Which mroute state is created when Bidirectional PIM is deployed at a site?

  1. *,G
  2. MVPN Type-6
  3. MVPN Type-7
  4. S,G

Answer(s): A

Explanation:

Bidirectional PIM is a different flavor of multicast than what you are probably used to (sparse, dense and sparse-dense mode). Most multicast networks have a couple of sources and many receivers. Bidirectional PIM has been invented for networks where we have many sources and receivers talking to each other. An example of this is videoconferencing where it's not just 1 source with many listeners but all the participants are communicating with each other.
The downside of using PIM sparse mode with many active sources and receivers is that we will see many mroute state entries that can take quite some resources. Using PIM sparse mode the RP builds 2 entries:
(*,G)
(S,G)
When we use PIM bidirectional mode the RP will never build a (S,G) entry and we only allow the (*,G) entry for the shared tree. PIM routers will never build the
SPT (Shortest Path Tree) towards the source.

Which statement about the default gateway configuration of the vPC is true?

  1. Either switch can act as the active default gateway.
  2. N7K-1 acts as the default gateway for all traffic.
  3. N7K-2 forwards traffic that is destined for the default gateway by using the peer link.
  4. N7K-2 acts as the default gateway for all traffic.

Answer(s): A

Explanation:

In normal Hot Standby Router Protocol operation, the active HSRP interface answers ARP requests, but with a vPC, both HSRP interfaces (active and standby) can forward traffic.
The most significant difference between the HSRP implementation of a non-vPC configuration and a vPC configuration is that the HSRP MAC addresses of a vPC configuration are programmed with the G (gateway) flag on both systems, compared with a non-vPC configuration, in which only the active HSRP interface can program the MAC address with the G flag. Given this fact, routable traffic can be forwarded by both the vPC primary device (with
HSRP) and the vPC secondary device (with HSRP), with no need to send this traffic to the
HSRP primary device. Without this flag, traffic sent to the MAC address would not be routed.

A small remote office is set to connect to the regional hub site via NSSA ASBR.
Which type of LSA is sent to the remote office OSPF area?

  1. type 7 LSA
  2. type 1 LSA
  3. type 5 LSA
  4. type 3 LSA

Answer(s): A

Explanation:

The remote site is connected to the Hub site via an ASBR router. Hence, an ASBR router redistributes a non OSPF or an External route into the NSSA area which is a Type 7. There is no ABR router in the question.
