Important Fortinet NSE8_812 Exam Questions

Answer: B, D, E

Explanation:

Bmust be set to enable mode-cfg, which is required for injecting IKE routes on the ADVPN shortcut tunnels.

Dmust be set to enable add-route, which is the command that actually injects the IKE routes.

Emust be set to enable mode-cfg-allow-client-selector, which allows custom phase 2 selectors to be configured.

The other options are incorrect. Option A is incorrect because net-device disable is not required for injecting IKE routes on the ADVPN shortcut tunnels. Option C is incorrect because IKE version 1 is not supported for ADVPN.

Configuring SD-WAN/ADVPN with FortiGate | FortiGate / FortiOS 7.2.0

Answer: A, D

Answer: B, E

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.

https://docs.fortinet.com/document/fortiweb/7.4.2/administration-guide/608374/ip-reputation-blocklisting-source-ips-with-poor-reputation Fortinet compiles a reputation for each public IP address. Clients will have poor reputations if they have been participating in attacks, willingly or otherwise. Because blacklisting innocent clients is equally undesirable, Fortinet also restores the reputations of clients that improve their behavior. This is crucial when an infected computer is cleaned, or in DHCP or PPPoE pools where an innocent client receives an IP address that was previously leased by an attacker.
