Security experts promote the security defense-m-depth principle which states that network security should be multilayered and modular and multiple methods should be designed and applied to different parts of the network Drag and drop the characteristics on the left to the matching enterprise network components on the right.
A company plans to use BFD between its routers to detect a connectivity problem inside the switched network. An IPS is transparently installed between the switches. Which packets should the IPS forward for BFD to work under all circumstances?
While positive feedback loops generally don ' t last long enough to bring down a network completely, they can still last long enough to disrupt traffic flows or to cause the network to converge more slowly than it should.
What are two examples of cases where a positive feedback loop can be long-lived and devastating to the network ' s control plane? (Choose two)

An organization has two branches connected over the Internet circuit using IPsec tunnels established on their edge routers belonging to different vendors Recently these branches were the victims of a DoS attack resulting in failure to establish the tunnels They are now looking for a better tunneling solution allowing full interoperability between vendors and allowing a standardized set of authentication methods Furthermore the solution must support detection of the peer’s state as well as having support for next-gen encryption algorithms. Which protocol meets these requirements and is known to be resistant to DoS attacks?
How many fully established neighbour relationships exist on an Ethernet with five routers running OSPF as network type broadcast?
Company XYZ wants to use the FCAPS ISO standard for network management design, focusing on minimizing outages through detection, isolation, and corrective actions. Which layer accomplishes this design requirement?
A key to maintaining a highly available network is building in the appropriate redundancy to protect against failure. This redundancy is carefully balanced with the inherent complexity of redundant systems. Which design consideration is relevant for enterprise WAN use cases when it comes to resiliency?
SDN is still maturing Throughout the evolution of SDN which two things will play a key role in enabling a successful deployment and avoiding performance visibility gaps in the infrastructure’ (Choose two.)
