An organization plans to connect three different sites over IP using a RecoverPoint cluster at each site. However, the cluster fails to connect. The network team has determined that the required IP routing and WAN connectivity is in place. The desired routing information is added while running the Deployment Manager wizard.

What is a possible cause for the failure?

Answers
D.
boxmgmt password is different at the secondary sites
Suggested answer: B

Explanation:

When connecting RecoverPoint clusters over IP, it is crucial that the network infrastructure supports the data transmission requirements of RecoverPoint.

Jumbo frames are larger than standard Ethernet frames and can carry more data, reducing overhead and improving performance1.

If jumbo frames are not enabled on the IP network, the RecoverPoint clusters may fail to connect due to the inability to handle the larger data packets required for efficient replication and synchronization2.

The MTU (Maximum Transmission Unit) size also plays a role in this process. An MTU size of 9000 is often recommended for jumbo frames, but if the network devices do not support this configuration, it can lead to connection issues2.

It's important to ensure that all network devices along the path support jumbo frames and are configured correctly to allow for the larger MTU size required by RecoverPoint clusters1.

For detailed troubleshooting steps and to confirm the exact cause of the connection failure, refer to the Dell RecoverPoint documentation or contact Dell EMC support for assistance. The information provided here is based on general knowledge of networking requirements for RecoverPoint systems and may not reflect the most recent updates or specific configurations.
