QUESTION 1Into which in turn standard protocol are LDP hello there communications encapsulated?

A. IPB. TCPC. UDPD. MPLS

Answer: CLDP Hello mail messages will be delivered on UDP convey 646

QUESTION 2Given the examples below LSP configuration, which assertion is definitely 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 apply path1 any time it truly is out there along with stable.B. The router will apply path3 when the item can be purchased and stable.C. The router will certainly make an attempt to identify path2 only when path1 in addition to path3 are generally down.D. The router will certainly attempt to identify path1 only when path2 along with path3 are generally down.

Answer: AAn LSP may have zero or even a single primary method applied. When it really is configured this primarypath should be used when it's offered from the network.

QUESTION 3What is the optimize timer upon an RSVP-signaled Label-Switched Path (LSP)?

A. the time it will take to recognize the suitable route for the LSPB. this phase that that ingress router recalculates the particular LSP's pathC. enough time the actual ingress router calls for in order to confirm the principal path JN0-303

D. the utmost amount of times that ingress router attempts to ascertain the principal path

Answer: BOnce a strong LSP features been established, topology or even resources alterations might, more than time, makethe avenue suboptimal. You can configure the ingress router that will recompute tracks periodicallyto determine whether a more ideal journey is now available. The rate of recurrence involving thiscalculation will be collection because of the enhance timer command around JUNOS.

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

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

Answer: A, B, DThe PathErr meaning trip upstream on the ingress router and also denotes a strong problem along theestablished path. The ResvErr vacations downstream that will your egress router and symbolizes anerror down the set up path. The ResvConf communication is a message delivered to this egressrouter with ask for confirming that Resv message appeared to be received.

QUESTION 5Which is a step within the JUNOS program CSPF algorithm?

A. Prune inbound links which can be bidirectional.B. Eliminate paths by using not enough MTU.C. Eliminate tracks involving in excess of 15 hops.D. Prune hyperlinks that will don't contain that incorporated admin group.

Answer: DOne point associated with visitors anthropological inside ability to be able to manipulate precisely what types of targeted traffic apply certainnetwork links. One method for hitting this kind of administrative goal is usually your make use of ofadministrative groups. When a strong LSP requires a community path inclusive of linksbelonging to be able to an administrative group, this CSPF criteria eliminates just about all back links which don'tcontain this requested group value.

QUESTION 6What becomes necessary to allow utilization of metrics larger in comparison with 63 to get traffic engineeringin IS-IS?

A. Nothing, wide metrics utilized by default in IS-IS.B. Enable wide-metrics-only within protocol IS-IS.C. Enable traffic-engineering under standards IS-IS.D. Disable TVL's a couple of and 128 that carry the 6-bit metrics (0-63). JN0-303

Answer: BTo correctly market a metric worth above 63, some sort of router must permit theadvertisement of "wide metrics" when using the wide-metrics-only command within just theappropriate IS-IS level. This control informs the neighborhood router to only give the particular widemetric TLVs (types 22 and 135).

QUESTION 7In JUNOS software, which will command is needed to help configure TED support pertaining to OSPF?

A. set protocols rsvp cspf-enableB. collection protocols mpls cspf-enableC. set standards rsvp traffic-engineeringD. set methods ospf traffic-engineering

Answer: DThe OSPF standard protocol makes use of your form 10 Opaque LSA intended for marketing and advertising trafficengineering details with some sort of network. Traffic architectural is usually enable considering the commandset traffic-engineering inside the protocols/ospf configuration hierarchy.

QUESTION 8An OSPF non-backbone region comes after external routes for being crammed inside the area.These exterior tracks tend to be spread into different areas. However, alternative routesfrom different areas will not be authorized to be able to get into this kind of area.Which method of OSPF community does this describe?

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

Answer: DAn OSPF not-so-stubby-area can be created as soon as an if not stub area incorporates a will need toconnect to a great alternative network as a result of an ASBR. An NSSA enables the shot ofexternal redirecting knowledge through a good ASBR using a good NSSA external LSA, form rule 7.

QUESTION 9In JUNOS software, that which is forced to dedistribute RIP routes straight into OSPF?

A. Apply an move insurance plan in RIP.B. Apply a strong import policy throughout RIP.C. Apply an upload policy throughout OSPF.D. Apply a strong import insurance plan around OSPF.

Answer: CBy default, this OSPF protocol can have very little perception of channels coming from other routingprotocols which includes RIP. On some sort of Juniper router, routing policies widely-used to redistribute
