• 233.0.0.0/8
• 232.0.0.0/8
• 224.2.0.0/16

Which two statements are correct about the deployment of EVPN-VXLAN on QFX Series devices? (Choose two.)

• Type 1 route advertisements always have the single-active flag set to 1.
• Junos OS supports underlay replication for BUM traffic forwarding.
• Junos OS supports ingress replication for BUM traffic forwarding.
• Type 1 route advertisements always have the single-active flag set to 0.

Your network is multihomed to two ISPs. The BGP sessions are established; however, the ISP peers are not receiving any routes.Which two statements are correct about troubleshooting your configuration? (Choose two.)

• Verify the import policies on your router.
• Verify that the BGP routes are active in your routing table.
• Verify the export policies on your router.
• Verity that the multihop settings are configured on your router.

You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically negotiate the power requirements for the new connection with the EX Series switches.In this scenario, which protocol should be used to enable this behavior?

• CDP
• MP-BGP
• LLDP-MED
• LLDP

In OSPF, how does a router ensure that LSAs advertised to a neighboring router are received?

• LSA flooding guarantees that all routers will receive them successfully.
• LSAs are sent over a TCP connection.
• LSAs are acknowledged by the neighboring router.
• LSAs are advertised with an acknowledgement bit.

Your enterprise network uses routing instances to support multitenancy. Your Junos devices use BGP to peer to multiple BGP devices. You must ensure that load balancing is achieved within the routing instance.Which two statements would accomplish this task? (Choose two.)

• Configure the multipath option at the [edit protocols bgp group neighbor] hierarchy.
• Configure the multipath option at the [edit protocols bgp group] hierarchy.
• Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding-table] hierarchy.
• Configure the multipath option at the [edit routing-instances routing-options] hierarchy.

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?

• MAC RADIUS
• captive portal
• 802.1X with single-secure supplicant mode
• 802.1X with multiple supplicant mode

Which three configuration parameters must match on all switches within the same MSTP region? (Choose three.)

• VLAN to instance mapping
• revision level
• configuration name
• bridge priority
• region name

Which three statements are correct about EVPN route types? (Choose three.)

• Type 3 routes carry replication information.
• Type 2 routes carry endpoint MAC address information.
• Type 2 routes carry endpoint IP address information.
• Type 5 routes carry replication information.
• Type 1 routes carry endpoint MAC address information.

You are asked to enforce user authentication using a captive portal before users access the corporate network.Which statement is correct in this scenario?

• HTTPS is the default protocol for a captive portal.
• A captive portal can be bypassed using an allowlist command containing a device's IP address.
• When enabled, a captive portal must be applied to each individual interface.
• All Web browser requests are redirected to the captive portal until authentication is successful.
