Question 101.<\/b><\/p>\n

Which Cisco Intersight capability can be used to automate infrastructure operations through programmable APIs?<\/b><\/p>\n

    \n
  1. <\/b> REST API<\/span>
    \n<\/span>2.<\/b> CDP only<\/span>
    \n<\/span>3.<\/b> STP only<\/span>
    \n<\/span>4.<\/b> VTP only<\/span><\/li>\n<\/ol>\n

    Correct Answer: 1<\/b><\/p>\n

    Explanation:<\/b><\/p>\n

    Cisco Intersight provides REST APIs that allow automation systems to query inventory, manage supported infrastructure resources, apply policies, and integrate with external workflows. This makes it suitable for programmatic infrastructure management and orchestration. Technologies such as CDP, STP, and VTP are networking features and are not general-purpose management APIs. When building Intersight automation, developers should understand authentication, resource identifiers, pagination, filtering, and response handling. API credentials should be protected carefully because they may provide significant management access to infrastructure.<\/span><\/p>\n

    Question 102.<\/b><\/p>\n

    What is the main advantage of using API filters when querying a large infrastructure inventory?<\/b><\/p>\n

      \n
    1. <\/b> They disable authentication<\/span>
      \n<\/span>2.<\/b> They reduce the amount of unnecessary data returned<\/span>
      \n<\/span>3.<\/b> They automatically modify resources<\/span>
      \n<\/span>4.<\/b> They eliminate pagination in every case<\/span><\/li>\n<\/ol>\n

      Correct Answer: 2<\/b><\/p>\n

      Explanation:<\/b><\/p>\n

      API filters allow a client to request only records that match specified criteria, such as a device name, status, model, or organization. This can significantly reduce response size and processing overhead when an environment contains hundreds or thousands of objects. Filtering does not remove authentication requirements and does not necessarily eliminate pagination if many matching records remain. It also does not modify resources unless the API operation explicitly performs a change. Efficient filtering helps automation scripts scale and reduces unnecessary network and controller load.<\/span><\/p>\n

      Question 103.<\/b><\/p>\n

      Which API mechanism should a client use when the server returns a continuation token indicating that more records are available?<\/b><\/p>\n

        \n
      1. <\/b> Authentication reset<\/span>
        \n<\/span>2.<\/b> Resource deletion<\/span>
        \n<\/span>3.<\/b> Pagination<\/span>
        \n<\/span>4.<\/b> Session termination<\/span><\/li>\n<\/ol>\n

        Correct Answer: 3<\/b><\/p>\n

        Explanation:<\/b><\/p>\n

        A continuation token is commonly used as part of API pagination. The client includes the token in a subsequent request to retrieve the next set of records. This approach is often preferable to fixed page numbers because it allows the server to manage large result sets efficiently. Automation that ignores continuation tokens may process only a subset of the available inventory. Authentication, deletion, and session termination are unrelated to retrieving additional result pages. Reliable scripts should continue following pagination information until all required records have been collected.<\/span><\/p>\n

        Question 104.<\/b><\/p>\n

        Which HTTP response class generally indicates that a request was successfully processed?<\/b><\/p>\n

          \n
        1. <\/b> 1xx<\/span>
          \n<\/span>2.<\/b> 3xx<\/span>
          \n<\/span>3.<\/b> 4xx<\/span>
          \n<\/span>4.<\/b> 2xx<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4<\/b><\/p>\n

          Explanation:<\/b><\/p>\n

          HTTP status codes in the 2xx range indicate successful request processing. Examples include 200 OK, 201 Created, and 204 No Content. Codes in the 4xx range indicate client-side problems such as invalid authentication, authorization failure, or missing resources, while 5xx codes represent server-side failures. The 3xx range generally relates to redirection, and 1xx represents informational responses. Automation should evaluate specific response codes rather than assuming that every non-error transport connection means the API action succeeded.<\/span><\/p>\n

          Question 105.<\/b><\/p>\n

          A Python API call receives HTTP status code 429. What should the script do?<\/b><\/p>\n

            \n
          1. <\/b> Respect the rate limit and retry later using controlled backoff<\/span>
            \n<\/span>2.<\/b> Immediately send requests as fast as possible<\/span>
            \n<\/span>3.<\/b> Disable TLS<\/span>
            \n<\/span>4.<\/b> Assume the resource was deleted<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation:<\/b><\/p>\n

            HTTP 429 indicates that the client has sent too many requests in a given period. The appropriate response is to reduce request frequency and retry later, ideally using any <\/span>Retry-After<\/span> value supplied by the API. Controlled backoff helps prevent the client from making the problem worse. Repeated rapid requests can extend throttling or place additional load on the service. Disabling TLS is unrelated and weakens security. The response does not indicate that the resource was deleted. Rate-limit handling is especially important when automating large inventories.<\/span><\/p>\n

            Question 106.<\/b><\/p>\n

            Which Python structure is best suited for storing key-value pairs returned from a parsed JSON object?<\/b><\/p>\n

              \n
            1. <\/b> Set<\/span>
              \n<\/span>2.<\/b> Dictionary<\/span>
              \n<\/span>3.<\/b> Tuple only<\/span>
              \n<\/span>4.<\/b> Integer<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2<\/b><\/p>\n

              Explanation:<\/b><\/p>\n

              A Python dictionary stores key-value pairs and maps naturally to a JSON object. For example, a JSON response containing a device name, serial number, and status can be represented as a dictionary and accessed by keys. JSON arrays normally map to Python lists. Sets and tuples can be useful in other situations but are not the direct equivalent of JSON objects. Understanding these mappings is important because infrastructure APIs often return deeply nested JSON structures that scripts must traverse and validate before making decisions.<\/span><\/p>\n

              Question 107.<\/b><\/p>\n

              Which Python technique is most appropriate for processing every device returned in a list from an API response?<\/b><\/p>\n

                \n
              1. <\/b> Exception only<\/span>
                \n<\/span>2.<\/b> Import only<\/span>
                \n<\/span>3.<\/b> for loop<\/span>
                \n<\/span>4.<\/b> Class decorator only<\/span><\/li>\n<\/ol>\n

                Correct Answer: 3<\/b><\/p>\n

                Explanation:<\/b><\/p>\n

                A <\/span>for<\/span> loop is the natural choice for iterating through a list of device records. Each iteration can inspect one device, extract attributes, compare its state with policy, or issue follow-up API requests. This makes automation scalable and avoids repetitive code. Exceptions handle failures, while imports load modules. Decorators modify function or class behavior but are not the basic mechanism for processing each item in a list. Loops should be combined with error handling so a failure on one device does not necessarily stop the entire workflow.<\/span><\/p>\n

                Question 108.<\/b><\/p>\n

                What is the main benefit of using a Python function for repeated API authentication logic?<\/b><\/p>\n

                  \n
                1. <\/b> It disables credential expiration<\/span>
                  \n<\/span>2.<\/b> It removes the need for error handling<\/span>
                  \n<\/span>3.<\/b> It guarantees API availability<\/span>
                  \n<\/span>4.<\/b> It reduces duplicated code and improves maintainability<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 4<\/b><\/p>\n

                  Explanation:<\/b><\/p>\n

                  Placing repeated authentication logic in a function allows the same code to be reused wherever authentication is required. This makes the script easier to maintain because changes to headers, token handling, or endpoint URLs can be made in one place instead of many. Functions do not prevent credential expiration, eliminate errors, or guarantee controller availability. Well-structured functions also make unit testing easier. In production automation, reusable functions for authentication, requests, validation, and logging can significantly improve code quality.<\/span><\/p>\n

                  Question 109.<\/b><\/p>\n

                  Which Python block is used to catch an exception raised inside a <\/b>try<\/b> statement?<\/b><\/p>\n

                    \n
                  1. <\/b> except<\/span>
                    \n<\/span>2.<\/b> with<\/span>
                    \n<\/span>3.<\/b> for<\/span>
                    \n<\/span>4.<\/b> lambda<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 1<\/b><\/p>\n

                    Explanation:<\/b><\/p>\n

                    The <\/span>except<\/span> block catches exceptions raised during execution of code inside a <\/span>try<\/span> block. Automation can use this to handle connection errors, invalid JSON, authentication failures, timeouts, or other expected problems. Specific exceptions should be caught where possible so the script can respond appropriately. A broad catch-all may hide useful diagnostic information. The <\/span>with<\/span> statement manages contexts, <\/span>for<\/span> performs iteration, and <\/span>lambda<\/span> defines an anonymous function. Exception handling is central to creating resilient infrastructure automation.<\/span><\/p>\n

                    Question 110.<\/b><\/p>\n

                    Which Python statement should be used to deliberately stop execution because a critical validation check failed?<\/b><\/p>\n

                      \n
                    1. <\/b> continue<\/span>
                      \n<\/span>2.<\/b> raise<\/span>
                      \n<\/span>3.<\/b> pass<\/span>
                      \n<\/span>4.<\/b> import<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 2<\/b><\/p>\n

                      Explanation:<\/b><\/p>\n

                      The <\/span>raise<\/span> statement can deliberately generate an exception when the script detects an unsafe or invalid condition. For example, a script might stop if it discovers that a production tenant name does not match the expected environment before performing deletion. <\/span>continue<\/span> skips to the next loop iteration, <\/span>pass<\/span> performs no action, and <\/span>import<\/span> loads modules. Explicit exceptions help make automation fail safely instead of silently continuing after a critical validation problem.<\/span><\/p>\n

                      Question 111.<\/b><\/p>\n

                      Which Ansible keyword is used to save the result of a task for later evaluation?<\/b><\/p>\n

                        \n
                      1. <\/b> register<\/span>
                        \n<\/span>2.<\/b> hosts<\/span>
                        \n<\/span>3.<\/b> vars<\/span>
                        \n<\/span>4.<\/b> roles only<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 1<\/b><\/p>\n

                        Explanation:<\/b><\/p>\n

                        The <\/span>register<\/span> keyword stores a task’s result in a variable. Later tasks can inspect the result to determine whether an operation succeeded, what data was returned, or whether another action is needed. For example, a playbook can query a Nexus switch, register the output, and then use a conditional based on the returned value. <\/span>hosts<\/span> defines the target systems, while <\/span>vars<\/span> defines values and roles organize reusable content. Registered results make playbooks more dynamic and context-aware.<\/span><\/p>\n

                        Question 112.<\/b><\/p>\n

                        Which Ansible feature is most appropriate for executing a task only when a registered result meets a specific condition?<\/b><\/p>\n

                          \n
                        1. <\/b> notify<\/span>
                          \n<\/span>2.<\/b> when<\/span>
                          \n<\/span>3.<\/b> handler only<\/span>
                          \n<\/span>4.<\/b> inventory<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 2<\/b><\/p>\n

                          Explanation:<\/b><\/p>\n

                          The <\/span>when<\/span> keyword provides conditional task execution. A playbook can evaluate a registered result and run a subsequent task only if the specified expression is true. For example, it may create a VLAN only when a previous query shows that the VLAN does not exist. This supports reusable and idempotent automation. <\/span>notify<\/span> triggers handlers, inventory defines hosts, and handlers are typically used for follow-up actions after a change. Conditionals help prevent unnecessary or inappropriate configuration changes.<\/span><\/p>\n

                          Question 113.<\/b><\/p>\n

                          Which Ansible mechanism allows the same task to run once for every interface listed in a variable?<\/b><\/p>\n

                            \n
                          1. <\/b> loop<\/span>
                            \n<\/span>2.<\/b> handler<\/span>
                            \n<\/span>3.<\/b> vault<\/span>
                            \n<\/span>4.<\/b> inventory plugin only<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 1<\/b><\/p>\n

                            Explanation:<\/b><\/p>\n

                            An Ansible loop repeats a task for each item in a list. If an interface list contains several entries, one task can configure each interface using the current loop item rather than duplicating YAML. This improves maintainability and makes playbooks easier to adapt to different devices. Handlers respond to notifications, Vault protects secrets, and inventory plugins manage target discovery. Loops are particularly useful when data center configurations contain repeated structures such as VLANs, interfaces, policies, or endpoint groups.<\/span><\/p>\n

                            Question 114.<\/b><\/p>\n

                            Which Ansible feature should be used to protect sensitive variables such as API passwords when they must be stored with automation content?<\/b><\/p>\n

                              \n
                            1. <\/b> callback plugin<\/span>
                              \n<\/span>2.<\/b> Ansible Vault<\/span>
                              \n<\/span>3.<\/b> fact cache<\/span>
                              \n<\/span>4.<\/b> inventory group<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 2<\/b><\/p>\n

                              Explanation:<\/b><\/p>\n

                              Ansible Vault encrypts sensitive variables and files so passwords, tokens, and other secrets are not stored as readable plaintext in repositories. Organizations may also integrate external secret-management platforms for centralized control and rotation. Vault does not eliminate the need for least privilege, secure key handling, or access control. Callback plugins affect execution output, fact caches store gathered information, and inventory groups organize hosts. Protecting automation secrets is essential because exposed credentials may provide privileged infrastructure access.<\/span><\/p>\n

                              Question 115.<\/b><\/p>\n

                              Which Terraform command should be used to preview resource changes before applying them?<\/b><\/p>\n

                                \n
                              1. <\/b> terraform plan<\/span>
                                \n<\/span>2.<\/b> terraform destroy<\/span>
                                \n<\/span>3.<\/b> terraform output only<\/span>
                                \n<\/span>4.<\/b> terraform graph only<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 1<\/b><\/p>\n

                                Explanation:<\/b><\/p>\n

                                terraform plan<\/span> shows the actions Terraform intends to take to move infrastructure from its current state to the desired configuration. It identifies resources that will be created, changed, replaced, or destroyed. Reviewing this output before an apply is an important production safeguard because it can expose unintended changes. <\/span>terraform destroy<\/span> removes resources, while <\/span>output<\/span> and <\/span>graph<\/span> serve different informational purposes. A plan should be reviewed carefully whenever high-impact infrastructure resources are involved.<\/span><\/p>\n

                                Question 116.<\/b><\/p>\n

                                Which Terraform command performs the changes shown in an approved execution plan?<\/b><\/p>\n

                                  \n
                                1. <\/b> terraform fmt<\/span>
                                  \n<\/span>2.<\/b> terraform validate<\/span>
                                  \n<\/span>3.<\/b> terraform providers<\/span>
                                  \n<\/span>4.<\/b> terraform apply<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 4<\/b><\/p>\n

                                  Explanation:<\/b><\/p>\n

                                  terraform apply<\/span> executes the infrastructure changes required to reach the desired state. In production, it should generally follow validation and plan review. Terraform may create, update, replace, or delete resources depending on the configuration and state. <\/span>terraform fmt<\/span> standardizes formatting, while <\/span>terraform validate<\/span> checks configuration consistency. Because an apply can make broad changes quickly, access controls, approval gates, remote state, and backups or rollback strategies are important components of a mature infrastructure-as-code workflow.<\/span><\/p>\n

                                  Question 117.<\/b><\/p>\n

                                  Which Terraform feature helps prevent simultaneous processes from modifying the same state when supported by the backend?<\/b><\/p>\n

                                    \n
                                  1. <\/b> State locking<\/span>
                                    \n<\/span>2.<\/b> Route locking<\/span>
                                    \n<\/span>3.<\/b> VLAN locking<\/span>
                                    \n<\/span>4.<\/b> Packet locking<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 1<\/b><\/p>\n

                                    Explanation:<\/b><\/p>\n

                                    State locking prevents two Terraform processes from modifying the same state at the same time. This helps avoid race conditions, conflicting updates, and potential state corruption. Many remote backends support locking automatically during operations. State locking does not replace source-control coordination or change approval, but it provides protection at execution time.

                                      Correct Answer: 2<\/b><\/p>\n

                                      Explanation:<\/b><\/p>\n

                                      NETCONF provides structured network management using RPC operations and commonly runs over SSH. It works with YANG data models and can retrieve or modify configuration and operational state. Depending on platform capabilities, NETCONF can support operations involving running, candidate, or startup datastores, as well as locking and commit behavior. FTP and TFTP transfer files, while Syslog transports event messages. NETCONF is valuable because its structured interface reduces reliance on parsing human-oriented CLI output.<\/span><\/p>\n

                                        Correct Answer: 1<\/b><\/p>\n

                                        Explanation:<\/b><\/p>\n

                                        RESTCONF provides HTTP-based access to YANG-modeled configuration and operational data. Clients can use familiar web methods such as GET, POST, PUT, PATCH, and DELETE as supported by the implementation. Data is commonly represented using JSON or XML. RESTCONF combines REST-style interaction with model-driven networking. CDP, STP, and HSRP are network control or discovery protocols and do not provide general YANG-based configuration interfaces.<\/span><\/p>\n

                                        Question 120.<\/b><\/p>\n

                                        A development team wants every proposed automation change to undergo syntax checks, unit tests, and policy validation before being merged. Which workflow best supports this requirement?<\/b><\/p>\n

                                          Correct Answer: 3<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          A continuous integration pipeline can automatically validate every proposed change before it is merged. The pipeline may run Python unit tests, lint YAML, validate Terraform, inspect templates, check security policies, and verify coding standards. This catches defects earlier and provides consistent quality controls across the team. Source-control review and approval can be layered on top of automated checks. Direct production changes bypass these safeguards, while placing secrets in repositories creates serious security risk. CI is therefore a core practice for reliable infrastructure automation.<\/span><\/p>\n
