Question 241.

Which Cisco ACI concept defines the complete hierarchical collection of managed objects represented by APIC?

1. Management Information Tree
   2. VLAN Pool
   3. Endpoint Database only
   4. Routing Information Base

Correct Answer: 1

Explanation:

Cisco ACI represents configuration and operational state through a hierarchical Management Information Tree, often called the MIT. Every configurable or observable element is represented as a managed object within this hierarchy. Tenants, VRFs, Bridge Domains, Application Profiles, Endpoint Groups, contracts, interface policies, and many other objects exist in this tree. Each managed object belongs to a class and has a Distinguished Name that reflects its location in the hierarchy. Understanding the MIT is important for API automation because REST requests, SDK operations, and object queries all interact with this underlying model.

Question 242.

Which identifier describes only the local name of an ACI managed object relative to its parent?

1. DN
   2. RN
   3. UUID only
   4. VLAN ID

Correct Answer: 2

Explanation:

A Relative Name, or RN, identifies a managed object relative to its parent within the ACI object hierarchy. A Distinguished Name, or DN, represents the full path from the root of the Management Information Tree to the object. The DN is effectively built from a sequence of RNs. This distinction matters in automation because scripts may need to construct or parse object paths when creating child objects or navigating parent-child relationships. UUIDs and VLAN IDs serve different purposes and do not represent the object’s hierarchical naming relationship.

Question 243.

Which APIC API response element commonly contains the returned managed objects?

1. imdata
   2. payloadOnly
   3. routeTable
   4. cliOutput

Correct Answer: 1

Explanation:

Cisco APIC API responses commonly return managed-object data inside the imdata array. Each entry contains an object class and its attributes, and may also include child objects depending on the query. Automation scripts often parse the imdata array to find specific tenants, EPGs, interfaces, or other resources. Understanding the standard response structure makes it easier to validate results and handle cases where no objects are returned. The other terms listed are not the standard top-level structure used in typical APIC REST responses.

Question 244.

Which value in a Cisco APIC API response commonly indicates the number of objects returned by a query?

1. statusCode
   2. objectCountOnly
   3. dataLength
   4. totalCount

Correct Answer: 4

Explanation:

APIC API responses commonly include totalCount, which indicates how many objects match or are returned by a query. Automation scripts can use this value to determine whether expected objects exist or to validate the scope of a class query. For example, a script may stop if totalCount unexpectedly indicates hundreds of objects when only one was expected. Response metadata should be validated before destructive operations because an overly broad query can create a large blast radius. The other values listed are not the standard APIC field used for this purpose.

Question 245.

Which Cisco ACI automation method is best when a developer wants to work with Python objects that directly correspond to APIC managed-object classes?

1. Cobra SDK
   2. Telnet only
   3. TFTP
   4. Syslog

Correct Answer: 1

Explanation:

The Cisco ACI Cobra SDK maps the ACI managed-object model into Python classes. Developers can create or query objects using Python abstractions instead of manually building every REST request and payload. This is particularly useful for complex workflows involving multiple parent-child objects because the SDK closely follows the ACI hierarchy. Telnet, TFTP, and Syslog are unrelated to object-oriented ACI configuration. The Cobra SDK does not eliminate the need to understand the underlying ACI model, because class relationships, DNs, and object attributes still determine how configuration is represented.

Question 246.

Which API query type is most efficient when an automation script needs information about all objects in one ACI class?

1. Repeated DN queries
   2. Class query
   3. ICMP sweep
   4. ARP table query

Correct Answer: 2

Explanation:

A class query retrieves multiple managed objects of the same ACI class in one request. This is usually more efficient than issuing separate Distinguished Name queries for every individual object. Class queries are useful for inventory, compliance, or discovery tasks, especially when combined with API filters that narrow the results. Repeated DN queries may be appropriate when only a few specific objects are known in advance, but they can become inefficient at scale. ICMP and ARP are unrelated to the APIC managed-object API.

Question 247.

A script needs to determine whether a particular ACI tenant already exists before creating it. Which automation approach best supports idempotency?

1. Create the tenant every time without checking
   2. Delete all tenants before deployment
   3. Query for the tenant first and create it only if absent
   4. Restart APIC before every run

Correct Answer: 3

Explanation:

An idempotent workflow first checks the current state and performs a change only when necessary. Querying for the tenant before creating it avoids unnecessary operations and prevents duplicate or conflicting actions. This is a core principle in infrastructure automation because workflows may be rerun after partial failure or as part of regular compliance processes. Deleting all tenants would be destructive, while restarting APIC has no relationship to resource existence. State-aware automation is safer and more predictable than blindly issuing create operations.

Question 248.

Which Cisco UCS construct allows a server identity to be moved from one compatible physical server to another with minimal reconfiguration?

1. BIOS setup only
   2. VLAN Pool
   3. ACI Application Profile
   4. Service Profile

Correct Answer: 4

Explanation:

A Cisco UCS Service Profile separates server identity and configuration from the underlying physical hardware. It can define UUID, MAC addresses, network connectivity, storage settings, boot order, firmware policy, and other operational parameters. Because the logical profile is separate from the physical server, it can be associated with another compatible server when hardware is replaced. This simplifies recovery and provisioning. VLAN Pools and Application Profiles belong to networking constructs, while BIOS setup alone does not provide the same abstraction and portability.

Question 249.

Which Cisco UCS concept is best for standardizing the creation of many similar Service Profiles?

1. Service Profile template
   2. ARP table
   3. Port channel
   4. Syslog facility

Correct Answer: 1

Explanation:

A Service Profile template provides a reusable standard for creating multiple Service Profiles with common settings and policy references. This reduces manual configuration and improves consistency across server deployments. Templates are especially valuable for automation because scripts can create or instantiate many profiles from one approved definition. Depending on the UCS configuration model, derived profiles may remain associated with the template or be independently instantiated. ARP tables, port channels, and Syslog facilities do not provide server-profile templating.

Question 250.

Which Cisco UCS management interface traditionally exposes an XML-based managed-object API?

1. Cisco APIC
   2. Cisco UCS Manager
   3. Cisco ISE
   4. Cisco DNA Center only

Correct Answer: 2

Explanation:

Cisco UCS Manager traditionally exposes an XML-based API built around a hierarchical managed-object model. Automation can query and modify UCS configuration by interacting with objects such as Service Profiles, policies, server inventory, and network definitions. Cisco UCS Python SDK and PowerTool can provide higher-level abstractions over the underlying API. APIC manages ACI, while ISE focuses on identity and network access control. Understanding the UCS Manager API is useful when building server automation workflows that require direct interaction with the UCS domain.

Question 251.

Which Cisco tool is most appropriate for administrators who want to automate UCS Manager operations using PowerShell?

1. Cisco UCS PowerTool
   2. Cobra SDK
   3. EEM
   4. NETCONF only

Correct Answer: 1

Explanation:

Cisco UCS PowerTool provides PowerShell cmdlets for managing UCS infrastructure programmatically. It can connect to UCS Manager, query inventory, configure policies, create Service Profiles, and automate repetitive operations. This is useful for organizations with existing PowerShell expertise. Cobra SDK is associated with Cisco ACI, EEM is an event-driven automation capability on supported Cisco devices, and NETCONF is a model-driven network management protocol. PowerTool gives administrators a familiar scripting interface over UCS managed objects.

Question 252.

Which Cisco platform provides a cloud-based API-driven management model for supported UCS infrastructure?

1. Cisco ISE
   2. Cisco Intersight
   3. Cisco CUCM
   4. Cisco Expressway

Correct Answer: 2

Explanation:

Cisco Intersight provides cloud-based infrastructure management and APIs for supported Cisco UCS and related systems. Automation can retrieve inventory, work with policies and profiles, integrate infrastructure data into workflows, and perform management operations programmatically. This differs from traditional domain-local management through UCS Manager. Cisco ISE focuses on identity and access control, while CUCM and Expressway serve collaboration functions. Intersight’s REST APIs make it especially useful for centralized, modern automation across multiple infrastructure domains.

Question 253.

Which Cisco Intersight API capability is most useful when an automation workflow must retrieve only servers with a specific model number?

1. Filtering
   2. NAT
   3. Packet fragmentation
   4. Route redistribution

Correct Answer: 1

Explanation:

Filtering allows an Intersight API request to narrow results according to specified object attributes, such as model number, organization, status, or name. This reduces the amount of data transmitted and the amount the client must process. In a large environment, using filters is much more efficient than retrieving the full inventory and searching locally. NAT, fragmentation, and route redistribution are networking concepts unrelated to REST API result selection.

Question 254.

Which mechanism should an Intersight client implement if an inventory response is limited to a fixed number of records per request?

1. Session reset
   2. Pagination
   3. Route leaking
   4. Spanning Tree

Correct Answer: 2

Explanation:

Pagination allows a client to retrieve a large dataset in multiple manageable responses. If the API limits each response to a fixed number of objects, the client should continue using the API’s supported offset, limit, cursor, or continuation mechanism until all required records are retrieved. Failure to handle pagination can result in incomplete inventory data and incorrect automation decisions. Routing and Layer 2 control mechanisms are unrelated to API result retrieval.

Question 255.

Which Ansible feature is best for grouping a set of related reusable automation tasks into a maintainable structure?

1. Role
   2. Vault password only
   3. Callback output
   4. Inventory host only

Correct Answer: 1

Explanation:

An Ansible role organizes reusable tasks, templates, variables, handlers, defaults, and files into a predictable directory structure. This makes large automation projects easier to maintain and reuse. For example, a role can encapsulate all tasks required to deploy a standard Nexus interface policy or validate device state. Inventory defines targets and Vault protects sensitive data, but neither provides the same modular organization. Roles promote consistency and reduce duplicated playbook logic.

Question 256.

Which Ansible feature can trigger a restart or reload task only when another task actually changed configuration?

1. Inventory group
   2. Handler
   3. Vault
   4. Fact gathering only

Correct Answer: 2

Explanation:

Handlers are special Ansible tasks that run when notified by another task that reports a change. They are commonly used for follow-up actions such as restarting a service, reloading configuration, or performing validation only when the underlying state changed. This supports efficient and idempotent workflows. Inventory groups organize hosts, Vault protects secrets, and fact gathering collects information. Handlers reduce unnecessary operations and allow playbooks to express dependencies between configuration changes and follow-up actions cleanly.

Question 257.

Which Terraform feature enables the same infrastructure code to be reused with different input values in multiple environments?

1. Input variables
   2. State lock only
   3. Provider checksum only
   4. Plan cache only

Correct Answer: 1

Explanation:

Terraform input variables allow configuration to accept values externally instead of hardcoding environment-specific settings. The same code can therefore be used for development, testing, and production while supplying different tenant names, VLAN IDs, controller addresses, or other parameters. This reduces duplication and improves consistency. State locking and provider checksums serve different functions. Variables also make reusable modules more flexible, because callers can customize behavior without editing the module’s internal resource definitions.

Question 258.

Which Terraform mechanism is best for packaging a standard group of resources into a reusable building block?

1. Backend
   2. Module
   3. Output only
   4. State lock

Correct Answer: 2

Explanation:

A Terraform module groups related resources and logic into a reusable component. Modules can accept input variables and expose outputs, making it possible to standardize infrastructure patterns while still supporting environment-specific customization. A team might create modules for common network constructs, policy bundles, or server configurations. Backends manage state storage, outputs expose selected values, and state locking prevents concurrent state updates. Modules are a core technique for scaling infrastructure-as-code across multiple projects.

Question 259.

Which NETCONF operation is used to modify configuration in a selected datastore?

1. <edit-config>
   2. <get>
   3. <hello>
   4. <close-session>

Correct Answer: 1

Explanation:

The NETCONF <edit-config> operation modifies configuration in a target datastore such as running or candidate, depending on device support. The request contains structured configuration data based on YANG models and can include operation instructions for merge, replace, create, or delete behavior. <get> retrieves configuration and operational state, <hello> participates in session capability exchange, and <close-session> terminates the management session. Automation should verify datastore capabilities before assuming a particular configuration workflow is supported.

Question 260.

A team wants to prevent a production infrastructure deployment unless automated tests, policy checks, plan reviews, and required approvals all succeed. Which workflow best supports this goal?

1. Run scripts directly from individual workstations
   2. Store production credentials in plaintext
   3. CI/CD pipeline with staged quality gates and approvals
   4. Disable logging during deployment

Correct Answer: 3

Explanation:

A CI/CD pipeline can enforce a structured promotion process before infrastructure changes reach production. Automated stages can run linting, syntax validation, unit tests, integration tests, Terraform planning, security checks, and policy validation. High-impact deployments can then require peer review or explicit approval. If any required check fails, the pipeline should stop automatically. Direct execution from personal workstations and plaintext credentials weaken operational controls, while disabling logging reduces auditability. Staged CI/CD provides a repeatable and safer approach to infrastructure automation.
