QUESTION: 31

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

Minimize app downtime
Reduce the frequency of failures requiring human intervention
Increase time spent on developing new features
Dependencies on hardware or software that is difficult to scale

Answer(s): A

Explanation:

-Resilience is the ability of a system to withstand and recover from disruptions.
-Security is the ability of a system to protect itself from unauthorized access, use, disclosure, disruption, modification, or destruction.
-Modular design is a design that breaks down a system into smaller, independent modules.
-Downtime is the period of time when a system is not available.

A resilient and secure modular network design will minimize app downtime by:

-Providing multiple paths for traffic to flow, so that if one path fails, traffic can still flow through the other paths.
-Using redundant components, so that if one component fails, another component can take over its function.
-Implementing fault-tolerant mechanisms, such as load balancing and heartbeats, to detect and recover from failures.

By minimizing app downtime, a resilient and secure modular network design can help to ensure that applications are always available to users. This is important for businesses that rely on their applications to operate.

The other options are not as important as minimizing app downtime.

-Reducing the frequency of failures requiring human intervention is important, but it is not as important as minimizing app downtime.
-Increasing time spent on developing new features is important, but it is not as important as minimizing app downtime.
-Dependencies on hardware or software that is difficult to scale can be a problem, but it is not as important as minimizing app downtime.

QUESTION: 32

Refer to the exhibit.

For Company XYZ, Bangkok is using ECMP to reach the 172.20.2.0/24 network. The company wants a design that would allow them to forward traffic from 172.16.2.0/24 toward 172.20.2.0/24 via the Singapore router as the preferred route. The rest of the traffic should continue to use ECMP. Which technology fulfills this design requirement?

policy-based routing
unequal-cost load balancing using variance
route summarization
LFA

QUESTION: 33

Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment. The solution must scale when new networks are added into the network in the near future. Which technology can be used to meet these requirements?

single point route-redistribution with route filtering using route tags
multipoint route-redistribution with route filtering using ACLs
multipoint route-redistribution with route filtering using route tags
single point route-redistribution with route filtering using ACLs

QUESTION: 34

What are two common approaches to analyzing and designing networks? (Choose two.)

three-tier approach
top-down approach
high-low security approach
bottom-up approach
left-right approach

Answer(s): B,D

Explanation:

B) Top-down approach: This approach involves starting with the high-level requirements and goals of the network design and then gradually breaking them down into more detailed components. It focuses on understanding the overall business needs and objectives before diving into the technical details. This approach helps ensure that the network design aligns with the organization's goals and provides a holistic view of the network requirements.

D) Bottom-up approach: This approach involves starting with the individual components and gradually building up the network design from the ground up. It focuses on the specific technical details, such as network protocols, hardware, and configurations, and then combines them to form a complete network design. This approach is more focused on the technical aspects and can be useful for understanding the specific implementation details of the network.

QUESTION: 35

Refer to the exhibit.

OSPF is running as the IGP to provide reachability to all AS100 networks. R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Area1. Now BGP must be deployed within AS100 because it will be receiving Internet routes from its eBGP peers (the service provider) connected to R1 andR2. What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must be redistributed at R1 and R2 into OSPF.
Confederation should be set up with R1, R5, and R3 in one sub AS, with R2 and R4 in another, and redistribution at R1 and R2.
R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only. R5 must not be a route reflector.
A full mesh should be deployed between all the routers with mutual redistribution to take place at R1 and R2.
