Question #11
Click the Exhibit button.

Referring to the exhibit, which two statements are true? (Choose two.)
  1. A
    The multihop configuration is used for load balancing.
  2. B
    This route is learned from the same AS number.
  3. C
    This route is learned from two different AS numbers.
  4. D
    The multipath configuration is used for load balancing.

Correct Answer:
BD

Question #12
A packet is received on an interface configured with transmission scheduling. One of the configured queues is exceeding the allocated bandwidth.
In this scenario, which two actions will be taken by default on a Junos device? (Choose two.)
  1. A
    The exceeding queue will be considered to have negative bandwidth credit.
  2. B
    The excess traffic will be discarded.
  3. C
    The exceeding queue will be considered to have positive bandwidth credit.
  4. D
    The excess traffic will use bandwidth available from other queues.

Correct Answer:
BD

It is crucial to understand that when a queue exceeds its allocated bandwidth on a Junos device, the system manages this by discarding the excess traffic and by using available bandwidth from other queues. This ensures that traffic flow remains as efficient as possible while adhering to the predefined QoS settings. This behavior helps maintain network stability and efficiency, avoiding the potential pitfalls of bandwidth congestion by redistributing the load. Therefore, the default responses of discarding surplus traffic and utilizing spare bandwidth from other queues are both critical mechanisms to handle overload situations effectively.

Question #13
Which two statements are correct about a sham link? (Choose two.)
  1. A
    The PEs exchange Type 1 OSPF LSAs instead of Type 3 OSPF LSAs for the L3VPN routes.
  2. B
    It creates an OSPF multihop neighborship between two PE routers.
  3. C
    It creates a BGP multihop neighborship between two PE routers.
  4. D
    The PEs exchange Type 3 OSPF LSAs instead of Type 1 OSPF LSAs for the L3VPN routes.

Correct Answer:
AB
chatbot-img GPT-4o - Answer
Professor's Comment: A sham link is utilized in MPLS VPN OSPF configurations primarily to ensure that intra-area OSPF traffic between sites travels through the MPLS network rather than taking less optimal inter-area paths through the backbone. The reason a sham link exists is to offer a direct, virtual intra-area link between Provider Edge (PE) routers. This link allows for the exchange of Type 1 OSPF LSAs, which are crucial for maintaining accurate intra-area routing information and establishing a more direct, logical connectivity. Understanding this concept is fundamental for optimizing OSPF operations within an L3VPN scenario.

Question #14
Click the Exhibit button.

R4 is directly connected to both RPs (R2 and R3). R4 is currently sending all joins upstream to R3 but you want all joins to go to R2 instead.
Referring to the exhibit, which configuration change will solve this issue?
  1. A
    Change the bootstrap priority on R2 to be higher than R3.
  2. B
    Change the local address on R2 to be higher than R3.
  3. C
    Change the default route in inet.2 on R4 from R3 as the next hop to R2.
  4. D
    Change the group-range to be more specific on R2 than R3.

Correct Answer:
A

Question #15
Which two statements are correct regarding the PIM DR in a PIM-SM domain? (Choose two.)
  1. A
    By default. PIM DR election is performed on point-to-point links.
  2. B
    If the DR priorities match, the router with the lowest IP address is selected as the DR.
  3. C
    The source DR sends PIM register messages from the source network to the RP.
  4. D
    The receiver DR sends PIM join and PIM prune messages from the receiver network toward the RP.

Correct Answer:
CD
chatbot-img GPT-4o - Answer
Absolutely, let's clarify a couple of things here about PIM DR in a Sparse Mode scenario: The DR closest to the IP source, often just referred to as the 'source DR,' plays a specific role by handling PIM Register messages which are essentially responsible for initiating the process whereby multicast traffic from a source is encapsulated into unicast for delivery to the Rendezvous Point (RP). Also, the DR near the receiver (the 'receiver DR') is different in its duties—this is the router taking charge of sending PIM Join and Prune messages towards the RP to manage which multicast streams are needed or not needed by hosts within its network. This helps in managing bandwidth and providing efficient routing paths for multicast traffic.
