Which two mechanisms ensure that a network design provides fast path failure detection?
(Choose two.)

Refer to the exhibit.Your junior design engineer presents this configuration design. What is the next-hop router for
CE3, and why?

A service provider creates a network design that runs MPLS in its WAN backbone using OSPF as
the IGP routing protocol. What would be two effects of additionally implementing MPLS-TE?
(Choose two.)

A company requests that you consult with them regarding the design of their production,
development, and test environments. They indicate that the environments must communicate
effectively,but they must be kept separate due to the inherent failures on the development
network. What will be configured on the links between the networks to support their design
requirements?

Refer to the exhibit.How would you adjust the design to improve convergence on the network?

Refer to the exhibit.The design is being proposed for use within the network. The CE devices are OSPF graceful
restart-capable, and the core devices are OSPF graceful restart-aware. The WAN advertisements
received from BGP are redistributed into OSPF. A forwarding supervisor failure event takes
place on CE A. During this event, how will the routes learned from the WAN be seen on the
core devices?

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.)

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?

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?

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