FREE CompTIA Cloud+ High Availability and Recovery Questions and Answers

Question 1

A financial application requires that database transactions are written to both a primary and a secondary database in different availability zones simultaneously.
A transaction is only considered complete after it is successfully committed to both locations to ensure zero data loss in case of a failure.
Which type of replication does this scenario describe?

Accepted Answer

Synchronous replication

Answer

Asynchronous replication

Answer

Snapshot replication

Answer

Log shipping

Question 2

In a high-availability cluster configuration, two servers are set up to provide redundancy for a critical application. One server actively handles all requests, while the other remains in standby mode, ready to take over only if the primary server fails. What is this configuration called?

Accepted Answer

Active-passive cluster

Answer

Active-active cluster

Answer

Horizontal scaling

Answer

Round-robin load balancing

Question 3

Which of the following cloud architecture principles is MOST directly aimed at achieving fault tolerance by eliminating single points of failure?

Accepted Answer

Deploying redundant components across multiple availability zones

Answer

Implementing vertical scaling on a single large instance

Answer

Caching static content at a single edge location

Answer

Consolidating all application data onto a single, large storage volume

Question 4

A cloud administrator is configuring high availability for a web application where users log in and perform a series of actions. The application requires that once a user starts a session, all subsequent requests from that user are sent to the same backend server. Which load balancer configuration must be enabled to meet this requirement?

Accepted Answer

Session persistence

Answer

Round-robin routing

Answer

Health check monitoring

Answer

Geo-proximity routing

Question 5

An organization wants a cost-effective disaster recovery strategy in the cloud. The plan involves continuously replicating data to a secondary region and maintaining a minimal version of the core infrastructure, such as a small database instance and a single web server. In a disaster, this minimal environment will be scaled up to full production capacity to take over the workload. What is this DR strategy called?

Accepted Answer

Pilot Light

Answer

Multi-Site Active-Active

Answer

Backup and Restore

Answer

Warm Standby

Question 6

A company has determined that for a specific application, the maximum tolerable data loss is 15 minutes and the maximum tolerable downtime is 4 hours. Which disaster recovery solution BEST aligns with these RPO and RTO requirements in a cost-effective manner?

Accepted Answer

Asynchronous replication to a warm standby site

Answer

Daily backups to a cold site

Answer

Synchronous replication to a hot site

Answer

A geographically redundant active-active configuration
