Cisco 300-320 Online Questions & Answers

• Question 371:

  A network consultant must propose a scalable access-distribution model where an alternative to STP technology is used to prevent Layer 2 loops. The proposed model must include these features:

  1.

  VLANs that span across the access switches

  2.

  eliminate the need for a FHRP protocol

  3.

  multichassis Ethernet technology to provide fast convergence in case of link failure

  Which design model does the consultant propose?

  A. multitier looped square access model
  B. virtual switch model
  C. multitier looped triangle access model
  D. routed access model
  B. virtual switch model

• Question 372:

  An engineer is designing a QoS architecture for a small organization and must meet these requirements:

  -Guarantees resources for a new traffic flow prior to sending

  -Polices traffic when the flow does not conform

  Which QoS architecture model will accomplish this?

  A. auto quality of service
  B. modular quality of service
  C. differentiated services
  D. integrated services
  D. integrated services

• Question 373:

  In what situation must spanning-tree be implemented?

  A. when fast convergence is required for link failures
  B. when redundant Layer 2 links, that are not part of a single EtherChannel or bundle, exist between distribution switches
  C. when trunks need to extend multiple VLANs across access switches
  D. when a VLAN spans access layer switches
  B. when redundant Layer 2 links, that are not part of a single EtherChannel or bundle, exist between distribution switches

• Question 374:

  A company is Multi-Homed to different service providers running BGP. Which action ensures that the company AS does not become a transit AS?

  A. Create a distribute list that filters all routes except the default route and applies to both BGP neighbour interfaces in the inbound direction
  B. Create a distribute list that filters all routes except the default route and applies to a single BGP neighbour in the outbound direction
  C. Create prefix list that matches the company prefixes and applies to both BGP neighbour definitions in the outbound direction.
  D. Create a route map that matches the provider BGP communities and networks and applies to both BGP neighbour interfaces in the outbound direction.
  C. Create prefix list that matches the company prefixes and applies to both BGP neighbour definitions in the outbound direction.

• Question 375:

  Which virtualization technology allows for HSRP protocol to be used in the active/active configuration where both HSRP Layer 3 devices can forward network traffic?

  A. OTV
  B. VSS
  C. vPC
  D. VDC
  C. vPC

• Question 376:

  A network administrator wants to provide high availability in a data center environment by making sure that there is no reconvergence of Layer 2 and Layer 3 protocols when there is a Layer 3 switch failure. Which Cisco Nexus feature fulfills this purpose?

  A. ISSU
  B. VSS
  C. vPC
  D. MEC
  C. vPC

• Question 377:

  Which option is correct when using Virtual Switching System?

  A. Both control planes forward traffic simultaneously
  B. Only the active switch forward traffic
  C. Both data planes forward traffic simultaneously
  D. Only the active switch handle the control plane
  C. Both data planes forward traffic simultaneously

• Question 378:

  What to configure in BGP so that other BGP neighbours cannot influence the path of a route?

  A. Lower MED
  B. Higher Local pref
  C. Higher weight
  D. Lower router ID
  C. Higher weight

• Question 379:

  A customer has several small to medium-sized remote branches and with these specific per-site requirements:

  1.

  WAN link redundancy

  2.

  3.

  low cost for WAN links

  4.

  no strict SLA requirements for the WAN links

  Which type of WAN edge connectivity design does an engineer propose?

  D. dual-homed Internet with a single edge router running a site-to-site VPN topology
  D. dual-homed Internet with a single edge router running a site-to-site VPN topology

• Question 380:

  Which two options correct when using VSS to combine two physical switches into one logical switch? (Choose two)

  A. Both data planes forward traffic simultaneously.
  B. Only one data plane forwards traffic, while the other data plane is on standby.
  C. Both control planes forward traffic simultaneously.
  D. Control planes are combined into one virtual control plane.
  A. Both data planes forward traffic simultaneously.
  D. Control planes are combined into one virtual control plane.
