CDN Setup & Cloud Admin Configuration

1. What does 'Time-to-Live' (TTL) specify in CDN caching?

How long content is stored on edge servers before refresh

The maximum number of users allowed

The server's uptime duration

The network latency threshold

2. What is 'failover' in CDN high-availability configuration?

Automatic redirection to backup servers when primary fails

Reducing content delivery speed

Blocking international users

Increasing data storage requirements

3. Which monitoring tool helps track CDN performance analytics?

Origin server log files only

CDN provider dashboard and real-time reporting tools

User browser cache

Network router configuration

4. What is the benefit of 'compression' in CDN optimization?

Reduces file size for faster transmission

Encrypts content for security

Increases cache capacity

Improves server processing power

5. How do CDNs handle 'cache misses' when content is not available?

Return an error to the user immediately

Fetch content from origin server and store it

Redirect to a competitor's CDN

Block the user's request

6. What is 'origin shielding' in advanced CDN architecture?

An intermediate caching layer between edge nodes and origin

Firewall protection for the CDN provider

User authentication mechanism

Data encryption standard

7. Which type of content benefits most from CDN distribution?

Real-time database transactions

Static assets like images, CSS, and JavaScript

Sensitive user credentials

Internal configuration files

8. What is 'token-based authentication' used for in CDN security?

Verifying authorized users before serving content

Encrypting all network traffic

Monitoring server performance

Backing up cached data

9. Which metric helps measure CDN effectiveness for end users?

Origin server CPU utilization

Page load time and latency reduction

Total data center size

Number of edge servers deployed

10. In CDN configuration, what is the purpose of 'purging' content?

Removing specific cached content immediately

Increasing server memory allocation

Blocking user IP addresses

Backing up origin server data

11. What is the primary function of a Content Delivery Network (CDN)?

Store all data in a single centralized location

Distribute content across geographically dispersed servers to reduce latency

Encrypt all data in transit

Monitor network traffic for security threats

12. Which protocol is typically used for secure CDN communication?

HTTP/1.0

HTTPS/TLS

FTP

Telnet

13. What is 'cache hit ratio' in CDN performance metrics?

The percentage of requests served from cache

The total number of users accessing content

The average response time in milliseconds

The amount of bandwidth consumed

14. Which of the following is a security benefit of using a CDN?

Hides the origin server's IP address

Automatically patches all vulnerabilities

Eliminates the need for firewalls

Prevents all DDoS attacks permanently

15. How does geographic routing in a CDN improve performance?

It encrypts content based on location

It directs users to the nearest edge server

It blocks international traffic

It increases bandwidth costs

16. What is the purpose of a CDN's 'origin server'?

Store copies of content at edge locations

Serve as the authoritative source of content

Monitor all user requests

Encrypt all outbound traffic

17. Which HTTP header is commonly used to control CDN caching behavior?

Content-Type

Cache-Control

User-Agent

Accept-Encoding

18. In CDN terminology, what is 'cache invalidation'?

Removing outdated content from edge servers

Deleting user session data

Blocking unauthorized access attempts

Reducing server CPU usage

19. What does the term 'edge node' refer to in CDN architecture?

The main data center storing all content

A server located close to end users for faster content delivery

A firewall protecting the origin server

The network interface card in a server

20. Which of the following is a key advantage of using a CDN for static content delivery?

Reduced origin server load and improved user experience

Automatic database replication

Enhanced application logic processing

Unlimited storage capacity
