Q106. Refer to the exhibit. 

Which two options are two characteristics of the single-tier headend architecture for DMVPN designs? (Choose two.) 

A. The mGRE and crypto functions are on the same router. 

B. Each DMVPN cloud has two different headend routers for high availability purposes.

Answer: AC 


Q107. A network designer has provisioned a router to use IPsec to encrypt the traffic over a GRE tunnel going to a web server at a remote location. From the router, the network designer can ping the web server, although the users in the office comment that they are unable to reach it. (Note: The DF bit is not set.) Which aspect should be changed in the design of the virtual connection? 

A. IP addresses of the GRE tunnel endpoints 

B. IPsec configuration 

C. MTU size on the GRE tunnel 

D. encapsulation of the GRE tunnel 

Answer:

C. Each component can be funded by different organizations based on its role. 

D. Each component can support multiple roles based on the requirements. 

E. Each component can provide redundancy for applications and services. 

Answer: AB 


Q109. You are designing a network to support data, voice and video. Which two main factors will you address to improve network convergence? (Choose two.) 

A. event propagation delay 

B. failure detection delay 

C. forwarding engine update delay 

D. routing table recalculation delay 

Answer: BD 


Q110. You have been hired to redesign a network due to issues with congestion. How will a router function if the QoS mechanism of congestion avoidance is integrated into the existing network design? 

A. the router handles the overflow of traffic by using FIFO B. the router handles the possible buildup of congestion by using WRED 

C. the router forces inbound and outbound traffic to stay within a defined profile by using rate limiting 

D. the router separates packets based on certain characteristics by using NBAR 

E. the router marks packets based on certain characteristics by using PBR
