Question #2
Click the Exhibit button.
Referring to the exhibit, anycast RP is implemented to ensure multicast service availability. The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information.
In this scenario, what are two methods to receive the active source information on R2? (Choose two.)

Question #3
You are asked to establish interface level authentication for users connecting to your network. You must ensure that only corporate devices, identified by MAC addresses, are allowed to connect and authenticate. Authentication must be handled by a centralized server to increase scalability.
Which authentication method would satisfy this requirement?
Which authentication method would satisfy this requirement?
- AMAC RADIUSMost Voted
- Bcaptive portal
- C802.1X with single-secure supplicant mode
- D802.1X with multiple supplicant mode
Correct Answer:
A
A

MAC RADIUS authentication effectively meets the criteria for enabling scalable interface-level authentication via a centralized server while ensuring only specifically permitted corporate devices connect. This technique leverages the organization's RADIUS server to validate devices based on their MAC addresses—prioritizing managed device access over others. This makes it an ideal choice for environments that need to balance security with device flexibility.

Question #5
You enable the Multiple VLAN Registration Protocol (MVRP) to automate the creation and management of virtual LANs.
Which statement is correct in this scenario?
Which statement is correct in this scenario?
- AThe forbidden mode does not register or declare VLANs.Most Voted
- BWhen enabled, MVRP affects all interfaces.
- CTimers dictate when link state changes are propagated.
- DMVRP works with RSTP and VSTP.
Correct Answer:
B
B

From the discussion and documentation, it's evident there's some confusion about MVRP's impact. When MVRP is enabled on Juniper devices, it does indeed affect all trunk interfaces, automating VLAN registration and declaration. This protocol doesn't apply to non-trunk or forbidden mode interfaces, which is where the confusion might stem from. Remember, MVRP participation is specific to interface settings, largely involving trunk links but not universally affecting all interface types. Understanding this selective application can clear up common misunderstandings regarding MVRP's operational scope in network settings.
