Exhibit.
The LTM devices LTM1 and LTM2 are configured in a Device Group (Sync Failover) with Network Failover configured on both the management and HA and Internal VLANS. and ConfigSync is confined in a Device Group (Sync Failover) with Network Failover and internal are tagged on a single trunk with subnets Connection Mirroring is configured on both the HA interlace directly connected between LTM1 and LTM2, and the management interlace is connected to a management switch. The LTM devices have four Traffic Groups defined, and both LTM devices are healthy and capable of passing traffic for any of the Traffic Groups.
An LTM Specialist disconnects the cable for the HA network in an effort to test failover.

Surprised to see so many think Connection Mirroring is unaffected!
OL

Definitely B, both should work fine!

I thought ConfigSync might still work in some cases?
DU

Totally agree, Connection Mirroring should still function.
OR

ConfigSync won't work if HA is disconnected.

I'm leaning towards D, but I can't recall if Connection Mirroring needs the HA link too. It’s a bit confusing!

This question feels similar to one we practiced where the HA link was tested. I think ConfigSync definitely fails in that scenario.

I think Connection Mirroring might still function even if the HA network is disconnected, but I'm not entirely sure.
AL

I remember studying that ConfigSync relies on the HA network, so if that's down, it probably won't work.

Whoa, this is a tricky one. There are a lot of moving parts to consider. I'm going to take my time and methodically work through the information provided.
SH

Okay, I think I've got this. The key is understanding how ConfigSync and Connection Mirroring work when the HA network goes down. I'm confident I can figure out the right answer.
EA

Hmm, the scenario describes a lot of configuration details. I'll need to carefully read through it and think through the impact of disconnecting the HA network.

This question seems straightforward, but I want to make sure I understand the details correctly before selecting an answer.

Trick question! The real answer is E: Disconnect the cable, then run away before the LTM devices figure out what's going on. Just kidding, I'll stick with C.

I'm feeling pretty confident about B. If the devices are in a Device Group (Sync Failover), then ConfigSync and Connection Mirroring should both continue to function even with the HA network disconnected.
JO
Josephine

Yeah, I'm also leaning towards B. It makes sense that those functionalities would still work even without the HA network connection.
AR
Arlean
1 year ago
I agree, B seems like the most logical choice. The devices should still be able to sync and mirror connections.
JU
Julianna

I think B is the correct answer too. ConfigSync and Connection Mirroring should still work even with the HA network disconnected.
KA

Ah, the old HA network disconnect test. Classic move, LTM Specialist! I'd go with C, since ConfigSync is a device-level feature and should still work even with the HA network down.
ZE
Zena
1 year ago
Yeah, I think ConfigSync works but Connection Mirroring does not work when the HA network is disconnected.
RA
Raelene
1 year ago
I agree. Connection Mirroring may not work without the HA network, but ConfigSync should still function.
BL
Blondell
1 year ago
I'm not sure about Connection Mirroring, but I think ConfigSync should still function properly.
LE
Leota
1 year ago
Yeah, ConfigSync is independent of the HA network, so it should work fine in this scenario.
SA
Salena
1 year ago
I think C is the right answer too. ConfigSync should still work even with the HA network disconnected.
FA
Fabiola
1 year ago
But what about Connection Mirroring? Do you think that would still work in this scenario?
PA
Patti
1 year ago
I agree, ConfigSync is a device-level feature so it should still work even with the HA network down.
CA

Hmm, I'm not sure about this one. I'd say D seems plausible, but I better double-check the details on ConfigSync and Connection Mirroring.
ST
Stephanie
1 year ago
User2: Yeah, I agree. Let's double-check the details just to be sure.
DE
Derrick

User1: I think D is the correct answer. ConfigSync does NOT work but Connection Mirroring works.
BE
Belen

I think the correct answer is C. ConfigSync works, but Connection Mirroring does not work since the HA network was disconnected. Without the HA network, the two devices can't communicate to mirror connections.
CH
Chuck

Exactly, ConfigSync allows the devices to synchronize their configuration even if the HA network is disconnected.
CA
Carmela

So, the HA functionality that works in this case is ConfigSync.
LO
Lore

Yes, you are right. ConfigSync works, but Connection Mirroring does not work without the HA network.
LI
Ling

I think the correct answer is C.
MA
