200-301 Question 56
Single answerA branch office of your organization needs to connect to the headquarters over a Wide Area Network (WAN) for secure data transmission and cost efficiency. The branch office has a limited budget but requires reliable connectivity for accessing critical applications hosted at the headquarters. Which WAN technology would be the most suitable for this scenario?
- A
MPLS (Multiprotocol Label Switching)
- B
Internet VPN with IPSec
- C
Leased Line
- D
Satellite Internet
Show answer and explanation
Correct answer: B
Explanation
Internet VPN with IPSec is the most suitable WAN technology for this scenario because it provides a cost-efficient and secure way to connect a branch office to the headquarters over the public Internet. It ensures data confidentiality and integrity while maintaining a balance between cost and reliability, addressing both the technical and budgetary requirements of the branch office.
- A. Incorrect.
MPLS offers high reliability and performance for enterprise-grade WANs, but it can be expensive, making it less suitable for a branch office with a limited budget.
- B. Correct.
Internet VPN with IPSec provides secure data transmission over the public Internet at a lower cost, making it an ideal choice for branch offices with limited budgets that need secure and reliable connectivity.
- C. Incorrect.
Leased lines offer high reliability and dedicated bandwidth, but they are significantly more expensive compared to other WAN options, making them less practical for budget-restricted scenarios.
- D. Incorrect.
Satellite Internet could be an option for remote locations, but it often suffers from high latency and relatively higher costs compared to Internet VPNs, making it less suitable for this use case.
