Cisco 300-320 Online Practice Questions and Exam Preparation

Cisco 300-320 Online Questions & Answers

• Question 11:

  Which of these statements best describes VPLS?

  A. Neither broadcast nor multicast traffic is ever flooded in VPLS.
  B. Multicast traffic is flooded but broadcast traffic is not flooded in VPLS.
  C. VPLS emulates an Ethernet switch, with each EMS being analogous to a VLAN.
  D. Because U-PE devices act as IEEE 802.1 devices, the VPLS core must use STP.
  E. When the provider experiences an outage, IP re-routing restores PW connectivity and MAC re-learning is needed.
  C. VPLS emulates an Ethernet switch, with each EMS being analogous to a VLAN.

• Question 12:

  Which path selection protocol is used by Fibre Channel fabrics?

  A. IVR
  B. VoQ
  C. FSPF
  D. VSANs
  E. SANTap
  C. FSPF

• Question 13:

  At a certain customer's site, a NAS is both physically and logically in the traffic path. The NAS identifies clients solely based on their MAC addresses. In which access mode has this NAS been configured to operate?

  A. Layer 2 mode
  B. Layer 3 Edge mode
  C. Layer 3 Central mode
  D. Layer 3 In-Band mode
  A. Layer 2 mode

• Question 14:

  Which of these is true of IP addressing with regard to VPN termination?

  A. addressing designs need to allow for summarization
  B. termination devices need routable addresses inside the VPN
  C. IGP routing protocols will update their routing tables over an IPsec VPN
  D. designs should not include overlapping address spaces between sites, since NAT is not supported
  C. IGP routing protocols will update their routing tables over an IPsec VPN

  ---

  explanation:

  An IPsec VPN is an overlay on an existing IP Network. The VPN termination devices need routable IP addresses for the outside Internet connection. Private IP address can be used on the inside of the VPN. Just a good IP network design supports summarization, the VPN address space needs to be designed to allow for network summarization. NAT may be needed to support overlapping address space between sites in an organization.

• Question 15:

  Which of these is least important when determining how many users a NAS can support?

  A. bandwidth
  B. number of plug-ins per scan
  C. total number of network devices
  D. number of checks in each posture assessment
  A. bandwidth

• Question 16:

  Which two characteristics are most typical of a SAN? (Choose two.)

  A. NICs are used for network connectivity.
  B. Servers request specific blocks of data.
  C. Storage devices are directly connected to servers.
  D. A fabric is used as the hardware for connecting servers to storage devices.
  E. The TCO is higher because of the cost of director class storage switches.
  B. Servers request specific blocks of data.
  D. A fabric is used as the hardware for connecting servers to storage devices.

• Question 17:

  Which two statements about Layer 3 access designs are correct? (Choose two.)

  A. IP address space is difficult to manage.
  B. Broadcast and fault domains are increased.
  C. Convergence time is fractionally slower than STP.
  D. Limits on clustering and NIC teaming are removed.
  E. Fast uplink convergence is supported for failover and fallback.
  A. IP address space is difficult to manage.
  E. Fast uplink convergence is supported for failover and fallback.

• Question 18:

  Which of these practices should you follow when designing a Layer 3 routing protocol?

  A. Never peer on transit links.
  B. Build squares for deterministic convergence.
  C. Build inverted U designs for deterministic convergence.
  D. Summarize routes at the distribution to the core to limit EIGRP queries or OSPF LSA propagation.
  D. Summarize routes at the distribution to the core to limit EIGRP queries or OSPF LSA propagation.

• Question 19:

  What is the recommended radius of a cell for a voice-ready wireless network?

  A. 6 dBm
  B. 7 dBm
  C. 19 dBm
  D. 5 dBm
  E. -67 dBm
  F. -86 dBm
  E. -67 dBm

• Question 20:

  In a base e-Commerce module design, which routing statement is correct?

  A. Routing is mostly static.
  B. Hardcoded IP addresses are used to support failover.
  C. Inbound servers use the CSM or ACE as the default gateway.
  D. VLANs between the access layer switches are used for FHRP protocols.
  A. Routing is mostly static.
