Refer to the exhibit, which shows oneway communication of the downstream FortiGate with the upstream FortiGate within a Security Fabric.



What three actions must you take to ensure successful communication? (Choose three.)

  1. Ensure the port for Neighbor Discovery has been changed.
  2. FortiGate must not be in NAT mode.
  3. Ensure TCP port 8013 is not blocked along the way
  4. You must authorize the downstream FortiGate on the root FortiGate.
  5. You must enable Security Fabric/Fortitelemetry on the receiving interface of the upstream FortiGate.

Answer(s): C,D,E

Explanation:

The exhibit shows a sniffer capture where TCP port 8013 is being used for communication. The communication appears one-way, indicating potential issues with the upstream FortiGate receiving the necessary packets or being able to respond.

To ensure successful communication in a Security Fabric setup:

Ensure TCP port 8013 is not blocked along the way: Verify that no firewalls or network devices between the downstream and upstream FortiGates are blocking TCP port 8013. This port is crucial for Security Fabric communication.

Authorize the downstream FortiGate on the root FortiGate: In the Security Fabric, the root FortiGate must recognize and authorize the downstream FortiGate to allow proper communication and management.

Enable Security Fabric/Fortitelemetry on the receiving interface of the upstream FortiGate: The upstream FortiGate must have the Security Fabric or Fortitelemetry enabled on the interface that receives the communication from the downstream FortiGate. This enables proper data exchange and monitoring within the Security Fabric.

Refer to the exhibit, which shows the output of a BGP debug command.



Which statement explains why the state of the 10.200.3.1 peer is Connect?

  1. The local router initiated the BGP session to 10.200.3.1 but did not receive a response.
  2. The local router is receiving BGP keepalives from the remote peer, but the local peer has not received the OpenConf inn yet.
  3. The router 10.200.3.1 has authentication configured for BGP and the local router does not.
  4. The local router has a different AS number than the remote peer.

Answer(s): A

Explanation:

The BGP summary output shows the state of the 10.200.3.1 peer as "Connect." This state indicates that the local router has attempted to initiate a BGP session with the peer, but the peer has not yet responded to the initial connection request.

State The "Connect" state in BGP indicates that the TCP connection has been initiated but is waiting for a response. If the peer does not respond within the configured timers, the session will transition to the "Active" state and retry the connection.

Possible Causes: This can occur due to network issues preventing the peer from responding, a misconfiguration on the peer device, or issues like access control lists (ACLs) blocking the BGP traffic.

To troubleshoot, check the connectivity between the routers, ensure that the BGP configurations on both sides match, and verify that there are no firewalls or ACLs blocking the BGP packets.

Refer to the exhibit, which shows two entries that were generated in the FSSO collector agent logs.



What three conclusions can you draw from these log entries? (Choose three.)

  1. Remote registry is not running on the workstation.
  2. The FortiGate firmware version is not compatible with that of the collector agent
  3. DNS resolution is unable to resolve the workstation name.
  4. The user's status shows as "not verified" in the collector agent
  5. A firewall is blocking traffic to port 139 and 445.

Answer(s): A,C,E

Explanation:

The exhibit shows log entries from the FSSO (Fortinet Single Sign-On) collector agent logs. These logs provide insights into why there might be issues with the collector agent connecting to workstations or the registry.

Remote registry is not running on the workstation: The failure to connect to the workstation registry can occur if the remote registry service on the workstation is not running. This service needs to be active to allow the FSSO collector agent to query the workstation for user login information.

DNS resolution is unable to resolve the workstation name: The logs indicate a failure in connecting to a workstation by name, which can happen if the DNS server is unable to resolve the workstation's name to an IP address. This is a common issue when the DNS settings are incorrect or the workstation name is not properly registered in the DNS.

A firewall is blocking traffic to port 139 and 445: Communication issues to the workstation or registry are often caused by firewall rules blocking essential ports. Ports 139 (NetBIOS) and 445 (SMB) are critical for these operations. Ensure these ports are open on both the workstation and any intermediate firewalls.

Refer to the exhibit, which shows the output of a real-time debug.



Which statement about this output is true?

  1. The server hostname was extracted from the SNI in the client request, or from the CN in the server certificate
  2. FortiGate found the requested URL in its local cache.
  3. This web request was inspected using the rtgd-allow web filter profile.
  4. The requested URL belongs to category ID 255.

Answer(s): A

Explanation:

The exhibit displays the output of a real-time debug of the URL filtering process on a FortiGate device. The debug output includes various details about a web request being processed.

SNI (Server Name Indication): This is part of the SSL/TLS handshake where the client specifies the hostname it is trying to connect to. FortiGate can use this information to apply appropriate web filtering rules based on the server name.

CN (Common Name): This is a field in the server's SSL certificate that typically contains the server's hostname. FortiGate can extract this information to verify the identity of the server and apply security policies accordingly.

Given that the debug output includes the hostname "training.fortinet.com," it is likely derived from the SNI in the client's request or the CN in the server's certificate, indicating that FortiGate is using this information to process the web request.
