Refer to the exhibit.

Which two options provide the best loop protection in this topology, regardless of a bridged
domain configuration? (Choose two.)

Which three factors slow down network convergence? (Choose three.)

You are designing a core MPLS-based network with a single OSPF area with no external routes.
Which two mechanisms can be used to improve convergence time during a failure? (Choose
two.)

Refer to the exhibit.Company A is running a single-area OSPF, and Company B is running RIP as the IGP with no
overlapping IP address spaces. Company A has just acquired Company B and both networks
must be merged. Which three design components are recommended to guarantee connectivity
and redundancy between the two networks? (Choose three.)

Youare working on a network design for Customer A. This design should consider fast
convergence features, and it was agreed that BFD should be used for faster link-transition
detection. Which three options apply to the use of the echo function in BFD? (Choose three.)

The Customer X 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. The customer engineering department has some questions about
the use of the Overload Bit in the IS-IS networks and how it could be used to improve their
current network design. Which three options about the Overload Bit are true? (Choose three.)

Refer to the exhibit.

Four customer sites are connected through an EoMPLS-based VPLS over an MPLS provider.You
are migrating from OSPF to multi-level IS-IS as the routing protocol to run on the four CE
routers, and connectivity between all four sites is required. Youwant to control which CE or CEs
will be elected as the Designated Intermediate System. Which two key aspects should be taken
into account? (Choose two.)

To improve the stability of a global network, you have been tasked with changing the design to
include link-state topology summarization. What are two issues that you should address as part
of the design? (Choose two.)

Which two statements describe how including Cisco IPoDWDM proactive protection in an
optical design would minimize packet loss in the event of a fiber cut? (Choose two).

A customer wants to understand the benefits of a proposed network design that utilizes
SNMPv3. Which two network threats is SNMPv3 effective against? (Choose two.)
