Q1
Which unit is storage usually priced in?
A. Per request
B. Per GB-month
C. Per hour of machine time
D. Per GB moved
Show answer
Correct: B. Storage is priced per gigabyte kept for a month. Per GB moved is for data transfer, and per hour is for rented machines.
Q2
Requests cost an illustrative $0.40 per million. A service makes 30 million requests in a month. What is the cost?
A. $1.20
B. $120
C. $0.40
D. $12
Show answer
Correct: D. 30 million is 30 lots of one million. 30 x $0.40 = $12.
Q3
What is the general rule for data transfer?
A. Data in is usually free; data out is usually charged per GB
B. Data in and out are always both free
C. Data in is charged per GB; data out is free in every case
D. Only data stored for over a year is charged
Show answer
Correct: A. Providers make it free to bring data in and charge for data going out, especially to the internet.
Q4
A machine is stopped but not deleted. Which charge usually continues?
A. The full hourly charge for the machine
B. A charge for every request it used to receive
C. The charge for its attached disk
D. Nothing at all
Show answer
Correct: C. Stopping ends the compute charge, but the disk still holds data and bills per GB-month until it is deleted.
Q5
On Azure, what must you do for a stopped machine to stop its compute charge?
A. Shut it down from inside its operating system
B. Stop (deallocate) it from the Azure portal or tools
C. Disconnect it from the internet
D. Remove its disk but leave the machine running
Show answer
Correct: B. Shutting down from inside the operating system leaves an Azure machine “Stopped” but still allocated, and still charged for compute. Stopping it from the portal deallocates it.
Q6
A snapshot is:
A. A screenshot of the cloud console
B. A summary of last month’s bill, saved as a file for finance
C. A short burst of extra machine power
D. A saved copy of a disk at one moment, billed per GB-month
Show answer
Correct: D. Snapshots are disk copies kept for restoring later. They bill per GB-month and can outlive the machine they came from.
Q7
Which data movement is usually the most expensive per GB?
A. Out from the cloud to the internet
B. Into the cloud from the internet
C. Between two resources in the same zone
D. Within a single machine’s own disk
Show answer
Correct: A. Egress to the internet is usually the priciest. Ingress and same-zone traffic are usually free, and a machine reading its own disk is not data transfer at all.
Q8
A NAT gateway is charged:
A. Never; it is always included free
B. Only once, when it is created
C. By the hour, plus for each GB that passes through it
D. Only for data coming into the cloud through the gateway
Show answer
Correct: C. NAT gateways have an hourly charge and a per-GB processing charge, which is why traffic going out through one can be charged twice.
Q9
What are on-demand prices?
A. Discounted prices for a three-year promise
B. Prices for spare machines that can be taken back
C. Prices that change every hour with demand
D. Pay-as-you-go prices with no long-term promise
Show answer
Correct: D. On-demand is the published, pay-as-you-go price. A describes commitments and B describes spot capacity.
Q10
A team picks the cheapest region for its customer website, far from its customers. What is the most likely downside?
A. The website cannot store any data
B. Customers get slower responses, and data rules may be broken
C. The provider will refuse to run it
D. The machines will be smaller than the size that was ordered
Show answer
Correct: B. Distance adds delay, and some data must stay in a particular place by law or contract. Price is one factor in choosing a region, not the only one.
