Cisco 300-320 Online Questions & Answers

• Question 1:

  What is the primary benefit of implementing Virtual Device Contexts on Nexus hardware In a multi- tenant environment?

  A. resource isolation
  B. software partitioning
  C. resource allocation
  D. granular monitoring
  A. resource isolation

• Question 2:

  When adding an IPSec headend termination device to your network design, which two performance indicators are the most accurate to determine device scalability? (Choose two.)

  A. CPU capabilities
  B. bandwidth capabilities
  C. packets per second capabilities
  D. maximum tunnel termination capabilities
  C. packets per second capabilities
  D. maximum tunnel termination capabilities

• Question 3:

  An engineer is designing an infrastructure to use a 40 Gigabit link as the primary uplink and a 10 Gigabit uplink as the alternate path. Which Routing protocol allows for unequal cost load balancing?

  A. Ospf
  B. Eigrp
  C. ISIS
  D. BGP
  E. RIP
  B. Eigrp

  ---

  Traffic Sharing EIGRP not only provides unequal cost path load balancing, but also intelligent load balancing, such as traffic sharing. In order to control how traffic is distributed among routes when there are multiple routes for the same destination network that have different costs, use the traffic-share balanced command. With the keyword balanced , the router distributes traffic proportionately to the ratios of the metrics that are associated with different routes.

• Question 4:

  What is advantage of using the vPC feature in Data Centre environment?

  A. Two switches form a single control plane
  B. Utilizes all available uplinks bandwidth
  C. FHRP is not required
  D. A single IP is used for management for both devices
  B. Utilizes all available uplinks bandwidth

• Question 5:

  EIGRP configured on access switch level. What needs to be taken into account for optimal results?

  A. Configure stub networks
  B. configuring switch-to-switch
  C. carry multiple VLANs
  D. fixed-configuration switches
  A. Configure stub networks

• Question 6:

  Which two design recommendations are most appropriate when EIGRP is the data center core routing protocol? (Choose two.)

  A. Summarize data center subnets.
  B. Use passive interfaces to ensure appropriate adjacencies.
  C. Tune the EIGRP timers to enable EIGRP to achieve quicker convergence.
  D. Adjust the default bandwidth value to ensure proper bandwidth on all links.
  E. Advertise a default summary route into the data center core from the aggregation layer.
  A. Summarize data center subnets.
  B. Use passive interfaces to ensure appropriate adjacencies.

  ---

  "Here are some recommendations on EIGRP design for the data center core layer:

  Advertise a default summary route into the data center access layer with the ip summary- address eigrp interface command on the aggregation layer. If other default routes exist in the network, such as from the Internet edge, you might need

  to filter them using distribute lists. Summarize the data center access layer subnets with the ip summary-address eigrp interface command from the aggregation layer. Use the passive-interface default command, and advertise only on the

  links that need to participate in the routing process using the no passive-interface interface command."

• Question 7:

  While configuring a QoS policy, analysis of the switching infrastructure indicates that the switches support 1P3Q3T egress queuing. Which option describes the egress queuing in the infrastructure?

  A. The threshold configuration allows for inter-queue QoS by utilizing buffers.
  B. The priority queue must contain real-time traffic and network management traffic.
  C. The 1P3Q3T indicates one priority queue, three standard queues, and three thresholds.
  D. The priority queue should use less than 20% of the total bandwidth.
  C. The 1P3Q3T indicates one priority queue, three standard queues, and three thresholds.

• Question 8:

  In which OSI layer does IS-IS operate?

  A. Layer 1
  B. Layer 2
  C. Layer 3
  D. Layer 4
  B. Layer 2

Which BGP mechanism can be deployed to protect the session from this type of attack?

  A. BGP communities
  B. BGP outbound route filters
  C. BGP AS path length limiting
  D. BGP TTL security check
  D. BGP TTL security check

  A. OSPF
  B. RIP
  C. EIGRP
  D. BGP
  E. IS-IS
  C. EIGRP
