An engineer must build redundancy into the network and traffic must continuously flow if a redundant switch in front of the firewall goes down. What must be configured to accomplish this task?
To ensure network redundancy and continuous traffic flow even if a redundant switch in front of the firewall goes down, utilizing a Virtual Port Channel (vPC) on the switches connected to the span EtherChannel on the firewall cluster is effective. vPC allows for the connection of multiple switches to operate as a single entity, which enables load balancing and redundancy by distributing traffic across multiple links. This setup ensures that if one link or switch fails, the traffic can still flow through the other available links without interruption.
The answer is correct: Virtual Port Channels (vPC) are common EtherChannel deployments, especially in the data center, and allow multiple devices to share multiple interfaces EtherChannel Interface requires stack, VSS or vPC when connected to multiple switches
Answer A seems perfectly fine to me. I dont trust answer D because it's unintelligible. Answer A seems to say the same thing as answer D anyhow.
I am with you. Answer A. first vPC - this can be done by VSS, Virtual StackWise, etc.... any clustering techniques can be used. For me, A is more general cover
When you place the cluster in your network, the upstream and downstream routers need to be able to load-balance the data coming to and from the cluster using Spanned EtherChannels. Interfaces on multiple members of the cluster are grouped into a single EtherChannel; the EtherChannel performs load balancing between units.
Answer is D https://www.cisco.com/c/en/us/td/docs/security/firepower/fxos/clustering/asa-cluster-solution.html#:~:text=Virtual%20Port%20Channel%20(vPC
D is correct.
Answer: D
Correct answer is (D), since EtherChannel with vPC utilize all for this connection dedicated firewall interfaces simultaniously. Redundant interface configurations are getting out-dated in present times due to the disadvantage of only utilizing one instead of 2 interfaces that belong to the SLA monitor setup.
Option A, which involves creating redundant interfaces on the firewall in cluster mode and on the switches, does provide redundancy. However, it is not as specific and comprehensive as option D for ensuring continuous traffic flow in the context of the problem described. Using Virtual Port Channel (vPC) on the switches to the span EtherChannel on the firewall cluster (option D) is specifically designed to provide both redundancy and load balancing. This method ensures that links from both switches are seen as a single port channel by the firewall cluster, allowing for seamless failover and continuous traffic flow even if one switch fails. So while option A addresses redundancy, it does not explicitly mention the configuration techniques (vPC and Spanned EtherChannel) that are best suited to achieve the desired outcome of uninterrupted traffic flow
