Cisco 300-320 Online Questions & Answers

• Question 51:

  In which multicast configuration is MSDP most useful?

  A. Interdomain IPv4 PIM sparse-Mode
  B. Interdomain IPv4 PIM dense-Mode
  C. Intra-domain IPv4 PIM dense-Mode
  D. Intra-domain IPv4 PIM sparse-Mode
  A. Interdomain IPv4 PIM sparse-Mode

  ---

  "Multicast Source Discovery Protocol (MSDP) is a Protocol Independent Multicast (PIM) family multicast routing protocol defined by Experimental RFC 3618.

  MSDP interconnects multiple IPv4 PIM Sparse-Mode

  (PIM-SM) domains which enables PIM-SM to have Rendezvous Point (RP) redundancy and inter-domain multicasting RFC 4611"

• Question 52:

  A. to a core switch running Cisco NSF and SSO from redundant distribution switches connected with a Layer 2 link
  B. to a core switch running Cisco NSF and SSO from redundant distribution switches connected with a Layer 3 link
  C. to two core switches from redundant distribution switches connected with a Layer 2 link
  D. to two core switches from redundant distribution switches connected with a Layer 3 link
  E. to two core switches running Cisco NSF and SSO from two redundant distribution switches running Cisco NSF and SSO
  D. to two core switches from redundant distribution switches connected with a Layer 3 link

• Question 53:

  A. It is assigned by the Cisco ISE to the user or endpoint session upon login
  B. Best practice dictates it should be statically created on the switch
  C. It is removed by the Cisco ISE before reaching the endpoint.
  D. Best Practice dictates that deployments should include a guest group allowing access to minimal services

• Question 54:

  About interconnecting with new company , both companies uses OSPF and the questions is about how should you filter the ingress traffic between them

  A. Use eigrp on the other company
  B. Use distribute-list
  C. Use prefix-list
  D. Use ACL
  B. Use distribute-list

• Question 55:

  With respect to address summarization, which of the following statements concerning IPv4 and IPv6 is true?

  A. The potential size of the IPv6 address blocks suggests that address summarization favors IPv6 over IPv4.
  B. Role based addressing using wildcard masks to match multiple subnets is suitable for IPv4, but unsuitable for IPv6.
  C. In order to summarize, the number of subnets in the IPv4 address block should be a power of 2 while the number of subnets in the IPv6 address block should be a power of 64.
  D. WAN link addressing best supports summarization with a /126 subnet for IPv4 and a /31 for IPv6.
  B. Role based addressing using wildcard masks to match multiple subnets is suitable for IPv4, but unsuitable for IPv6.

  http://www.ciscopress.com/articles/article.asp?p=1763921 For IPv6 access lists, the wildcard masks are not usually used. All source and destination addresses are notated in the form of prefixes. Therefore, it is important that subnets that are to be grouped in an access list falling within a summarized address range.

  D. IEEE 802.1S
  C. IEEE 802.1Q
