Understanding Azure CDN Profiles

Which statement best describes the purpose of an Azure CDN profile?

A It groups multiple CDN endpoints under a single management scope and billing account.

B It stores the cached content delivered by the CDN to end users.

C It is the configuration for a single domain name used by the CDN.

D It defines the geographic locations where CDN nodes are deployed.

💡 Hint

Think about how Azure organizes CDN resources for billing and management.

An Azure CDN profile acts as a container for multiple CDN endpoints, allowing centralized management and billing. It does not store content or define node locations directly.

Azure CDN Endpoint Configuration

You want to deliver static website content globally using Azure CDN. Which component must you create to specify the origin server for your content?

A Azure CDN endpoint

B Azure CDN profile

C Azure CDN custom domain

D Azure CDN caching rule

💡 Hint

Consider which part connects the CDN to your source content.

The Azure CDN endpoint defines the origin server URL from which the CDN pulls content to cache and deliver to users.

Scaling Azure CDN for High Traffic

Your website experiences sudden spikes in traffic worldwide. Which Azure CDN feature helps ensure low latency and high availability during these spikes?

A Multiple CDN profiles with separate billing

B Using multiple CDN endpoints within a profile to distribute load

C Configuring a single CDN endpoint with a custom domain

D Enabling geo-filtering to restrict traffic

💡 Hint

Think about how to distribute traffic load efficiently.

Using multiple CDN endpoints within a profile allows traffic to be distributed across endpoints, improving load handling and availability during spikes.

❓ tradeoff

Choosing Between CDN Providers in Azure

Azure CDN supports multiple providers like Verizon and Microsoft. What is a key tradeoff when selecting a CDN provider for your Azure CDN profile?

A Verizon CDN provides advanced security features but may have higher latency in some regions.

B Microsoft CDN offers more global POPs but less integration with Azure services.

C Choosing a provider affects pricing, feature set, and geographic coverage.

D All providers offer identical features and pricing, so choice is irrelevant.

💡 Hint

Consider differences in cost, features, and coverage.

Each CDN provider has unique pricing, features, and geographic reach, so selecting one involves balancing these factors based on your needs.

Estimating Azure CDN Endpoint Capacity

You expect 10 million requests per day globally with an average response size of 500 KB. Approximately how much data transfer (in TB) will your Azure CDN endpoint handle daily?

A About 0.5 TB

B About 50 TB

C About 500 TB

D About 5 TB

💡 Hint

Calculate total bytes transferred: requests × size, then convert to TB (1 TB = 10^12 bytes).

10 million requests × 500 KB = 5,000,000,000 KB = 5,000,000,000,000 bytes = 5 TB.
