Not sure about D. RSTP is good, but doesn't really solve the capacity issue.

Option B seems solid. More interfaces mean more capacity.

I feel like option A could work too. Splitting VLANs might help.

I think option C is the best. Port channels balance the load.

Wait, why would we enable RSTP? That doesn't really solve the capacity issue.

Adding more interfaces to R1 and R2 could help balance the load.

D) RSTP is for redundancy, not load balancing. That won't solve the problem.

C) Configure port channel toward downstream switches. This will improve load balancing and utilize all the available bandwidth.

Enabling RSTP seems like it could help with redundancy, but I don't see how it directly addresses the capacity issue.

I'm leaning towards configuring a port channel since it can aggregate bandwidth, but I need to double-check if that's the best option here.

I remember studying HSRP, but I'm not sure if making R2 active for half the VLANs would really balance the load effectively.

Making R2 active for half the VLANs could work, but that feels a bit hacky to me. I'd prefer a more elegant, scalable solution if possible. The port channel idea is probably the way to go.

I'm not totally sure about the RSTP option. Wouldn't that be more focused on redundancy and failover rather than load balancing? I'd want to double-check the details on that one before selecting it.

Okay, I think I've got this. The key is to find a way to more evenly distribute the traffic across the available interfaces. Option C about configuring a port channel seems like the most straightforward solution to me.

I'm a bit confused by the wording of the question. Is it asking about improving the load balancing specifically, or just generally improving the network capacity? I'll need to read it carefully to make sure I understand the core issue.

Hmm, this looks like a classic HSRP load balancing question. I'd start by considering the current utilization of the downstream interfaces and think about how to better distribute the load.
