Referring to the exhibit, which two statements are correct? (Choose two.)
- A . The BGP neighbor can advertise L3 VPN related routes.
- B . The BGP neighbor cannot advertise EVPN related routes.
- C . The BGP neighbor can advertise EVPN related routes.
- D . The BGP neighbor cannot advertise L3 VPN related routes.
Referring to the exhibit, which two statements are correct? (Choose two.)
- A . The maximum wattage that this switch can allocate to attached Ethernet devices is 100 watts.
- B . If the total power consumption exceeds 90 watts, the ge-0/0/11 interface will continue to receive power.
- C . PoE is not enabled on the ge-0/0/0 interface.
- D . The ge-0/0/10 interface supports PoE+.
Referring to the exhibit, how will router E quickly learn that the remote MAC addresses are no longer reachable through the router attached to the failed link?
- A . Router E receives Type 2 withdrawal messages from router D.
- B . Router E receives Type 1 withdrawal messages from router D.
- C . Router E receives Type 1 withdrawal messages from router C.
- D . Router E receives Type 2 withdrawal messages from router C.
You are deploying new Juniper EX Series switches in a network that currently is using Cisco’s Per-VLAN spanning tree plus (PVST+) and you must provide compatibility with this environment.
Which spanning tree protocol do you deploy in this scenario?
- A . STP
- B . MSTP
- C . VSTP
- D . RSTP
Referring to the exhibit, anycast RP is implemented to ensure multicast service availability.
The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information.
In this scenario, what are two methods to receive the active source information on R2? (Choose two.)
- A . Configure an RP set in PIM on R1, allowing R1 to forward PIM register messages to R2 and R3 in the set.
- B . Configure an MSDP protocol between R2 and R3.
- C . Configure an RP set in PIM on R2 and R3, allowing the RPs to forward PIM register messages to the other RPs in the set.
- D . Configure an MSDP protocol between R1 and R2.
You are troubleshooting an EVPN-VXLAN IP fabric and observe the loop shown in the exhibit.
Which two steps would you take to further troubleshoot this problem? (Choose two.)
- A . Verify that the same ESI is configured on the link from the host and that it matches the source.
- B . Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present.
- C . Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present.
- D . Verify that the same ESI is configured on the two links from the source.
A user is attempting to watch a high-definition video being streamed from the media server over the network. However, the user complains that the experienced video quality is poor. While logged on to router B, a Juniper Networks device, you notice that video packets are being dropped.
In this scenario, what would solve this problem?
- A . Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.
- B . Adjust the expedited-forwarding BA classifier to router B’s ge-0/0/0 interface to support a higher transmit rate.
- C . Adjust the scheduler-map to support a higher transmit rate.
- D . Adjust the expedited-forwarding BA classifier on router B’s ge-0/0/1 interface to support a higher transmit rate.
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.)
- A . Configure the multipath option at the [edit protocols bgp group <group-name> neighbor] hierarchy.
- B . Configure the multipath option at the [edit protocols bgp group] hierarchy.
- C . Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding-table] hierarchy.
- D . Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy.
You must ensure that all routes in the 10.0.0/8 address range are not advertised outside of your AS.
Which well-known BGP community should be assigned to these addresses to accomplish this task?
- A . no-export
- B . no-peer
- C . internet
- D . no-advertise
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?
- A . MAC RADIUS
- B . captive portal
- C . 802.1X with single-secure supplicant mode
- D . 802.1X with multiple supplicant mode
