Cisco 300-540 Exam Syllabus Topics:

TopicDetails
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
  • 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.
Topic 3
  • 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 4
  • 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 5
  • 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.

Cisco Designing and Implementing Cisco Service Provider Cloud Network Infrastructure Sample Questions (Q68-Q73):

NEW QUESTION # 68

Refer to the exhibit. An engineer is troubleshooting a Cisco NFVI issue where the management node fails to start. Which service must be restarted to resolve the issue?

Answer: C

Explanation:
In Cisco NFVI, themanagement noderelies heavily on Docker containers for:
* NFVIS management functions
* VIM services
* Orchestration components
If the management node fails to start and the system shows:
docker.service: inactive (dead)
...then all Docker-based platform services also fail to start.
The correct recovery action is torestart the Docker engine:
systemctl restart docker
This brings up:
* All NFVI-required Docker containers
* Management services
* REST APIs and cluster components
Why other answers are incorrect:
* docker-kibana# Only affects Kibana logging container
* docker-cobbler# Used for provisioning, not core NFVI management
* kube-apiserver# Part of Kubernetes cluster, but relies on Docker; restarting it won't help until Docker is running Thus, the correct answer isB. docker.


NEW QUESTION # 69
EVPN over SR/MPLS can solve which of the following issues?

Answer: B,D


NEW QUESTION # 70
Troubleshooting ACI involves understanding:

Answer: C


NEW QUESTION # 71
An engineer must implement a SaaS solution that will use a Cisco ASAv to enhance security for enterprise customers by using Cisco Crosswork NSO. Which command must be run in NSO?

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Cisco NSO Orchestration Knowledge In Cisco NSO deployments:
* ncs-setupis only used once, during initial NSO instance creation.
* ls -l nso-instance/packages/simply lists packages - not used to start NSO.
* ncs -statuschecks status but doesnotrun NSO.
To actuallystart the NSO serviceso that device packages (including ASAv service packages) can be loaded and orchestration can begin, the correct command is:
ncs
This launches the NSO runtime and loads all configured packages, enabling the SaaS ASAv service.


NEW QUESTION # 72
What is a valid connection method between carrier-neutral facilities within the same metro area?

Answer: B

Explanation:
Comprehensive and Detailed Explanation Based on Designing and Implementing Cisco Service Provider Cloud Network Infrastructure Knowledge When connectingcarrier-neutral facilities (CNFs)ordata centerswithin the same metropolitan area, service providers typically usehigh-bandwidth, low-latency optical transport methods. The most appropriate and commonly deployed interconnection technology is:
DWDM (Dense Wavelength Division Multiplexing) ring, which provides:
* High capacity (10G, 40G, 100G, 400G)
* Low latency
* Redundancy through ring or mesh topologies
* Multi-wavelength multiplexing for cost efficiency
* Carrier-grade reliability for metro interconnect services
This aligns with cloud interconnect and metro transport design used in service provider environments.
Evaluation of the Options
A). OSPF backbone area adjacency
This is a routing protocol adjacency, not a physical connection method. It requires a transport link underneath but does not represent the physical interconnect itself.
B). Private wireless connection
Not suitable for CNF or metro DC interconnect because it lacks the bandwidth, reliability, and deterministic performance required for large-scale carrier-grade interconnects.
C). DWDM ring
This is the correct method. DWDM-based metro fiber rings are the standard for connecting carrier-neutral facilities in the same metro region.
D). CAT6e connection
This is limited to short-distance copper Ethernet (tens of meters). It is not used for metro-scale interconnects or between CNFs.
