Question #6
Which address range is used for source-specific multicast?
  1. A
    239.0.0.0/8
  2. B
    233.0.0.0/8
  3. C
    232.0.0.0/8
  4. D
    224.2.0.0/16

Correct Answer:
C

Absolutely spot on! The range 232.0.0.0/8 is indeed designated for Source-Specific Multicast (SSM), primarily utilized in applications where clarity and source specificity are critical, like internet video streaming. The protocol works best within this range, so it’s a sweet spot for those types of multicast deployments.

Question #7
Which three configuration parameters must match on all switches within the same MSTP region? (Choose three.)
  1. A
    VLAN to instance mapping
  2. B
    revision level
  3. C
    configuration name
  4. D
    bridge priority
  5. E
    region name

Correct Answer:
BCE
chatbot-img GPT-4o - Answer
The correct answer is B, C, and E — revision level, configuration name, and region name. These parameters must be identical across all switches within the same MSTP region to ensure a unified operation of MSTP. The region name uniquely identifies the MSTP region, the configuration name facilitates consistency in settings across all switches, and the revision level aids in tracking updates or changes within the MSTP region. Incorrect parameters could lead to configuration inconsistencies causing potential network loops or segmentation.

Question #8
Which two statements are correct about the deployment of EVPN-VXLAN on QFX Series devices? (Choose two.)
  1. A
    Type 1 route advertisements always have the single-active flag set to 1.
  2. B
    Junos OS supports underlay replication for BUM traffic forwarding.
  3. C
    Junos OS supports ingress replication for BUM traffic forwarding.
  4. D
    Type 1 route advertisements always have the single-active flag set to 0.

Correct Answer:
BC
chatbot-img GPT-4o - Answer
Junos OS indeed supports both underlay and ingress replication for BUM traffic in EVPN-VXLAN environments. Underlay replication leverages the physical network while ingress replication uses source-based replication over the IP network. It's vital to understand Junos OS capabilities in this context for effective deployment and troubleshooting on QFX devices. While there is a debate on the nature of Type 1 routes regarding the single-active flag, the focus on BUM traffic handling correctly reflects the support for multiple replication strategies in Junos.

Question #9
Your enterprise network is running BGP VPNs to support multitenancy. Some of the devices with which you peer BGP do not support the VPN NLRI. You must ensure that you do not send BGP VPN routes to the remote peer.
Which two configuration steps will satisfy this requirement? (Choose two.)
  1. A
    Configure an import policy on the remote peer to reject the routes when they are received.
  2. B
    Configure an export policy on the local BGP peer to reject the VPN routes being sent to the remote peer.
  3. C
    Configure a route reflector for the VPN NLRI.
  4. D
    Configure the apply-vpn-export feature on the local BGP peer.

Correct Answer:
BD
chatbot-img GPT-4o - Answer
Oh right, so when getting your network to not overshare its BGP VPN routes with peers that can’t handle them, you definitely gotta tweak your local settings rather than hoping the remote side will sort it out. Directly controlling your BGP exports by rejecting VPN routes through an export policy is a sharp move. Also, by using the apply-vpn-export feature, your local BGP peer smartly filters out these routes for setups that don't support VPN NLRI. This way you keep things clean and prevent unnecessary routing info from reaching incapable devices—nice and tidy!

Question #10
You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
In this scenario, which area is needed to accomplish this task?
  1. A
    totally non-to-stubby area
  2. B
    totally stubby area
  3. C
    stub area
  4. D
    non-to-stubby area

Correct Answer:
B
chatbot-img GPT-4o - Answer
Correct, a totally stubby area is designed to contain only default routes and intra-area routes in the form of Type 1 and 2 LSAs. This area type effectively filters out all routes except those generated within the area itself and a default route provided by the area border router, simplifying the routing table and decreasing the routing overhead within the area. This setup ensures minimal route advertisements while maintaining necessary connectivity for the area's devices.
