Which two statements are correct about multicast routing tables? (Choose two.)
- A . inet.0 is used for RPF checks.
- B . MBGP and IS-IS place routes in inet.1 directly
- C . inet.2 is used when the multicast forwarding topology differs from unicast forwarding.
- D . IS-IS and OSPFv3 place routes in inet.2 directly.
You want to validate a recursive lookup for an EVPN route designation.
Which route table query will accomplish this task?
- A . default-switch.evpn.0
- B . vxlan.inet.0
- C . inet.3
- D . inet.2
While deploying class of service on an EX Series switch, what are two aspects of the scheduler? (Choose two.)
- A . It defines interface rate-limiting.
- B . It defines a buffer size of the queue to which it is assigned.
- C . It identifies the priority of the queue to which it is assigned.
- D . It provides DiffServ code translation.
Your organization uses 802.1X with a RADIUS server. If the RADIUS server stops responding, you want the fallback action to continue to permit access for devices that currently have authorization but deny any new access attempts.
Which fallback action provides this capability?
- A . use-cache
- B . deny
- C . permit
- D . vlan-name

You want to provide better performance for the video traffic that traverses your network. The video traffic enters your network without any class-of-service markings.
According to Juniper Networks, which two classification methods are performed by the routers shown in the exhibit? (Choose two.)
- A . R2 and R3 perform multifield classification.
- B . R2 and R3 perform behavior aggregate classification.
- C . R1 performs multifield classification.
- D . R1 performs behavior aggregate classification.

Referring to the exhibit, R2 receives a packet from the multicast source on its ge-0/0/4.0 interface.
Which two statements are correct in this scenario? (Choose two.)
- A . All interfaces other than ge-0/0/4.0 will be on the outgoing interface list.
- B . R2 determines that the packet is coming in on an interface that is on the reverse path back to the source.
- C . The packet is discarded.
- D . R2 verifies the existing unicast routing table and determines that this interface is not on the reverse path back to the source.
When configuring OSPF, what is the purpose of adding the secondary command to an OSPF interface?
- A . The secondary command sets a backup path for virtual links.
- B . The secondary command allows an interface to be in multiple areas.
- C . The secondary command is used in conjunction with VRRP for failover.
- D . The secondary command creates an intra-area backup path.
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-SSM requires an RP for initial joins, whereas PIM-ASM can operate without one.
- B . PIM-SSM relies on IGMPv3 to signal both the source and the group in the join message, bypassing the RP entirely.
- C . PIM-ASM supports multiple active sources for a group without requiring receivers to know them in advance, whereas PIM-SSM requires explicit source knowledge.
- D . In PIM-ASM, the DR first sends a PIM register message to the RP before switching to the shortest-path tree.
You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically be provided with their geographic location details by the EX Series switches.
In this scenario, which protocol should be used to enable this behavior?
- A . LLDP-MED
- B . CDP
- C . LLDP
- D . MP-BGP
You have several switches in your network that use Cisco’s PVST+ protocol. You want your Juniper switches to interoperate with those devices.
In this scenario, which protocol would you use?
- A . VSTP
- B . MSTP
- C . RSTP
- D . RPVST+
