Cisco 400-007 Exam - Topic 4 Question 70 Discussion

You were tasked to enhance the security of a network with these characteristics:* A pool of servers is accessed by numerous data centers and remote sites* The servers are accessed via a cluster of firewalls* The firewalls are configured properly and are not dropping traffic* The firewalls occasionally cause asymmetric routing of traffic within the server data center.Which technology should you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstation and redirecting flows at the servers?
C) Limit sources of traffic that exit the server-facing interface of the firewall cluster with ACLs.
A) Poison certain subnets by adding static routes to Null0 on the core switches connected to the pool of servers.
B) Deploy uRPF strict mode.
D) Deploy uRPF loose mode

Poisoning subnets sounds risky, but I recall it being a method to manage routing issues. I wonder if it would really enhance security in this scenario.

I think limiting sources with ACLs could be effective, especially since it directly controls what can exit the firewall. I practiced a similar question on that.

I remember studying about uRPF, but I'm not entirely sure if strict mode is the right choice here. It seems like it could help with asymmetric routing, though.

I'm feeling pretty confident about this one. Limiting the sources with ACLs is definitely the way to go to lock down that server pool and prevent potential hacker traffic.

Okay, I think I've got it. The key is to limit the traffic sources on the firewall cluster to prevent any redirected flows from reaching the servers. ACLs seem like the way to go here to enhance the security.

Poison the subnets? I don't know, that sounds a bit risky. I'd be worried about accidentally blocking legitimate traffic. The ACL approach seems safer and more targeted.
