  Select and Place:

  

  

• Question 202:

  Refer to the exhibit.

  

  What happens to packets when traffic in the icmp-class class exceeds the policed amount?

  A. Packets are discarded and a message is logged.
  B. Packets are discarded and a trap is sent to any servers that are configured to receive traps.
  C. Packets are discarded silently.
  D. Packets are discarded and an inform is sent to any servers that are configured to receive informs.
  C. Packets are discarded silently.

  service-policy {input| output policy-map-name

  Example:

  Router(config-cp)# service-policy input control-plane-policy

  Attaches a QoS service policy to the control plane. Note the following points:

  input --Applies the specified service policy to packets received on the control plane. output --Applies the specified service policy to packets transmitted from the control plane and enables the router to silently discard packets. policy-map-name

  -- Name of a service policy map (created using the policy- mapcommand) to be attached. The name can be a maximum of 40 alphanumeric characters.

  In this case, the service policy is set to output, which drops the traffic silently per above.

• Question 204:

  Which two options describe two functions of a neighbor solicitation message? (Choose two.)

  A. It requests the link-layer address of the target.
  B. It provides its own link-layer address to the target.
  C. It requests the site-local address of the target.
  D. It provides its own site-local address to the target.
  E. It requests the admin-local address of the target.
  F. It provides its own admin-local address to the target.
  A. It requests the link-layer address of the target.
  B. It provides its own link-layer address to the target.

  Neighbor solicitation messages are sent on the local link when a node wants to determine the link-layer address of another node on the same local link (see the figure below). When a node wants to determine the link-layer address of another node, the source address in a neighbor solicitation message is the IPv6 address of the node sending the neighbor solicitation message. The destination address in the neighbor solicitation message is the solicited-node multicast address that corresponds to the IPv6 address of the destination node. The neighbor solicitation message also includes the link-layer address of the source node.

  Figure 1. IPv6 Neighbor Discovery: Neighbor Solicitation Message After receiving the neighbor solicitation message, the destination node replies by sending a neighbor advertisement message, which has a value of 136 in the Type field of the ICMP packet header, on the local link. The source address in the neighbor advertisement message is the IPv6 address of the node (more specifically, the IPv6 address of the node interface) sending the neighbor advertisement message. The destination address in the neighbor advertisement message is the IPv6 address of the node that sent the neighbor solicitation message. The data portion of the neighbor advertisement message includes the link- layer address of the node sending the neighbor advertisement message. After the source node receives the neighbor advertisement, the source node and destination node can communicate.

• Question 207:

  What is the main function of VRF-lite?

  A. To allow devices to use labels to make Layer 2 Path decisions
  B. To segregate multiple routing tables on a single device
  C. To connect different autonomous systems together to share routes
  D. To route IPv6 traffic across an IPv4 backbone
  B. To segregate multiple routing tables on a single device

• Question 208:

  What is a reason to use DHCPv6 on a network that uses SLAAC?

  A. To get a record of the IPs that are used by the clients
  B. To push DNS and other information to the clients
  C. No reason, because there is no need for DHCPv6 when using SLAAC
  D. Because DHCPv6 can be used only in stateful mode with SLAAC to record the IPs of the clients
  E. Because DHCPv6 can be used only in stateless mode with SLAAC to record the IPs of the clients
  F. Because DHCPv6 is required to use first-hop security features on the switches
  B. To push DNS and other information to the clients

  SLAAC is by far the easiest way to configure IPv6 addresses, simply because you don't have to configure any IPv6 address. With SLAAC, a host uses the IPv6 Neighbor Discovery Protocol (NDP) to determine its IP address and default routers. Using SLAAC, a host requests and listens for Router Advertisements (RA) messages, and then taking the prefix that is advertised to form a unique address that can be used on the network. For this to work, the prefix that is advertised must advertise a prefix length of 64 bits (i.e., /64). But the most significant of Stateless Address Autoconfiguration (SLAAC) is it provided no mechanism for configuring DNS resolver information.Therefore SLACC can be used along with DHCPv6 (Stateless) to push DNS and other information to the clients.
