Exam SY0-701 topic 1 question 42 discussion

When designing a high-availability network, two key considerations are: A. Ease of recovery D. Responsiveness - Ease of recovery. This is essential for high availability because the network must be able to recover quickly from failures to minimize downtime. - Responsiveness. Ensuring that the network can handle high traffic loads and respond quickly to user requests is crucial for maintaining high availability. Other factors like physical isolation, ability to patch, attack surface, and extensible authentication are important for security and maintenance but are not primary considerations for high availability. Therefore, the correct answers are: A. Ease of recovery D. Responsiveness

A. Ease of Recovery and C. Physical Isolation

bad wording again. is this about high availability/resiliency or redundancy? A suggests redundancy C suggests redundancy D suggests resilience Question is asking about resiliency so, it looks like the only reasonable answer is D. Both A and C should not be correct. so, it would seem they are asking about redundancy, not resiliency in which case we get A and C good job again compTIA

The Answer should be A: Ease of recovery and C: Physical isolation. -I know that the answer says A and D, but think about it, responsiveness is built upon a working system, and If a single point of failure occurs, then responsiveness will mean nothing. The question asks what "must" be considered for availability, so A: Ease of recovery minimizes downtime and increases availability, and C: Physical isolation eliminates a single point of failure and provides availability. -Even though responsiveness is also important, it is still built upon a working system, and if a single point of failure occurs, then responsiveness will not matter.

High availability focuses on redundancy, fault tolerance, and recovery mechanisms rather than just speed. The more correct answers remain Ease of recovery and Physical isolation, as they directly impact the ability of a network to remain operational despite failures.

A & D Ease of recovery/Responsiveness

Prof Messer's video explains it well.

Think of doing an online purchase. Which would minimally affect your transaction? Which shortens system downtime?

I was pretty confident about AD at first. However, availability focuses on minimizing downtime and ensuring continuous operation. Physical Isolation provides redundancy and protection against failures, which is a fundamental aspect of high availability, ensuring that issues in one part of the network do not impact the overall availability of services. Physical isolation helps prevent a single point of failure from affecting the entire network. While responsiveness is important for performance, it is not specifically a high-availability consideration. High availability focuses on ensuring that systems remain operational and recover quickly from failures, rather than optimizing performance.

A. Ease of recovery High availability requires systems to recover quickly and easily in case of failure. This ensures minimal downtime and fast restoration of services. D. Responsiveness A high-availability network must respond quickly to changes or failures to maintain uptime. This includes quick failover mechanisms and the ability to rapidly address network issues.

When designing a high-availability network, two key considerations are: Ease of recovery: This refers to the network’s ability to quickly and efficiently recover from failures or disruptions. Having redundant components, failover mechanisms, and well-defined recovery procedures in place is crucial1. Physical isolation: Ensuring that critical components are physically separated helps prevent single points of failure and enhances network resilience.

A & D A. Ease of Recovery, ensure quick restoration after a failure. D. Responsiveness, ensures the network can handle the load and maintain availability

High-availability networks require robust recovery processes to ensure that services can be restored rapidly after any failure, minimizing the impact on users and maintaining service continuity. Responsiveness is crucial for a high-availability network, as it ensures that the network can handle unexpected changes and continue delivering services efficiently, even under stress or during failures.

Ease of recovery = HA Ability to patch = security Physical isolation = HA (because nobody can touch it) Responsiveness = Performance Attack surface = Security Extensible authentication = Security

Why not A and E? Its a tuff question.

A. Ease of recovery D. Responsiveness
