CompTIA Network+ Certification Exam Sample Questions (Q106-Q111):

NEW QUESTION # 106
Which of the following steps in the troubleshooting methodology would be next after putting preventive measures in place?

  • A. Verify system functionality.
  • B. Implement the solution.
  • C. Test the theory to determine cause.
  • D. Establish a plan of action.

Answer: A

Explanation:
Explanation: After implementing a solution and putting preventive measures in place, the next step is to verify that the system is functioning correctly. This ensures that the issue has been fully resolved.


NEW QUESTION # 107
Two companies successfully merged. Following the merger, a network administrator identified a connection bottleneck. The newly formed company plans to acquire a high-end 40GB switch and redesign the network from a three-tier model to a collapsed core. Which of the following should the administrator do until the new devices are acquired?

  • A. Implement the FHRP.
  • B. Enable link aggregation.
  • C. Configure a route selection metric change.
  • D. Install a load balancer.

Answer: B

Explanation:
*The issue described is a network bottleneck due to increased traffic after a merger.
*A collapsed core architecture consolidates the core and distribution layers into a single layer to improve efficiency and reduce latency.
*Until the 40GB switch is acquired, Link Aggregation (LAG) (IEEE 802.3ad / LACP) can be used to combine multiple physical links into a single logical link, increasing bandwidth and reducing bottlenecks.
*FHRP (First Hop Redundancy Protocol) (A) is used for gateway redundancy, not link aggregation.
*Route selection metric changes (B) help with routing decisions but don't address physical link congestion.
*Load balancers (C) distribute traffic for applications, not network links.

NEW QUESTION # 108
Which of the following disaster recovery concepts is calculated by dividing the total hours of operation by the total number of units?

  • A. RTO
  • B. MTTR
  • C. MTBF
  • D. RPO

Answer: C

Explanation:
* Introduction to Disaster Recovery Concepts:
* Disaster recovery involves strategies and measures to ensure business continuity and data recovery in the event of a disaster.
* Mean Time Between Failures (MTBF):
* MTBF is a reliability metric used to predict the time between failures of a system during operation. It is calculated by dividing the total operational time by the number of failures.
* Formula: MTBF=Total Operational TimeNumber of Failurestext{MTBF} = frac{text{Total Operational Time}}{text{Number of Failures}} MTBF=Number of FailuresTotal Operational Time
* This metric helps in understanding the reliability and expected lifespan of systems and components.
* Example Calculation:
* If a server operates for 1000 hours and experiences 2 failures, the MTBF is:
MTBF=1000 hours2=500 hourstext{MTBF} = frac{1000 text{ hours}}{2} = 500 text{ hours} MTBF=21000 hours=500 hours
* Explanation of the Options:
* A. MTTR (Mean Time to Repair): The average time required to repair a system after a failure.
* B. MTBF (Mean Time Between Failures): The correct answer, representing the average time between failures.
* C. RPO (Recovery Point Objective): The maximum acceptable amount of data loss measured in time.
* D. RTO (Recovery Time Objective): The target time set for the recovery of IT and business activities after a disaster.
* Conclusion:
* MTBF is a crucial metric in disaster recovery and system reliability, helping organizations plan maintenance and predict system performance.


NEW QUESTION # 109
A newtwork administrator needs to create an SVI on a Layer 3-capable device to separate voice and data traffic. Which of the following best explains this use case?

  • A. A logical interface used for the routing of VLANs
  • B. A logical interface used when the number of physical ports is insufficent.
  • C. A physical interface used for management access
  • D. A physical interface used for trunking logical ports

Answer: A

Explanation:
An SVI (Switched Virtual Interface) is a logical interface on a Layer 3-capable switch used to route traffic between VLANs. This is particularly useful in environments where voice and data traffic need to be separated, as each type of traffic can be assigned to different VLANs and routed accordingly.
* SVI (Switched Virtual Interface): A virtual interface created on a switch for inter-VLAN routing.
* VLAN Routing: Enables the routing of traffic between VLANs on a Layer 3 switch, allowing for logical separation of different types of traffic, such as voice and data.
* Use Case: Commonly used in scenarios where efficient and segmented traffic management is required, such as in VoIP implementations.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Discusses VLANs, SVIs, and their applications in network segmentation and routing.
* Cisco Networking Academy: Provides training on VLAN configuration and inter-VLAN routing using SVIs.
* Network+ Certification All-in-One Exam Guide: Covers network segmentation techniques, including the use of SVIs for VLAN routing.


NEW QUESTION # 110
Which of the following should a network administrator configure when adding OT devices to an organization's architecture?

  • A. Time-based authentication
  • B. Data-at-rest encryption
  • C. Network segmentation
  • D. Honeynet

Answer: C

Explanation:
Network segmentation involves dividing a network into smaller segments or subnets. This is particularly important when integrating OT (Operational Technology) devices to ensure that these devices are isolated from other parts of the network. Segmentation helps protect the OT devices from potential threats and minimizes the impact of any security incidents. It also helps manage traffic and improves overall network performance.
