List of questions
Question 11

Exhibit
Which prefix in the output shown in the exhibit is an external prefix injected by an OSPF router?
192.168.1.3
172.18.1.0/24
192.108.1.4
172.26.4.0730
In the OSPF routing table output, prefixes are marked with different route types. An external prefix injected into OSPF is marked as 'Ext' (External) followed by a number that indicates whether it's an E1 or E2 route. The prefix 172.18.1.0/24 is marked as Ext2, which indicates that it is an external route that has been redistributed into OSPF from another routing protocol or static configuration.

Question 12

Which statement describes integrated routing and bridging (IRB) interfaces?
An IRB interface Is an IP gateway For hosts of a bridge domain.
An IRB interface assigns interfaces to VLANs.
An IRB interface enables Layer 2 switching on the router.
An IRB interface defines a bridge domain.
An Integrated Routing and Bridging (IRB) interface is used to provide Layer 3 routing services to hosts within a bridge domain. The IRB acts as a default gateway for hosts in that domain, enabling communication with other networks.

Question 13

Exhibit
The LSP is not establishing correctly.
Referring to the exhibit, what should you do to solve the problem?
Enable traffic engineering for the OSPF protocol.
Enable traffic engineering for the IS-IS protocol.
Enable traffic engineering for the BGP protocol.
Enable traffic engineering for the RSVP protocol.
The exhibit shows that the Label Switched Path (LSP) is down. One common reason for this could be that the IGP is not providing traffic engineering information to the MPLS process. Since the exhibit shows the OSPF configuration, enabling traffic engineering extensions for OSPF would allow OSPF to distribute the labels and traffic engineering information necessary for LSP establishment.

Question 14

You are bringing a new network online with three MX Series devices enabled for STP. No root bridge priority has been configured. Which statement is true in this scenario?
The device with the lowest MAC address will be elected as the root bridge.
The device with the highest MAC address will be elected as the root bridge.
The device with the lowest numerical lo0 IP address will be elected as the root bridge.
The device with the highest numerical lo0 IP address will be elected as The bridge.
https://supportportal.juniper.net/s/article/EX-Identify-the-Root-Bridge-in-a-Spanning-Tree-STP-network?language=en_US The root bridge in a spanning-tree network is the bridge with the smallest or the lowest bridge ID.
In the absence of a manually configured priority, the Spanning Tree Protocol (STP) elects the root bridge based on the lowest bridge ID, which is a combination of the priority and the MAC address. The device with the lowest MAC address will have the lowest bridge ID and thus be elected as the root bridge.

Question 15

What Is a key differentiator of generate routes from aggregate routes?
Generate routes use a forwarding next hop.
Generate routes have a default next-hop value of reject.
Generate routes have a default preference value of 210.
Generate routes cannot be used as a gateway of last resort.
https://www.networkfuntimes.com/junos-aggregate-routes-vs-generate-routes-how-to-summarise-on-juniper-routers/
Generated routes are a type of route that can be created to summarize and generate more specific routes within the routing table. Unlike aggregate routes, which summarize existing routes and inherit a next-hop, generated routes do not necessarily have to match an existing route and will have a next-hop of reject by default unless specified otherwise.

Question 16

Which statement is correct about the FE80;:/10 prefix?
This prefix range is used for the link local address.
This prefix range is used on the loopback interface.
This prefix range is reserved for multicast applications
This prefix range is not reserved.
The FE80::/10 prefix is reserved for IPv6 link-local addresses. These addresses are auto-configured on all IPv6-enabled interfaces and can be used for communication within the local link (subnet) only.

Question 17

You are asked to create connections between routing instances on the same Junos device and route between the connected Instances. What are two ways to accomplish this task? (Choose two.)
Question 18

Which configuration selling prohibits a static route from being redistributed by a dynamic routing protocol?
Question 19

What is the correct order of BGP attributes for active route selection?
Question 20

What are three well-known mandatory BGP attributes? (Choose three.)
