Fortinet NSE 8 - Written Exam (NSE8_812) Sample Questions (Q25-Q30):NEW QUESTION # 25
Review the VPN configuration shown in the exhibit.

What is the Forward Error Correction behavior if the SD-WAN network traffic download is 500 Mbps and has 8% of packet loss in the environment?
  • A. 2 redundant packet for every 8 base packets
  • B. 1 redundant packet for every 10 base packets
  • C. 3 redundant packet for every 9 base packets
  • D. 3 redundant packet for every 5 base packets
Answer: B
Explanation:
The FEC configuration in the exhibit specifies that if the packet loss is greater than 10%, then the FEC mapping will be 8 base packets and 2 redundant packets. The download bandwidth of 500 Mbps is not greater than 950 Mbps, so the FEC mapping is not overridden by the bandwidth setting. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.
Here is the explanation of the FEC mappings in the exhibit:
* Packet loss greater than 10%: 8 base packets and 2 redundant packets.
* Upload bandwidth greater than 950 Mbps: 9 base packets and 3 redundant packets.
The mappings are matched from top to bottom, so the first mapping that matches the conditions will be used.
In this case, the first mapping matches because the packet loss is greater than 10%. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.

NEW QUESTION # 26
Refer to the CLI output:

Given the information shown in the output, which two statements are correct? (Choose two.)
  • A. Reputation from blacklisted IP addresses from DHCP or PPPoE pools can be restored
  • B. The IP Reputation feature has been manually updated
  • C. Attackers can be blocked before they target the servers behind the FortiWeb.
  • D. An IP address that was previously used by an attacker will always be blocked
  • E. Geographical IP policies are enabled and evaluated after local techniques.
Answer: A,C
Explanation:
The CLI output shown in the exhibit indicates that FortiWeb has enabled IP Reputation feature with local techniques enabled and geographical IP policies enabled after local techniques (set geoip-policy-order after-local). IP Reputation feature is a feature that allows FortiWeb to block or allow traffic based on the reputation score of IP addresses, which reflects their past malicious activities or behaviors. Local techniques are methods that FortiWeb uses to dynamically update its own blacklist based on its own detection of attacks or violations from IP addresses (such as signature matches, rate limiting, etc.). Geographical IP policies are rules that FortiWeb uses to block or allow traffic based on the geographical location of IP addresses (such as country, region, city, etc.). Therefore, based on the output, one correct statement is that attackers can be blocked before they target the servers behind the FortiWeb. This is because FortiWeb can use IP Reputation feature to block traffic from IP addresses that have a low reputation score or belong to a blacklisted location, which prevents them from reaching the servers and launching attacks. Another correct statement is that reputation from blacklisted IP addresses from DHCP or PPPoE pools can be restored. This is because FortiWeb can use local techniques to remove IP addresses from its own blacklist if they stop sending malicious traffic for a certain period of time (set local-techniques-expire-time), which allows them to regain their reputation and access the servers. This is useful for IP addresses that are dynamically assigned by DHCP or PPPoE and may change frequently.

NEW QUESTION # 27
A customer's cybersecurity department needs to implement security for the traffic between two VPCs in AWS, but these belong to different departments within the company. The company uses a single region for all their VPCs.
Which two actions will achieve this requirement while keeping separate management of each department's VPC? (Choose two.)
  • A. Create a VPC with a FortiGate auto-scaling group with a Transit Gateway attached to the three VPC to force routing through the FortiGate cluster
  • B. Create a transit VPC with a FortiGate HA cluster, connect to the other two using VPC peering, and use routing tables to force traffic through the FortiGate cluster.
  • C. Migrate all the instances to the same VPC and create 1AM accounts for each department, then implement a new subnet for a FortiGate auto-scaling group and use routing tables to force the traffic through the FortiGate cluster.
  • D. Create an 1AM account for the cybersecurity department to manage both existing VPC, create a FortiGate HA Cluster on each VPC and IPSEC VPN to force traffic between the VPCs through the FortiGate clusters
Answer: A,B
Explanation:
To implement security for the traffic between two VPCs in AWS, while keeping separate management of each department's VPC, two possible actions are:
Create a transit VPC with a FortiGate HA cluster, connect to the other two using VPC peering, and use routing tables to force traffic through the FortiGate cluster. This option allows the cybersecurity department to manage the transit VPC and apply security policies on the FortiGate cluster, while the other departments can manage their own VPCs and instances. The VPC peering connections enable direct communication between the VPCs without using public IPs or gateways. The routing tables can be configured to direct all inter-VPC traffic to the transit VPC.
Create a VPC with a FortiGate auto-scaling group with a Transit Gateway attached to the three VPCs to force routing through the FortiGate cluster. This option also allows the cybersecurity department to manage the security VPC and apply security policies on the FortiGate cluster, while the other departments can manage their own VPCs and instances. The Transit Gateway acts as a network hub that connects multiple VPCs and on-premises networks. The routing tables can be configured to direct all inter-VPC traffic to the security VPC.

NEW QUESTION # 28
An administrator has configured a FortiGate device to authenticate SSL VPN users using digital certificates.
A FortiAuthenticator is the certificate authority (CA) and the OCSP server.
Part of the FortiGate configuration is shown below:

Based on this configuration, which authentication scenario will FortiGate deny?
  • A. FortiAuthenticator responds to an OCSP request that the user certificate authority is untrusted.
  • B. FortiAuthenticator responds to an OCSP request that the user certificate status is unknown.
  • C. The user certificate does not contain the OCSP URL.
Answer: A

NEW QUESTION # 29
A retail customer with a FortiADC HA cluster load balancing five webservers in L7 Full NAT mode is receiving reports of users not able to access their website during a sale event. But for clients that were able to connect, the website works fine.
CPU usage on the FortiADC and the web servers is low, application and database servers are still able to handle more traffic, and the bandwidth utilization is under 30%.
Which two options can resolve this situation? (Choose two.)
  • A. Disable SSL between the FortiADC and the web servers
  • B. Add more web servers to the real server poof
  • C. Change the persistence rule to LB_PERSIS_SSL_SESSJD.
  • D. Add a connection-pool to the FortiADC virtual server
Answer: C,D
Explanation:
The FortiADC HA cluster is a load balancing solution that distributes traffic among multiple web servers in L7 Full NAT mode. L7 Full NAT mode means that FortiADC terminates both client and server SSL connections and performs full NAT for both source and destination IP addresses and ports. One possible reason for users not being able to access the website during a sale event is that the persistence rule is not configured properly. Persistence rule is a feature that ensures that subsequent requests from the same client are sent to the same web server, which is important for maintaining session continuity and avoiding errors or data loss. The default persistence rule for L7 Full NAT mode is LB_PERSIS_SRC_IP, which uses the source IP address of the client as the persistence key. However, this rule may not work well if there are many clients behind a proxy or NAT device that share the same source IP address, or if there are clients that change their source IP address frequently due to roaming or switching networks. Therefore, to resolve this situation, one option is to change the persistence rule to LB_PERSIS_SSL_SESSJD, which uses the SSL session ID of the client as the persistence key. This rule can provide more accurate and reliable persistence for SSL connections than LB_PERSIS_SRC_IP. Another possible reason for users not being able to access the website during a sale event is that there are too many TCP connections being established and terminated between FortiADC and the web servers, which consumes CPU resources and causes performance degradation. Therefore, to resolve this situation, another option is to add a connection-pool to the FortiADC virtual server. Connection-pool is a feature that allows FortiADC to reuse existing TCP connections between FortiADC and the web servers, instead of creating new ones for each request. This can reduce CPU overhead, improve response time, and increase throughput.
