Question 141
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 toCisco NX-OS. Which model should the engineer choose?
A. Native
B. IEEE
C. OpenConfig
D. IETF
Question 142
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?
A. Updates that contain changes within the data are sent only when changes occur.
B. Empty data subscriptions do not generate empty update notifications.
C. Periodic updates include a full copy of the data that is subscribed to.
D. The primary push update is sent immediately and cannot be delayed.
Question 143
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
Question 144
An engineer uses Postman and YANG to configure a router with:
- OSPF process ID 400
- network 192.168.128.128/25 enabled for Area 0
Which get-config reply verifies that the model set was designed correctly?
A.
B.
C.
D.
Question 145

Question 146
A company must automate a set of complex changes aligned with DR testing in the network. These changes are specific, and the DR playbook will be adjusted in the future. The playbook has diverse routing and switching assets in scope as well as multiple vendor and hardware platforms. A developer will create a thin, web front-end microservice and integrate with an Open Daylight controller to push changes to the network. Which YANG model should be used?
A. Use an open YANG model to allow the reuse of code and standardize the implementation across platforms.
B. Develop an individualized YANG model to minimize development resources and time to market.
C. Use multiple native vendor YANG models to provide code consistency.
D. Use a single native vendor YANG model to minimize development time.
Question 147
An engineer uses Postman and YANG to configure a router with:
- OSPF process ID 200
- network 172.16.10.128/26 enabled for Area 0Which get-config reply verifies that the model set was designed correctly?
A.
B.
C.
D.
Question 148
An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements:
* Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times.
* A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle.
* Download traffic must never experience a delay.
Which solution must the architect choose?
A. rate-limiting and shaping
B. bandwidth percentage and policing
C. shaping and policing
D. bandwidth percentage and rate-limiting
Question 149
An engineer is designing a network for a customer running a wireless network with a common VLAN for all APs. The customer is experiencing unicast flooding in the Layer 2 network between the aggregation and access layers. The customer wants to reduce the flooding and improve convergence time. Which solution meets these requirements?
A. Migrate all APs to a common Layer 2 access layer switch and run Layer 3 from the aggregation layer to all remaining access layer switches.
B. Align HSRP primary and STP root bridges and reduce ARP timers to match CAM timers on the aggregation layer switches.
C. Migrate to a Layer 3 access campus design if the APs can run on separate VLANs.
D. Align HSRP primary and STP root bridges if the APs cannot run on separate VLANs.
Question 150
A network engineer must design a multicast solution to prevent the spoofing of multicast streams and ensure efficient bandwidth utilization. The network will be merged with another multicast domain in the future, and the merge must require minimum effort. Which two solutions meet the customer requirements? (Choose two.)
A. PIM-SSM
B. IGMPv3
C. IGMPv2
D. PIM-SM
E. MSDP
