Cisco 300-540 Exam Dumps

Comprehensive and Detailed Explanation

Infrastructure as Code (IaC) requires:

Declarative configuration

Automation

API-driven workflows

Multi-cloud capability

Integration with orchestration and provisioning tools

Terraform is a widely adopted IaC platform supporting:

Cloud automation (AWS, Azure, GCP, private clouds)

Cisco infrastructure provisioning (Nexus, ACI, IOS-XR, NSO, SD-WAN, etc.)

REST APIs and providers for programmability

Cisco provides official Terraform providers for multiple platforms, enabling full IaC operations. This aligns exactly with SP cloud automation design principles.

Other options:

Cloud-based sandboxes For testing, not IaC automation

ThousandEyes Monitoring and performance analytics

AppDynamics Application performance management

Comprehensive and Detailed Explanation From Cisco NFVI Knowledge

Cisco IOS Flexible NetFlow is the primary telemetry and flow-collection mechanism used across Cisco NFVI platforms. One of its powerful information-gathering capabilities is the ability to create multiple, separate flow caches, each one with:

Its own key fields

Its own record type

Its own export destination

This allows NFVI deployments to capture different types of traffic visibility (control plane, data plane, management, or tenant-specific flows) with independent caches, which improves scalability and granularity.

Why the other options are incorrect:

Docker and Kubernetes (B, D) are container orchestration tools, unrelated to NetFlow flow-gathering capabilities.

Single cache (C) is traditional NetFlow, not Flexible NetFlow. Flexible NetFlow explicitly supports multiple independent caches.

In an NFV environment following Cisco NFV Infrastructure and ETSI MANO architecture, the onboarding workflow for VNF deployment follows this high-level order:

Define VNF descriptors (VNFD and NSD)

-- Includes implementation details and service definitions.

Prepare virtual machine resources

-- Flavor, image, CPU/memory/storage, and placement.

Define the NFV network

-- This step builds the underlay/overlay connectivity needed for the VNF.

-- It includes virtual network creation, interfaces, VLs (Virtual Links), connection points, and mapping into OpenStack (Neutron networks, subnets, ports).

-- No VNF can be deployed until the NFV service networks (management, control, data, HA) are defined.

Apply Day-0 configuration

-- Bootstrapping/initial config.

Apply Day-1 operational characteristics

-- Routing, services, policies.

Configure operational monitoring (KPIs)

-- Performance and fault measurements.

Since the question states ''after the VM resources are prepared'', the next mandatory stage is defining the virtual network connectivity on which the VNFs will operate.

Comprehensive and Detailed Explanation From Exact Extract from my knowledge of Designing and Implementing Cisco Service Provider Cloud Network Infrastructure Outlines without Any External URL or Links: Container orchestration is the automated management of container lifecycle tasks such as deployment, scaling, failover, and updates. In Cisco cloud and NFV design guidance, typical orchestration platforms include Docker (with Swarm) and Kubernetes, which integrate with Cisco networking and security for cloud-native workloads.

Docker provides the container runtime and can also perform basic orchestration through Docker Swarm mode, managing multi-container, multi-host deployments.

Kubernetes is a full-featured orchestration system that automates deployment, scaling, and operations of application containers across clusters. It is the de-facto standard used with Cisco Container Platform and other Cisco cloud solutions.

VMware vCenter, Cisco vManage, and Cisco vSmart focus on virtual machines or SD-WAN control, not container orchestration. Therefore, the correct tools are Docker and Kubernetes (A, D).

In Cisco Catalyst SD-WAN cloud integration, when the requirement is:

Automatically discovering AWS VPCs

Automatically identifying AWS services

Allowing the user to choose which private SD-WAN network connects to the cloud

Using AWS credentials (Access Key / Secret Key) for automatic provisioning

...the Cisco-supported mechanism is the Cisco SD-WAN Transit VPC solution.

Why Transit VPC is the correct answer:

It is specifically designed to integrate Cisco SD-WAN with AWS environments.

Uses AWS APIs and user credentials to automatically discover:

VPC IDs

Subnets

Regions

Routing tables

Automatically deploys and configures CSR1000v or Catalyst 8000V routers into the VPC.

Provides a centralized ''hub'' in AWS to interconnect multiple SD-WAN sites.

Enables the user to choose which SD-WAN segments connect to which VPCs.

This matches the requirement of automatic cloud resource identification based on user credentials.

Why the other options are incorrect

A . AWS Direct Connect

This is a physical/private Layer 2 cloud connection.

It does not auto-discover VPCs or integrate through credentials.

It does not provide automated SD-WAN service provisioning.

C . IPsec VPN

Works for connectivity but is manual, not automated.

Does not identify AWS cloud resources via credentials.

D . Segment routing

A transport technology used inside SP networks, irrelevant to AWS API-based VPC discovery.

Thus, only Transit VPC provides automatic AWS cloud discovery and integration with SD-WAN.
