Why scalability handles growing traffic in HLD - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define scalability as the system's ability to handle {{BLANK_1}} traffic.

HLD

Scalability means a system can handle [1] traffic without performance loss.

💡 Hint

Common Mistakes

Choosing constant traffic, which does not reflect growth.

Scalability is about handling growing traffic smoothly.

2fill in blank

medium

Complete the code to show that scalability can be achieved by adding more {{BLANK_1}}.

HLD

To improve scalability, we add more [1] to distribute the load.

💡 Hint

Common Mistakes

Choosing users or errors, which do not help handle traffic.

Adding more servers helps distribute traffic and improve scalability.

3fill in blank

hard

Fix the error in the statement about scalability: 'Scalability means the system can handle {{BLANK_1}} traffic by adding a single server.'

HLD

Scalability means the system can handle [1] traffic by adding a single server.

Cgrowing

Drandom

💡 Hint

Common Mistakes

Choosing constant or decreasing traffic, which do not reflect scalability.

Scalability is about handling growing traffic, not just constant or decreasing.

4fill in blank

hard

Fill both blanks to complete the scalability strategy: 'Use {{BLANK_1}} to balance load and {{BLANK_2}} to add capacity.'

HLD

Use [1] to balance load and [2] to add capacity.

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing caches or databases which do not directly add capacity or balance load.

Load balancers distribute traffic, and more servers increase capacity for scalability.

5fill in blank

hard

Fill all three blanks to complete the scalability explanation: 'Scalability involves {{BLANK_1}} servers, {{BLANK_2}} data storage, and {{BLANK_3}} traffic efficiently.'

HLD

Scalability involves [1] servers, [2] data storage, and [3] traffic efficiently.

Cbalancing

Dreducing

💡 Hint

Common Mistakes

Choosing reducing, which is opposite of scalability goals.

Scalability means adding servers, distributing data storage, and balancing traffic efficiently.
