Cisco 350-901 Exam - Topic 12 Question 45 Discussion

Two Elasticsearch database servers use bidirectional asynchronous data replication Both servers accept writes from clients The design must meet these requirements:* The cluster must survive if a fault occurs that causes the network connection to go down between nodes* The data must remain consistent if communication between nodes fails.* The data must be spread evenly across all nodes in the cluster.Which design approach must be used to meet the requirements?
C) Set the minimum_master_nodes to 2 in the configuration.
A) Set the initial voting configuration to force a specific node as the master.
B) Scale the master nodes down to a single node.
D) Add a third cluster node to provide majority votes.

I feel like A could lead to issues if the master fails.

C seems solid too, but not sure if it covers all the requirements.

Wait, can you really scale down to one master node? Sounds risky!

Definitely agree with D, more nodes = better fault tolerance!

I think option D is the best choice for majority votes.

I’m a bit confused about the voting configurations. I thought forcing a specific node as master could lead to issues if that node fails, but I can't remember the details.

I practiced a similar question where we had to ensure data consistency, and I feel like setting minimum_master_nodes to 2 might be the right choice here.

I think adding a third node could help with majority votes, but I can't recall if that directly addresses the consistency issue when nodes can't communicate.

I remember discussing how having a minimum of two master nodes can help with fault tolerance, but I'm not sure if that's enough for this scenario.

I'm a little confused by the "configure manual binding" option. I'm not sure if that's something I need to set up for a standard DHCP server, or if that's a more advanced configuration. I'll have to research that one a bit more.

Okay, let me see here. The first option talks about real-time monitoring and immediate promotion of busy pages. That sounds like it could be correct. The second option mentions enabling Active Flash on any HDT pool with SSD or FMD drives in Tier 1, which also seems plausible.

Ooh, this is a tough call. I'm not sure if I'd want to bring in someone from the accounting department, even if they're not involved. That could get messy. I think I'd go with option C and get a fraud expert consultant to handle it.

Alright, let's break this down. Lookup, stored procedure, and external procedure seem like the most likely unconnected combination here. I'm going to go with A and hope I'm right.
