NSE 8 – Network Security Expert (811) — Question 49

You are building a FortiGate cluster which is stretched over two locations. The HA connections for the cluster are terminated on the local switches in the data centers. Once the FortiGate devices have booted, they do not form a cluster. The network operators inform you that CRC errors are present on the switches where the FortiGate devices are connected.
What should you do to solve this problem?

Answer options

• A. Set the speed/duplex setting to 1 Gbps / Full Duplex.
• B. Replace the cables where the CRC errors occur.
• C. Place the HA interfaces in dedicated VLANs.
• D. Change the ethertype for the HA packets.

Correct answer: D

Explanation

The correct answer is D because changing the ethertype for the HA packets can help ensure proper packet handling and reduce CRC errors that may interfere with cluster formation. Options A and B do not directly address the CRC errors, while option C, although it may help with network management, does not resolve the underlying issue of CRC errors affecting cluster communication.
