Practice Questions

Q1. A user writes an e-mail in a mail client while the Internet connection is unavailable. What generally happens when the user clicks Send in offline mode?

A The mail is delivered immediately because SMTP does not require a network connection.
B The mail is kept in an outbox or local queue and sent when the client reconnects to the mail server. Correct
C The mail is converted into a web page and published automatically.
D The mail is permanently deleted because offline messaging never stores drafts or outgoing mail.

Explanation

Online messaging requires an active network path to the service or mail server. Offline-capable mail clients can still let the user compose a message and place it in an outbox or queue. Actual transfer through protocols such as SMTP happens after the client regains connectivity.

Q2. Which option correctly matches a common multimedia or graphics file type with its usual use?

A TXT for compressed photographic images on a web gallery
B SVG for scalable vector graphics and JPEG for compressed photographs Correct
C EXE for embedding vector graphics directly in an HTML image tag
D CSV for live audio compression in voice mail

Explanation

Multimedia files are chosen according to the media type and required quality. Vector formats such as SVG suit scalable diagrams and icons, while JPEG is commonly used for photographic images where lossy compression can reduce file size.

Q3. Which example best illustrates offline messaging in contrast to online real-time messaging?

A A user composes a message while disconnected and the application sends it when connectivity returns. Correct
B A video meeting is started so every participant can see and hear one another live.
C A browser refreshes a web page every second to show stock prices.
D Both users must remain connected at the same time and type replies instantly.

Explanation

Online messaging expects active connectivity and often near-real-time delivery. Offline messaging stores or queues the message locally or on a server so that it can be sent or received later when the user or network becomes available.

Q4. In the normal operation of a search engine, which sequence best describes how a newly published public web page becomes searchable?

A The web server converts the page into XML, and the search engine automatically accepts its ranking.
B The browser cache alone submits the page directly to the payment gateway.
C The page owner emails the page to every user, and the browser stores it permanently.
D A crawler discovers the URL, the page is processed for indexing, and ranking systems later serve relevant results. Correct

Explanation

A search service discovers pages through crawling, stores and processes discovered information in an index, and uses ranking systems when a user enters a query. Files such as robots.txt can influence crawling access, while noindex is used when a page should be kept out of the index.

Q5. Which example is the clearest case of business-to-consumer e-commerce?

A An online retailer accepting an order from an individual customer through its website Correct
B A router translating a private IP address into a public IP address
C A DNS server returning the IP address for a domain name
D A browser saving a page in offline reading mode

Explanation

E-commerce concerns the sale or purchase of goods or services through computer networks. In B2C e-commerce, the seller is a business and the buyer is an individual consumer, as in a retail website taking a customer's order.
