Exam N10-008 topic 1 question 278 discussion

An HA pair is a group of two firewalls that are configured to work together to provide high availability and failover protection. If one firewall becomes unavailable, the other firewall can take over and continue providing network services. This can help to decrease latency during periods of high utilization because the workload is distributed across two firewalls rather than being handled by a single device.

Saw the same question without NIC teaming on the choices. So go with HA pair on this one

Which of the following can be used to DECRECE latency DURING periods of high utilization of a firewall?

The option that can be used to decrease latency during periods of high utilization of a firewall is C. HA pair. An HA (High Availability) pair involves two firewalls that are configured to work together to provide increased availability and reliability. If one firewall becomes overloaded or fails, the other can take over its duties, helping to ensure that network traffic continues to flow smoothly and latency is minimized.

Not all third-party hardware or software, such as switches, drivers, or firewalls, may work on NIC teaming

i think its c, the key word is during, ie if be happens then what will kick in

To decrease latency during periods of high utilization of a firewall, B. NIC teaming (Network Interface Controller teaming) is a common solution. Explanation: NIC teaming combines multiple network interfaces on the firewall into a single logical interface to increase bandwidth and fault tolerance. During high utilization, NIC teaming allows the firewall to distribute network traffic across multiple physical interfaces, reducing the risk of congestion and lowering latency.

B. NIC teaming reduces load and bandwidth. HA pair from How I understand is more like a failover or redundancy. If one fails, the other takes over

Both B and C are correct; they both can decrease the latancy by increasing the throughput. It depends on the company badge.

One of the possible ways to decrease latency during periods of high utilization of a firewall is to use NIC teaming. NIC (Network Interface Card) teaming is a technology that allows multiple network interfaces to function as a single, aggregated interface. By using NIC teaming, a network technician can increase the bandwidth and redundancy of the firewall, as well as balance the network traffic across multiple interfaces. This can improve the performance and reliability of the firewall and reduce the latency caused by congestion or bottlenecks.

Old mate ChatGPT: Option C, "HA pair," can be used to decrease latency during periods of high utilization of a firewall. An HA (high availability) pair is a configuration in which two firewalls are set up to work together in a redundant and fail-safe manner. The primary firewall processes all traffic, while the secondary firewall monitors the primary and takes over its responsibilities in case of failure or downtime. During periods of high utilization, the primary firewall may become overwhelmed and cause latency in processing traffic. However, with an HA pair configuration, the secondary firewall can take over some of the traffic processing duties to reduce the load on the primary firewall and decrease latency. This solution helps to ensure that traffic continues to flow smoothly and without delay, even during periods of high utilization or when the primary firewall experiences issues.

C. HA pair in "active-active" mode(both or multiple firewalls are online at the same time) and not "active-passive" mode(the rest wait for an failure to happen, then goes online). https://www.checkpoint.com/cyber-hub/network-security/what-is-firewall/high-availability-ha-firewall/#:~:text=What%20is%20a%20High%20Availability,a%20group%20as%20a%20cluster.

NIC teaming can be used to decrease latency during periods of high utilization of a firewall. NIC (Network Interface Card) teaming is a technology that allows multiple network interfaces to function as a single, aggregated interface. By combining multiple physical interfaces, NIC teaming can increase network throughput and reduce latency during periods of high network traffic. This can help to improve the performance of a firewall during times of high utilization. Hot site, HA (High Availability) pair, and VRRP (Virtual Router Redundancy Protocol) are all technologies designed to improve network availability and reliability, but they do not specifically address latency during periods of high utilization.

C - HA Pair (I think) HA pairs can be configured in Active-Active, or Active-Passive, both of which are on the exam objectives. Like others have said, NIC Teaming is where a single piece of equipment has two network cards which could, in theory, connect to two Firewalls but the questions appears to be worded towards the Firewall part of the connection, rather than a single piece of equipment with two paths to the Firewall, which is why I think it's a HA Pair of Firewalls (I hope that made sense...)

At peak times, when the available bandwidth would otherwise be saturated (leading to increased latency), NIC teaming could provide greater bandwidth and thus mitigate the issue. A HA pair could, in a loadbalancing arrangement, could also help, but only in an active-active setup - which is not what is explicitly specified here. I follow the principle to only question the answers provided, if there is a strong reason to do so. I don't see this here.

C. HA pair is Correct.

A. Hot site cannot be used to decrease latency during periods of high utilization of a firewall. B. NIC teaming refers to the aggregation of multiple network adapters into a single logical interface to increase network performance. This can improve network performance, but will not decrease latency during periods of high utilization of a firewall. C. HA (High Availability) pair refers to two firewalls that are configured to provide failover capability in the event that one of the firewalls fails. This can provide continuous firewall protection and reduce downtime, but will not decrease latency during periods of high utilization of a firewall. D. VRRP (Virtual Router Redundancy Protocol) is a protocol used to provide automatic failover of the default gateway in the event of a failure. This can improve network reliability, but will not decrease latency during periods of high utilization of a firewall. Therefore, none of the above options would be used to decrease latency during periods of high utilization of a firewall.
