Evaluate the two proposed answers. Which are supported? I. Malicious software recording keystrokes — the suitable term or action: Keylogger. II. An attacker pretending to be a trusted sender — the suitable term or action: Keylogger.
Correct answer: D
I is correct: Malicious software recording keystrokes → Keylogger. It can capture passwords and other typed information. II is incorrect: An attacker pretending to be a trusted sender → Spoofing. The apparent identity or source is falsified.
For Malware disguised as useful software, identify the suitable term or action.
Correct answer: C
The deceptive appearance encourages installation or execution.
Evaluate the two proposed answers. Which are supported? I. Sharing a one-time password with an unsolicited caller — the suitable term or action: Physical access protection. II. One-way digest used for integrity checking — the suitable term or action: Offline backup.
Correct answer: A
I is incorrect: Sharing a one-time password with an unsolicited caller → Unsafe credential disclosure. An OTP can authorise access or transactions. II is incorrect: One-way digest used for integrity checking → Cryptographic hash. A secure hash is not intended to be reversed into the original message.
For Using one password across many services, identify the suitable term or action.
Correct answer: D
A breach at one service can endanger other accounts.
Evaluate the two proposed answers. Which are supported? I. Repeated attempts using many possible passwords — the suitable term or action: Password reuse. II. Malware disguised as useful software — the suitable term or action: Trojan.
Correct answer: A
I is incorrect: Repeated attempts using many possible passwords → Brute-force attack. Rate limits and strong authentication can reduce exposure. II is correct: Malware disguised as useful software → Trojan. The deceptive appearance encourages installation or execution.
Evaluate the two proposed answers. Which are supported? I. Using one password across many services — the suitable term or action: Encryption. II. One-way digest used for integrity checking — the suitable term or action: Cryptographic hash.
Correct answer: C
I is incorrect: Using one password across many services → Password reuse. A breach at one service can endanger other accounts. II is correct: One-way digest used for integrity checking → Cryptographic hash. A secure hash is not intended to be reversed into the original message.
Evaluate the two proposed answers. Which are supported? I. Database column — the appropriate concept: Reference linking a record to a key in another table. II. Database query — the appropriate concept: Request to retrieve or manipulate data.
Correct answer: C
I is incorrect: Database column → Field or attribute. It stores one kind of information across records. II is correct: Database query → Request to retrieve or manipulate data. A query can select records by conditions.
For Flowchart decision symbol, identify the appropriate concept.
Correct answer: B
A diamond conventionally represents branching on a condition.
Evaluate the two proposed answers. Which are supported? I. Boolean value — the appropriate concept: True or false. II. Algorithm — the appropriate concept: Finite sequence of steps for solving a problem.
Correct answer: A
I is correct: Boolean value → True or false. Boolean expressions are used in logical tests. II is correct: Algorithm → Finite sequence of steps for solving a problem. An algorithm is independent of a particular programming language.
For SQL SELECT, identify the appropriate concept.
Correct answer: B
It can specify columns, tables and conditions.
Evaluate the two proposed answers. Which are supported? I. Compiler — the appropriate concept: Translator from source code into another executable or lower-level form. II. Database column — the appropriate concept: Field or attribute.
Correct answer: A
I is correct: Compiler → Translator from source code into another executable or lower-level form. Compilation differs from merely editing text. II is correct: Database column → Field or attribute. It stores one kind of information across records.
For Foreign key, identify the appropriate concept.
Correct answer: C
It supports relationships and referential integrity.
Evaluate the two proposed answers. Which are supported? I. Loop — the appropriate concept: Execution path selected by a test. II. Variable — the appropriate concept: Tracking changes and versions of files.
Correct answer: A
I is incorrect: Loop → Repeated execution of instructions. A loop continues according to a count or condition. II is incorrect: Variable → Named storage or reference for a value. Its value can change during program execution where the language permits.
For Conditional branch, identify the appropriate concept.
Correct answer: C
An if statement is a common example.
Evaluate the two proposed answers. Which are supported? I. Database query — the appropriate concept: Request to retrieve or manipulate data. II. SQL SELECT — the appropriate concept: Statement used to retrieve data.
Correct answer: B
I is correct: Database query → Request to retrieve or manipulate data. A query can select records by conditions. II is correct: SQL SELECT → Statement used to retrieve data. It can specify columns, tables and conditions.
For Boolean value, identify the appropriate concept.
Correct answer: A
Boolean expressions are used in logical tests.
Evaluate the two proposed answers. Which are supported? I. Foreign key — the appropriate concept: Reference linking a record to a key in another table. II. Compiler — the appropriate concept: Translator from source code into another executable or lower-level form.
Correct answer: B
I is correct: Foreign key → Reference linking a record to a key in another table. It supports relationships and referential integrity. II is correct: Compiler → Translator from source code into another executable or lower-level form. Compilation differs from merely editing text.
Evaluate the two proposed answers. Which are supported? I. Flowchart decision symbol — the appropriate concept: Repeated execution of instructions. II. SQL WHERE — the appropriate concept: Finite sequence of steps for solving a problem.
Correct answer: C
I is incorrect: Flowchart decision symbol → Diamond. A diamond conventionally represents branching on a condition. II is incorrect: SQL WHERE → Clause filtering rows by a condition. It limits which rows satisfy a query.
For Database column, identify the appropriate concept.
Correct answer: A
It stores one kind of information across records.
Evaluate the two proposed answers. Which are supported? I. Foreign key — the appropriate concept: Statement used to retrieve data. II. Conditional branch — the appropriate concept: Execution path selected by a test.
Correct answer: C
I is incorrect: Foreign key → Reference linking a record to a key in another table. It supports relationships and referential integrity. II is correct: Conditional branch → Execution path selected by a test. An if statement is a common example.
For Debugging, identify the appropriate concept.
Correct answer: B
A syntax-correct program can still contain logical bugs.
Evaluate the two proposed answers. Which are supported? I. Database column — the appropriate concept: Reference linking a record to a key in another table. II. Loop — the appropriate concept: Translator from source code into another executable or lower-level form.
Correct answer: C
I is incorrect: Database column → Field or attribute. It stores one kind of information across records. II is incorrect: Loop → Repeated execution of instructions. A loop continues according to a count or condition.
For SQL WHERE, identify the appropriate concept.
Correct answer: B
It limits which rows satisfy a query.
Evaluate the two proposed answers. Which are supported? I. Version control — the appropriate concept: Tracking changes and versions of files. II. Flowchart decision symbol — the appropriate concept: True or false.
Correct answer: D
I is correct: Version control → Tracking changes and versions of files. It supports comparison, collaboration and recovery of earlier states. II is incorrect: Flowchart decision symbol → Diamond. A diamond conventionally represents branching on a condition.
