Question 308

Report Export Collapse

A software-defined network can be defined as a network with an API that allows applications to understand and react to the state of the network in near real time. A vendor is building an SDN solution that exposes an API to the RIB and potentially the forwarding engine directly. The solution provides off-box processes with the capability to interact with the routing table in the same way as a distributed routing process. Which SDN framework model does the solution use?

Question 309

Report Export Collapse

A large enterprise customer is planning a new WAN connection to its headquarters. The current architecture is dual homed with static routing, but users complain when a specific link fails. Failure of the other link does not affect any services or applications. The new WAN connection must provide the headquarters with a resilient network design and increase the return on investment.

Which solution should be recommended to the customer?

Question 310

Report Export Collapse

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?

You were tasked to enhance the security of a network with these characteristics: • A pool of servers is accessed by numerous data centers and remote sites • The servers are accessed via a cluster of firewalls • The firewalls are configured properly and are not dropping traffic • The firewalls occasionally cause asymmetric routing of traffic within the server data center. Which technology should you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstation and redirecting flows at the servers?
