Your Layer 2 network uses 802.1X to authenticate user devices connecting to the network. You are asked to include a new Layer 2 interface connection from the conference room in your network. You must ensure that only a single device is allowed to authenticate on this port at one time to avoid users from being able to plug in a rogue switch to this port. In this scenario, which 802.1X method would you use for the new interface?

A. single-secure supplicant mode

B. multiple supplicant mode

C. single supplicant mode

D. MAC-RADIUS

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

A. VNIs are used for encapsulating and de-encapsulating traffic entering and leaving the tunnels

B. VTEPs are used for encapsulating and de-encapsulating traffic entering and leaving the tunnels.

C. VTEPs are used to identify broadcast domains within an EVPN/VXLAN environment.

D. VNIs are used to identify broadcast domains within an EVPN/VXLAN environment.

Exhibit

You configured MVRP in your Layer 2 network using the configuration shown in the exhibit. You verified that the appropnate VLANs are configured and applied on the two access switches. You are using RSTP as your loop prevention mechanism. Unfortunately, the users are not able to communicate with their corresponding server attached to the Access- 2 switch. In this scenario, what should you do to solve this problem?

A. Configure VSTP instead of RSTP as your loop-prevention mechanism.

B. Configure the access interfaces on the Access-2 switch under MVRP.

C. Configure the ge-070716.0 interface on the Core-1 switch under MVRP.

D. Configure the access interfaces on the Access-1 switch under MVRP.

You are troubleshooting a multicast deployment in a network. Some multicast groups operate in PIM-ASM mode and others operate in PIM-SSM mode. While troubleshooting, you note the following:
- The network uses IGMPv2 for some segments and IGMPv3 for others.
- For group 232.1.1.1, receivers know the exact source IP of the multicast sender
- For group 239.10.10.10. receivers do not know the source address in advance.
Which two statements correctly describe the operational differences between these two modes in Junos OS? (Choose two.)

A. PIM-ASM supports multiple active sources for a group without requiring receivers to know them in advance, whereas PIM-SSM requires explicit source knowledge

B. In PIM-ASM. the DR first sends a PIM register message to the RP before switching to the shortest-path tree.

C. PIM-SSM requires an RP for initial joins, whereas PIM-ASM can operate without one.

D. PIM-SSM relies on IGMPv3 to signal both the source and the group in the join message, bypassing the RP entirely.

Which statement about LLDP and LLDP-MED operations on EX Series devices is correct?

A. LLDP only operates on interfaces configured for Layer 2

B. EX Series devices flood LLDP frames across a Layer 2 domain to calculate a network topology

C. EX Series devices support LLDP-MED power negotiation, enabling dynamic allocation of PoE power based on endpoint device needs.

D. LLDP-MED focuses on discovering network connectivity devices like routers and switches.

You want to implement a system in your network to simplify VLAN management that can also dynamically create and prune VLANs. How would you accomplish this task?

A. Enable GVRP on access interfaces.

B. Enable MVRP and GVRP on all interfaces.

C. Enable MVRP on trunk interfaces.

D. Enable MVRP on access interfaces.

Which three statements about VSTP are correct? (Choose three.)

A. Separate BPDUs are Hooded for each VSTP enabled VLAN.

B. VSTP is incompatible with RSTR

C. VSTP is enabled by default on EX Series switches.

D. VSTP supports up to 253 unique spanning tree topologies.

E. A separate spanning tree instance is generated for each VLAN.

You need to perform maintenance on one of your OSPF routers. You do not want the other OSPF routers on the network to forward traffic to this router dunng the maintenance window Which OSPF configuration parameter would you implement to accomplish this task?

A. traffic-engineering

B. overload

C. preference

D. spf-options
