Designing Network Infrastructure
Question
A large enterprise customer has a single router that uses two active/active 10-Mbps internet links in one of its offices. Each link currently handles approximately 7 Mbps of traffic, which is close to the full link capacity. When a link fails, the failure leads to significantly degraded performance of all applications. Static routing is used. The current ISP cannot deliver additional bandwidth capacity on the existing links. The customer needs a network design that is resistant to failure, but does not increase CAPEX. Which solution should be proposed to the customer?
Options
- AImplement quality of service on the current links.
- BAdd a third link to the current router.
- CAdd an additional edge router connected to a second ISP.
- DUse dynamic routing for equal-cost multipath.
