Redundancy Strategies

What is the primary goal of Continuity of Operations (COOP)?

• Maximizing productivity

• Ensuring critical functions continue during a disruption

• Enhancing network performance

• Reducing operational costs

Which of the following is an example of geographic redundancy?

• Using multiple hard drives in RAID

• Using cloud services across different regions

• Using load balancers within a single data center

• Implementing firewalls at multiple entry points

What type of site allows for immediate failover with minimal delay during disaster recovery?

• Cold site

• Warm site

• Hot site

• Co-located site

Which of the following configurations uses multiple passive nodes shared among multiple active nodes to reduce redundancy costs?

• Active/Active Clustering

• Active/Active Clustering

• N+M Configuration

• Active/Passive Clustering

Which backup solution allows for quick recovery from a system crash by creating a real-time duplicate of data?

• Incremental backup

• Differential backup

• Full backup

• Mirroring

What does a 99.999% system availability (five nines) allow in terms of downtime per year?

• 32 seconds

• 5 minutes

• 52 minutes

• 52 minutes

Which of the following testing methods is used to assess system performance under high loads?

• Failover testing

• Load testing

• Simulation

• Parallel processing

Which of the following strategies helps organizations ensure business continuity by using multiple vendors for critical systems?

• Platform diversity

• Vendor lock-in

• Vendor diversity

• Capacity planning

What does "scaling out" refer to in the context of redundancy and high availability?

• Increasing power of existing resources

• Adding more resources in parallel

• Reducing the load on existing resources

• Migrating to a different data center

Which of the following redundancy configurations ensures that both nodes are processing connections simultaneously?

• Active/Passive

• Active/Active
