tool to monitor the traffic that is reaching the instances. By analyzing the flow logs, administrators can detect suspicious activities and troubleshoot connectivity issues (Option D).

Other Considerations:

Option C is incorrect because flow logs do capture traffic to the reserved IP address of the default VPC router.

Option E is incorrect as VPC flow logs do not provide real-time log streams but rather capture data at intervals and deliver them to CloudWatch or S3.

Load Balancer Configuration Overview:

The provided configuration indicates that the ELB is an internet-facing load balancer.

Multi-AZ Load Balancing:

The load balancer is configured to distribute traffic across multiple availability zones (A, B, and C), ensuring high availability and fault tolerance (Option A).

Accessing Targets via DNS:

The DNS name of the load balancer (LabELB-716e15332f6401f8.elb.us-east-2.amazonaws.com) can be used to reach the targets behind the ELB, facilitating traffic routing to the appropriate instances (Option C).

Comparison with Other Options:

Option B is incorrect as the ARN is not used to access the load balancer directly.

Option D is incorrect because the load balancer is configured for internet-facing traffic, not just internal VPC traffic.

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.
