Evaluate the two proposed answers. Which are supported? I. IP address — the function or meaning: Logical address used in Internet Protocol communication. II. Web browser — the function or meaning: Small piece of site-related data stored by a client.
Correct answer: D
I is correct: IP address → Logical address used in Internet Protocol communication. It helps identify a network interface for packet delivery. II is incorrect: Web browser → Client software for retrieving and displaying web content. It interprets web documents for the user.
For Latency, identify the function or meaning.
Correct answer: C
A high-capacity link can still have high latency.
Evaluate the two proposed answers. Which are supported? I. DHCP — the function or meaning: Automatically supplies network configuration. II. Router — the function or meaning: Forwards packets between networks.
Correct answer: B
I is correct: DHCP → Automatically supplies network configuration. It can assign IP addresses and related settings. II is correct: Router → Forwards packets between networks. It chooses paths using routing information.
Evaluate the two proposed answers. Which are supported? I. Web browser — the function or meaning: Data-carrying capacity of a communication channel. II. TCP — the function or meaning: Reliable ordered transport protocol.
Correct answer: D
I is incorrect: Web browser → Client software for retrieving and displaying web content. It interprets web documents for the user. II is correct: TCP → Reliable ordered transport protocol. It uses acknowledgements and retransmission.
For Modem, identify the function or meaning.
Correct answer: C
Its name derives from modulation and demodulation.
Evaluate the two proposed answers. Which are supported? I. IP address — the function or meaning: Logical address used in Internet Protocol communication. II. MAC address — the function or meaning: Link-layer hardware interface identifier.
Correct answer: C
I is correct: IP address → Logical address used in Internet Protocol communication. It helps identify a network interface for packet delivery. II is correct: MAC address → Link-layer hardware interface identifier. It is used on local network segments.
For IP address, identify the function or meaning.
Correct answer: A
It helps identify a network interface for packet delivery.
Evaluate the two proposed answers. Which are supported? I. Latency — the function or meaning: Forwards packets between networks. II. Packet switching — the function or meaning: Forwards packets between networks.
Correct answer: B
I is incorrect: Latency → Delay before or during delivery of data. A high-capacity link can still have high latency. II is incorrect: Packet switching → Dividing data into packets for network transmission. Packets can be routed over shared links.
Evaluate the two proposed answers. Which are supported? I. Spreadsheet calculation beginning with an equals sign — the appropriate feature: COUNTIF. II. Text repeated at the top of printed pages — the appropriate feature: Header.
Correct answer: B
I is incorrect: Spreadsheet calculation beginning with an equals sign → Formula. The expression computes a result from values or references. II is correct: Text repeated at the top of printed pages → Header. Headers are separate from ordinary body paragraphs.
For Sending personalised letters from one template and an address list, identify the appropriate feature.
Correct answer: D
It combines a document with structured recipient data.
Evaluate the two proposed answers. Which are supported? I. Showing the relationship between two numeric variables — the appropriate feature: Scatter plot. II. Restricting cell entry to allowed values — the appropriate feature: Conditional formatting.
Correct answer: A
I is correct: Showing the relationship between two numeric variables → Scatter plot. Each point represents an x-y pair. II is incorrect: Restricting cell entry to allowed values → Data validation. It can provide a dropdown and reject invalid entries.
For Keeping a row visible while scrolling, identify the appropriate feature.
Correct answer: D
It changes the view without duplicating the row's data.
Evaluate the two proposed answers. Which are supported? I. Displaying change through time — the appropriate feature: Styles. II. Adding values that meet one condition — the appropriate feature: SUMIF.
Correct answer: C
I is incorrect: Displaying change through time → Line chart. Connected observations emphasise temporal trends. II is correct: Adding values that meet one condition → SUMIF. It sums entries satisfying a criterion.
For Starting content at the top of a new page, identify the appropriate feature.
Correct answer: D
It is more reliable than inserting many blank paragraphs.
Evaluate the two proposed answers. Which are supported? I. Text repeated at the top of printed pages — the appropriate feature: Header. II. Sending personalised letters from one template and an address list — the appropriate feature: Mail merge.
Correct answer: C
I is correct: Text repeated at the top of printed pages → Header. Headers are separate from ordinary body paragraphs. II is correct: Sending personalised letters from one template and an address list → Mail merge. It combines a document with structured recipient data.
For Showing the relationship between two numeric variables, identify the appropriate feature.
Correct answer: B
Each point represents an x-y pair.
Evaluate the two proposed answers. Which are supported? I. Spreadsheet calculation beginning with an equals sign — the appropriate feature: Formula. II. Keeping a row visible while scrolling — the appropriate feature: Line chart.
Correct answer: D
I is correct: Spreadsheet calculation beginning with an equals sign → Formula. The expression computes a result from values or references. II is incorrect: Keeping a row visible while scrolling → Freeze panes. It changes the view without duplicating the row's data.
For Restricting cell entry to allowed values, identify the appropriate feature.
Correct answer: B
It can provide a dropdown and reject invalid entries.
Evaluate the two proposed answers. Which are supported? I. Repeating identical formatting in a document — the appropriate feature: Styles. II. Counting cells that meet one condition — the appropriate feature: COUNTIF.
Correct answer: C
I is correct: Repeating identical formatting in a document → Styles. Styles provide consistent reusable formatting rules. II is correct: Counting cells that meet one condition → COUNTIF. It counts matching cells rather than adding their values.
For Text repeated at the top of printed pages, identify the appropriate feature.
Correct answer: B
Headers are separate from ordinary body paragraphs.
