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?

Refer to the exhibit.

You are designing a spanning-tree network for a small campus. Which two of these options
would result in a trouble-free spanning-tree network design? (Choose two.)

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 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?

Refer to the exhibit.

A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures
between SP-SW1 and SP-SW2. In which two of these ways can you design this solution?(Choose two.)

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.)
