NAT

1

are the terms used to refer to the mechanism that allows IPv6 addressed hosts to communicate with IPv4 addressed hosts and the reverse.

1

Without the mechanism NAT64 and 46, an IPv6 node on a network, such as a corporate LAN, would not be able to communicate with a website that was in an IPv4-only environment, and IPv4 environments would not be able to connect to IPv6 networks.

Which statement about NAT66 is true?

are a mechanism that allow sessions leaving the FortiGate ﬁrewall to use NAT. Deﬁnes a single IP address or a range of IP addresses to be used as the source address for the duration of the session. These assigned addresses will be used instead of the IP address assigned to that FortiGate interface.

There are four types of IP pools that can be conﬁgured on the FortiGate ﬁrewall:

1

What is the default IP pool type?

1

Which of the following is the default VIP type?

1

Which one of the following statements is true?

1

What happens if NAT is enabled on a firewall policy and there is no matching central SNAT policy or no central SNAT policy configured?

1

Which method would be used for advanced application tracking and control?

1

Which profile is an example of application layer gateway?

If session diagnostic output indicates that a TCP protocol state is proto_state=01, which of the following statements is true?

An administrator wants to check the total number of TCP sessions for an IP pool named INTERNAL. Which one of the following CLI commands should the administrator use?

Which of the following statements about NAT port exhaustion is true?

❌ : Changes the IP layer address of a packet
- Some protocols, like SIP, have addresses at the application layer, requiring session helpers or proxies
-Source NAT (SNAT)
-Destination NAT (DNAT)

❌ : Changes the IP layer port number of a packet

❌ : mechanism that allows IPv6 addressed hosts to communicate with IPv4 addressed hosts and the reverse
