QUESTION 1Into that protocol are LDP hello messages encapsulated?

A. IPB. TCPC. UDPD. MPLS

Answer: CLDP Hello emails usually are sent on UDP port 646

QUESTION 2Given the examples below LSP configuration, which assertion is true?label-switched-pathlsp-xyz {to 10.2000.1.1;primarypath1;secondarypath2;secondarypath3;no-cspf;}pathpath1 {10.200.10.1 strict;}pathpath2 {10.200.20.1 strict;}pathpath3 {10.200.30.1loose}

A. The router will work with path1 while it can be obtainable and stable.B. The router could make use of path3 when it really is available and stable.C. The router will certainly make an effort to establish path2 only when path1 as well as path3 usually are down.D. The router will attempt to confirm path1 only if path2 in addition to path3 usually are down.

Answer: AAn LSP will surely have absolutely no or one particular main path applied. When it truly is configured the actual primarypath has to be utilized in case it really is accessible in the particular network.

QUESTION 3What will be enhance timer on an RSVP-signaled Label-Switched Path (LSP)?

A. some time it will take to recognize the actual optimal method to get this LSPB. your time period that the ingress router recalculates the particular LSP's pathC. time this ingress router uses to establish the most important journey JN0-303

D. the ideal availablility of instances the particular ingress router will try to be able to establish the primary path

Answer: BOnce a strong LSP features been recently established, topology or maybe sources variations might, above time, makethe avenue suboptimal. You can configure your ingress router to recompute pathways periodicallyto ascertain whether a more optimum path has turn into available. The regularity regarding thiscalculation is defined through the optimize timer receive inside JUNOS.

QUESTION 4What are generally three RSVP messages? (Choose three.)

A. PathErr: Path errorB. ResvErr: Reservation errorC. PathConf: Path confirmationD. ResvConf: Reservation confirmation

Answer: A, B, DThe PathErr message moves upstream to the ingress router and also denotes an error along theestablished path. The ResvErr moves downstream on the egress router and denotes anerror under the recognized path. The ResvConf principles is a information provided for the egressrouter upon demand confirming this Resv meaning was received.

QUESTION 5Which is really a step in the JUNOS computer software CSPF algorithm?

A. Prune inbound links that happen to be bidirectional.B. Eliminate walkways together with deficiency of MTU.C. Eliminate driveways and walkways connected with above 15 hops.D. Prune links that never incorporate your incorporated administrative group.

Answer: DOne aspect with page views anthropological while in the ability to overpower what forms of targeted traffic employ certainnetwork links. One way for accomplishing this administrative goal may be the make use of ofadministrative groups. When an LSP requires a system route that features linksbelonging to be able to a strong admin group, the CSPF criteria removes most backlinks this don'tcontain the requested party value.

QUESTION 6What is needed to make it possible for the employment of metrics bigger compared to 63 for traffic engineeringin IS-IS?

A. Nothing, wide metrics utilized by default within IS-IS.B. Enable wide-metrics-only less than process IS-IS.C. Enable traffic-engineering within protocols IS-IS.D. Disable TVL's 2 in addition to 128 that bring the particular 6-bit metrics (0-63). JN0-303

Answer: BTo appropriately publicize a metric price higher than 63, some sort of router must help theadvertisement regarding "wide metrics" using the wide-metrics-only command line within theappropriate IS-IS level. This command updates a nearby router in order to just post the actual widemetric TLVs (types twenty two along with 135).

QUESTION 7In JUNOS software, which command can be used for you to configure TED service pertaining to OSPF?

A. fixed protocols rsvp cspf-enableB. fixed protocols mpls cspf-enableC. fixed methods rsvp traffic-engineeringD. arranged networks ospf traffic-engineering

Answer: DThe OSPF protocol utilizes a style 10 Opaque LSA pertaining to promoting trafficengineering information in a network. Traffic archaeologist is enable with the commandset traffic-engineering within the protocols/ospf configuration hierarchy.

QUESTION 8An OSPF non-backbone place follows outside routes to become inundated inside area.These exterior routes are propagated into other areas. However, outer routesfrom additional spots aren't allowed in order to enter this particular area.Which type of OSPF location does that describe?

A. stub areaB. transit areaC. line areaD. not-so-stubby area

Answer: DAn OSPF not-so-stubby-area is actually produced while a good if not stub area possesses your have toconnect to an alternative circle through an ASBR. An NSSA provides for that shot ofexternal redirecting knowledge simply by an ASBR employing an NSSA exterior LSA, kind rule 7.

QUESTION 9In JUNOS software, exactly what becomes necessary that will dedistribute RIP paths directly into OSPF?

A. Apply an move policy within RIP.B. Apply an import scheme throughout RIP.C. Apply a great move policy in OSPF.D. Apply a strong scan plan around OSPF.

Answer: CBy default, the OSPF protocol will present no understanding associated with channels from other routingprotocols including RIP. On a new Juniper router, redirecting guidelines usually are made use of to redistribute
