7 B. Local preference is evaluated early in the BGP route selection process and results in the route with the lowest numerical local preference being selected. C. Local preference is used to break ties when all other received BGP attributes are otherwise equal. D. Local preference is sent by an EBGP speaker to a neighboring AS in an attempt to influence how the remote peer's traffic will ingress into your network. Answer: A NO.15 Click the Exhibit button. Which statement is true regarding the output shown in the exhibit? A. The configuration supports IPv4 multicast routes. B. The configuration supports IPv4 unicast routes. C. The configuration supports IPv6 unicast routes. D. The configuration supports IPv6 multicast routes. Answer: C Explanation: By default, OSPFv3 supports unicast IPv6 routes, but you can configure OSPFv3 to support multiple address families. To support an address family other than unicast IPv6, you configure a realm that allows OSPFv3 to advertise IPv4 unicast, IPv4 multicast, or IPv6 multicast routes. Example of a configuration which support both Ipv4 and Ipv6 prefixes: user@host# show protocols ospf3 realm ipv4-unicast { area { interface fe-0/1/0.0; area { interface fe-0/1/0.0; References: multiple-address-families.html NO.16 You have configured MPLS and RSVP in your network using all of the Junos defaults. You established an LSP in your network which is reporting an up status but no traffic is using it. Which two statements reflect potential causes for this issue? (Choose two) A. The LSP egress address is a physical interface address B. family MPLS was omitted from the router configurations C. No BGP routes are being advertised from the remote neighbor D. The LSP egress address does not match the BGP next-hop address Answer: C,D NO.17 Which statement correctly describes unified in-service software upgrades (ISSU)? Get Latest & Valid JN0-360 Exam's Question and Answers 6 from Certshiken.com. 6

8 A. Unified ISSU is built upon graceful-restart extensions to allow upgrades with no impact to the data plane. B. Unified ISSU is supported on systems with single or dual Routing Engines. C. Unified ISSU permits both upgrades and downgrades with no control plane disruption and is based on the graceful Routing Engine switchover (GRES) feature. D. Unified ISSU is based on nonstop-routing (NSR) and graceful Routing Engine switchover (GRES), and permits software upgrades only. Answer: D NO.18 For a network running single-area OSPF, how would you decrease the size of the link-state database (LSDB)? A. Implement RIP as an overlay protocol on all devices. B. Add more devices to the OSPF network to help with LSDB processing. C. Reduce the frequency of hello timers throughout the network. D. Implement OSPF areas.
