An engineer evaluates a UI-based infrastructure management system capable of monitoring and deploying standalone VXLAN BGP EVPN deployments. The storage administrators also need the solution to manage the Cisco MDS 9000 Series Switches. Which solution meets these requirements?
Answer: A
Cisco Nexus Dashboard Fabric Controller (NDFC) (formerly DCNM) is the network management platform for all NX-OS enabled deployments. It spans new fabric architectures, storage network deployments, and IP Fabric for Media.

An engineer must implement an automation solution to allow the backup of the configuration of Cisco Nexus Series Switches to a centralized location. The solution must: * support the team-developed custom monitoring scripts that are packaged using RPM packaging that the framework must support. * be decoupled from the underlying Cisco Nexus operating system. * have no impact on the operating system of the underlying switch if the resource contention occurs. * use Python to expand the existing automation framework. Which solution meets these requirements?
Answer: A
In addition to the NX-OS CLI and Bash access on the underlying Linux environment, switches support access to a decoupled execution space running within a Linux Container (LXC) called the ג€Guest Shellג€. From within the Guest Shell the network-admin has the following capabilities: ג€¢ Access to the network over Linux network interfaces. ג€¢ Access to the switch's bootflash. ג€¢ Access to the switch's volatile tmpfs. ג€¢ Access to the switch's CLI. ג€¢ Access to Cisco NX-API REST. ג€¢ The ability to install and run python scripts. ג€¢ The ability to install and run 32-bit and 64-bit Linux applications. Decoupling the execution space from the native host system allows customization of the Linux environment to suit the needs of the applications without impacting the host system or applications running in other Linux Containers.

A company is investigating different options for IT automation tools. The IT team has experience with Python programming language and scripting using a declarative language. The proposed tool should be easy to set up and should not require installing an agent on target devices. The team will also need to build custom modules based on the Python programming language to extend the tool's functionality. Which automation tool should be used to meet these requirements?
Answer: D
An administrator is implementing DCNM so that events are triggered when monitored traffic exceeds the configured percent utilization threshold. The requirement is to configure a maximum limit of 39913690 bytes that applies directly to the statistics collected as a ratio of the total link capacity. Which DCNM performance monitoring configuration parameter must be implemented to achieve this result?
Answer: A
The Performance Manager Configuration Wizard allows you to set up two thresholds that trigger events when the monitored traffic exceeds the percent utilization configured. These event triggers can be set as either Critical or Warning events that are reported on the DCNM-SAN web client Events browser page. You must choose either absolute value thresholds or baseline thresholds that apply to all transmit or receive traffic defined in the collection. Click the Use absolute values radio button on the last screen of the Performance Manager Configuration Wizard to configure thresholds that apply directly to the statistics gathered. These statistics, as a percent of the total link capacity, are compared to the percent utilization configured for the threshold type. If the statistics exceed either configured threshold, an event is shown on the DCNM-SAN web client Events tab. As an example, the collection has absolute value thresholds set for 60% utilization (for warning) and 80% utilization (for critical). If Performance Manager detects that the traffic on a 1-Gigabit link in its collection exceeds 600 Mbps, a warning event is triggered. If the traffic exceeds 800 Mbps, a critical event is triggered.

An engineer must design an automation solution for the Cisco ACI Fabric to speed up the deployment of logical network elements for tenant provisioning. When creating a solution, the engineer must keep in mind that the tool must support these requirements: * Allow the rapid creation and removal of logical containers. * Support the creation of custom modules and data structures. * Be extensible with external libraries and modules. * Allow rapid testing of code using an on-demand execution environment. Which automation tool meets these requirements?
Answer: D

Refer to the exhibit. All switches are configured with the default OSPF priority. Which configuration should be applied to ensure that the SW2 Cisco Nexus switch controls the LSA floods and advertises the network to the remaining nodes in the OSPFv2 area?
Answer: A
The correct answer is A. A = 255 is the highest router priority B = It is the same (as we are doing nothing) C = Is not the highest router ID D = Ineligible to become the DR/BDR

DRAG DROP - Drag and drop the keywords onto the URL request to collect all the subnets configured under tenant Production using a REST API. Not all options are used. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
Since fvSubnet is a class, the answer might be: mo / query-target = subtree / target-subtree-class = fvSubnet. Cisco expect us to know all the classes? good luck with it...

An engineer must create an EPG called "Test". The configuration request should succeed if the Tenant called "Tenant" and the application profile called "Test" exist. The firewall policy allows only the HTTP connectivity to APIC from the user's computer. Which action accomplishes this goal?
Answer: B
Refer to the exhibit. An engineer logs all occurrences of a configuration being saved. The engineer must generate an additional log message when someone attempts to change the configuration for interface Ethernet 1/1. Which set of commands must be used to meet these requirements? A.
B.
C.
D.
