EIGRP
IS-IS
BGP
OSPF
RIPng
Question 42
Which two steps can be taken to improve convergence in an OSPF network? (Choose two.)
Use Bidirectional Forwarding Detection
Merge all the areas into one backbone area
Tune OSPF parameters
Make all non-backbone areas stub areas
Span the same IP network across multiple areas.
Question 43

All configured VLANs must be grouped in two SIP instances. Which standards-based Spanning Tree technology supports this design solution?
MSTP
RSTP
Rapid PVST
STP
Question 44
Which control-plane technology allows the same subnet to exist across multiple network locations?
LISP
VXLAN
FabricPath
ISE mobility services

Question 45
Which two statements describe source trees in a multicast environment? (Choose two.)
Source trees guarantee the minimum amount of network latency for forwarding multicast traffic
Source trees create an optimal path between the source and the receivers
Source trees use a single common root placed at some chosen point in the network
Source trees can introduce latency in packet delivery
Source trees can create suboptimal paths between the source and the receivers

Question 46
A customer with an IPv4 only network topology wants to enable IPv6 connectivity while preserving the IPv4 topology services. The customer plans to migrate IPv4 services to the IPv6 topology, then decommission the IPv4 topology. Which topology supports these requirements?
dual stack
6VPE
6to4
NAT64
Question 47
A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link. Which approach achieves this goal and does not impact router CPU utilization?
Utilize BFD and tune the multiplier to 50
Lower the BGP hello interval
Decrease the BGP keepalive timer
Utilize BFD and keep the default BGP timers
Question 48
An engineer is working with NETCONF and Cisco NX-OS based devices. The engineer needs a YANG model that supports a specific feature relevant only to Cisco NX-OS. Which model must the engineer choose?
Native
IEEE
OpenConfig
IETF

Question 49
What is the purpose of an edge node in an SD-Access network fabric?
Edge nodes identify and authenticate endpoints and register endpoint information with control plane nodes.
Edge nodes track endpoint IDs to location mappings, along with IPv4, IPv6, or MAC addresses.
Edge nodes are the gateway between the fabric domain and network outside of the fabric.
Edge nodes resolve lookup requests from edge and border nodes to locate destination endpoint IDs.
Question 50
Which OSPF area blocks LSA Type 3, 4 and 5, but allows a default summary route?
normal
stub
NSSA
totally stubby
