Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q27-Q32):

NEW QUESTION # 27
Exhibit

Referring to the exhibit, which three statements are correct about route 10 0 0.0/16 when using the default BGP advertisement rules'? (Choose three.)

• A. R1 will advertise 10.0.0.0/16 to R2 with 192 168 1 1 as the next hop.
• B. R1 will prepend AS 65531 when advertising 10 0.0 0/16 to R2.
• C. R4 will advertise 10 0.0 0/16 to R6 with 172.16 1 1 as the next hop
• D. R2 will advertise 10.0.0.0/16 to R4 with 172.16.1.1 as the next hop
• E. R2 will advertise 10.0.0.0/16 to R3 with 192.168.1 1 as the next hop

Answer: A,C,D

Explanation:
Explanation
The problem in this scenario is that R1 and R8 are not receiving each other's routes because of private AS numbers in the AS path. Private AS numbers are not globally unique and are not advertised to external BGP peers. To solve this problem, you need to do the following:
* Configure loops on routers in AS 65412 and advertise-peer-as on routers in AS 64498. This allows R5 and R6 to advertise their own AS number (65412) instead of their peer's AS number (64498) when sending updates to R7 and R8. This prevents a loop detection issue that would cause R7 and R8 to reject the routes from R5 and R62
* Configure remove-private on advertisements from AS 64497 toward AS 64498 and from AS 64500 toward AS 64499. This removes any private AS numbers from the AS path before sending updates to external BGP peers. This allows R2 and R3 to receive the routes from R1 and R4, respectively3.

NEW QUESTION # 28
Which origin code is preferred by BGP?

• A. Null
• B. External
• C. Internal
• D. Incomplete

Answer: D

Explanation:
Explanation
BGP uses several attributes to select the best path for a destination prefix. One of these attributes is origin, which indicates how BGP learned about a route. The origin attribute can have one of three values: IGP, EGP, or Incomplete. IGP means that the route was originated by a network or aggregate statement within BGP or by redistribution from an IGP into BGP. EGP means that the route was learned from an external BGP peer (this value is obsolete since BGP version 4). Incomplete means that the route was learned by some other means, such as redistribution from a static route into BGP. BGP prefers routes with lower origin values, so Incomplete is preferred over EGP, which is preferred over IGP.

NEW QUESTION # 29
Exhibit

The network shown in the exhibit is based on IS-IS
Which statement is correct in this scenario?

• A. The system IDofR1_2 is 192.168.16.1
• B. The NSEL byte for Area 0001 is 00.
• C. The area address is two bytes.
• D. The routers are using unnumbered interfaces

Answer: B

Explanation:
Explanation
IS-IS is an interior gateway protocol that uses link-state routing to exchange routing information among routers within a single autonomous system. IS-IS uses two types of addresses to identify routers and areas:
system ID and area address. The system ID is a unique identifier for each router in an IS-IS domain. The system ID is 6 octets long and can be derived from the MAC address or manually configured. The area address is a variable-length identifier for each area in an IS-IS domain. The area address can be 1 to 13 octets long and is composed of high-order octets of the address. An IS-IS instance may be assigned multiple area addresses, which are considered synonymous. Multiple synonymous area addresses are useful when merging or splitting areas in the domain1. In this question, we have a network based on IS-IS with four routers (R1_1, R1_2, R2_1, and R2_2) belonging to area 0001. The area address for area 0001 is 49.0001. The NSEL byte for area 0001 is the last octet of the address, which is 01. The NSEL byte stands for Network Service Access Point Selector (NSAP Selector) and indicates the type of service requested from the network layer2. Therefore, the correct statement in this scenario is that the NSEL byte for area 0001 is 01.

NEW QUESTION # 30
Exhibit

A network designer would like to create a summary route as shown in the exhibit, but the configuration is not working.
Which three configuration changes will create a summary route? (Choose three.)

• A. delete policy-options policy-statement leak-v6 term DC-routes from route-filter 2001: db9 :a: fa00 : :/6l longer
• B. set policy-options policy-statement leak-v6 term DC-routes from route-filter 2001:db9:a:faOO::/61 exact
• C. set protocols isis import summary-v6
• D. set policy-options policy-statement leak-v6 term DC-routes then reject
• E. delete protocols isis export summary-v6

Answer: A,B,E

Explanation:
Explanation
To create a summary route for IS-IS, you need to configure a policy statement that matches the prefixes to be summarized and sets the next-hop to discard. You also need to configure a summary-address statement under the IS-IS protocol hierarchy that references the policy statement. In this case, the policy statement leak-v6 is trying to match the prefix 2001:db9:a:fa00::/61 exactly, but this prefix is not advertised by any router in the network. Therefore, no summary route is created. To fix this, you need to delete the longer keyword from the route-filter term and change the prefix length to /61 exact. This will match any prefix that falls within the /61 range. You also need to delete the export statement under protocols isis, because this will export all routes that match the policy statement to other IS-IS routers, which is not desired for a summary route.

NEW QUESTION # 31
Exhibit

Referring to the exhibit, a working L3VPN exists that connects VPN-A sites CoS is configured correctly to match on the MPLS EXP bits of the LSP, but when traffic is sent from Site-1 to Site-2, PE-2 is not classifying the traffic correctly What should you do to solve the problem?

• A. Set a static CoS value for the PE-1_to_PE-2 LSP
• B. Configure VPN prefix mapping for the PE-1_to_PE-2 LSP
• C. Configure the explicit-null statement on PE-2
• D. Configure the explicit-null statement on PE-1.

Answer: D

Explanation:
Explanation
The explicit-null statement enables the PE router to send an MPLS label with a value of 0 (explicit null) instead of an IP header for packets destined to the VPN customer sites. This allows the penultimate hop router (the router before the egress PE router) to preserve the EXP bits of the MPLS label and pass them to the egress PE router. The egress PE router can then use these EXP bits to classify the traffic according to the CoS policy2
. In this example, PE-1 should configure the explicit-null statement under [edit protocols mpls label-switched-path PE-1_to_PE-2] hierarchy level.
