Common Mistakes

Choosing 'manual' which slows down recovery and backups.

Cloud offers high availability, automatic backups, and fast recovery, ensuring your data and services stay accessible.

Practice

1. Why do many businesses choose cloud computing over on-premises servers?

easy

A. Because on-premises servers are always faster

B. Because cloud lets them avoid buying and managing physical servers

C. Because cloud requires more physical space

D. Because on-premises servers are cheaper to maintain

Solution

1. Step 1: Understand cost and management differences

   On-premises servers need buying, setup, and ongoing management which costs time and money.

2. Step 2: Compare with cloud benefits

   Cloud removes the need to buy physical servers and handles management, saving money and effort.

3. Final Answer:

   Because cloud lets them avoid buying and managing physical servers -> Option B

4. Quick Check:

   Cloud saves money and effort [OK]

Hint: Cloud avoids physical server costs and management [OK]

Common Mistakes:

• Thinking on-premises is always cheaper
• Confusing physical space needs
• Assuming cloud is slower

2. Which of the following is a correct reason to prefer cloud over on-premises?

easy

A. Cloud allows easy scaling to match your needs anytime

B. On-premises servers can be accessed from anywhere without internet

C. Cloud needs you to buy more hardware

D. On-premises servers automatically update without manual work

Solution

1. Step 1: Review cloud scaling feature

   Cloud lets you increase or decrease resources quickly as your needs change.

2. Step 2: Check other options for accuracy

   Options A, B, and D are incorrect because cloud does not require buying hardware, on-premises needs internet for remote access, and updates often require manual effort.

3. Final Answer:

   Cloud allows easy scaling to match your needs anytime -> Option A

4. Quick Check:

   Cloud scaling [OK]

Hint: Cloud scales resources easily anytime [OK]

Common Mistakes:

• Thinking cloud needs more hardware
• Believing on-premises is internet-free for remote access
• Assuming on-premises updates are automatic

3. Consider this scenario: A company uses cloud services and suddenly needs more storage. What happens next?

medium

A. They need to wait weeks for hardware delivery

B. They must buy new physical hard drives and install them

C. They can quickly increase storage through the cloud provider's console

D. They have to shut down services to add storage

Solution

1. Step 1: Understand cloud resource flexibility

   Cloud providers allow users to add resources like storage instantly via online tools.

2. Step 2: Contrast with on-premises process

   On-premises requires buying and installing hardware, which takes time and may need downtime.

3. Final Answer:

   They can quickly increase storage through the cloud provider's console -> Option C

4. Quick Check:

   Cloud quick resource increase [OK]

Hint: Cloud storage scales fast via console [OK]

Common Mistakes:

• Confusing cloud with physical hardware buying
• Assuming downtime is needed for cloud scaling
• Thinking cloud scaling takes weeks

4. A company tries to access their on-premises server remotely but fails. What is a likely cause?

medium

A. They need to buy more physical servers

B. Cloud services do not allow remote access

C. On-premises servers always allow remote access by default

D. They forgot to connect the server to the internet

Solution

1. Step 1: Identify remote access requirements

   On-premises servers need proper internet connection and configuration to be accessed remotely.

2. Step 2: Evaluate options for correctness

   They forgot to connect the server to the internet correctly points to missing internet connection; B and C are false statements; A is unrelated to access issues.

3. Final Answer:

   They forgot to connect the server to the internet -> Option D

4. Quick Check:

   Remote access needs internet [OK]

Hint: Remote access needs internet connection [OK]

Common Mistakes:

• Thinking cloud disallows remote access
• Assuming on-premises remote access is automatic
• Confusing hardware purchase with access issues

5. A startup wants to launch a website that might get very popular suddenly. Why is cloud a better choice than on-premises for this?

hard

A. Cloud can automatically scale resources up or down based on traffic

B. On-premises servers handle sudden traffic spikes better

C. Cloud requires buying extra servers in advance

D. On-premises servers are easier to access from anywhere

Solution

1. Step 1: Understand traffic scaling needs

   A sudden increase in website visitors needs quick resource scaling to avoid slowdowns or crashes.

2. Step 2: Compare cloud and on-premises scaling

   Cloud can automatically adjust resources instantly; on-premises needs manual hardware changes which are slow and costly.

3. Step 3: Eliminate incorrect options

   Options B, C, and D are incorrect because on-premises is less flexible, cloud does not require buying extra servers upfront, and cloud access is easier.

4. Final Answer:

   Cloud can automatically scale resources up or down based on traffic -> Option A

5. Quick Check:

   Cloud auto-scaling fits sudden traffic [OK]

Hint: Cloud auto-scales for traffic spikes [OK]

Common Mistakes:

• Believing on-premises handles spikes better
• Thinking cloud needs pre-bought servers
• Confusing access ease between cloud and on-premises
