• Question 621:

  Which statement about using native VLANs to carry untagged frames is true?

  A. Cisco Discovery Protocol version 2 carries native VLAN information, but version 1 does not.
  B. Cisco Discovery Protocol version 1 carries native VLAN information, but version 2 does not.
  C. Cisco Discovery Protocol version 1 and version 2 carry native VLAN information.
  D. Cisco Discovery Protocol version 3 carries native VLAN information, but versions 1 and 2 do not.
  A. Cisco Discovery Protocol version 2 carries native VLAN information, but version 1 does not.

  B. They support static source MAC address
  C. They require PortFast to be enabled manually on the interface
  D. When they are enabled, all CoS values in incoming traffic are untrusted

• Question 630:

  Which statement about the use of SDM templates in a Cisco switch is true?

  A. SDM templates are used to configure system resources in the switch to optimize support for specific features, depending on how the switch is used in the network.
  B. SDM templates are used to create Layer 3 interfaces (switch virtual interfaces) to permit hosts in one VLAN to communicate with hosts in another VLAN.
  C. SDM templates are used to configure ACLs that protect networks and specific hosts from unnecessary or unwanted traffic.
  D. SDM templates are used to configure a set of ACLs that allows the users to manage the flow of traffic handled by the route processor.
  E. SDM templates are configured by accessing the switch using the web interface.
  A. SDM templates are used to configure system resources in the switch to optimize support for specific features, depending on how the switch is used in the network.

  ---

  Explanation: You can use SDM templates to configure system resources in the switch to optimize support for specific features, depending on how the switch is used in the network. You can select a template to provide maximum system usage for some functions; for example, use the default template to balance resources, and use access template to obtain maximum ACL usage. To allocate hardware resources for different usages, the switch SDM templates prioritize system resources to optimize support for certain features.
