CV0-004 Operations and Support Practice Test 1 — 15 Questions

Question 1

A company is planning a disaster recovery testing strategy. They want to validate both RTO and RPO without impacting production. Which THREE approaches should they consider? (Choose THREE.)

Accepted Answer

Perform regular backup restoration tests. Regular backup restoration tests (A) verify data integrity and RPO. Scheduled DR drills in a separate environment (B) validate RTO without impact. Continuous monitoring (E) provides ongoing validation of RTO/RPO metrics without production impact. Chaos engineering in production (D) would impact operations, and load testing (C) is performance-focused, not recovery. Therefore, A, B, and E are the appropriate approaches.

Answer

Run load tests against production systems

Answer

Use chaos engineering to inject failures in production

Question 2

A cloud administrator notices that an application's latency has increased. The application is distributed across multiple microservices. Which tool can help trace requests across services to identify the bottleneck?

Accepted Answer

Distributed tracing tool. Distributed tracing tools provide end-to-end tracing of requests as they travel through your application, helping to pinpoint performance issues and bottlenecks across microservices.

Answer

Centralized logging service

Answer

Vulnerability assessment tool

Answer

Audit logging service

Question 3

A cloud administrator is tasked with monitoring CPU utilization across a fleet of virtual machines. Which cloud service should be used to collect and visualize this metric?

Accepted Answer

Cloud monitoring service. The cloud monitoring service is the native tool that collects and visualizes metrics such as CPU utilization.

Answer

Audit logging service

Answer

Configuration management service

Answer

Advisor or optimization service

Question 4

A cloud architect is designing a monitoring solution for a web application. Which service should they use to collect and visualize metrics such as CPU utilization and network throughput?

Accepted Answer

AWS CloudWatch. AWS CloudWatch is the service for collecting and visualizing metrics on AWS.

Answer

AWS CloudTrail

Answer

AWS Config

Answer

AWS Trusted Advisor

Question 5

A company wants to receive alerts when their cloud costs exceed a budget threshold. Which cost management feature should they use?

Accepted Answer

Cost anomaly detection alerts. Cost anomaly detection alerts are designed to identify unusual spending patterns using machine learning, not for alerting against a predefined budget threshold. The correct cloud cost management feature for receiving alerts when costs exceed a budget threshold is budget alerts (e.g., AWS Budgets, Azure Budgets), which is not among the listed options. Therefore, none of the provided options is correct.

Answer

Rightsizing recommendations

Answer

Reserved Instance planning

Answer

Tagging strategy

Question 6

A cloud administrator is configuring automated scaling for a web application. The scaling policy should add two instances when CPU utilization exceeds 80% for five minutes. Which type of scaling policy should they implement?

Accepted Answer

Step scaling. Step scaling allows adding a specific number of instances based on a metric threshold breach.

Answer

Scheduled scaling

Answer

Dynamic scaling

Answer

Target tracking scaling

Question 7

A systems administrator notices that an application is slow to respond. They want to analyze the latency of individual requests across microservices. Which tool should they use?

Accepted Answer

AWS X-Ray. Distributed tracing tools like AWS X-Ray help identify latency across services.

Answer

CloudWatch Logs

Answer

VPC Flow Logs

Answer

AWS CloudTrail

Question 8

A company uses multiple AWS accounts. The cloud team wants to allocate costs to specific business units. What should they implement?

Accepted Answer

Tagging strategy. A tagging strategy with tags like environment, team, and project enables cost allocation.

Answer

Cost Explorer

Answer

AWS Budgets

Answer

AWS Organizations

Question 9

A cloud engineer is setting up automated patching for Linux instances in AWS. They need to define a maintenance window during which patches are applied. Which service should they use?

Accepted Answer

AWS Systems Manager Patch Manager. AWS Systems Manager Patch Manager provides automated patching with maintenance windows.

Answer

AWS Config

Answer

AWS OpsWorks

Answer

Amazon Inspector

Question 10

A company's disaster recovery plan requires them to restore a database to a specific point in time. Which backup strategy should they use?

Accepted Answer

Continuous replication for DR. Continuous replication enables point-in-time recovery by maintaining ongoing changes.

Answer

Cross-region replication

Answer

Full daily backup

Answer

Snapshot-based backup

Question 11

A cloud administrator is troubleshooting a network connectivity issue between two subnets. They suspect a security group or NACL is blocking traffic. Which tool should they use to analyze the traffic flow?

Accepted Answer

VPC Flow Logs. VPC Flow Logs capture network traffic metadata, helping identify dropped packets.

Answer

AWS X-Ray

Answer

AWS CloudTrail

Answer

AWS Config

Question 12

A cloud engineer needs to ensure that an auto-scaling group does not launch new instances immediately after a scale-in event to allow metrics to stabilize. Which feature should they configure?

Accepted Answer

Cooldown periods. Cooldown periods prevent premature scaling by allowing metrics to stabilize.

Answer

Health checks

Answer

Scheduled scaling

Answer

Lifecycle hooks

Question 13

A cloud administrator wants to be notified immediately via email when a critical alert is triggered. Which notification channel should they configure?

Accepted Answer

Email. Email is a typical notification channel for alerts.

Answer

AWS Config
