Expected 300-540 Exam Topics, as suggested by Cisco :
  • Topic 1: Virtualized Architecture: This section of the exam measures the skills of Cloud Network Engineers and covers the foundational concepts of virtualized infrastructures used in modern service provider and cloud environments. Candidates are expected to understand constraints in IaaS designs, determine appropriate cloud service models, and demonstrate awareness of container orchestration compared to traditional virtual machines. The exam also evaluates the ability to implement key virtualization functions such as NFV, VNF, NSO, and virtualized Cisco platforms. Learners must be able to deploy NFV with automation tools, manage VNF onboarding, work with NSO-driven orchestration, and use protocols like NETCONF, RESTCONF, REST APIs, and gNMI within automated cloud ecosystems. A general understanding of supporting platforms such as OpenStack also forms part of the required knowledge in this domain.
  • Topic 2: Cloud Interconnect: This section of the exam measures the skills of Service Provider Network Engineers and covers how large networks interconnect with cloud platforms and carrier-neutral facilities. Candidates are expected to understand various connectivity options to cloud providers, customer sites, and other neutral facilities, as well as evaluate WAN connectivity models such as direct connect, MPLS or segment routing, and IPsec VPN links. The domain also includes the ability to troubleshoot advanced data center interconnect solutions, including EVPN VXLAN, EVPN over SR/MPLS, ACI-based connectivity, and pseudowire architectures supporting cloud-to-cloud and cloud-to-edge communication.
  • Topic 3: High Availability: This section of the exam measures the skills of Cloud Infrastructure Architects and covers the design and implementation of redundancy and resiliency mechanisms in virtualized network functions and distributed cloud platforms. It includes data plane redundancy for VNFs, high availability within a single VIM control plane, and resilient compute, vNIC, and top-of-rack switching. The exam requires an understanding of multi-homing, EVLAG configurations, virtual private cloud deployment, and ECMP strategies for NFVI integrations with physical routing protocols such as BGP, OSPF, and IS-IS. Candidates must also recommend suitable high-availability models involving DNS, routing, and load balancing.
  • Topic 4: Security: This section of the exam measures the skills of Network Security Engineers and covers the implementation of infrastructure-level protection in cloud and NFVI ecosystems. It includes topics such as ACLs, uRPF, RTBH, router hardening, BGP flowspec, TACACS, and MACSEC. Candidates should understand DoS mitigation methods and apply security practices within NFVI, focusing on API protection, securing the control and management plane, and segmentation strategies in service provider cloud environments. The domain also evaluates basic knowledge of TLS, mTLS, and general cloud security solutions related to DNS protection, zero-day defenses, and malware detection.
  • Topic 5: Service Assurance and Optimization: This section of the exam measures the skills of Cloud Operations Engineers and covers assurance mechanisms used to maintain performance, stability, and visibility across NFVI environments. It includes network assurance concepts such as MANO frameworks, VNF workload monitoring, VIM control plane KPIs, and streaming telemetry with gRPC and gNMI. Candidates must understand cloud infrastructure performance monitoring tools, including SR-PM, NetFlow, IPFIX, syslog, SNMP traps, RMON, cloud agents, and automated fault management systems. The domain also touches on diagnosing NFVI-related errors and optimizing VNFs using techniques such as SR-IOV and software-accelerated virtual switching technologies like DPDK and VPP.

Free Cisco 300-540 Exam Actual Questions

Note: Premium Questions for 300-540 were last updated On Aug. 29, 2026 (see below)

Question #1

An engineer must design a cloud platform for event-driven applications. The solution must allow micro-sized atomic components to be built, deployed, and run code on demand. Which solution must be used?

Reveal Solution Hide Solution
Correct Answer: B

Comprehensive and Detailed Explanation From Cisco Cloud Architecture Knowledge

Event-driven applications require:

Stateless, micro-sized execution units

Automatic scaling

Code that runs only when triggered

No server or VM lifecycle management

This model is known as Function-as-a-Service (FaaS).

Cisco FaaS provides:

Serverless execution

Event-driven triggers

Deployment of atomic micro-functions

Automatic scaling and resource abstraction

Ideal environment for microservices and cloud-native workloads

Why the others are incorrect:

A . Cisco+ Hybrid Cloud for VDI delivers desktops, not serverless compute

C . Cisco+ Hybrid Cloud Virtualization VM-based infrastructure, not event-driven micro-functions

D . Cisco Intersight operational management tool, not a serverless execution platform


Question #2

An engineer must design a cloud platform for managing IaC. The solution must be flexible, integrate with APIs, and allow for automation. What must be used?

Reveal Solution Hide Solution
Correct Answer: B

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


Question #3

Refer to the exhibit.

Refer to the exhibit. An engineer needs to configure ToR switches for a Cisco NFVI C-series pod. This configuration was performed on the ToR-A switch already:

feature vpc

feature lacp

interface Ethernet1/1-2

channel-group 110 mode active

interface port-channel110

Which command must be run on ToR-A to complete the port-channel configuration?

Reveal Solution Hide Solution
Correct Answer: B

In a Cisco NFVI C-Series Pod, the Top-of-Rack (ToR) switches are almost always configured as a vPC pair. A vPC domain requires three mandatory components:

vPC domain ID

vPC peer-link

vPC peer-keepalive link ensures dual-active detection

In the exhibit:

The management interfaces are Tor-A Mgmt0: 10.10.10.1 and Tor-B Mgmt0: 10.10.10.2

These IPs are used commonly as the peer-keepalive endpoints

The physical uplinks to NFVI nodes form Port-Channel110

Since the configuration snippet already includes:

feature vpc

feature lacp

channel-group 110 mode active

The next required step in a Cisco NFVI + vPC configuration is to configure the peer-keepalive from ToR-A toward ToR-B:

vpc domain 1

peer-keepalive destination 10.10.10.2

This ensures:

vPC roles sync

Dual-active prevention

Stable operation for the NFVI C-Series rack

Why the Other Options Are Incorrect

A. vpc peer-link This is required but must be configured on the dedicated peer-link interfaces, not on the server-facing port-channel.

C. channel-group 110 mode on The correct mode is already configured: mode active for LACP. mode on disables LACP.

D. switchport mode access NFVI ToR links use trunking, not access mode, because servers carry multiple networks (control, compute, storage, management VLANs).


Question #4

Refer to the exhibit.

Refer to the exhibit. An engineer is troubleshooting a physical configuration issue in Cisco NFVI. Which two observations should be made? (Choose two.)

A. The node allows two disks to fail. B. One RAID 1 disk failed. C. The node is still functional. D. The node is no longer functional. E. Two RAID 1 disks failed.

Reveal Solution Hide Solution
Correct Answer: B, C

From the RAID controller output:

The RAID1 virtual drive is shown as ''Dgrd'' (degraded) with a note: ''RAID 1 in degraded state.''

In the PD LIST, one disk (slot 2) is marked ''UGood -- active disk in slot 2 disconnected from drive group 0'', while the other (slot 3) is ''Onln 0'' (online and part of drive group 0).

This means:

In a RAID 1 mirror, only one disk may fail while the array remains available.

Here, one disk has failed/disconnected, the other is still online the array is degraded but operational.

Therefore:


Question #5

How does SR-IOV move data directly to and from the network adapter?

Reveal Solution Hide Solution
Correct Answer: C

Comprehensive and Detailed Explanation (Cisco NFVI / Virtualization Knowledge)

SR-IOV (Single Root I/O Virtualization) allows a VM to access the network interface hardware directly, without going through the hypervisor's virtual switch.

This is achieved by:

Assigning Virtual Functions (VFs) directly to VMs

Allowing high-performance, low-latency packet I/O

Bypassing the hypervisor datapath

Therefore, SR-IOV does not bypass the guest OS; it bypasses the hypervisor I/O virtualization layer, delivering near-native performance.

Thus the correct answer is C.
