Dell EMC D-RP-DY-A-24 Exam - Topic 6 Question 14 Discussion

Actual exam question for Dell EMC's D-RP-DY-A-24 exam

Question #: 14
Topic #: 6

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?

ASecondary sites are on different network subnets

BJumbo frames are not enabled on the IP network

CMTU size is to be set to 9000

Dboxmgmt password is different at the secondary sites

Show Suggested Answer

Suggested Answer: B

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.

Nah, I doubt it's the MTU size; that shouldn't be the main issue.

Secondary sites being on different subnets could be a factor too.

The boxmgmt password difference sounds familiar; I think it could definitely lead to connection issues between the sites.

I practiced a question about MTU sizes before, and I feel like it could be relevant, especially if it's not set correctly.

I think jumbo frames might be important for performance, but I can't recall if they directly affect the connection failure.

I remember something about network subnets causing issues, but I'm not sure if that's the main problem here.

The subnet issue sounds like the most likely cause to me. I'll make sure to carefully review the network setup and settings for each site before jumping to any conclusions.

Okay, let me see here. If the network team says the routing and connectivity are good, then it might be a configuration issue with the RecoverPoint cluster itself. I'd double-check the boxmgmt passwords across the sites.

Hmm, I'm not sure about this one. Could it be an issue with the MTU size or jumbo frames on the IP network? I'll have to think that through.

This one seems pretty straightforward. I'd start by checking the network subnets between the sites to see if they're on different networks.

Okay, I've got this. The controller VM in the HX220c has 48 GB of reserved memory. I'm confident that's the right answer.

I bet the network team forgot to configure the firewall rules correctly. That's usually the root cause of these kinds of connectivity issues.

The MTU size needs to be set to 9000 for this configuration to work. That's the key step that's missing.

Jumbo frames are definitely the culprit here. Without enabling them, the large data transfers required for the RecoverPoint cluster won't work.

I think the issue is with the different network subnets. The secondary sites need to be on the same subnet for the RecoverPoint cluster to connect properly.

I bet the real issue is that the network team forgot to order the 'magic internet connectivity' cable. You know, the one that makes everything work smoothly.

D) boxmgmt password is different at the secondary sites? Really? That sounds like a silly answer. Who would forget to set the same password across all the sites?
