Free Enterprise Routing and Switching, Professional Exam JN0-649 Exam Practice Test

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.

You are deploying an 802.1X solution and must determine what would happen if clients are unable to re-authenticate to the RADIUS server.In this scenario, which configuration would provide access to the network if the supplicant is already authenticated?

• move
• permit
• deny
• sustain

Your EX Series switch has IP telephones and computers connected to a single switch port. You are considering implementing the voice VLAN feature to help with this setup.In this scenario, which two statements are correct? (Choose two.)

• The voice VLAN feature must be used with LLDP-MED to associate VLAN ID and 802.1p values with the traffic.
• The interfaces must be configured as access ports.
• Assigning the incoming voice and data traffic to separate VLANs enables the ability to prioritize the traffic using CoS.
• The voice VLAN feature will enable incoming tagged data and voice traffic to be associated with separate VLANs.

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

• forwarding delay
• bridge priority
• revision number
• MSTI-to-VLAN mapping
• configuration name

You are asked to configure 802.1X on your access ports to allow only a single device to authenticate.In this scenario, which configuration would you use?

• single supplicant mode
• multiple supplicant mode
• single-secure supplicant mode
• MAC authentication mode

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.

A Layer 2 connection does not expend across data centers. The IP subnet in a Layer 2 domain is confined within a single data center.Which EVPN route type is used to communicate prefixes between the data centers?

• Type 1
• Type 2
• Type 4
• Type 5

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 enable the Multiple VLAN Registration Protocol (MVRP) to automate the creation and management of virtual LANs.Which statement is correct in this scenario?

• The forbidden mode does not register or declare VLANs.
• When enabled, MVRP affects all interfaces.
• Timers dictate when link state changes are propagated.
• MVRP works with RSTP and VSTP.

You are implementing the route summarization feature of OSPF.Which two results do you achieve in this scenario? (Choose two.)

• It helps in migrating to future multi-area OSPF network designs.
• It reduced the routing table size, enabling devices to store and process less information.
• It reduces the impact of topology changes on a device.
• It provides optimal routing in the network.
