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

• A.  EX Series devices flood LLDP frames across a Layer 2 domain to calculate a network topology.
• B.  EX Series devices support LLDP-MED power negotiation, enabling dynamic allocation of PoE power based on endpoint device needs.
• C.  LLDP only operates on interfaces configured for Layer 2.
• D.  LLDP-MED focuses on discovering network connectivity devices like routers and switches.

You are deploying IP phones in your enterprise network that must receive their power through their Ethernet connection. You are using your EX Series switch's PoE ports that support IEEE

• A.  50 W
• B.  30 W
• C.  15.4 W

Which two statements are correct about configuring OSPFv3 on a Junos OS router? (Choose two.)

• A.  You must configure the IPsec transport mode to secure OSPFv3 communication.
• B.  The OSPFv3 router ID is inherited from the configured IPv4 address on the Io0 interface.
• C.  The subnet and subnet mask must match for an adjacency to form.
• D.  You must configure the family inet6 parameter on the logical interface.

Which two statements are correct about IPv4 multicast to Ethernet address mapping? (Choose two.)

• A.  ARP is used to resolve IPv4 multicast addresses to the corresponding multicast Ethernet addresses.
• B.  Multiple IPv4 multicast addresses can map to a single multicast Ethernet MAC.
• C.  The first 23 bits of an IPv4 multicast address are used when mapping to the corresponding Ethernet address.
• D.  Multicast Ethernet MAC addresses always start with 01:00:5E.

You have a P-VLAN that spans multiple switches. In this scenario, how do you enable communication across the P-VLAN?

• A.  Configure trunk ports with inter-switch-link on the switches.
• B.  Configure trunk ports with isolated-vlan <vlan-id> on the switches.
• C.  Configure trunk ports with private-vlan community on the switches.
• D.  Configure trunk ports with private-vlan isolated on the switches.
