Cisco 400-007 Online Questions & Answers

• Question 241:

  An engineer is designing the QoS strategy for Company XYZ. Based on initial analysis, a lot of scavenger type of traffic is traversing the network's 20Mb Internet link toward the service provider. The new design must use a QoS technique that limits scavenger traffic to 2 Mbps, which helps avoid oversubscription of the link during times of congestion. Which QoS technique can be used to facilitate this requirement?

  A. class-based traffic policing
  B. LLQ
  C. CBWFQ
  D. class-based traffic shaping
  A. class-based traffic policing

• Question 242:

  While access lists are generally associated with routers and firewalls, they can also be applied on layer 2 interfaces and to VLANs to provide granular security. Which are two benefits of using layer 2 access lists for segmentation? (Choose two.)

  A. traffic filtering
  B. contextual filtering
  C. containing lateral attacks
  D. reduced load at layer 2
  E. VLAN intercept
  A. traffic filtering
  C. containing lateral attacks

  B. DMVPN
  C. MGRE
  D. GET VPN
  D. GET VPN

• Question 245:

The team also analyzes enterprise telemetry data from IPFIX data records that are received from devices in the campus network. Which action can be taken based on the augmented data?

  A. reduction in time to detect and respond to threats
  B. integration with an incident response plan
  C. adoption and improvement of threat-detection response
  D. asset identification and grouping decisions
  A. reduction in time to detect and respond to threats

• Question 246:

  An Agile for Infrastructure transition often means dismantling traditional IT hierarchies and rebuilding it to align with business objectives and workflows.
