Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) Sample Questions (Q50-Q55):

NEW QUESTION # 50
A new network requires multiple topology support. You decide to use IS-IS in this situation. Which three protocol topologies are supported in this scenario? (Choose three.)

Answer: A,D,E

Explanation:
Explanation
IS-IS (Intermediate System to Intermediate System) is a routing protocol that is designed to move information efficiently within a computer network12. It supports multiple protocol topologies, including IPv4, IPv6, and multicast12. Therefore, options C, E, and D are correct.


NEW QUESTION # 51
You are asked to create a default route that will be advertised to your internal OSPF neighbors. You have three upstream connections to the Internet and you must ensure that when available, all traffic uses ISP1 as your primary connection and only uses ISP2 and ISP3 when ISP1 is not available.
Which solution should you implement in this scenario?

Answer: A

Explanation:
The solution that should be implemented in this scenario is to create a default generate route that includes an import policy to match BGP routes from ISP1 and assign a preference value of four or less. This way, the default route will be advertised to the internal OSPF neighbors only when there is a BGP route from ISP1 in the routing table, and it will have a higher preference than any other default route from ISP2 or ISP3. If ISP1 is not available, the default generate route will be withdrawn and the traffic will use the next available default route from ISP2 or ISP3.
Option A is incorrect because creating a default static route with ISP1's address as the next hop while specifying the addresses for ISP2 and ISP3 as qualified next hops with a preference value of six or higher will not ensure that the default route is advertised to the internal OSPF neighbors only when ISP1 is available. The default static route will always be in the routing table regardless of the availability of ISP1, and it will have a lower preference than any other default route from ISP2 or ISP3.
Option C is incorrect because creating a default static route with each neighbor address as the next hop will not ensure that all traffic uses ISP1 as the primary connection and only uses ISP2 and ISP3 when ISP1 is not available. The default static route will always be in the routing table regardless of the availability of ISP1, and it will load balance the traffic among the three ISPs.
Option D is incorrect because creating a default aggregated route will not ensure that the default route is advertised to the internal OSPF neighbors only when ISP1 is available. The default aggregated route will always be in the routing table regardless of the availability of ISP1, and it will not have any preference value associated with it. References:

NEW QUESTION # 52
Your network has two ISPs available. You want to ensure that all outbound traffic is routed out ISP-1. If the connection to ISP-1 fails, all outbound traffic is routed to the backup ISP ISP-2. In this scenario, how should you configure BGP on your network?

Answer: C


NEW QUESTION # 53
Which two statements are correct about using firewall filters on EX Series switches? (Choose two.)

Answer: A,D

Explanation:
* A is correct because you can deploy only stateless firewall filters on an EX Series switch. A stateless firewall filter is a filter that evaluates each packet individually based on the header information, such as source and destination addresses, protocol, and port numbers 1 . A stateless firewall filter does not keep track of the state or context of a packet flow, such as the sequence number, flags, or session information
1 . EX Series switches support only stateless firewall filters, which are also called access control lists (ACLs) or packet filters 2 .
* C is correct because you can apply firewall filters to both Layer 2 and Layer 3 traffic on an EX Series switch. Layer 2 traffic is traffic that is switched within a VLAN or a bridge domain, while Layer 3 traffic is traffic that is routed between VLANs or networks 3 . EX Series switches support three types of firewall filters: port (Layer 2) firewall filters, VLAN firewall filters, and router (Layer 3) firewall filters 4 . You can apply these filters to different interfaces and directions to control the traffic entering or exiting the switch.


NEW QUESTION # 54
Exhibit

Referring to the exhibit, which two configuration changes must you apply for packets to reach from R1 to R3 using IS-IS? (Choose two.)

Answer: B,C

Explanation:
Explanation
A: On R1, enable Level 1 on the ge-0/0/1 interface. In IS-IS, both levels (Level 1 and Level 2) are enabled by default when you enable IS-IS on an interface1. Level 1 systems route within an area2. If the destination is outside an area, Level 1 systems route toward a Level 2 system2. Therefore, enabling Level 1 on the ge-0/0/1 interface on R1 would allow packets to reach from R1 to R3.
D: On R3 enable Level 1 on the ge-0/0/4 interface Similarly, enabling Level 1 on the ge-0/0/4 interface on R3 would allow packets to reach from R1 to R3.
These explanations are based on the IS-IS configuration documents and learning resources available at Juniper Networks1 and Cisco34.
