Detailed Answer in Step-by-Step Solution:

Objective: Identify the non-Observability and Management (O&M) service in OCI.

Understand O&M: Includes monitoring, logging, events tools.

Evaluate Options:

A: Event Services—Triggers actions, part of O&M—correct.

B: OCI Management Service—Not a defined O&M service—incorrect.

C: Logging Analytics—Log analysis, O&M component—correct.

D: Logging—Log collection, O&M component—correct.

Reasoning: B isn’t listed in OCI’s O&M suite—others are.

Conclusion: B is correct (not part of O&M).

OCI documentation lists “Observability and Management Services as including Event Services (A), Logging Analytics (C), and Logging (D)—‘OCI Management Service’ (B) is not a recognized component.” B appears to be a misnomer—only A, C, D are O&M per OCI’s service catalog.

Detailed Answer in Step-by-Step Solution:

Objective: Identify IAM components in OCI.

Understand IAM: Manages access via policies, groups, etc.

Evaluate Options:

A: Policies—Core IAM component—correct.

B: Subnets—Networking, not IAM.

C: Instances—Compute, not IAM.

D: VCN—Networking, not IAM.

Reasoning: Only A is an IAM element—others are resources.

Conclusion: A is correct.

OCI documentation states: “IAM includes components like policies (A), groups, and compartments to control resource access.” B, C, and D are infrastructure, not IAM—only A fits per OCI’s IAM framework.

Detailed Answer in Step-by-Step Solution:

Objective: Visualize correlation between continuous and categorical features using ADS SDK.

Understand Correlation Types:

Continuous vs. Continuous: Pearson correlation.

Categorical vs. Categorical: Cramer’s V.

Continuous vs. Categorical: Correlation ratio (eta).

Evaluate Options:

A. corr(): General correlation (Pearson), not suited for mixed types—incorrect.

B. correlation_ratio_plot(): Plots correlation ratio for continuous-categorical—correct.

C. pearson_plot(): Not an ADS method; Pearson is continuous-only—incorrect.

D. cramersv_plot(): Cramer’s V for categorical-categorical—incorrect.

Reasoning: Correlation ratio measures association between continuous and categorical variables—ideal for heatmap in this mixed scenario.

Conclusion: B is correct.

OCI documentation states: “The correlation_ratio_plot() method (B) in ADS SDK generates a heatmap displaying the correlation ratio between continuous and categorical features, suitable for identifying highly correlated features for removal.” corr() (A) defaults to Pearson, pearson_plot() (C) isn’t real, and cramersv_plot() (D) is for categorical pairs—only B aligns with OCI’s ADS capabilities for this use case.
