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
  • 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 3
  • 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 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
  • 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.

Cisco Designing and Implementing Cisco Service Provider Cloud Network Infrastructure Sample Questions (Q149-Q154):

NEW QUESTION # 149
An engineer must implement a solution on a Cisco ASR 1000 Series router to protect against DDoS attacks.
DDoS traffic must be dropped by transmitting Flowspec attributes to edge routers, instructing them to generate an ACL via class-maps and policy-maps. The engineer already configured BGP neighbors. Which action must be taken next?

Answer: A

Explanation:
Comprehensive and Detailed Explanation
BGP Flowspec allows routers to distributetraffic-filtering rulesusing BGP NLRI.
To enable Flowspec, after neighbors are configured, the essential next step is:
#Activate the Flowspec address-family under BGP
Example:
router bgp 65000
address-family ipv4 flowspec
neighbor X.X.X.X activate
exit-address-family
This enables:
* FlowSpec NLRI exchange
* Distribution of drop rules (rate-limit, redirect, null route, etc.)
* Automatic ACL/class-map/policy-map generation on edge routers
Why the other options are incorrect:
* B. Set BGP routing process# already done when neighbors were configured
* C. Activate neighbors# only makes senseinsidean address-family; flowspec AF must be enabled first
* D. Configure route reflector# optional and not required for Flowspec to operate Thus, the correct next step isA. Configure Flowspec for the BGP address-family.


NEW QUESTION # 150
What are the key advantages of using cloud agents for network monitoring? (Select two)

Answer: B,D


NEW QUESTION # 151

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

Answer: D,E

Explanation:
From the RAID controller output:
* TheRAID1virtual drive is shown as"Dgrd" (degraded)with a note:"RAID 1 in degraded state."
* In thePD 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 aRAID 1mirror, onlyone diskmay fail while the array remains available.
* Here,one disk has failed/disconnected, the other is still online # the array isdegraded but operational.
Therefore:
* B. One RAID 1 disk failed- correct.
* C. The node is still functional- correct; RAID1 can tolerate a single disk failure.
The other options are incorrect:
* A and Esuggest two disk failures, which is not indicated.
* Dwould be true only if both disks failed; with one disk still online, the node continues to function, though in a degraded state.


NEW QUESTION # 152
An engineer attempts to kill a NETCONF session. The session ID is equal to the current session. What is the effect of this action?

Answer: B

Explanation:
NETCONF rules state:
* A user cannot terminatetheir own active session.
* Attempting to kill the same session returnsinvalid-valueerror.
* The session continues running normally.
Thus:
* No logout
* No termination
* No configuration impact
Therefore,Ais correct.


NEW QUESTION # 153
VIM control plane KPIs are important for:

Answer: D
