Drag and drop the characteristics from the left onto the YANG modules they describe on the right. Not all options are used.
A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their
data center. An architect must design a new solution to improve availability and reduce
costs while keeping these considerations in mind:
» The company uses multicast to deliver training to the stores.
» The company uses dynamic routing protocols and has implemented QoS.
» To simplify deployments, tunnels should be created dynamically on the hub when
additional stores open.
Which solution should be included in this design?
A.
VPLS
B.
GET VPN
C.
DMVPN
D.
IPsec

An engineer must design a multicast network for a financial application. Most of the
multicast sources also receive multicast traffic (many-to-many deployment model). To
better scale routing tables, the design must not use source trees. Which multicast protocol
satisfies these requirements?
A.
PIM-SSM
B.
PIM-SM
C.
MSDP
D.
BIDIR-PIM

Bidir-PIM is designed to be used for many-to-many applications within individual PIM
domains. Multicast groups in bidirectional PIM mode can scale to an arbitrary number of
sources without incurring overhead due to the number of sources.

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?
A.
Native
B.
IEEE

What is the purpose of an edge node in an SD-Access network fabric?
A.
Edge nodes identify and authenticate endpoints and register endpoint information with control plane nodes.
B.
Edge nodes track endpoint IDs to location mappings, along with IPv4, IPv6, or MAC
addresses.
C.
Edge nodes are the gateway between the fabric domain and network outside of the fabric.
D.
Edge nodes resolve lookup requests from edge and border nodes to locate destination endpoint IDs.
Edge nodes identify and authenticate endpoints and register endpoint information with control plane nodes.

A customer is running HSRP on the core routers. Over time the company has grown and
requires more
network capacity. In the current environment, some of the downstream interfaces are
almost fully utilized, but
others are not. Which solution improves the situation?
A.
Make router R2 active for half of the VLANs.
B.
Add more interfaces to R1 and R2.
C.
Configure port channel toward downstream switches.
D.
Enable RSTP on the downstream switches.
Make router R2 active for half of the VLANs.
Which nonproprietary mechanism can be used to automate rendezvous point distribution in
a large PIM domain?
A.

C.
Auto-RP
D.
Static RP

A network engineer is designing a network for AS100. The design should ensure that all traffic enters AS100 via link 1 unless there is a network failure. In the event of a failure, link 2 should function as the path for incoming traffic. Which solution should the design include?
A.
Modify the next-hop attribute on R3.
B.
Use AS-Path prepending on R3.
C.
Modify the next-hop attribute on R4.
D.
Use AS-Path prepending on R4
Use AS-Path prepending on R4
An infrastructure team is concerned about the shared memory utilization of a device, and
for this reason, they need to monitor the device state. Which solution limits impact on the
device and provides the required data?
A.
IPFIX
B.
static telemetry
C.
on-change subscription
D.
periodic subscription
on-change subscription
Explanation: There are two types of subscriptions: periodic and on-change. With periodic
subscription, data is streamed out to the destination at the configured interval. It
continuously sends data for the lifetime of that subscription. With on-change, data is
published only when a change in the data occurs such as when an interface or OSPF
neighbor goes down. https://developer.cisco.com/docs/ios-xe/#!streaming-telemetry-quickstart-

An engineer is creating a design to enable IPv6 to run on an existing IPv4 IS-IS network.
The IPv4 and IPv6 topologies will match exactly, and the engineer plans to use the same
router levels for each protocol per interface. Which IS-IS design is required?
A.
single topology without enabling transition feature
B.
single topology with transition feature enabled
C.
multi topology with transition feature enabled
D.
multi topology without enabling transition feature
multi topology with transition feature enabled
