Difficulty: MediumCategorical Classification and Sorting

An enterprise cybersecurity team categorizes software patch deployment tasks into four priority tiers (Tier 1: Highest Priority to Tier 4: Lowest Priority) based on two criteria:

1. Exposure Risk: Public-Facing or Internal-Only
2. Threat Severity: Critical, High, or Moderate

The prioritization rules are defined as follows:
- Tier 1: Public-Facing and Critical Severity
- Tier 2: Public-Facing and High Severity, OR Internal-Only and Critical Severity
- Tier 3: Public-Facing and Moderate Severity, OR Internal-Only and High Severity
- Tier 4: Internal-Only and Moderate Severity

Four upcoming deployment tasks are described below:
- Patch Alpha: Public-Facing system with Critical Severity
- Patch Beta: Internal-Only system with Critical Severity
- Patch Gamma: Public-Facing system with Moderate Severity
- Patch Delta: Internal-Only system with Moderate Severity

Which of the following represents the correct sequence of deployment tasks ordered from highest priority (1st) to lowest priority (4th)?

  1. 1Patch Alpha (Public-Facing, Critical Severity)
  2. 2Patch Beta (Internal-Only, Critical Severity)
  3. 3Patch Gamma (Public-Facing, Moderate Severity)
  4. 4Patch Delta (Internal-Only, Moderate Severity)

Answer

The correct order from highest priority to lowest priority is Patch Alpha, Patch Beta, Patch Gamma, and Patch Delta.
To determine the correct priority sequence, each deployment task must be evaluated against the tier assignment rules. Patch Alpha (Public-Facing, Critical) meets the Tier 1 conditions. Patch Beta (Internal-Only, Critical) fits Tier 2. Patch Gamma (Public-Facing, Moderate) fits Tier 3. Patch Delta (Internal-Only, Moderate) fits Tier 4. Sorting from Tier 1 to Tier 4 yields the sequence: Patch Alpha, Patch Beta, Patch Gamma, Patch Delta.

Step-by-Step Solution

1
Evaluate Patch Alpha against the classification rules.
Patch Alpha has Public-Facing exposure and Critical severity, assigning it to Tier 1.
Tier 1 explicitly requires Public-Facing exposure and Critical severity.
2
Evaluate Patch Beta against the classification rules.
Patch Beta has Internal-Only exposure and Critical severity, assigning it to Tier 2.
Tier 2 includes Internal-Only systems with Critical severity.
3
Evaluate Patch Gamma against the classification rules.
Patch Gamma has Public-Facing exposure and Moderate severity, assigning it to Tier 3.
Tier 3 includes Public-Facing systems with Moderate severity.
4
Evaluate Patch Delta against the classification rules.
Patch Delta has Internal-Only exposure and Moderate severity, assigning it to Tier 4.
Tier 4 includes Internal-Only systems with Moderate severity.
5
Order the patches from Tier 1 (Highest) to Tier 4 (Lowest).
The sequence is Tier 1 (Patch Alpha) → Tier 2 (Patch Beta) → Tier 3 (Patch Gamma) → Tier 4 (Patch Delta).
Ranking tiers numerically from 1 to 4 establishes the correct priority order.
