Question 2

An engineer just completed the installation of Cisco NSO and all of its components. During testing, some of the services are not working properly. To resolve the issue, the engineer started undeploying service instances. What can this cause?

AIt removes the service configuration from the network device only.

BIt removes the service configuration from the network and NSO.

CIt removes the service configuration from NSO only.

DIt runs the service code again when the device is out of sync.

Question 3

You create a simple service package skeleton in Cisco NSO using ncs-make-package --service-skeleton template vlan. Which two steps must be performed to complete the service? (Choose two.)

ACreate the VLAN service template in XML.

BModify the VLAN FastMap algorithm.

CStart the VLAN Python VM.

DCreate the VLAN service model in YANG.

ECompile the VLAN NED.

Answer : D, E

Question 4

Refer to the exhibit.

An engineer updated the skeleton template. How can a device be entered into the YANG Model?

AModify the device instance of the device by referencing the acl_lab variable from our YANG model.

BDeploy a service instance that configures a VLAN of all of the devices present in Cisco NSO.

CDeploy a service instance that configures a VLAN of a list of devices referenced to the service YANG model.

DModify the device instance by referencing the device variable from our YANG model.

Answer : D

Question 5

How does using the Python with statement in conjunction with ncclient manager improve an existing NETCONF automation script?

AIt allows the NETCONF connection to the device to be gracefully closed without having to explicitly code this action.

BIt manages the running configuration of the device by comparing it to the new configuration applied using NETCONF.

CThe with statement tries to connect to the device using TCP port 830 first but also tries to connect via TCP port 22.

DUse of the with statement catches any exceptions when trying to connect to a device using NETCONF.

Answer : D

Question 6

What are two benefits of using Cisco NSO? (Choose two.)

AIt abstracts the device adapter and complex device logic from the service logic.

BIt uses load balancing services for better traffic distribution.

CIt easily integrates into northbound systems and APIs.

Question 7

Refer to the exhibit.

What is the effect of the script on the device?

AAll interfaces except GigabitEthernet2 are reset to their default configurations.

BIt replaces the entire configuration for GigabitEthernet2 on the device using RESTCONF.

CIt merges the new configuration with the existing configuration on the device using RESTCONF.

DIt compares the configuration to the device. If it matches, the device sends back an HTTP 204 status code.
