Passing the Juniper Service Provider Routing and Switching, Specialist exam was a great achievement for me, and I owe a big thanks to Pass4Success practice questions for helping me prepare. The OSPF section of the exam was particularly challenging, with questions on Router ID and OSPF functionality. One question that I found difficult was about the different OSPF packet types and their purposes. Despite my initial uncertainty, I managed to remember the details from my practice questions and successfully answer the question.

The OSPF section of the exam was quite detailed, covering topics like Link-state database and OSPF packet types. Thanks to Pass4Success practice questions, I was able to grasp the nuances of OSPF operations. One question that I remember from the exam was about OSPF adjacencies and neighbors, and how they impact routing decisions. It was a tricky question, but I was able to recall the information I learned from the practice questions and answer it correctly.

Question #1

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

Reveal Solution Hide Solution
Correct Answer: A, B, E

https://www.catchpoint.com/bgp-monitoring/bgp-attributes

BGP Attribute Categories

There are four categories of BGP attributes:

Well-known mandatory:Recognized by all BGP peers, passed to all peers, and present in all Update messages. Well-known mandatory attributes include:- Next-hop- Origin- AS PATH

Well-known discretionary:Recognized by all routers, passed to all peers, and optionally included in the Update message. Well-known discretionary attributes include:- Local Preference- Atomic Aggregate

Optional transitive:Possibly recognized by BGP routers and passed to BGP peers. Optional transitive attributes are marked as partial when not recognized. Optional transitive attributes include:- Aggregator- Community

Optional non-transitive:Possibly recognized by BGP routers but not passed to peers. Optional non-transitive attributes include:- Multi-exit discriminator (MED)- Originator ID- Cluster-ID

The three well-known mandatory BGP attributes that must be present in every BGP update message are:

Next Hop: Indicates the next hop IP address to reach the advertising BGP peer.

Origin: Indicates how the route was originated, whether it was via IGP, EGP, or incomplete.

AS Path: Lists the autonomous systems that the update has traversed.

Question #2

Exhibit

Referring to the exhibit, how do you verify the status of the tunnel from R1?

Reveal Solution Hide Solution
Correct Answer: C

Question #3

Exhibit

Which two statements are correct about the service provider MPLS network shown in the exhibit? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, C

Question #4

Exhibit

Which type of load balancing is shown in the exhibit?

Reveal Solution Hide Solution
Correct Answer: B

The policy statement shown in the exhibit has a term that specifies load-balance per-packet, which indicates that per-packet load balancing is being used. This means that the routing device will distribute packets out multiple paths on a per-packet basis, rather than on a per-flow (per-destination or per-source-destination pair) basis.

Question #5

How does a Junos device learn about MAC addresses when II is first connected to an Ethernet LAN?

Reveal Solution Hide Solution
Correct Answer: C

Junos devices learn about MAC addresses by examining the source MAC address of frames received on an interface and then storing these MAC addresses in the MAC address table (also known as the forwarding database) along with the interface on which the traffic was received. Reference::
