What is the primary purpose of a Content Delivery Network (CDN)?

To increase the speed and reliability of content delivery to users.

To manage user authentication and authorization.

To perform complex data analytics on user behavior.

In a Push CDN model, how is content typically delivered to the edge servers?

The CDN proactively pushes content from the origin server to its edge servers.

Users actively request content from the origin server, which then forwards it to the CDN.

Content is downloaded from a central repository by the edge servers when needed.

Content is streamed directly from the origin server to users without intermediate caching.

Which of the following are advantages of using a Push CDN model?

Faster initial deployment of new content to edge servers.

Better handling of sudden traffic spikes for newly updated content.

Reduced control over content freshness on edge servers.

Potentially higher storage costs at the origin.

What is a potential disadvantage of a Push CDN?

Content might become stale on edge servers if not updated frequently.

Increased latency for users accessing content.

Higher bandwidth costs for the origin server.

Limited geographic distribution of content.

Consider a scenario where a popular video streaming service wants to ensure that its latest blockbuster movie is available to users worldwide with minimal buffering. Which CDN model would be most suitable for this scenario and why?

Push CDN, because the content can be pre-loaded onto edge servers before release.

Pull CDN, because users will request the content as needed.

Hybrid CDN, because it offers a balance of control and on-demand delivery.

Static CDN, because video content is considered static.

When deciding between a Push CDN and a Pull CDN, which factor is LEAST likely to be a primary consideration for a website with frequently changing news articles?

The volume of static assets like images and CSS.

The need for real-time content updates.

The cost of storage at the origin.

The frequency of content updates.

What are the key differences between Push and Pull CDN models regarding content management?

In Push CDN, the content owner proactively sends content to the CDN. In Pull CDN, the CDN fetches content upon user request.

In Push CDN, the CDN provider manages content updates. In Pull CDN, the content owner does.

Push CDN is used for dynamic content, while Pull CDN is for static content.

Push CDN requires direct user interaction with the origin server, while Pull CDN does not.

Which of the following scenarios would benefit MOST from a Push CDN strategy?

A government website with critical, time-sensitive emergency alerts.

A music streaming service releasing a new album.

A personal blog with infrequent updates.

A large e-commerce site with millions of products that are updated daily.

How does a Push CDN contribute to improving application performance and user experience?

By reducing the number of network hops and latency through edge caching.

By always fetching content directly from the origin server.

By increasing the distance between the user and the content.

By relying solely on user-initiated content downloads.

What are the implications of choosing a Push CDN for content that changes very frequently, such as live sports scores?

It might lead to a significant delay between the actual score change and its appearance on user devices.

It requires a complex infrastructure for continuous content updates to the edge servers.

It is an ideal solution because the scores can be pushed in real-time.

It is generally not suitable for highly dynamic or real-time data.
