QUESTION 93
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?

Refer to the diagram.

Which solution must be used to send traffic from the foreign wireless LAN controller to the anchor wireless LAN controller?

QUESTION 97
As a network designer you need to support an enterprise with hundreds of remote sites connected over a single WAN network that carries different types of traffic, including VoIP, video, and data applications which of following design considerations will not impact design decision?

QUESTION 98
What is the most important operational driver in building a resilient and secure modular network design?

QUESTION 99
Refer to the exhibit.

A customer runs OSPF with Area 5 between its aggregation router and an internal router When a network change occurs in the backbone. Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5 You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B does not support the stub area How can you accomplish this task*?

QUESTION 100
Retef to the exhibit.

An engineer is designing a multiarea OSPF network for a client who also has a large EIGRP domain EIGRP routes are getting redistributed into OSPF ,OSPF area 20 has routers with limited memory and CPU resources The engineer wants to block routes from EIGRP 111 from propagating into area 20 and allow EIGRP 222 routes to How in Which OSPF area type fulfills this design requirement?

QUESTION 101

QUESTION 103
How many fully established neighbour relationships exist on an Ethernet with five routers running OSPF as network type broadcast?

QUESTION 104
Company XYZ must design a strategy to protect their routers from DoS attacks, such as traffic destined to the router’s own route processor, using separate control plane categories. Which two capabilities can be used to achieve this requirement? (Choose two.)

QUESTION 105
You have been asked to design a high-density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

QUESTION 106
Two routers R1 and R2 are directly connected through an Ethernet link. Both routers are running OSPF over the Ethernet link and OSPF has been registered with BFD. R1 has been set up to transmit BFD at a 50 ms interval, but R2 can receive only at a 100 ms rate due to platform limitations. What does this mean?

QUESTION 107
Customer XYZ network consists of an MPLS core. IS-IS running as IGP a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements.
