Enterprise Routing and Switching, Professional (JNCIP-ENT) certification is ideal for individuals who work with Juniper Networks routers and switches in a business environment. JN0-649 exam tests the knowledge and skills required to configure, troubleshoot, and maintain Juniper Networks devices.   Q35. 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. The forbidden mode does not register or declare VLANs. You can change the registration mode of a specific interface to forbidden. An interface in forbidden registration mode does not participate in MVRP even if MVRP is enabled on the switch.https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/mvrp.html MVRP is disabled by default on the switches and, when enabled, affects only trunk interfaces. Once you enable MVRP, all VLAN interfaces on the switch belong to MVRP (the default normal registration mode) and those interfaces accept PDU messages and send their own PDU messages. forbidden-The interface does not register or declare VLANS (except statically configured VLANs).Q36. 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. BUM Traffic ForwardingJunos devices that use MPLS encapsulation for EVPNs can only use ingress replication at this time.Ingress replication means, to flood traffic to remote PE routers, the traffic has to be replicated, once for each remote PE router.The EVPN label for this BUM traffic is learned per PE router from the route type 3, inclusive multicast Ethernet tag route.This table shows the format of the inclusive multicast Ethernet tag route.All-Active Redundancy (4)This diagram shows the format of the type 1 route, A-D route per ES. The split horizon label is advertised as part of an extended community attached to the type 1 route. The split horizon label is also called the ESI label. The extended community also indicates what type of redundancy mode is used for this given ESI: single-active represented by binary 1 or active-active represented by binary 0.Q37. You have PIM SM multicast configure and running in a network environment comprised of EX4300 devices. Your customer report increased delay when switching channels using IPTV. To help decrease the delay, you implement PIM join balancing. You add the set protocol pim join- load-balance command to the configuration. After committing, you notice that the flows are still using one path.In this scenario, which statement is correct?  The interface must be specified to use for load balancing  PIM join load-balancing also be configured.  IGMP snooping must be configured.  The clear pim join-distribution command must be issued. Q38. Referring to the exhibit, a PIM-SM network is set up to enable communication between multicast devices.Which two statements are true? (Choose two.)  Before the formation of the rendezvous-point tree, a join message is sent from R1 to R3.  Before the formation of the rendezvous-point tree, an IGMP is sent from the Receiver to R1.  Before the formation of the rendezvous-point tree, an IGMP is sent from the Source to R5.  Before the formation of the rendezvous-point tree, a join message is sent from R1 to R5. Q39. Your network has an unmanaged switch between the hosts and your EX Series switch. After the traffic enters the EX Series switch, each host must be on a separate VLAN.How would you accomplish this task?  Configure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs.  Configure an output firewall filter on interface ge-0/0/1 to match the destination MAC or IP address of the hosts to assign the VLANs.  Configure interface ge-0/0/3 to a mode trunk to assign the VLANs.  Configure VSTP on interface ge-0/0/1 to assign the VLANs. Q40. What is a supplicant in 802.1x authentication?  the device that prevents the end user device’s access until it is authenticated  the authenticating device  the device being authenticated  the RADIUS server Q41. You want to provide Layer 2 connectivity between campus sites using Ethernet switches through a metro Ethernet service provider who is using Q-in-Q tagging on their network.Referring to the exhibit, what are two design considerations in this environment? (Choose two.)  VXLAN could be implemented on your network across this service provider network.  Each campus switch shown must have a C-Tag 300 configured.  L2PT is required on the SP network to support the spanning tree protocol.  Each campus switch shown must have S-Tag 300 configured. Q42. Which address range is used for source-specific multicast?  239.0.0.0/8  233.0.0.0/8  232.0.0.0/8  224.2.0.0/16 PIM SSM introduces new terms for many of the concepts in PIM sparse mode. PIM SSM can technically be used in the entire 224/4 multicast address range, although PIM SSM operation is guaranteed only in the 232/8 range (232.0.0/24 is reserved). The new SSM terms are appropriate for Internet video applications and are summarized in Table 1. https://www.juniper.net/documentation/us/en/software/junos/multicast/topics/concept/multicast-pim-ssm.htmlQ43. Which two authentication methods are available for OSPF on Juniper devices? (Choose two.)  RSA  MD5 authentication  none  Certificate Q44. A modified deficit round-robin scheduler is defined by which three variables? (Choose three.)  priority  WRED  transmit rate  Layer 3 fields  buffer size Q45. You are troubleshooting an OSPF adjacency issue between R1 and R2.What is the reason for the ExStart state shown in the exhibit?  R2 was elected as the designated router.  R1 was elected as the backup designated router.  R1 and R2 are using the same IP address.  The MTU is not the default on R1 and R2. Q46. 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 Single supplicant mode authenticates only the first end device that connects to an authenticator port. All other end devices connecting to the authenticator port after the first has connected successfully, whether they are 802.1X-enabled or not, are permitted access to the port without further authentication. If the first authenticated end device logs out, all other end devices are locked out until an end device authenticates. Single-secure supplicant mode authenticates only one end device to connect to an authenticator port. No other end device can connect to the authenticator port until the first logs out.Q47. Click the Exhibit.You have just configured on an OSPF adjacency between two routers. After you commit the configuration, you notice that your adjacency is not up.Referring to the exhibit, what would cause the problem?  You must configure lo on R2.  You must configure hello and dead intervals on R1.  You must configure on interface-type o n R2.  You must configure bfd on R2. Q48. Referring to the exhibit, which two statements are correct? (Choose two.)  The host that the route is associated with is multihomed to two leaf nodes.  The route is a Type 1 EVPN route.  The route is a Type 2 EVPN route.  The host that the route is associated with is single-homed to one leaf node. Q49. 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 https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/concept/evpn-route-type5-understanding.html#:~:text=In%20the%20control%20plane%2C%20EVPN,subnet%20connectivity%20across%20data%20centers.Q50. There are two BGP routes to 10.200.200.0/24 received from two external peers. Route 1 comes from a neighbor with a router ID of 10.10.100.1 and a peer IP address of 10.10.30.1, and route 2 comes from a neighbor with a router ID of 10.10.200.1 and a peer IP address of 10.10.50.1. Both routes have the same MED value, origin value, AS path length, and local preference number. In this scenario, which statement is correct about the active route?  Route 1 will be active because of the peer IP address.  Route 2 will be active because of the peer IP address.  Route 1 will be active because of the router ID.  Route 2 will be active because of the router ID. Q51. Which two port modes are associated with STP? (Choose two.)  alternate port  backup port  designated  root Q52. Which BGP message type contains NLRI information?  notification  keepalive  update  open Q53. Referring to the exhibit, how is R1 learning the route from R2?  R2 has interface ge-0/0/2 configured in another area under OSPFv3.  R2 has an export policy with external type 1 configured.  R2 has interface ge-0/0/2 configured as a passive interface under OSPFv3.  R2 has an export policy with external type 2 configured. Q54. You are troubleshooting a route problem in the topology shown in the exhibit. The 10.30.0 0/24 route is not reachable from the R3 router. What would cause this problem?  R3 does not have a route to the BGP next hop of 10.30.0.0/24  R4 is not advertising the 10.30.0.0/24 route to R3  R3 does not have an established BGP session with R4.  R3 does not have an OSPF route for 10.30.0.0/24 Q55. 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. Q56. 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.  Loading … Juniper JN0-649 exam is a valuable certification exam for IT professionals looking to advance their career in enterprise routing and switching.
