Question 16

Which two statements are correct about EVPN/VXLAN deployments? (Choose two.)

  1. VNIs are used for encapsulating and de-encapsulating traffic entering and leaving the tunnels.
  2. VTEPs are used for encapsulating and de-encapsulating traffic entering and leaving the tunnels.
  3. VTEPs are used to identify broadcast domains within an EVPN/VXLAN environment.
  4. VNIs are used to identify broadcast domains within an EVPN/VXLAN environment.

Question 17

Which statement accurately describes the operation of OSPF within the Junos OS?

  1. OSPF calculates routes using a distance vector algorithm.
  2. OSPF is used for routing information and neighbor discovery within a single autonomous system (AS).
  3. OSPF does not automatically advertise directly connected routes.
  4. OSPF is used for routing information and neighbor discovery between multiple autonomous systems.

Question 18

You run a multivendor switching environment where you have configured VSTP. You have 450 VLANs and notice that some of your VLANs do not function properly. How should you change the configuration to get all 450 VLANs working?

  1. Include the force-version stp; statement in your configuration.
  2. Enable RSTP to handle additional VLANs.
  3. Set the VLAN max-age to 3600 or more.
  4. Increase the bridge priority on all VLANs to at least 16k.

Question 19

Click the Exhibit button. Referring to the exhibit, which two statements are correct? (Choose two.)

  1. The bandwidth reservation for queue 0 is 76%.
  2. During times of no network congestion, traffic that is placed in queue 2 will be dropped if more than 10% of the interface bandwidth is used.
  3. The bandwidth reservation for queue 0 is 100%.
  4. During times of sustained network congestion, traffic that is placed in queue 2 will be dropped if more than 10% of the interface bandwidth is used.

Question 20

Click the Exhibit button. You need to configure the non-RP routers in your network to dynamically learn the location of the RP using standard protocols only. You have already applied the configuration shown in the exhibit, but the routers have not learned the location of the RP. Which additional step must you take to fulfill these requirements?

  1. Configure MSDP.
  2. Configure BSR.
  3. Configure Anycast RP.
  4. Configure Auto-RP.
