ICC1 End of Week Quiz

A popular online retail company experiences significant spikes in website traffic during holiday sales events and Black Friday, followed by periods of much lower activity. To ensure their website remains responsive and available during peak demand without incurring excessive costs during off-peak times, they utilise a cloud solution that can automatically adjust its computing resources. What is the primary benefit of this cloud computing characteristic?

• It enables multiple users to access the same application simultaneously

• It allows resources to be automatically scaled up or down based on demand

• It provides backup and disaster recovery capabilities

• It ensures data is encrypted during transmission and storage

Your company is deploying a critical, highly available application in Azure. To protect your application from datacenter-level failures within an Azure region, you should deploy your resources across multiple physically separate locations with independent power, cooling, and networking. Which Azure concept provides this level of fault isolation within an Azure region?

• Resource Groups

• Availability Sets

• Virtual Networks (VNets)

• Availability Zones

For a medium-sized company extending its on-premises network to Azure, requiring secure, cost-effective connectivity over the public internet without needing dedicated bandwidth or the lowest latency, which Azure networking service is best?

• Azure ExpressRoute

• Azure Load Balancer

• Azure Virtual Network (VNet)

• Azure VPN Gateway

You have an Azure Virtual Network (VNet) containing several virtual machines. You need to control inbound and outbound network traffic to these virtual machines based on IP address, port, and protocol. Which Azure networking service should you use to achieve this?

• Azure Load Balancer

• Azure VPN Gateway

• Azure Network Security Group (NSG)

• Azure Application Gateway

A new start-up is launching its first product, which includes a marketing website that they anticipate will experience fluctuating and unpredictable visitor traffic. Their small team wants to focus primarily on product development rather than infrastructure management, so they need a solution that minimises operational overheads, handles scaling automatically, and supports rapid deployment of their simple web application. Which Azure compute service would be MOST appropriate for their needs?

• Azure Container Instances

• Azure Virtual Machines

• Azure Kubernetes Service

• Azure App Service

A global enterprise runs mission-critical applications in Azure and needs to ensure that their services remain available even if an entire Azure region experiences a major disaster. They implement a strategy where their applications and data are replicated to a geographically separate location within the same geopolitical boundary. What is the primary purpose of this design choice, leveraging Azure Region Pairs?

• To provide disaster recovery and business continuity

• To share computing resources between regions

• To enable cross-region authentication

• To reduce latency between regions

A small development team is storing non-critical test data in Azure Blob Storage. They need to ensure data durability against typical disk drive failures within a single physical location, but they are looking for the lowest possible cost and do not require protection against a regional disaster or an entire data centre outage. Which Azure storage redundancy option would be most appropriate for their needs?

• LRS

• ZRS

• GRS

• GZRS

A database server experiences a notable degradation in performance due to an escalating workload that strains its existing processing power and memory resources. To mitigate this bottleneck and accommodate the increased demand, an administrator undertakes the action of upgrading the server's capabilities by integrating additional CPUs and expanding its RAM. This particular approach to scaling computational resources exemplifies what?

• Horizontal scaling

• Vertical scaling

• Auto-scaling

• Elastic scaling

A rapidly growing start-up decides to adopt a cloud-first strategy for its IT infrastructure, aiming to minimise large upfront investments and manage costs based on actual usage. Instead of purchasing and maintaining physical servers and software licences, they opt for readily available services hosted by a third-party cloud provider. In this cloud computing environment, which of the following would be categorised as an Operational Expenditure (OpEx) for the company?

• The purchase of a new server rack for a data centre

• A monthly subscription for a SaaS accounting software

• The upfront cost of custom-built data centre infrastructure

• Investing in new cooling systems for an on-premises server room

CapCorp Manufacturing Co keeps sensitive R&D data on-premises due to strict regulations but uses a public cloud for its e-commerce platform to handle unpredictable traffic and leverage scalability. This strategic integration of both environments is an example of which cloud deployment model?

• Public Cloud

• Private Cloud

• Hybrid Cloud

• Multi-Cloud
