Question 1
Exhibit button
Which two statements are correct about the service provider MPLS network shown in the exhibit? (Choose two.)
R3 will perform a label pop operation on the transport MPLS label.
Traffic from Network 1 to Network 3 and traffic from Network 1 to Network 4 each need their own unique label-switched path.
Traffic from Network 1 to Network 3 and from Network 1 to Network 4 can share the same label-switched path.
R3 will perform a label swap operation on the transport MPLS label.
In MPLS, multiple paths can be merged if they share the same egress router. In the given scenario, traffic from Network 1 to Network 3 and Network 4 can be engineered to follow the same label-switched path (LSP) within the MPLS network until they reach the last common point before diverging to their respective destinations.
As for R3 performing label operations, in a typical MPLS network, intermediate routers (like R3) perform label swapping. They replace the incoming label with a new label before forwarding the packet along the LSP. A label pop operation is typically performed by the egress router in the case of an ultimate hop pop (UHP), where it removes the MPLS label before delivering the packet to the final destination outside the MPLS domain.

Question 2
Which two statements are correct when using LDP? (Choose two.)
The lnet.3 table will contain only the paths explicitly defined.
The inet.3 table will contain a full mesh of label-switched paths to other LDP-enabled routers.
LDP label-switched paths are created by configuring LDP on at least one physical router interface.
LDP label-switched paths are created by configuring LDP on the loopbacK Interface.
With Label Distribution Protocol (LDP), a full mesh of label-switched paths (LSPs) is automatically created between all LDP-enabled routers, and these paths are reflected in the inet.3 table. LDP LSPs are set up when LDP is enabled on interfaces connecting routers in an MPLS network.

Question 3
Which two interface types are used as tunnel endpoints? (Choose two.)
ae
ip
ge
gr
tunnel-end-point name {
ipv4 {
source-address 10.255.1.1;
destination-address 10.255.2.0/25;
}
gre {
key 9;
}
}
https://www.juniper.net/documentation/us/en/software/junos/routing-policy/topics/ref/statement/tunnel-end-point-edit-firewall.html
The ip and gr interface types are used as endpoints for various tunneling protocols. ip is a generic term that can refer to any IP-based tunnel, while gr specifically refers to Generic Routing Encapsulation (GRE) tunnel interfaces in Junos.

Question 4
Exhibit
The exhibit shows a topology with 1 Gbps interfaces between routers, and four RSVP LSPs operating with the respective bandwidth reservations.
Which path will be selected for a new LSP from R4 to R6 with a bandwidth reservation of 400 Mbps?
R4 -> R1 -> R2 -> R5 -> R6
R4 -> R5 -> R6
R4 -> R5 -> R2 -> R3 -> R6
R4 -> R1 -> R2 -> R3 -> R6
Considering the bandwidth reservations shown, the only path from R4 to R6 that has sufficient available bandwidth for a new LSP with 400 Mbps reservation is via R1, R2, and R5. This is because the R4-R5 direct link and the R4-R1-R2-R3-R6 path do not have enough unreserved bandwidth to accommodate an additional 400 Mbps LSP.

Question 5
Which two statements are correct about IS-IS? (Choose two.)
A level 1 only router can never form an adjacency with a level 2 only router.
For level 2 adjacencies, the area IDs can be different.
For level 2 adjacencies, the area IDs must be the same.
A level 1 only router can form an adjacency with a level 2 only router.
A Level 1 router can become adjacent with the Level 1 and Level 1-2 (L1/L2) router. A Level 2 router can become adjacent with Level 2 or Level 1-2 (L1/L2) router. There is no adjacency between L1 only and L2 only router. HOWEVER: If two routers are in different areas, they can only form a Level 2 adjacency. As such, two routers in different areas can NOT form a Level 1 adjacency. If you want two routers to form a Level 1 adjacency, they have to be in the same area.
IS-IS (Intermediate System to Intermediate System) operates at two levels: Level 1 and Level 2. Level 1 routers are only aware of their own area's topology, while Level 2 routers have knowledge of the topology across areas. A Level 1 router cannot form an adjacency with a Level 2 router unless the Level 2 router is also operating as a Level 1 router (Level 1-2 router). Level 2 routers can form adjacencies regardless of their area IDs because Level 2 operates at the domain level and is used to interconnect different IS-IS areas.

Question 6
You are adding an IPv6 configuration to an Interface on a Junos device.
In this scenario, which statement is correct?
The link local address must be manually configured within the fdO0::/8 prefix range.
The link local address must be manually configured within the fe80::/10 prefix range.
The link local address is automatically created using the MAC address within the fe80::'l0 prefix range.
The link local address is automatically created using the MAC address within the fd00::/8 prefix range.
IPv6 link-local addresses are automatically generated for each interface and have a prefix of fe80::/10. The interface's MAC address is typically used as part of the process to create the Interface Identifier (IID) in the link-local address, following the EUI-64 format.

Question 7
Which statement is correct about IS-IS?
IS-IS is a distance vector routing protocol.
IS-IS is a path vector routing protocol.
IS-IS is a link-state routing protocol.
IS-IS is a classful routing protocol.
IS-IS is a link-state routing protocol that uses a Shortest Path First (SPF) algorithm to create a topology map of the network. It floods link-state advertisements (LSAs) to all nodes within the network area to ensure each node has a consistent view of the network topology.

Question 8
Which new field is added to an IPv6 header as compared lo IPv4?
version
checksum
fragment offset
flow label
The IPv6 header includes a new field that is not found in the IPv4 header, called the flow label. The flow label in IPv6 is used to identify packets that require special handling by routers for quality of service (QoS) or other reasons, allowing these packets to be handled efficiently as they move through the network.

Question 9
Interface ge-0/0/0.0 connecls yout network to your ISP. You want to advertise this interface address as an Internal route In OSPF without creating a neighbor with your ISP.
In this scenario, how is this task accomplished?
Remove interface ge-0/0/0.0 from OSPF.
Create a generated route for Interface ge-0/0/0.0.
Add ge-0/0/0.0 as a passive interface In OSPF.
Configure a static route for Interface ge-0/0/0.0.
When you want to advertise an interface in OSPF but not form an OSPF adjacency over that interface (for example, towards an ISP), you can configure the interface as passive. This will advertise the network on the interface in OSPF without sending OSPF hello packets or forming OSPF neighbor relationships on that interface.

Question 10
What are two types of SlDs used in segment touting? (Choose two.)
node
adjacency
link
interface
In segment routing, SIDs (Segment Identifiers) are used to identify different types of segments that can be traversed. A node SID represents an instruction to route a packet to a particular node, and an adjacency SID represents an instruction to route a packet over a specific link or adjacency between two nodes.
