NEW QUESTION # 14
When would you use the qualified-next-hop statement with a static route?
- A. You can use it to resolve the next hop if the next hop is not directly connected.
- B. You can use it to send unwanted traffic to a null route.
- C. You can use it to specify multiple next hops with different preferences.
- D. You can use it to install the static route into different routing tables.
Answer: C
Explanation:
https://www.juniper.net/documentation/us/en/software/junos/static-routing/topics/ref/statement/qualified-next-hop-edit-routing-options.html
https://www.juniper.net/documentation/us/en/software/junos/static-routing/topics/topic-map/static-route-prefer-qualified-next-hop.html: Qualified next hops allow you to associate one or more properties with a particular next-hop address. You can set an overall preference for a particular static route and then specify a different preference for the qualified next hop. For example, suppose two next-hop addresses (10.10.10.10 and 10.10.10.7) are associated with the static route 192.168.47.5/32. A general preference is assigned to the entire static route, and then a different preference is assigned to only the qualified next-hop address 10.10.10.7. For example:
The qualified-next-hop statement with a static route is used to specify multiple next hops for a static route with different preferences (priorities). This allows for more granular control over the path selection process in the event that the primary next hop becomes unreachable.

NEW QUESTION # 15
Which two statements are correct about segment routing? (Choose two.)
- A. Label assignments can be advertised through LDP updates.
- B. There are no segment routing adjacencies to maintain.
- C. Label assignments can be advertised through OSPF updates.
- D. Segment routing adjacencies require very little resources to maintain.
Answer: C,D
Explanation:
Segment routing is a source routing paradigm that allows a source router to define the path that a packet will take through the network by assigning an ordered list of segments-identifiers that specify a forwarding path for the packet through the network. Segment Routing can be implemented over an MPLS architecture or with IPv6 (SRv6).
A . Segment routing does not require a full mesh of adjacencies or state per transit path in the network, which is often the case with conventional MPLS signaling protocols like RSVP-TE. It leverages the existing IGP topology for forwarding without the need to maintain a state for each LSP (Label Switched Path), hence requiring very little resources to maintain.
B . In segment routing, labels (or segments) are distributed via IGP routing protocols like OSPF or IS-IS with extensions to carry segment routing information. These protocols are enhanced with Segment Routing extensions to distribute labels. For example, OSPFv2 is extended with Segment Routing extensions defined in RFC 8665.
C . This statement is not entirely correct. While it is true that segment routing does not require the maintenance of a state for each path (LSP), the concept of "segment routing adjacencies" is a mischaracterization. Segment routing leverages the existing adjacencies formed by the underlying IGP.
D . Label assignments in segment routing are not advertised through LDP (Label Distribution Protocol) updates. Segment routing does away with LDP and instead uses IGP extensions to distribute labels.

NEW QUESTION # 16
Exhibit
Referring to the exhibit, what must be included in the Route1 configuration when establishing an EBGP session with the ISP?
- A. The BGP session type internal must be specified.
- B. The BGP session type external must be specified.
- C. A local address must be specified.
- D. A local AS must be specified.
Answer: C
Explanation:
When establishing an EBGP session, it's necessary to specify both the local AS number and the local address that the session will use. The local address is required for establishing the TCP connection for BGP. The local AS must be specified to identify the autonomous system of the router.References:

NEW QUESTION # 17
Exhibit
You are asked to configure the OSPF environment to prevent the DRother routers from participating in DR/BDR election.

- A. set protocols ospf area 0.0.0.0 interface ge-0/0/1 interface-type nbma
- B. set protocols ospf area 0.0.0.0 interface ge-0/0/1 interface-type p2p

- D. set protocols ospf area 0.0.0.0 interface ge-0/0/l priority 255
Answer: D
NEW QUESTION # 18
Exhibit
Referring to the exhibit, what is the minimum number of LSPs required to support alt four networks?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Given the RSVP Signaled Service Provider MPLS Core network shown in the exhibit, only a single Label Switched Path (LSP) is required to support all four networks because MPLS can use label stacking to multiplex multiple LSPs over a single physical path. Therefore, one LSP can be established through the MPLS core, and all networks can use this LSP with different label stacks.References:

NEW QUESTION # 20
You are asked to configure filter-based forwarding on a Junos device.
Which two statements are correct in this scenario? (Choose two.)
- A. You must create a route target.
- B. You must create a routing instance.
- C. You must create a routing policy.
- D. You must create and apply a match filter.
Answer: B,D
Explanation:
To configure filter-based forwarding, perform the following tasks:
- Create a match filter on the ingress device. To specify a match filter, include the filter filter-name statement at the [edit firewall] hierarchy level. A packet that passes through the filter is compared against a set of rules to classify it and to determine its membership in a set. Once classified, the packet is forwarded to a routing table specified in the accept action in the filter description language. The routing table then forwards the packet to the next hop that corresponds to the destination address entry in the table.
- Create routing instances that specify the routing table(s) to which a packet is forwarded, and the destination to which the packet is forwarded at the [edit routing- instances] hierarchy level.
NEW QUESTION # 21
Exhibit
You are asked to configure OSPF between routers R1 and R2 using IPv6 addresses.
Which two tasks will accomplish your objective? (Choose two.)
- A. Issue the sec protocols ospf area 0.0.0.0 interface ge-0/0/1.0 command.
- B. Under the [edit routing-options] hierarchy, configure a 32-bit router ID.
- C. Under the [edit routing-options] hierarchy, configure a 128-bit router ID.
- D. issue the set protocols ospf3 area 0.0.0.0 interface ge-0/0/1.0 command.
Answer: B,D
Explanation:
To configure OSPFv3 (the version of OSPF that supports IPv6), you would use the set protocols ospf3 command with the appropriate area and interface. OSPFv3 requires a 32-bit router ID just like OSPFv2, which is typically an IPv4 address. OSPF does not use a 128-bit router ID, so answer D is incorrect.

NEW QUESTION # 26
Exhibit
Which two statements are correct about the service provider MPLS network shown in the exhibit? (Choose two.)
- A. R3 is considered a P router.
- B. R3 is considered a transit router.
- C. R3 is considered an ingress router.
- D. R3 is considered a PE router.
Answer: A,B
Explanation:
In a service provider MPLS network, P routers are interior routers that are used to transit MPLS-labeled packets between edge routers but do not attach or remove MPLS labels themselves. These routers are also referred to as transit routers. They are neither ingress nor egress routers (which are typically labeled as PE routers).
