QUESTION 62
A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub and spoke, and the branches use DMVPN back to the hub using two 100 Mbps internet connections. Both links must be used due to spikes in traffic, and routing must take traffic utilization of the links into account. Also, the branch routers have limited memory and CPU resources. Which routing protocol and design solution must the company choose?
A. iBGP with the hub routers set up as route reflectors and branches set up as clients
B. EIGRP with branch routers as stub routers using ECMP
C. OSPF deployed in area 0 with branch routers connecting from area 1
D. ISIS with the hub and spoke routers configured in two different areas
Correct Answer: B

QUESTION 65
A company wants to switch from static to dynamic routing. The branches use DMVPN back to the hub using two internet connections. One internet connection speed is 10 Mbps, and the other is 100 Mbps.

Which routing protocol and design solution must the company choose for optimal traffic forwarding during peak traffic times?
A. OSPF deployed in area 0 with branch routers connected back via virtual links
B. EIGRP with branch routers as stub routers and variance enabled
C. ISIS with the hub and spoke routers configured in two different areas
D. iBGP with the hub routers set up as route reflectors
Correct Answer: B

A. hybrid manual tunnel model
B. hybrid ISATAP tunnel model
C. dual-stack model
D. service block model
Correct Answer: C
