Cisco 300-540 Prüfungsplan:

ThemaEinzelheiten
Thema 1
  • 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.
Thema 2
  • 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.
Thema 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.
Thema 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.
Thema 5
  • 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.

Cisco Designing and Implementing Cisco Service Provider Cloud Network Infrastructure 300-540 Prüfungsfragen mit Lösungen (Q139-Q144):

139. Frage
NetFlow and IPFIX are protocols used for:

Antwort: C


140. Frage
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?

Antwort: C

Begründung:
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.


141. Frage
What role does NFVI MANO play in service assurance?

Antwort: D


142. Frage
What is an information-gathering capability of Cisco IOS Flexible NetFlow in Cisco NFVI?

Antwort: D

Begründung:
Comprehensive and Detailed Explanation From Cisco NFVI Knowledge
Cisco IOSFlexible NetFlowis the primary telemetry and flow-collection mechanism used across Cisco NFVI platforms. One of its powerful information-gathering capabilities is the ability to createmultiple, separate flow caches, each one with:
* Its own key fields
* Its own record type
* Its own export destination
This allows NFVI deployments to capturedifferent types of traffic visibility(control plane, data plane, management, or tenant-specific flows) withindependent caches, which improves scalability and granularity.
Why the other options are incorrect:
* DockerandKubernetes(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.


143. Frage
What is a capability of a Cisco NFVIS SNMP trap?

Antwort: C

Begründung:
Comprehensive and Detailed Explanation
SNMP traps in Cisco NFVIS (and in SNMP generally):
* Areunsolicited notifications
* Sent from the NFVIS deviceto the SNMP manager
* Indicate alarms, changes, or significant operational events
* Donotrequire polling
Examples:
* Disk failures
* VM crashes
* Host status changes
* Resource alarms
Why the others are wrong:
* Adescribes SNMP monitoring (done by the manager with GET requests)
* BSNMP cannotcontrolhost activities
* DSNMP GET retrieves a variable, but traps sendunsolicitednotifications Thus, the correct answer isC.
