質問 # 343
Which of the following disaster recovery concepts is calculated by dividing the total hours of operation by the total number of units?

正解：B

解説：
* 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 Failures\text{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 hours\text{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.

Which of the following diagrams would most likely include specifications about fiber connector types?

正解：D


質問 # 345
Users are experiencing significant lag while connecting to a cloud-based application during peak hours. An examination of the network reveals that the bandwidth is being heavily utilized. Further analysis shows that only a few users are using the application at any given time. Which of the following is the most cost-effective solution for this issue?

正解：B

解説：
QoS (Quality of Service) allows the network administrator to prioritize critical traffic - such as the cloud-based application - over less important traffic. This ensures that even during high bandwidth usage, essential application traffic maintains acceptable performance.
Limiting users is restrictive and does not address the root cause. Leasing a Direct Connect (or dedicated line) is effective but expensive, not cost-effective for most use cases. A CDN (Content Delivery Network) improves performance for static content delivery, not for cloud applications requiring real-time interaction.
Implementing QoS is the most cost-effective way to reduce lag for prioritized application traffic during congestion.


質問 # 346
Which of the following must be implemented to securely connect a company's headquarters with a branch location?

正解：D

解説：
Site-to-Site VPN: A site-to-site VPN is used to securely connect two networks, such as a company's headquarters and a branch location, over the internet. This type of VPN creates a secure tunnel for data transmission, ensuring confidentiality and integrity.
Split-tunnel VPN (A): Allows some traffic to bypass the VPN tunnel, which may not secure all communications.
Clientless VPN (B): Used for individual users to access the network without VPN client software.
Full-tunnel VPN (C): Typically used for individual user traffic rather than connecting two networks.


質問 # 347
A company is building a new campus that will have wired and wireless devices. The network will be designed to support casual internet usage for guests and break rooms for employees. Which of the following authentication methods is best suited for guests given the requirements of this scenario?

正解：A
