In Cisco SD-WAN architecture, the vBond Orchestrator plays a crucial role in the initial device onboarding and control plane security. Ensuring redundancy for vBond Orchestrators is essential for maintaining high availability and reliability in the SD-WAN network.
1.Fully Qualified Domain Name (FQDN): The use of an FQDN is a key element in vBond Orchestrator redundancy. By configuring multiple vBond Orchestrators with the same FQDN, the SD-WAN devices can resolve this domain name to different IP addresses corresponding to the different vBond Orchestrator instances. This allows for automatic failover and load balancing among the vBond Orchestrators.
1.Redundancy Mechanism: The DNS mechanism will resolve the FQDN to a list of IP addresses, and in case one vBond is unreachable, another can be contacted. This approach ensures continuous availability and redundancy without requiring manual reconfiguration of the devices.

DHCP server? Not even close!

Yeah, load-balancer is the way to go!

Definitely a load-balancer with health probes!

I don't think a DHCP server is relevant here, but I can't remember if a stun server plays any role in vBond redundancy.

I practiced a similar question, and I feel like the health probes are crucial for maintaining redundancy, but I could be mixing it up with another topic.

I remember something about fully qualified domain names being important in network configurations, but I can't recall if it's specifically for vBond.

I think the redundancy topology might involve a load-balancer with health probes, but I'm not entirely sure.

Okay, let me see... A fully qualified domain name doesn't seem relevant for redundancy. DHCP and STUN servers also don't sound like the right answer here. I'm leaning towards C, the load-balancer with health probes, but I'm not 100% sure.

Hmm, I'm not too familiar with vBond Orchestrator redundancy. I'll have to think this through carefully and review my notes before answering.

This question seems pretty straightforward. I think the answer is C - a load-balancer with health probes would be a key element in a vBond Orchestrator redundancy topology.

I've got this one! The key element in a vBond Orchestrator redundancy topology is a load-balancer with health probes. That makes perfect sense to ensure high availability and failover. C is the answer.

Hmm, this seems tricky. I'm a bit confused about how the search head cluster and deployer work in this case. I'll need to review the Splunk documentation to make sure I understand the implications of the power user's dashboard modification.

The characteristics point towards a compound instrument, right? I feel like we covered something similar in our last review session.

Haha, A) fully qualified domain name? I mean, sure, that's important, but it's not the 'key element' for redundancy. Nice try, exam writer!

B) DHCP server? Nah, that's just for IP address assignment. Gotta be something more specific to the vBond redundancy.

D) stun server? Really? That doesn't sound right at all. This is more about the network infrastructure, not VoIP protocols.
