200-301 Question 143
Select 2A network administrator is tasked with deploying multiple isolated routing tables on a single physical router to support different customers' networks. At the same time, the administrator is also exploring lightweight methods to deploy applications in isolated environments on a shared operating system to optimize server resource usage. Which technologies should the administrator use for these tasks?
- A
Virtual Routing and Forwarding (VRF) for isolated routing tables
- B
Server virtualization for isolated routing tables
- C
Containers for lightweight application isolation
- D
Physical servers for lightweight application isolation
- E
Hypervisors for both isolated routing tables and lightweight application isolation
Show answer and explanation
Correct answers: A, C
Explanation
The administrator needs to address two specific tasks: isolated routing tables and lightweight application isolation. VRFs are the correct choice for isolating routing tables on a single router, while containers offer a resource-efficient solution for lightweight application isolation. Other technologies like server virtualization, physical servers, and hypervisors are not suited to this particular combination of requirements.
- A. Correct.
VRFs allow multiple isolated routing tables to exist on a single physical router, making it the correct technology for managing isolated routing tables in this scenario.
- B. Incorrect.
Server virtualization is primarily used to create virtual machines with separate operating systems, which is not directly related to isolated routing tables.
- C. Correct.
Containers provide lightweight application isolation by sharing the host operating system while maintaining application separation. This is the correct solution for lightweight application deployment.
- D. Incorrect.
Physical servers are not an efficient or practical solution for lightweight application isolation, as they lack the flexibility and resource optimization provided by containers.
- E. Incorrect.
Hypervisors are used to manage virtual machines, but they are not directly applicable to VRFs or lightweight application isolation using containers in this scenario.
