[All NIOS-DDI-Expert Questions]

How does the passive member of a High Availability (HA) pair receive its database updates?

ASSL VPN from the Active node

BSSL VPN from the Grid Master

CbloxSync from the Active node

DbloxSync from the Grid Master

Show Suggested Answer

Suggested Answer: C

Comprehensive and Detailed In-Depth

In an HA pair, the passive node stays synchronized with the active node to ensure seamless failover. This synchronization uses bloxSync, a proprietary Infoblox protocol that securely transfers database updates (e.g., DNS records, DHCP leases) between the HA pair members over an SSL-encrypted connection. The active node, being the operational member, directly provides these updates to the passive node. The Grid Master handles Grid-wide sync, but within an HA pair, the active node is the source. Options A and B misrepresent the mechanism (it's not a traditional VPN), and Option D incorrectly attributes the sync to the Grid Master. This is a critical HA troubleshooting topic in the INE course.

Yeah, bloxSync is the way to go for HA pairs.

It's definitely bloxSync from the Active node!

Agreed, the Active node handles the updates for the passive member.

Wait, are we sure about that? Sounds a bit off.

I’m leaning towards option C, but I have a nagging feeling that it could also be related to the Grid Master. This is confusing!

I feel like the Grid Master plays a role in managing updates, but I can't recall if it's the one sending them to the passive member.

I remember practicing a question about HA pairs, and I think it mentioned the Active node sending updates directly. Could it be option C?

I think the passive member gets updates through some kind of sync process, but I'm not sure if it's bloxSync or something else.

This seems like a straightforward networking question. The passive node needs to stay in sync with the active node, so it makes sense that the updates would come directly from the active node using bloxSync. I'll go with option C.

Hmm, I'm a little confused on the difference between SSL VPN and bloxSync. I'll have to review my notes to make sure I understand the correct mechanism for how the passive node gets its updates. Maybe I'll eliminate the SSL VPN options first.

Okay, I remember learning about this in class. The passive node receives the database updates via bloxSync, but it's coming from the Active node, not the Grid Master. I'm confident that C is the right answer here.

I'm a bit unsure about this one. Is the passive node getting the updates directly from the active node, or is it going through the Grid Master? I'll have to think this through carefully.

Hmm, this seems like a pretty straightforward question about how the passive node in an HA pair receives database updates. I think I'll go with option C - bloxSync from the Active node.

Hmm, I'm going with D) bloxSync from the Grid Master. Seems like the most reliable option, unless the Grid Master is running on a hamster wheel.
