Q11. Two companies recently merged and want to integrate their networks. Both utilize EIGRP to support their complex enterprise networks. Which action can improve the performance of these two separate EIGRP domains? 

A. Enable route summarization at redistribution points. 

B. Adjust the administrative distance to prefer the best routes to each destination. 

C. Remove EIGRP and utilize OSPF instead. 

D. Utilize EIGRP stub routing between the network boundaries of the companies. 

Answer: A 


Q12. Which option describes the effect of using softphones instead of VoIP handsets on QoS implementation for the voice traffic? 

A. It provides a Layer 2 CoS marking in the frames that can be used for QoS implementation. 

B. Using softphones means that 802.1Q tagging must be configured between the PC and the switch. 

C. The voice traffic of softphones is mixed with data traffic of PC on the access VLAN. 

D. By using softphones, the implementation of a QoS depends only on trusting DSCP markings set by the PC. 

Answer: C 


Q13. Which of these statements is correct regarding Stateful Switchover and Cisco Nonstop Forwarding? 

A. Utilizing Cisco NSF in Layer 2 environments can reduce outages to one to three seconds. 

B. Utilizing SSO in Layer 3 environments can reduce outages to one to three seconds. 

C. Distribution switches are single points of failure causing outages for the end devices. 

D. Utilizing Cisco NSF and SSO in a Layer 2 environment can reduce outages to less than one second. 

E. NSF and SSO with redundant supervisors have the most impact on outages at the access layer. 

Answer: E 


Q14. 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 

D. The primary deployment scenario for Cisco NSF with SSO is in the Distribution and Core layers. 

E. Cisco NSF-aware neighbor relationships are independent of any tuned IGP timers 

Answer: A,C
