Question # 105

Which two aspects are considered when designing a dual hub dual DMVPN cloud topology? (Choose two )

will only work with single-tier headend architecture

hub sites must connect to both DMVPN clouds

recommended for high availability

spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly

requires all sites to have dual Internet connections

Question # 106

Network designers often segment networks by creating modules for various reasons Sometimes however a network can be unintentionally segmented For instance, if the only way to connect a remote site to a headquarters or regional site is to connect them both to the public Internet the corporate network is now unintentionally segmented Which of the following option can be used to desegment the network in this situation?

Build virtual networks that pass over the network

Mark traffic for special handling through quality of service

Configure little to no control data plane policy

Block specific sources from reaching specific destinations

Question # 108

Company XYZ has two offices connected to each other over unequal redundant paths and they are running OSPF as the routing protocol An external network architect recommends BFD for OSPF Which effect would BFD have in the case of a link failure?

It would drop the dead per detection time to a single hello

It would keep an alternate path ready in case of a link failure

It would optimize the route summarization feature of OSPF

It would detect that the neighbor is down in a subsecond manner

Question # 109

What statement describes the application layer as defined in the software-defined networking architecture?

This layer is responsible for collecting the network status such as network usage and topology.

This layer contains programs that communicate their desired network behavior to controllers.

This layer is responsible for handling packets based on the rules provided by the controller.

This layer processes the instructions and requirements sent by networking components.
