Free 4A0-101: Alcatel-Lucent Interior Routing Protocols Exam Questions and Answers
Alcatel-Lucent Interior Routing Protocols is exam 4A0-101, part of the Alcatel-Lucent Service Routing Certification programme from Alcatel-Lucent, now part of Nokia. Every exam here carries a 4A0- code, the numbering Alcatel-Lucent used for its carrier service-router track: 4A0-100 is the Scalable IP Networks entry paper, and the routing, MPLS, services, quality-of-service and multicast papers build on it. Nokia acquired Alcatel-Lucent's networking business in 2016 and runs this today as its Service Routing Certification programme, so the ladder these exams sit on — NRS I, then NRS II, then Service Routing Architect — is Nokia's, and the written papers are delivered through Pearson VUE.

Question #1
What is the primary function of the OSPF protocol in a network?
Please select an optionIncorrectCorrect answer: B
OSPF (Open Shortest Path First) is primarily used to route packets of data within a single Autonomous System (AS).
Was this answer correct?Question #2
In a large OSPF network, how does the protocol minimize the amount of traffic?
Please select an optionIncorrectCorrect answer: A
OSPF minimizes traffic by summarizing routes, which reduces the number of routing updates sent throughout the network.
Was this answer correct?Question #3
Which OSPF router is responsible for generating link-state advertisements (LSAs)?
Please select an optionIncorrectCorrect answer: C
The Designated Router (DR) generates LSAs for OSPF to ensure efficient communication in multi-access networks.
Was this answer correct?Question #4
What type of routing algorithm does IS-IS use?
Please select an optionIncorrectCorrect answer: C
IS-IS (Intermediate System to Intermediate System) uses a link-state routing algorithm for efficient data transmission.
Was this answer correct?Question #5
When configuring RIP, what is the maximum hop count allowed before a route is considered unreachable?
Please select an optionIncorrectCorrect answer: D
In RIP (Routing Information Protocol), a hop count of 16 is considered unreachable, limiting the effective range of the protocol.
Was this answer correct?Question #6
Which protocol uses the concept of areas to optimize routing?
Please select an optionIncorrectCorrect answer: A
OSPF uses areas to streamline routing and reduce the size of the routing table, allowing for efficient network management.
Was this answer correct?Question #7
What is a key advantage of using EIGRP over RIP?
Please select an optionIncorrectCorrect answer: C
EIGRP (Enhanced Interior Gateway Routing Protocol) supports load balancing over equal-cost and unequal-cost paths, which is a significant advantage over RIP.
Was this answer correct?Question #8
Which of the following statements is true about OSPF routers in the same area?
Please select an optionIncorrectCorrect answer: C
OSPF requires that all routers within the same area have unique router IDs to distinguish them and maintain efficient communication.
Was this answer correct?Question #9
In an EIGRP routing table, what does the term "successor" refer to?
Please select an optionIncorrectCorrect answer: A
The "successor" in EIGRP refers to the primary route to a destination network that is selected based on the best metrics.
Was this answer correct?Question #10
What are the main benefits of using route summarization?
Please select an optionIncorrectCorrect answer: B
Route summarization reduces the size of routing tables and limits routing updates, thereby minimizing unnecessary broadcast traffic.
