Question 440
A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.
Explanation
Correct Answers
Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. This control addresses the failure mechanism and narrows the enforcement boundary. Phishing harvests authentication material; contextual verification and phishing-resistant authenticators reduce credential replay risk without proving all messages are safe. Confirm pre-change conditions using: Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. This is the implementation portion of the complementary pair. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.
Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. This checks the relevant condition before an engineer modifies production access or detection behavior. Phishing harvests authentication material; contextual verification and phishing-resistant authenticators reduce credential replay risk without proving all messages are safe. The controlled response would be: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. This supplies the diagnostic evidence needed for the complementary action. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.

Inspect embedding source sets, package provenance, vector index tenant filters, model artifacts, and integrity-check history. This step could matter for Embedding and model supply chain risk but is not part of the required complementary pair for this case. The paired steps are: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. and Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.
Protected traffic crosses the tunnel with authenticated peers and encrypted data even behind the intended NAT device. This step could matter for IPsec IKE and NAT traversal but is not part of the required complementary pair for this case. The paired steps are: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. and Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.
Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment. This step could matter for DDoS versus endpoint malware diagnosis but is not part of the required complementary pair for this case. The paired steps are: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. and Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.
