200-301 Question 144
Select 2A network administrator is tasked with deploying a solution to isolate multiple routing tables on a single physical router. At the same time, the organization’s developers are requesting lightweight, portable environments to run their applications. Which combination of technologies would be the most appropriate to meet these requirements?
- A
Virtual Routing and Forwarding (VRF) for routing table isolation
- B
Server virtualization for creating lightweight application environments
- C
Containers for lightweight, portable application environments
- D
Dedicated physical servers for each routing table
- E
VRF and containers together for routing and lightweight application environments
Show answer and explanation
Correct answers: A, C
Explanation
To meet the requirements, VRF is used to isolate multiple routing tables on a single physical router, while containers provide lightweight and portable environments for running applications. These technologies address the specific needs of the network administrator and the developers without unnecessary complexity or hardware investment.
- A. Correct.
VRF (Virtual Routing and Forwarding) allows multiple routing tables to coexist on the same physical device, making it the correct choice for routing table isolation.
- B. Incorrect.
Server virtualization focuses on creating virtual machines for running operating systems, which is not lightweight or ideal for portable application environments. Therefore, it is not suitable for this scenario.
- C. Correct.
Containers are lightweight, portable environments ideal for running applications, making them the correct choice for the developers' needs.
- D. Incorrect.
Using dedicated physical servers for each routing table is inefficient and does not align with modern networking or virtualization practices.
- E. Incorrect.
While VRF and containers are valuable separately, they do not directly integrate as one single solution. The question requires identifying the individual technologies that meet the two specific requirements.
