Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if the data exists in the cache.

Azure

if cache.[1](key):

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

Aexists

Bcontains

Cget

Dhas_key

💡 Hint

Common Mistakes

Using 'get' instead of a method that checks existence.

Using 'contains' which is not a valid method here.

The exists method checks if the key exists in the cache.

2fill in blank

medium

Complete the code to retrieve data from the cache.

Azure

data = cache.[1](key)

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

Aget

Bfetch

Cretrieve

Dload

💡 Hint

Common Mistakes

Using 'fetch' or 'retrieve' which are not valid cache methods.

Using 'load' which is not a cache method.

The get method retrieves the value for the given key from the cache.

3fill in blank

hard

Fix the error in the code to store data in the cache.

Azure

cache.[1](key, data, expiration=3600)

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

Astore

Bsave

Cset

Dput

💡 Hint

Common Mistakes

Using 'store' or 'put' which are not valid Azure Cache methods.

Using 'save' which is not a cache method.

The set method stores data in the cache with an optional expiration time.

4fill in blank

hard

Fill both blanks to implement cache-aside pattern: fetch from cache or load from database.

Azure

if not cache.[1](key):
    data = database.[2](key)
    cache.set(key, data)

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

Ahas_key

Bfetch

Cget

Dload

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'get' in first blank which retrieves data but does not check existence.

Using 'fetch' for database which is not the method here.

First, check if the key exists in cache with exists. If not, load data from database using load.

5fill in blank

hard

Fill all three blanks to complete cache-aside pattern with expiration time.

Azure

if not cache.[1](key):
    data = database.[2](key)
    cache.[3](key, data, expiration=300)

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

Ahas_key

Bload

Cset

Dget

Attempts:

💡 Hint

Common Mistakes

Using 'get' instead of 'exists' to check existence.

Using 'fetch' instead of 'load' for database.

Using 'save' instead of 'set' to store cache.

Check cache key existence with exists, load data from database with load, then store in cache with set including expiration.
