Microsoft Azure Solutions Architect Expert AZ-305 Flashcards
| Front | Back |
| Define Disaster Recovery | The process of restoring critical systems and data after a failure or disaster. |
| Define Fault Tolerance | The ability of a system to continue operating despite failures or errors. |
| Define Recovery Point Objective (RPO) | The maximum amount of data loss allowed during a recovery scenario. |
| Describe Azure Managed Disks' role in high availability | Provides durable, scalable storage with built-in redundancies for improved resilience. |
| Describe Azure Traffic Manager | A tool for directing traffic to optimal endpoints to ensure resilience and performance. |
| Describe the concept of Business Continuity Planning | Ensuring operations can continue during and after a disruption. |
| Describe the importance of encrypting backups | Protects sensitive data from unauthorized access during storage and recovery. |
| Describe the use of Azure Blob Storage for backups | Provides scalable, secure, and cost-efficient storage for backup data. |
| Explain Azure Auto-scaling | Automatically adjusts resources based on demand to maintain performance and availability. |
| Explain Azure Backup Service | A cost-effective, scalable solution to prepare backups and restore data in Azure environments. |
| Explain Geo-Redundancy in Azure | Storing and replicating data in multiple locations to ensure accessibility during regional failures. |
| Explain the concept of Load Balancing in high availability solutions | Distributing traffic across multiple resources to optimize performance and ensure service availability. |
| Explain the importance of Multi-Region Disaster Recovery Strategies | Reduces risk by ensuring services can failover to geographically diverse regions. |
| Explain the role of database mirroring in disaster recovery | Ensures continuous database availability by maintaining synchronous copies. |
| What are Azure Availability Zones? | Physically separate datacenters within a region offering high availability and redundancy. |
| What are the benefits of Azure Site Recovery? | It provides disaster recovery by replicating workloads to different regions for fast recovery. |
| What is a Failover in disaster recovery? | Switching to a redundant or standby system when the primary system fails. |
| What is Application Gateway in Azure? | A load balancer that improves availability and security of web applications. |
| What is Azure Shared Responsibility Model? | Clarifies the responsibilities between Azure and customers in securing and maintaining solutions. |
| What is High Availability in cloud solutions? | Ensuring applications and databases remain accessible with minimal downtime. |
| What is the purpose of a Disaster Recovery Plan | A detailed strategy outlining procedures to restore operations after a disruption. |
| What is the purpose of a testing schedule for disaster recovery? | Ensures plans and systems are effective and can be reliably implemented during crises. |
| What is the purpose of hot and cold data storage in Azure? | Hot storage provides immediate access, while cold storage is for infrequent access at lower costs. |
| What is the Recovery Time Objective (RTO)? | The maximum acceptable time to restore a system after a disruption. |
| What is the role of VM backups in business continuity? | Ensures virtual machines can be restored quickly in case of failure or disaster. |
| What is the significance of monitoring and alerting in business continuity solutions? | Proactively identifies issues to minimize downtime and maintain system health. |
| Why is data replication essential for business continuity? | It ensures copies of data are available in case of corruption or loss. |
| Why is network redundancy important in high availability? | It eliminates single points of failure and maintains connectivity during outages. |
| Why use Azure ExpressRoute for business continuity? | Provides reliable and fast connections between on-premises environments and Azure. |
| Why use Incremental Backups? | They back up only changes since the last backup, saving storage and time. |
This deck addresses disaster recovery, backup strategies, and high availability solutions to ensure Azure-based architectures remain resilient to disruptions.
