Free Fortinet NSE7_NST-7.2 Exam Actual Questions

Note: Premium Questions for NSE7_NST-7.2 were last updated On Jun. 03, 2024 (see below)

Question #1

Which statement is correct regarding LDAP authentication using the regular bind type?

Reveal Solution Hide Solution
Correct Answer: A

LDAP Authentication Process:

The regular bind type for LDAP authentication involves multiple steps to verify user credentials.

Step 1: The client sends a bind request with the username to the LDAP server.

Step 2: The LDAP server responds to the bind request.

Step 3: The client sends a bind request with the password.

Step 4: The LDAP server responds, confirming or denying the authentication.

Explanation of Answer:

The regular bind type follows these four steps to authenticate a user, making it a comprehensive method but not necessarily the easiest to configure.

The statement regarding sAMAccountName and super_admin account requirements are not accurate in the context of regular bind type LDAP authentication on FortiOS.

Question #2


Refer to the exhibit, which contains the partial output of the get vpn ipsec tunnel details command. Based on the output, which two statements are correct? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, C

Anti-replay Enabled:

The exhibit shows replay: enabled, which confirms that anti-replay is enabled for this IPsec tunnel. Anti-replay is a security feature that prevents replay attacks by ensuring that packets are not duplicated or reused.

NPU Acceleration:

The NPU acceleration: encryption (outbound) decryption (inbound) line indicates that Network Processing Unit (NPU) acceleration is used.

The npu_flag for this tunnel is 02. This indicates that encryption and decryption are handled by the NPU, improving the performance of the VPN tunnel.

Question #3


Refer to the exhibit, which contains partial output from an IKE real-time debug.

The administrator does not have access to the remote gateway.

Based on the debug output, which configuration change can the administrator make to the local gateway to resolve the phase 1 negotiation error?

Reveal Solution Hide Solution
Correct Answer: B

Analyzing Debug Output:

The debug output shows multiple proposals with encryption algorithms like AES CBC and hashing algorithms like SHA256.

The negotiation failure (no SA proposal chosen) suggests that there is a mismatch in the encryption or hashing algorithms between the local and remote gateways.

Configuration Change:

To resolve the phase 1 negotiation error, the local gateway needs to include a compatible proposal.

Adding AES256-SHA256 to the phase 1 proposal configuration ensures that both gateways have a matching set of encryption and hashing algorithms.

Question #4

Which two statements about application-layer test commands ate true? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, B

Statistics and Configuration Information:

Application-layer test commands can display detailed statistics and configuration information about specific features or processes. For example, commands like diagnose vpn ipsec tunnel list provide detailed statistics about VPN tunnels.

Real-time Debugs:

These commands also facilitate real-time debugging of applications and processes. For instance, using diagnose debug application followed by the specific application, such as fssod, provides real-time debug information which is crucial for troubleshooting.

Question #5

Which exchange lakes care of DoS protection in IKEv2?

Reveal Solution Hide Solution
Correct Answer: B

IKE_SA_INIT Exchange:

The IKE_SA_INIT exchange is the first step in the IKEv2 negotiation process. It is responsible for setting up the initial security association (SA) and performing Diffie-Hellman key exchange.

During this exchange, the responder may employ various measures to protect against Denial of Service (DoS) attacks, such as rate limiting and the use of puzzles to increase the computational cost for an attacker.

DoS Protection Mechanisms:

One key method involves limiting the number of half-open SAs from any single IP address or subnet.

The IKE_SA_INIT exchange can also incorporate the use of stateless cookies, which help to verify the initiator's legitimacy without requiring extensive resource allocation by the responder until the initiator is verified.
