A company plans to include Nonstop Forwarding and Bidirectional Forwarding Detection as a part of
their network redundancy plan.
In which two ways do NSF and BFD work together when different hardware platforms are compared?
(Choose two.)


A network design shows two routers directly connected to an Ethernet switch using optical connections.
There is an OSPF adjacency between the routers.
In this design, which solution will ensure that interface down detection is reported as quickly as possible to
the IGP?


A network designer is working with a company to improve convergence at the Layer 2 control plane and
decides to use LACP.
Which of these components does LACP use to create the system ID?


A network designer is redesigning an enterprise campus network to ensure that Ethernet switches proactively attempt to reconnect after a fiber cut. In the design, they will have to address areas where fiber cuts exist on campus from past troubleshooting, where a single fiber is disconnected in the fiber pair, leading to looping.
Which feature could be implemented in the design to allow the Spanning Tree Protocol on the switches to be protected?


A switched network is being designed to support a manufacturing factory. Due to cost constraints, fiber-based connectivity is not an option.
Which design allows for a stable network when there is a risk of interference from the manufacturing hardware in use on the factory floor?


A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A customer wants to connect one site with one box redundant to the Resilient Ethernet Protocol ring at two different service provider locations.
How can this be done without producing any Layer 2 loops within the network design?


You have created a network design that has two point-to-point Metro Ethernet circuits extending a single production VLAN between two data centers. Under normal circumstances, one circuit will carry traffic and spanning tree will block the other.
If the company wants you to make use of both circuits to carry production traffic, which two technologies and features will you investigate to integrate into your network design? (Choose two.)


Voice traffic between two campus enterprise networks is growing. The network designers decide to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in order to provide more bandwidth and diversity. The QoS profile will be the same on the new 10-Mb service due to the voice stability on the first Metro Ethernet link.
When the second link is added to the OSPF domain, which traffic design consideration would have the most impact on the voice traffic when both links are active?


You work as a network designer for a company that is replacing their Frame Relay WAN with an MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in their distribution routers, and they would like to advertise their access routers through the MPLS network. Their service provider, however, only supports 1000 prefixes per VRF.
Which two design solutions can be applied to ensure that your access routers will be able to reach all devices in your network? (Choose two.)


You are designing a network that will run EIGRP over a Metro Ethernet service that does not employ a link-loss technology.
What will be the impact on convergence if there is a break in the end-to-end Layer 2 connectivity within the service provider network?


A new video multicast application is deployed in the network. The application team wants to use the multicast group to stream the video to users. They want to know if this choice will impact the existing multicast design.
What impact will their choice have on the existing multicast design?


A customer is using a service provider to provide a WAN backbone for a 30-site network.
In establishing the network, the customer must work within these constraints:
– The customer has a self-managed MPLS backbone.
– The VPLS WAN backbone of the service provider does not support PIM snooping.
– Multicast VPN must be used for multicast support inside some VRFs.
What can the customer do so that multicast traffic is NOT flooded to all sites?


What are two design advantages to using virtual port channel? (Choose two.)


What are three key design principles when using a classic hierarchical network model? (Choose three.)


Which three techniques can be used to improve fault isolation in an enterprise network design? (Choose three.)


When you design a network, when would it be required to leak routes into a Level 1 area?


What are two benefits of following a structured hierarchical and modular design? (Choose two.)


In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers.
How would you redesign the network to improve stability?


During a network design review, it is recommended that the network with a single large area should be broken up into a backbone and multiple nonbackbone areas. There are differing opinions on how many ABRs are needed for each area for redundancy.
What would be the impact of having additional ABRs per area?


A large enterprise customer is migrating thousands of retail offices from legacy TDM circuits to an Ethernet-based service. The network is running OSPF and has been stable for many years. It is now possible to backhaul the circuits directly to the data centers, bypassing the regional aggregation routers.
Which two networking issues need to be addressed to ensure stability with the new design? (Choose two.)
