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
Hot site
Cold site
What is the key difference between business continuity and continuity of operations (COOP)?
COOP focuses on long-term recovery
Business continuity addresses only IT systems
COOP focuses on immediate response to disruptions
Business continuity excludes disaster recovery
Which of the following tests simulates real-world disaster recovery scenarios to assess system resilience?
Tabletop exercises
Failover testing
Simulation
Parallel processing
What is a benefit of active/passive clustering over active/active clustering?
Better performance during failover
Reduced hardware costs
Simultaneous connection processing
Higher performance during normal operations
Which backup testing method involves verifying that backups can be successfully restored without disrupting live systems?
Parallel processing
Failover testing
Load testing
Backup restoration simulation
Why is geographic dispersion important for disaster recovery?
It improves system performance
It reduces costs associated with infrastructure
It minimizes the impact of regional disasters
It simplifies data management
Which of the following is NOT a typical component of high-availability infrastructure?
Redundant power supplies
Geographically diverse data centers
Single points of failure
Backup generators
