| Question | Answer |
|---|---|
| Function together as a dynamic array, using at least 2 load balancers to distribute traffic and cache requests for enhanced efficiency. Operate close to max capacity | Active/Active load balancer configuration |
| Includes one active (actively balances incoming requests) and one passive load balancer (on standby mode) in case one node fails | Active/Passive load balancer configuration |
| Involves grouping multiple servers or nodes together to operate as a single system, an d has one active and passive node that share a common quorum disk | Clustering |
| A shared storage resource, acting as a neutral authority, storing critical configuration and state information that both active and passive nodes access | Quorum Disk |
| Non-bias entity that helps determine the state of the cluster, prevents split-brain, and ensures that the cluster operates smoothly | Witness Server |
| Communication between the active and passive nodes is facilitated through a ___ mechanism. | Heartbeat |
| Ensures that if one node fails, the cluster remains accessible without disruption. Additionally, it acts as the entry point for external requests (public facing interface) | Virtual IP (VIP) |
| Type of site best for rapid recovery, fully operational, and its immediate response capability makes these sites the most expensive to maintain, but fastest to recover from downtime. | Hot Site |
| Data may be sent via courier or other means, resulting in a 3-4 hour delay. Its fully functional, but data synchronization typically lags slightly. | Warm Site |
| Provides essential infrastructure, such as water and power but lacks staff, equipment, and data. The lack of pre-loaded data and operational readiness makes this type of site the slowest option to get up and running in a disaster scenario. | Cold Site |
| What is the goal of geographic dispersion? | Enhance resilience by reducing the risk of a single point of failure, mitigating the impact of natural disasters. |
| 3 copies of data replicated within a single physical location or data center. Offers basic redundancy but not suitable for high-availability situations | Local Redundant Storage (LRS) |
| 3 copies of data within a single physical location or data center, but also stores one copy in a secondary region | GEO Redundant Storage (GRS) |
| Copies data between 3 separate availability zones within the primary region and one copy to a secondary region | GEO Zone Redundant Storage (GZRS) |
| Resilience and redundancy is an essential feature of Continuity of Operations (COOP) and its goal is ___ | reduce single points of failure |
| Involves the assessment, optimization, and alignment of the workforce to meet current and future needs | Capacity planning for people |
| Involves equipping the right tools and resources to meet evolving demands, such as resource scalability, hardware and software upgrades, security and compliance, and innovation and emerging tech | Capacity planning for technology |
| Involves ensuring that physical assets align with its evolving needs, such as facility expansion and optimization, energy efficiency, and disaster recovery | Capacity planning for infrastructure |
| Enable seamless transfer of operations to backup systems or data centers in the event of a system failure or disruption | Failover |
| Often deployed in a distributed computing environment, enhances resilience by enabling multiple processes to work simultaneously, and ensures that if one component fails, operations can seamlessly transition to alternative resources | Parallel processing |
| Suitable for organizations with limited storage resources, and backs up changes in data since the last full backup or the last incremental backup | Incremental backup |
| Grow progressively larger each day, but you only need 2 tapes for the backup, the initial full backup and the latest differential backup | Differential backup |
| Type of backup vulnerable to hardware failures or local disasters, but quick data retrieval, and involves storing copies of essential data within the physical premises | On-site backup |
| Copies of virtual machines frozen at a specific point in time, acting like time machines, enabling you to return to that exact state if something goes wrong | Snapshots |
| Like cloned data, creates a duplicate set of info in real time, which is typically used to send data to a cloud-based backup solution or a hot site | Replication |
| Meticulously records when files are created, edited, or removed, along with the specifics of these changes | Journaling |
| Electrical device that provides backup power to connected equipment or devices during power outages, and is designed to keep the system going for only a FEW MINUTES | Uninterruptible Power Supply (UPS) |
| Serve as a frontline defense, providing controlled power distribution to servers and networking equipment, ensuring efficient power management and protection against overloads, and can be used to monitor power consumption | Power Distribution Units (PDUs) |
| Informs stakeholders discreetly during incidents, ensuring effective communication without alerting the public, and outlines who needs to be informed, when and how, as well as what privacy procedures should be implemented. | Communication Plan |
