Q8. Which two of these are correct regarding the recommended practice for distribution layer design? (Choose two.) 

A. use a redundant link to the core 

B. use a Layer 2 link between distribution switches 

C. never use a redundant link to the core because of convergence issues 

D. use a Layer 3 link between distribution switches with route summarization 

E. use a Layer 3 link between distribution switches without route summarization 

Answer: A,D 

Q9. A network administrator wants to provide high availability in a data center environment by making sure that there is no reconvergence of Layer 2 and Layer 3 protocols when there is a Layer 3 switch failure..Which Cisco Nexus feature fulfills this purpose?

Q10. Which of the following two statements about Cisco NSF and SSO are the most relevant to the network designer? (Choose two.) 

A. You can reduce outages to 1 to 3 seconds by using SSO in a Layer 2 environment or Cisco NSF with SSO in a Layer 3 environment. 

B. SSO and NSF each require the devices to either be graceful restart-capable or graceful restart-aware. 

C. In a fully redundant topology adding redundant supervisors with NSF and SSO may cause longer convergence times than single supervisors with tuned IGP timers
