What is the Circuit Breaker design pattern used for in cloud architecture?
Answer: Preventing cascading failures by temporarily blocking requests to a failing service and allowing recovery time
The Circuit Breaker pattern monitors for failures in remote service calls and 'opens the circuit' to stop sending requests when failures exceed a threshold, preventing cascading failures.
Which Azure storage option provides the highest throughput for high-performance computing (HPC) workloads?
Answer: Azure NetApp Files or Azure Managed Lustre
Azure NetApp Files and Azure Managed Lustre provide high-performance NFS/SMB file storage optimized for HPC, AI training, and media rendering workloads requiring ultra-low latency.
What is the purpose of an Azure Application Gateway?
Answer: A Layer 7 web application load balancer with SSL termination, URL-based routing, and optional WAF
Azure Application Gateway is a Layer 7 load balancer that routes HTTP/S traffic based on URL paths or hostnames, with SSL offloading and an optional Web Application Firewall.
In a hub-spoke network topology in Azure, what is the purpose of the hub VNet?
Answer: Centralizing shared services like VPN gateway, firewall, and DNS that spoke VNets connect to via peering
The hub VNet in a hub-spoke topology centralizes shared network services like VPN gateways, Azure Firewall, and DNS servers that multiple spoke VNets consume via peering.
What is the difference between Recovery Time Objective (RTO) and Recovery Point Objective (RPO)?
Answer: RTO is the maximum acceptable downtime to restore service; RPO is the maximum acceptable data loss measured in time
RTO defines how quickly a system must be restored after a failure (downtime tolerance), while RPO defines how much data loss is acceptable (last backup age tolerance).
What is Azure Private Endpoint used for?
Answer: Connecting to Azure PaaS services over a private IP within your VNet, eliminating public internet exposure
Azure Private Endpoint assigns a private IP address from your VNet to Azure PaaS services like Storage or SQL, so all traffic stays on the Microsoft backbone without traversing the public internet.
