1. Question 121 · 504 in bank

   A customer has a requirement for an automation solution that supports periodically acquiring configuration from a centralized server and aligning UCS servers to their desired state. Which open-source tool meets this requirement?

   • ASaltStack
   • BKubernetes
   • CPuppet
   • DTerraform

   Show answer

   Answer: C

   Explanation

   The Puppet software package, developed by Puppet Labs, is an open source automation toolset for managing servers and other resources by enforcing device states, such as configuration settings. Puppet components include a puppet agent which runs on the managed device (node) and a puppet master (server) that typically runs on a separate dedicated server and serves multiple devices. The operation of the puppet agent involves periodically connecting to the puppet master; which in turn compiles and sends a configuration manifest to the agent; the agent reconciles this manifest with the current state of the node and updates state based on differences.

   • ARMON
   • BEEM
   • CCall Home

   Show answer

   Answer: B

   Explanation

   EEM consists of three major components: ✑ Event statements ג€" Events to monitor from another Cisco NX-OS component that may require some action, workaround, or notification. ✑ Action statements ג€" Actions that EEM can take, such as sending an e-mail, or disabling an interface, to recover from an event. ✑ Policies ג€" A combination of an event statement and an action statement. When the specified event occurs, the configured action is executed.

   What is an advantage of using Ansible for automation as compared to Puppet and Chef?

   • AAnsible performs automation without installing a software agent on the target node.
   • BAnsible abstracts a scenario so that one set of configuration settings can be used across multiple operating systems.
   • CAnsible automates the enforcement of configuration settings.
   • DAnsible configures a set of CLI commands on a device by using NETCONF.

   Show answer

   Answer: A

   Explanation

   Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. Designed for multi-tier deployments since day one, Ansible models your IT infrastructure by describing how all of your systems inter-relate, rather than just managing one system at a time. It uses no agents and no additional custom security infrastructure, so it's easy to deploy - and most importantly, it uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to describe your automation jobs in a way that approaches plain English.

   What are two capabilities of the Cisco Network Assurance Engine? (Choose two.)

   • AIt validates that devices comply with network security policies.
   • BIt predicts the impact of changes to the network.
   • CIt predicts the network load on a data center.
   • DIt ensures that network performance meets an SLA.
   • EIt verifies the speed of network packet flows by using telemetry.

   Show answer

   Answer: AB

   Explanation

   With Cisco Network Assurance Engine operators can: ג— Predict the impact of network changes: Proactively verify changes made to the network for correctness to drive increased change agility while significantly reducing the risk of network failures induced by human error. ג— Verify network-wide behavior: Continuously analyze and verify the dynamic state of the network against intent and policy to ensure connectivity and eliminate potential network outages and vulnerabilities before any business impact occurs. ג— Ensure network security policy and compliance: Ensure network security policies and check for compliance against business rules to reduce security risk and achieve provable continuous compliance by policy and state.

   What is required for using Puppet in a Cisco NX-OS environment?

   • AOpenNP
   • BXML management interface
   • CNX-API
   • DOpen Agent Container

   Show answer

   Answer: D

   Explanation

   Puppet agents cannot run natively on Cisco Nexus 7000 and Cisco Nexus 7700 switches. Instead, they run in a special virtual environment called the Open Agent Container (OAC).

7. Question 127 · 504 in bank

   Refer to the exhibit.

   

   Why does the Python code for Cisco NX-API print an error message?

   • AThe JSON is not a supported format for the NX-API.
   • BThe "type" is wrong in the header of the request and should be "cli_conf"
   • CNX-API does not allow configuration for features via the requests module.
   • DThe "type" is wrong in the body of the request and should be "cli_conf"

   Show answer

   Answer: D

   Explanation

   D Seems to be right. "Commands that belong to different message types should not be mixed. For example, show commands are cli_show message type and are not supported in cli_conf mode." https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus7000/sw/programmability/guide/cisco_nexus7000_programmability_guide_8x/b-cisco-nexus7000-programmability-guide-8x_chapter_011.html

   A POAP-enabled Cisco Nexus switch will not enter POAP mode. Which two conditions should be verified? (Choose two.)

   • ANo startup configuration is available.
   • BThe switch is in bootup process.
   • CThe license file is missing on the switch.
   • DBootflash must contain a special directory named POAP with poap.py file.
   • ENo Cisco NX-OS image is present on the bootflash.

   Answer: AB

   Explanation

   https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/fundamentals/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_Fundamentals_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_Fundamentals_Configuration_Guide_7x_chapter_0100.html#concept_88533D1764C843189A825D54B9FA9E7D C is Correct: The POAP feature does not require a license and is enabled by default. However for the POAP feature to function, appropriate licenses must be installed on the devices in the network before the deployment of the network. E is also Correct : The switch software image must support POAP for this feature to function. A cant be an answer becuase thats why Switch Goes to POAP "When a device with the POAP feature boots and does not find the startup configuration, the device enters POAP mode, locates a DHCP server...(output omitted) and B doesnt make any sense. and i havent found anything on D So Correct ans is C & E

10. Question 130 · 504 in bank

    An engineer enters these commands while in EEM on a Cisco Nexus 9000 Series Switch event manager applet Backup-config event timer watchdog time 1800 name timer event cli match "copy running-config startup-config" What is the result of applying this configuration?

    • AIt generates an error because no action is mentioned.
    • BIt executes the copy running-config startup-confing command.
    • CIt saves the running configuration every 1800 seconds.
    • DIt blocks the copy running-config startup-config command.

    Show answer

    Answer: D

    Explanation

    Isn't it D? From the book "If you want to allow the triggered event to process any default actions, you must configure the EEM policy to allow the default action. For example, if you match a CLI command in a match statement, you must add the event-default action statement to the EEM policy; otherwise, EEM will not allow the CLI command to execute."
