Evaluate the two proposed answers. Which are supported? I. Keeping a disconnected copy of important data — the suitable term or action: Offline backup. II. Self-replicating malware spreading across networks — the suitable term or action: Worm.
Correct answer: C
I is correct: Keeping a disconnected copy of important data → Offline backup. It may remain protected if connected systems are compromised. II is correct: Self-replicating malware spreading across networks → Worm. It can propagate without attaching to a separate host file.
For Verifying a login through a second independent factor, identify the suitable term or action.
Correct answer: B
A second password alone is not a distinct factor type.
Evaluate the two proposed answers. Which are supported? I. One-way digest used for integrity checking — the suitable term or action: Cryptographic hash. II. Locking a workstation when leaving it — the suitable term or action: Physical access protection.
Correct answer: A
I is correct: One-way digest used for integrity checking → Cryptographic hash. A secure hash is not intended to be reversed into the original message. II is correct: Locking a workstation when leaving it → Physical access protection. It reduces unauthorised use of an unattended session.
For Repeated attempts using many possible passwords, identify the suitable term or action.
Correct answer: B
Rate limits and strong authentication can reduce exposure.
Evaluate the two proposed answers. Which are supported? I. Sharing a one-time password with an unsolicited caller — the suitable term or action: Spoofing. II. Checking a suspicious link's destination before opening — the suitable term or action: Phishing risk reduction.
Correct answer: D
I is incorrect: Sharing a one-time password with an unsolicited caller → Unsafe credential disclosure. An OTP can authorise access or transactions. II is correct: Checking a suspicious link's destination before opening → Phishing risk reduction. The visible link text can differ from its actual target.
For Self-replicating malware spreading across networks, identify the suitable term or action.
Correct answer: C
It can propagate without attaching to a separate host file.
Evaluate the two proposed answers. Which are supported? I. An attacker pretending to be a trusted sender — the suitable term or action: Spoofing. II. Applying a vendor fix for a known vulnerability — the suitable term or action: Multi-factor authentication.
Correct answer: A
I is correct: An attacker pretending to be a trusted sender → Spoofing. The apparent identity or source is falsified. II is incorrect: Applying a vendor fix for a known vulnerability → Patching. Updates can remove exploitable defects.
For Converting readable data into ciphertext using a key, identify the suitable term or action.
Correct answer: B
Authorised decryption requires the appropriate key.
Evaluate the two proposed answers. Which are supported? I. One-way digest used for integrity checking — the suitable term or action: Patching. II. Granting only access needed for a task — the suitable term or action: Patching.
Correct answer: C
I is incorrect: One-way digest used for integrity checking → Cryptographic hash. A secure hash is not intended to be reversed into the original message. II is incorrect: Granting only access needed for a task → Least privilege. Reducing unnecessary privileges limits potential damage.
For Malicious software recording keystrokes, identify the suitable term or action.
Correct answer: A
It can capture passwords and other typed information.
Evaluate the two proposed answers. Which are supported? I. Verifying a login through a second independent factor — the suitable term or action: Phishing risk reduction. II. Self-replicating malware spreading across networks — the suitable term or action: Brute-force attack.
Correct answer: D
I is incorrect: Verifying a login through a second independent factor → Multi-factor authentication. A second password alone is not a distinct factor type. II is incorrect: Self-replicating malware spreading across networks → Worm. It can propagate without attaching to a separate host file.
For Sharing a one-time password with an unsolicited caller, identify the suitable term or action.
Correct answer: B
An OTP can authorise access or transactions.
Evaluate the two proposed answers. Which are supported? I. Keeping a disconnected copy of important data — the suitable term or action: Offline backup. II. Locking a workstation when leaving it — the suitable term or action: Trojan.
Correct answer: C
I is correct: Keeping a disconnected copy of important data → Offline backup. It may remain protected if connected systems are compromised. II is incorrect: Locking a workstation when leaving it → Physical access protection. It reduces unauthorised use of an unattended session.
For Applying a vendor fix for a known vulnerability, identify the suitable term or action.
Correct answer: B
Updates can remove exploitable defects.
Evaluate the two proposed answers. Which are supported? I. Converting readable data into ciphertext using a key — the suitable term or action: Encryption. II. Malicious software recording keystrokes — the suitable term or action: Keylogger.
Correct answer: A
I is correct: Converting readable data into ciphertext using a key → Encryption. Authorised decryption requires the appropriate key. II is correct: Malicious software recording keystrokes → Keylogger. It can capture passwords and other typed information.
For Granting only access needed for a task, identify the suitable term or action.
Correct answer: B
Reducing unnecessary privileges limits potential damage.

For An attacker pretending to be a trusted sender, identify the suitable term or action.
Correct answer: A
The apparent identity or source is falsified.
Evaluate the two proposed answers. Which are supported? I. Converting readable data into ciphertext using a key — the suitable term or action: Cryptographic hash. II. Malware disguised as useful software — the suitable term or action: Trojan.
Correct answer: D
I is incorrect: Converting readable data into ciphertext using a key → Encryption. Authorised decryption requires the appropriate key. II is correct: Malware disguised as useful software → Trojan. The deceptive appearance encourages installation or execution.
For Locking a workstation when leaving it, identify the suitable term or action.
Correct answer: C
It reduces unauthorised use of an unattended session.
Evaluate the two proposed answers. Which are supported? I. Using one password across many services — the suitable term or action: Password reuse. II. Checking a suspicious link's destination before opening — the suitable term or action: Phishing risk reduction.
Correct answer: A
I is correct: Using one password across many services → Password reuse. A breach at one service can endanger other accounts. II is correct: Checking a suspicious link's destination before opening → Phishing risk reduction. The visible link text can differ from its actual target.
