You need to configure the routing for your Virtual Private Cloud (VPC). Your design must meet the following requirements:All access to your on-premises network must go through the network virtual appliances.Allow on-premises access in the event of a single network virtual appliance failure.Both network virtual appliances must be used simultaneously.Which method should you use to accomplish this?
B) Configure an internal HTTP(S) load balancer with the two network virtual appliances as backends. Configure a route for 10.0.0.0/8 with the internal HTTP(S) load balancer as the next hop.
A) Configure two routes for 10.0.0.0/8 with different priorities, each pointing to separate network virtual appliances.
C) Configure a network load balancer for the two network virtual appliances. Configure a route for 10.0.0.0/8 with the network load balancer as the next hop.
D) Configure an internal TCP/UDP load balancer with the two network virtual appliances as backends. Configure a route for 10.0.0.0/8 with the internal load balancer as the next hop.

Wait, can both appliances really be used at the same time?

I’m not so sure about B, what if the load balancer fails too?

I’m leaning towards option D, but I’m a bit uncertain about whether the TCP/UDP load balancer is the best fit for routing traffic to the appliances.

I feel like I came across a similar question where we had to ensure redundancy. I wonder if prioritizing routes would really meet the requirements here.

I think option C with the network load balancer sounds familiar. It might be the right choice since it can handle both appliances simultaneously.

I remember studying about load balancers, but I'm not sure if I should use an HTTP(S) or TCP/UDP one for this scenario.

This is a good question to test our understanding of CDN functionality. I'm pretty confident that the correct answers are B and D, as those options describe how to directly access the visitor's real IP address through the HTTP headers and CDN logs, respectively.

I'm a bit confused by the question. The exhibit doesn't seem to provide much detail about the network topology or the specific issues being experienced. I'll need to re-read the question carefully and try to understand the context better.

I remember something about employer ownership not being a common aspect of HSAs, so maybe that's the correct answer.

I remember practicing a similar question, and I think DMVPN was the right answer there, but this feels different.
