• Question 334:

  Which of the following descriptions about uRPF loose mode is correct? (Choose two).

  A. It is typically used on point-to-point interfaces where the same interface is used for both directions of packet flows; if the source address has a return route in the FIB table, it is then checked against the adjacency table to ensure the same interface receiving the packet is the same interface used for the return path
  B. If a packet fails the uRPF loose mode check, the packet is then transmitted and creates a log message
  C. It is typically used on multipoint interfaces or on routers where asymmetrical routing is used (packets are received on one interface but the return path is not on the same interface); loose mode verifies a source address by looking in forwarding information base(FIB).
  D. If a packet fails the uRPF loose mode check, the packet is then dropped
  C. It is typically used on multipoint interfaces or on routers where asymmetrical routing is used (packets are received on one interface but the return path is not on the same interface); loose mode verifies a source address by looking in forwarding information base(FIB).
  D. If a packet fails the uRPF loose mode check, the packet is then dropped

  When administrators use Unicast RPF in strict mode, the packet must be received on the interface that the router would use to forward the return packet. Unicast RPF configured in strict mode may drop legitimate traffic that is received on an interface that was not the router's choice for sending return traffic. Dropping this legitimate traffic could occur when asymmetric routing paths are present in the network.

  When administrators use Unicast RPF in loose mode, the source address must appear in the routing table.

  Administrators can change this behavior using the allow-default option, which allows the use of the default route in the source verification process. Additionally, a packet that contains a source address for which the return route points to the Null 0 interface will be dropped. An access list may also be specified that permits or denies certain source addresses in Unicast RPF loose mode. Care must be taken to ensure that the appropriate Unicast RPF mode (loose or strict) is configured during the deployment of this feature because it can drop legitimate traffic. Although asymmetric traffic flows may be of concern when deploying this feature, Unicast RPF loose mode is a scalable option for networks that contain asymmetric routing paths.

• Question 340:

  Which 4 statements regarding MPLS Label Stack Encoding is true?

  A. A value of 4 represents the "Implicit NULL Label."
  B. A value of 0 represents the "IPv4 Explicit NULL Label."
  C. A value of 1 represents the "Router Alert Label".
  D. A value of 2 represents the "IPv6 Explicit NULL Label"
  E. A value of 1 represents the "IPv1 Explicit NULL Label"
  F. A value of 3 represents the "Implicit NULL Label"
  B. A value of 0 represents the "IPv4 Explicit NULL Label."
  C. A value of 1 represents the "Router Alert Label".
  D. A value of 2 represents the "IPv6 Explicit NULL Label"
  F. A value of 3 represents the "Implicit NULL Label"

  ---

  A value of 0 represents the "IPv4 Explicit NULL Label". This label indicates that the label stack must be popped, and the packet forwarding must be based on the IPv4 header. This helps to keep Exp bits safe until the egress router. It is used in MPLS based QoS. A value of 1 represents the "Router Alert Label". When a received packet contains this label value at the top of the label stack, it is delivered to a local software module for processing. The actual packet forwarding is determined by the label beneath it in the stack. However, if the packet is forwarded further, the Router Alert Label should be pushed back onto the label stack before forwarding. The use of this label is analogous to the use of the "Router Alert Option" in IP packets (for example, ping with record route option)

  A value of 2 represents the "IPv6 Explicit NULL Label". It indicates that the label stack must be popped, and the packet forwarding must be based on the IPv6 header. A value of 3 represents the "Implicit NULL Label". This is a label that an LSR can assign and distribute. However, it never actually appears in the encapsulation. It indicates that the LSR pops the top label from the stack and forwards the rest of the packet (labeled or unlabeled) through the outgoing interface (as per the entry in Lfib). Although this value might never appear in the encapsulation, it needs to be specified in the Label Distribution Protocol, so a value is reserved.
