Free JN0-364: Service Provider Routing and Switching - Specialist (JNCIS-SP) Exam Questions and Answers

You configure a static route on R1 for a lab prefix, but the route does not appear in the routing table. Referring to the exhibit, which action causes the route to be installed in inet.0? Exhibit: user@R1> show configuration routing-options static { route 240.10.0.0/16 next-hop 10.0.0.2; } user@R1> show route 10.0.0.2 inet.0: 7 destinations, 7 routes (7 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 10.0.0.0/30 *[Direct/0] 00:41:12 > via ge-0/0/0.0 10.0.0.1/32 *[Local/0] 00:41:12 Local via ge-0/0/0.0 user@R1> show route 240.10.0.0/16 user@R1>

• AA. set routing-options static route 240.10.0.0/16 resolve
• BB. set routing-options static route 240.10.0.0/16 retain
• CC. set routing-options static route 240.10.0.0/16 no-readvertise

Which operational mode command displays the contents of the IS-IS link-state database on a Junos device?

• AA. show isis interface
• BB. show isis database
• CC. show isis adjacency
• DD. show isis route

An ASBR in OSPF NSSA area 10 redistributes several static routes. The ABR connecting area 10 to area 0 translates these routes before advertising them into the backbone. Which LSA type does the ABR use to advertise these routes into area 0?

• AA. Type 4 ASBR Summary LSA
• BB. Type 3 Network Summary LSA
• CC. Type 5 AS External LSA
• DD. Type 7 NSSA External LSA

You are configuring a GRE tunnel interface gr-0/0/0.0 on R1 to connect to R2 across a provider network. Which two statements are correct in this scenario? (Choose two.)

Select 2 answers.

• AA. The route to the tunnel destination address must not be learned through the tunnel itself
• BB. The tunnel source and destination addresses are configured under the unit of the gr- interface
• CC. A GRE key must be configured and match on both ends or the tunnel interface remains down
• DD. The gr- interface must be configured with family inet6 even when it carries only IPv4 traffic

Which OSPF packet type carries a summary of the LSA headers in the link-state database while two neighbors are forming an adjacency?

• AA. Link State Update
• BB. Hello
• CC. Database Description
• DD. Link State Request

You enable IS-IS on interface ge-0/0/1.0 under protocols isis, but no adjacency forms with the directly connected router. Which additional interface configuration is required on a Junos device for IS-IS to operate?

• AA. family iso, with a NET configured on the loopback interface
• BB. family inet6 with an IPv6 link-local address
• CC. family mpls with the interface listed under protocols mpls
• DD. family inet with a /31 subnet mask on the interface

Which BGP attribute is well-known mandatory and must be included in every UPDATE message that advertises reachable prefixes?

• AA. AS_PATH
• BB. MULTI_EXIT_DISC
• CC. COMMUNITY
• DD. LOCAL_PREF

You configure a LAG between R1 and R2 using two member links. Both member interfaces are physically up, but ae0 stays down on both routers. Referring to the exhibit, what should you do to bring up the LAG? Exhibit: user@R1# show interfaces ae0 aggregated-ether-options { lacp { passive; } } unit 0 { family inet { address 172.16.1.1/30; } } user@R2# show interfaces ae0 aggregated-ether-options { lacp { passive; } } unit 0 { family inet { address 172.16.1.2/30; } }

• AA. Configure periodic fast under the lacp hierarchy on both routers
• BB. Configure link-protection under aggregated-ether-options on both routers
• CC. Configure lacp active on at least one of the routers
• DD. Configure minimum-links 1 under aggregated-ether-options on both routers

Which source address does an OSPFv3 router use when it sends Hello packets on an Ethernet interface?

• AA. The IPv4 router ID mapped into an IPv6 address
• BB. The IPv6 address configured on the lo0.0 interface
• CC. The link-local address of the interface
• DD. The global unicast address configured on the interface

Which operational mode command displays the label bindings that a Junos router has received from its LDP neighbors?

• AA. show mpls lsp
• BB. show ldp database
• CC. show ldp neighbor
• DD. show route table mpls.0
