Cisco 300-320 Online Questions & Answers

• Question 421:

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

  A. Never use passive interfaces.
  B. Use NSSA areas from the core down.
  C. Use totally stub areas to stop type 3 LSAs.
  D. Use the lowest Ethernet interface IP address as the router ID.

• Question 422:

  Support of vPC on the Cisco Nexus 5000 access switch enables various new design options for the data center Access layer, including which of the following?

  A. The vPC peer link is not required for Access layer control traffic, and can instead be used to span VLANs across the vPC access switches
  B. A single switch can associate per-interface with more than one vPC domain
  C. vPC can be used on both sides of the MEC, allowing a unique 16-link EtherChannel to be built between the access and aggregation switches
  D. Allows an EtherChannel between a server and a access switch while still maintaining the level of availability that is associated with dual-homing a server to two different access switches
  C. vPC can be used on both sides of the MEC, allowing a unique 16-link EtherChannel to be built between the access and aggregation switches

• Question 423:

  An engineer have to design a multicast domain for some application. This multicast network should be secured. Which option should he take ?

  A. ASM with an addressing of 224.0.0.0/8
  B. ASM with an addressing of 232.0.0.0/8
  C. SSM with an addressing of 224.0.0.0/8
  D. SSM with an addressing of 232.0.0.0/8
  D. SSM with an addressing of 232.0.0.0/8

• Question 424:

  A data center has several business partners who want to have their compute resources installed. The data center uses one VLAN to support vendor equipment and requires limited visibility and connectivity between vendor servers. Which segmentation concept satisfies theses requirements?

  A. Ip NAT
  B. Private vlans
  C. LAN-toLAN VPN
  D. Protected VLANs
  B. Private vlans

• Question 425:

  Which technology guarantees loop free network and does not contain the state "listening"?

  A. RPVST+
  B. STP
  C. VSS
  D. MEC
  A. RPVST+

• Question 426:

  Which option is a primary requirement for the deployment of an IPv6-enabled network via the native method (dual-stack model) within the enterprise campus environment?

  A. hardware-based switching support for IPv6 forwarding on all campus switches
  B. restriction of IPv6-enabled devices to the core layer
  C. manual implementation of tunneling between IPv6-incompatible devices in an IPv4-over-IPv6 tunnel
  D. disabling of multicast in the distribution layer prior to implementation of IPv6
  A. hardware-based switching support for IPv6 forwarding on all campus switches

• Question 427:

  Which two of these are correct regarding the recommended practice for distribution layer design? (Choose two.)

  A. use a redundant link to the core
  B. use a Layer 2 link between distribution switches
  C. never use a redundant link to the core because of convergence issues
  D. use a Layer 3 link between distribution switches with route summarization
  E. use a Layer 3 link between distribution switches without route summarization
  A. use a redundant link to the core
  E. use a Layer 3 link between distribution switches without route summarization

  ---

  We need to summarize from distribution to core but not between distribution switches.

• Question 428:

  An engineer is considering time of convergence in a new layer 3 environment design. Which two attributes must be considered? (Choose two.)

  A. OSPF database updates
  B. SPT timers updates
  C. Addition of a valid forwarding path
  D. Forwarding table updates
  E. Loss of a valid forwarding path
  D. Forwarding table updates
  E. Loss of a valid forwarding path

• Question 429:

  Which two statements about both FCIP and iSCSI are correct? (Choose two.)

  A. They support file-level storage for remote devices.
  B. They require high throughput with low latency and low jitter.
  C. Their purpose is to provide connectivity between host and storage.
  D. They support block-level storage for remote devices.
  E. Their purpose is to provide connectivity between separate wide-area SANs.
  D. They support block-level storage for remote devices.
  E. Their purpose is to provide connectivity between separate wide-area SANs.

• Question 430:

  An outsourced call center is using SIP VoIP telephony that imposes restrictions on the use of NAT. the company expects the number of call center staff to grow from 100 to 200 people. Which two design solutions ensure the most cost efficient and scalable way for call center staff to access internal corporate applications? (Choose two.)

  A. Request that the call center use public IP addresses for agent workstations.
  B. Provide the call center with a /24 private IP subnet that is unique on both sides.
  C. Configure a single IP address to create dynamic port translations for agent workstations.
  D. Utilize NAT pool to translate IP addresses provided by the call center.
  E. Implement 1-to-1 NAT translation for each of the agent workstations.
  A. Request that the call center use public IP addresses for agent workstations.
  D. Utilize NAT pool to translate IP addresses provided by the call center.
