   An engineer needs to automate the configuration on a Cisco NX-OS switch. The solution must meet these requirements: • Ansible is used. • The transport protocol is encrypted. • Support for Asynchronous requests. Which two access mechanisms must be used? (Choose two.)

   • AJSON-RPC
   • BNX-API
   • CHTTPS
   • DSNMP Version 2c
   • ENETCONF

   Show answer

   Answer: BC

   Explanation

   NX-API uses HTTP/HTTPS as its transport. CLIs are encoded into the HTTP/HTTPS POST body. Starting with Cisco NX-OS Release 9.2 (1), the NX-API feature is enabled by default on HTTPS port 443. HTTP port 80 is disabled. NX-API is also supported through UNIX Domain Sockets for applications running natively on the host or within Guest Shell. https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/102x/programmability/cisco-nexus-9000-series-nx-os-programmability-guide-release-102x/m-n9k-nx-api-cli-101x.html#:~:text=NX-API%20uses%20HTTP%2FHTTPS%20as%20its%20transport.%20CLIs%20are,natively%20on%20the%20host%20or%20within%20Guest%20Shell.

   Which solution is used to manage automatic dependencies on a Cisco NCS device using Cisco IOS XR Software?

   • Apeer code reviews
   • BCI/CD pipelines
   • Cflexible packaging
   • Dautomated deployments

   Show answer

   Answer: C

   Explanation

   The answer is C. flexible packaging. Flexible packaging is a feature of Cisco IOS XR Software that allows you to package software images and dependencies together. This makes it easier to manage the dependencies of software images and to deploy them to Cisco NCS devices.

   Select 2

   

   Refer to the exhibit. An application design has been proposed for a new infrastructure monitoring system that collects telemetry from infrastructure devices and visualizes it on a dashboard from a central database. Because of constraints regarding available compute and storage at local sites, the decision has been made to implement a hybrid application design. Which two changes must be made to the application architecture to improve the high availability and resiliency of the application, specifically to ensure minimal data loss of measurement data that is being collected periodically? (Choose two.)

   • AImplement caching to reduce the amount of data that is sent from the cloud to local sites.
   • BImplement certificates to ensure that data collection nodes are trusted sources in the application.
   • CImplement local storage at the data collection layer in case of connectivity loss to the cloud.
   • DEnsure that the database is replicated across multiple different cloud regions.
   • EImplement a redundant network at the local sites.

   Show answer

   Answer: CD

   Explanation

   C. Implement local storage at the data collection layer in case of connectivity loss to the cloud. D. Ensure that the database is replicated across multiple different cloud regions. Implementing local storage at the data collection layer can ensure that data is not lost in case of a sudden loss in connectivity. This ensures high availability and resiliency as data can be stored and then sent once connectivity is restored. Additionally, replicating the database across multiple different cloud regions ensures that even if one region experiences an issue, the data is still available in another region. This adds an extra layer of security and ensures minimal data loss.

   Given an application that implements a basic search function as well as a video upload function, which two load-balancing approaches optimize the application's user experience? (Choose two.)

   • AVideo upload requests should be routed to the endpoint using an intermediate hop.
   • BSearch requests should be routed to the endpoint with lowest round-trip latency.
   • CVideo upload requests should be routed to the endpoint with lowest round-trip latency.
   • DVideo upload requests should be routed to the endpoint with highest data throughput.
   • ESearch requests should be routed to the endpoint with highest data throughput.

   Show answer

   Answer: BD

   Explanation

   Definitely BD. Search doesn't need high throughput. It needs to be fast (low latency). Video doesn't need a fast connection, it needs high bandwidth so it can upload a lot of data.

    A software developer is designing a new application to collect data from the network and feed the data into a custom dashboard. The application must be easy to troubleshoot and scale. What are two reasons the developer must use modularity in the design for maintainability instead of a single code base that involves dependencies? (Choose two.)

    • Amakes the application operate faster
    • Bapplication becomes more flexible and extendable
    • Ccode reusability increases
    • Dbetter integration with public cloud services
    • Esoftware configuration management is easier

    Show answer

    Answer: BC

    Explanation

    B. Application becomes more flexible and extendable. C. Code reusability increases. Modularity in software design results in an application that is more flexible and extendable. This means that modules can be added, removed, or modified without affecting the functionality of other parts of the application, which makes the application easier to maintain and scale. Code reusability is also a significant advantage of modular design. When code is broken down into modules, those modules can be reused in other parts of the application or even in other applications. This not only speeds up development time but also leads to improved consistency and less redundancy in the code base.
