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 protocol is used in an in-band network and why?

  A. UDP, because it is connectionless
  B. SSH, because the username and password are encrypted
  C. Telnet, because the username and password are sent in clear
  D. MSDP, because it uses TCP as its transport protocol
  B. SSH, because the username and password are encrypted

• Question 13:

  An engineer is designing an address plan. Which IPv6 prefix removes any consideration regarding the number of hosts per subnet?

  A. /32
  B. /48
  C. /64
  D. /96
  C. /64

• Question 14:

  Which network virtualization plane is used to separate traffic forwarding tables?

  A. control
  B. data
  C. management
  D. access
  B. data

• Question 15:

  A company is running BGP on the edge with multiple service providers in a primary and secondary role. The company wants to speed up time if a failure were to occur with the primary, but they are concerned about router resources. Which method best achieves this goal?

  A. Utilize BFD and lower BGP hello interval
  B. Decrease the BGP keepalive timer
  C. Utilize BFD and tune the multiplier to 50
  D. Utilize BFD and keep the default BGP timers
  D. Utilize BFD and keep the default BGP timers

• Question 16:

  What network storage protocol uses a connection standard incompatible with shared 10Gb Ethernet physical connection?

  A. SMB
  B. iSCSI
  C. FC
  D. NFS
  E. CIFS
  C. FC

• Question 17:

  An engineer is working for a large scale cable TV provider that requires multicast on multisourced streaming video, but must not use any rendezvous point mechanism. Which multicast protocol must be configured?

  A. SSM
  B. ASM
  C. PIM-SM
  D. BIDIR-PIM
  A. SSM

• Question 18:

  A network Engineer is designing a hierarchical design and needs to optimize WAN design. On what group of devices can a network engineer summarise routes to remote WAN sites?

  A. Core
  B. Distribution
  C. Data Center Distribution WAN Edge
  D. WAN Edge
  E. Campus access distribution layer
  B. Distribution

  ---

  Summarize at Service Distribution. It is important to force summarization at the distribution towards WAN Edge and towards campus and data centre

• Question 19:

  Addressing QoS design in the Enterprise Campus network for IP Telephony applications means what?

  A. It is critical to identify aggregation and rate transition points in the network, where preferred traffic and congestion QoS policies should be enforced
  B. Suspect traffic should be dropped closest to the source, to minimize wasting network resources
  C. An Edge traffic classification scheme should be mapped to the downstream queue configuration
  D. Applications and Traffic flows should be classified, marked and policed within the Enterprise Edge of the Enterprise Campus network
  A. It is critical to identify aggregation and rate transition points in the network, where preferred traffic and congestion QoS policies should be enforced

• Question 20:

  Multicast has been configured and enabled within an Enterprise network. PIM spare-mode has been enabled on all VLANs. What feature is required to stop multicast traffic from being broadcasted on the access layer switches?

  A. Multicast boundary filter
  B. PIM Dense-Mode
  C. IGMP snooping
  D. Dynamic ARP inspection
  C. IGMP snooping
