CompTIA Network+ Practice Test for Subdomain 3.3 #01

Question 1

The IT director at a regional hospital is working with the risk management team to define disaster recovery requirements for the patient records database. After reviewing operational tolerances, the team agrees that no more than four hours of patient transaction data should ever be lost in the event of a system failure or disaster. Which DR metric defines the maximum acceptable amount of data loss, measured in time, that an organization can tolerate following a failure?

A. Recovery Time Objective (RTO) B. Mean Time to Repair (MTTR) C. Recovery Point Objective (RPO) D. Mean Time Between Failures (MTBF)

Question 2

A systems engineer at an e-commerce company is documenting business continuity requirements for the company's online storefront. The executive team has determined that if the storefront experiences a complete outage, it must be fully restored and operational within two hours in order to prevent unacceptable revenue loss and reputational damage. Which disaster recovery metric defines the maximum allowable time that a system or service can remain offline following a failure before the business impact becomes unacceptable?

A. Recovery Point Objective (RPO) B. Mean Time Between Failures (MTBF) C. Recovery Time Objective (RTO) D. Mean Time to Repair (MTTR)

Question 3

A help desk manager reviewing quarterly incident reports at a university data center notices that the campus core switch failed three times over the past three months. The first failure required six hours to resolve, the second took two hours, and the third took four hours. Her director asks her to compute a key reliability metric that reflects average repair time, which will inform a hardware refresh proposal. Which DR metric is being calculated, and what is the correct result?

A. Recovery Point Objective (RPO); 4 hours B. Mean Time Between Failures (MTBF); 4 hours C. Recovery Time Objective (RTO); 6 hours D. Mean Time to Repair (MTTR); 4 hours

Question 4

A junior network engineer at a manufacturing plant is reviewing the technical datasheet for a critical industrial switch used on the production floor. The operations team wants to understand how often the switch is statistically expected to fail during normal operating conditions, in order to plan preventive maintenance schedules and determine appropriate spare parts inventory levels. The manufacturer's datasheet provides this figure as part of the device's reliability specification. Which disaster recovery metric measures the average operational time a device is expected to run between successive failures?

A. Recovery Time Objective (RTO) B. Mean Time to Repair (MTTR) C. Recovery Point Objective (RPO) D. Mean Time Between Failures (MTBF)

Question 5

Your organization's business continuity team is evaluating DR site options for a back-office payroll application that processes data only at the end of each month. The team has determined that cost is the primary factor, and leadership accepts that restoration could take several days following a disaster declaration. The selected facility will provide only physical space, power, and basic environmental controls, with no pre-installed servers, network equipment, or configured software. Which type of DR site is being described?

A. Hot site B. Warm site C. Cold site D. Active-passive cluster

Question 6

A network consultant is advising a regional law firm on disaster recovery planning for its document management system. The firm requires a DR site that is more cost-effective than a fully operational standby environment, yet can be brought online significantly faster than a site with no pre-staged equipment. The selected site will include pre-installed servers and networking gear, but systems will require configuration updates and data restoration from the latest backup tape before staff can resume work after a disaster. Which type of DR site best matches this description?

A. Hot site B. Cold site C. Warm site D. Tabletop site

Question 7

The network team at a financial trading company is defining disaster recovery requirements for the firm's primary trading platform. Regulatory obligations and business operations require that if the primary data center goes offline, the trading platform must resume within minutes with no manual infrastructure provisioning and with data loss measured in seconds, not hours. Continuous synchronous data replication between sites is already in place to support this requirement. Which type of DR site is specifically designed to support this level of near-instantaneous failover?

A. Cold site B. Warm site C. Hot site D. Tabletop site

Question 8

A technician is reviewing the high-availability architecture documentation for a pair of web application load balancers deployed at an enterprise data center. According to the documentation, both load balancer units are simultaneously processing live production traffic and distributing session requests across backend servers, and either unit is capable of handling the entire session load independently if the other fails. This design was selected specifically to maximize both redundancy and throughput capacity. Which high-availability approach does this configuration represent?

A. Active-passive B. Cold standby C. Active-active D. Warm failover

Question 9

A network administrator at a regional bank has deployed two firewall appliances to eliminate a single point of failure at the network perimeter. In the current deployment, only the primary firewall is actively inspecting and forwarding production traffic. The secondary firewall maintains synchronization with the primary through a heartbeat link and holds a copy of the session table, but it does not process any user traffic until the primary unit fails. Upon detecting a failure, the secondary firewall automatically assumes the primary's IP address and resumes all active sessions. Which high-availability approach does this configuration represent?

A. Active-active B. Hot-site clustering C. Active-passive D. MTBF-based redundancy

Question 10

The IT manager at a logistics company schedules an annual disaster recovery review for operations and IT staff. During the session, department heads and key engineers gather in a conference room to walk step by step through a simulated ransomware attack scenario, discussing each team member's role, decision points, escalation paths, and the sequence of DR procedures that would be followed in a real event. No systems are touched, no failover is initiated, and production operations are not affected in any way. Which type of DR test is being conducted?

A. Validation test B. Full interruption test C. Tabletop exercise D. Parallel test
