Cisco 300-540 Exam Syllabus Topics:

Topic	Details
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	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	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 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 (Q29-Q34):

NEW QUESTION # 29
The primary goal of implementing a virtual private cloud (VPC) is to:

A. Provide isolated network environments within a public cloud
B. Reduce overall cloud costs
C. Simplify network management
D. Decrease network security

Answer: A

NEW QUESTION # 30
What is used to protect against an API logic flaw?

A. Data encryption at rest
B. Remediation of vulnerabilities
C. SSH encryption at rest
D. Data encryption in transit

Answer: B

Explanation:
Comprehensive and Detailed Explanation
AnAPI logic flawis a weakness in the API'sbusiness logic- not in encryption or transport security. It occurs when:
* API functions are misused
* Business rules are bypassed
* Security validation is missing
* Workflow logic is incorrect
These issues cannot be solved through encryption (at rest or in transit). They require:
#Vulnerability remediation
#Fixing API code logic
#Updating API validation, flow control, and authentication logic
Thus the correct answer isC. Remediation of vulnerabilities.

NEW QUESTION # 31

Refer to the exhibit. An engineer must configure an IPsec VPN connection between site 1 and site 2. The indicated configuration was applied to router R1; however, the tunnel fails to come up. Which command must be run on R1 to resolve the issue?

A. ip route 0.0.0.0 0.0.0.0 10.1.1.2
B. ip route 0.0.0.0 0.0.0.0 192.168.20.2
C. crypto isakmp key vpnuser address 192.168.20.2
D. crypto isakmp key vpnuser address 10.1.1.2

Answer: C

Explanation:
For a site-to-site IPsec VPN, each peer must configure apre-shared keytied to thepublic IP address of the remote VPN peer:
crypto isakmp key <KEY> address <REMOTE_PUBLIC_IP>
From the diagram:
* R1 outside IP:192.168.10.1/24
* R2 outside IP:192.168.20.2/24# remote peer for R1
In the current R1 configuration, the ISAKMP key is incorrectly bound to192.168.10.2, which is a local next- hop/ISP address on R1's own subnet, not the R2 public IP. Because the pre-shared-key address does not match the source IP of R2's IKE packets, phase 1 negotiation fails and the tunnel never comes up.
The correct configuration on R1 must therefore be:
crypto isakmp key vpnuser address 192.168.20.2
Options A and C incorrectly change the default route (next hop must be the local ISP router, not R2's public IP or a LAN address). Option D uses an internal address (10.1.1.2), which is not the IP used for IKE on the Internet.

NEW QUESTION # 32
NetFlow and IPFIX are protocols used for:

A. Physical layer diagnostics
B. Data encryption
C. Network configuration
D. Traffic analysis and monitoring

Answer: D

NEW QUESTION # 33

Refer to the exhibit. An engineer must design a solution that allows a user to choose which private Cisco Catalyst SD-WAN network they want to connect to AWS. The solution must automatically identify the AWS VPC and other cloud services based on the user credentials. What must be used?

A. Segment routing
B. AWS Direct Connect
C. IPsec VPN
D. Transit VPC for AWS

Answer: D

Explanation:
In Cisco Catalyst SD-WAN cloud integration, when the requirement is:
* Automatically discovering AWSVPCs
* Automatically identifying AWSservices
* Allowing the user to choose whichprivate SD-WAN networkconnects to the cloud
* UsingAWS credentials(Access Key / Secret Key) for automatic provisioning
...the Cisco-supported mechanism is theCisco SD-WAN Transit VPC solution.
Why Transit VPC is the correct answer:
* It is specifically designed to integrateCisco SD-WANwith 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 ofautomatic 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 doesnotauto-discover VPCs or integrate through credentials.
* It does not provide automated SD-WAN service provisioning.
C). IPsec VPN
* Works for connectivity but ismanual, 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, onlyTransit VPCprovides automatic AWS cloud discovery and integration with SD-WAN.
