The Nokia NRS II Composite Exam (4A0-C04, OSPF version) is a 70-question, 120-minute multiple-choice test delivered through Pearson VUE for $375 USD with a 70% passing score. It combines four exams into one: OSPF routing (RFC 2328, RFC 5340 with LSA types, area types, DR/BDR), BGP Fundamentals for Services (RFC 4271, RFC 4760, RFC 4456), MPLS (RFC 3031, LDP, RSVP-TE, FRR), and Services Architecture (Nokia service model, SAP, SDP, pseudowire, VPLS, VPRN, IES, Epipe). This composite is an alternative to taking the four individual exams separately for Nokia NRS II certification and is valid for three years.

Sample Nokia NRS II Composite (OSPF) Practice Questions

Try these sample questions to test your Nokia NRS II Composite (OSPF) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the default OSPF hello interval on a broadcast network in Nokia SR OS?

A.10 seconds

B.30 seconds

C.5 seconds

D.20 seconds

Explanation: On broadcast network types in OSPF, the default hello interval is 10 seconds. This applies to Nokia SR OS as defined in RFC 2328.

2Which LSA type is used by an OSPF ABR to advertise summarized routes from one area into another area?

A.Type 3 Summary LSA

B.Type 4 ASBR Summary LSA

C.Type 5 AS External LSA

D.Type 1 Router LSA

Explanation: Type 3 Summary LSAs are generated by Area Border Routers (ABRs) to advertise network summaries (inter-area routes) from one OSPF area into another area.

3What is the OSPF dead interval if the hello interval is set to 10 seconds on a broadcast network?

A.40 seconds

B.30 seconds

C.20 seconds

D.10 seconds

Explanation: By default, the OSPF dead interval is 4 times the hello interval. With a hello interval of 10 seconds, the dead interval becomes 40 seconds.

4Which OSPF area type blocks Type 3, Type 4, and Type 5 LSAs while still allowing a default route?

A.Totally Stubby Area

B.Stub Area

C.Not-So-Stubby Area (NSSA)

D.Backbone Area

Explanation: A Totally Stubby Area blocks all Type 3 Summary LSAs, Type 4 ASBR Summary LSAs, and Type 5 External LSAs. The ABR injects only a Type 3 default route (0.0.0.0/0) into the area.

5In OSPF, what is the purpose of the DR (Designated Router) on a broadcast network?

A.To reduce the number of adjacencies required on multi-access networks

B.To act as the default gateway for all routers in the area

C.To originate Type 5 LSAs on behalf of all routers

D.To authenticate OSPF packets on the segment

Explanation: The Designated Router (DR) reduces the number of OSPF adjacencies on multi-access networks. Instead of each router forming adjacencies with every other router (n(n-1)/2 adjacencies), all routers form adjacencies only with the DR and BDR (2n-1 adjacencies).

6Which OSPF LSA type is generated by the DR and lists all attached routers on a broadcast segment?

A.Type 2 Network LSA

B.Type 1 Router LSA

C.Type 3 Summary LSA

D.Type 5 AS External LSA

Explanation: Type 2 Network LSAs are generated by the Designated Router (DR) for each multi-access segment. They list all routers attached to that segment and are flooded throughout the OSPF area.

7What OSPF adjacency state indicates that two routers have fully synchronized their link-state databases?

A.Full

B.2-Way

C.Exchange

D.Loading

Explanation: The Full state indicates that OSPF routers have fully synchronized their link-state databases and the adjacency is complete. This is the normal steady-state for adjacent neighbors.

8Which OSPF packet type is used to establish and maintain neighbor relationships?

A.Hello packet

B.Database Description packet

C.Link State Request packet

D.Link State Update packet

Explanation: OSPF Hello packets (Type 1) are used to discover, establish, and maintain neighbor relationships. They are sent periodically to the AllSPFRouters multicast address (224.0.0.5).

9What is the OSPF Router ID (RID) used for in an OSPF domain?

A.To uniquely identify each OSPF router in the domain

B.To determine the OSPF area a router belongs to

C.To encrypt OSPF neighbor communications

D.To assign IP addresses to OSPF interfaces

Explanation: The OSPF Router ID (RID) is a 32-bit number that uniquely identifies each OSPF router within the domain. It is used in LSA origination, DR/BDR election, and neighbor identification. It is typically configured manually or derived from the highest loopback IP address.

10In DR/BDR election, which router becomes the DR on a broadcast segment?

A.The router with the highest OSPF priority (or highest Router ID if priorities are equal)

B.The router with the lowest OSPF priority

C.The router with the lowest Router ID

D.The first router to boot on the segment

Explanation: DR/BDR election is based first on OSPF interface priority (default 1, range 0-255). The router with the highest priority becomes the DR. If priorities are equal, the router with the highest Router ID wins. A priority of 0 prevents a router from becoming DR or BDR.

About the Nokia NRS II Composite (OSPF) Exam

The Nokia 4A0-C04 NRS II Composite Exam (OSPF version) is a comprehensive Service Routing Certification (SRC) test that combines four individual exams into one: OSPF routing (4A0-113), BGP Fundamentals for Services (4A0-114), MPLS (4A0-103), and Services Architecture (4A0-104). It validates advanced knowledge of service-provider routing protocols, MPLS transport, and Nokia service architecture on the 7750 SR running SR OS. Passing this single composite exam earns the Nokia NRS II certification as an alternative to taking the four individual exams separately.

Assessment

Nokia NRS II Composite (OSPF) Study Tips from Top Performers

1The composite exam covers four domains equally - do not neglect any single area. A weakness in Services Architecture can offset strong OSPF and MPLS knowledge.

2Create a study schedule that rotates through all four domains weekly rather than studying them sequentially - retention across all areas matters for one exam sitting.

3Know all OSPF LSA types and their flooding scopes: Type 1/2 (area-local), Type 3/4 (area border), Type 5 (domain-wide), Type 7 (NSSA area-local with translation to Type 5).

4Master OSPF area type restrictions: stub areas block Type 5, totally stubby blocks Type 3/4/5, NSSA replaces Type 5 with Type 7, and no area can be both backbone and stub.

5Know the Nokia service model hierarchy cold: Customer > Service > SAP/SDP > Pseudowire - Services Architecture questions test this structure extensively.

6Practice time management: 70 questions in 120 minutes means approximately 1.7 minutes per question. Flag difficult questions and return to them rather than spending too long on any single item.

7Use show commands for each domain in your lab: show router ospf neighbor/database/lsa, show router bgp summary/routes vpn-ipv4, show router mpls lsp/forwarding, and show service id/base/all for services.

Frequently Asked Questions

What is on the Nokia 4A0-C04 NRS II Composite exam?

The Nokia 4A0-C04 combines four individual exams into one: OSPF routing (4A0-113) covering RFC 2328 and RFC 5340 with LSA types and area types, BGP Fundamentals for Services (4A0-114) covering RFC 4271, RFC 4760, and RFC 4456, MPLS (4A0-103) covering RFC 3031, LDP, RSVP-TE, and FRR, and Services Architecture (4A0-104) covering the Nokia service model with SAP, SDP, pseudowire, and service types (VPLS, VPRN, IES, Epipe). It is an alternative to taking the four exams separately for NRS II certification.

How long is the Nokia NRS II Composite OSPF exam and how many questions does it have?

The 4A0-C04 exam contains 70 multiple-choice questions with a 120-minute time limit. At roughly 1.7 minutes per question, time management across all four domains is critical.

What is the passing score for Nokia 4A0-C04?

Nokia requires a 70% score (49 of 70 correct) to pass the NRS II Composite OSPF exam. Aim for 85% or higher in practice exams - the breadth of four domains in one exam means weaknesses in any single area can impact your overall score.

How much does the Nokia 4A0-C04 exam cost?

The 4A0-C04 exam fee is $375 USD per attempt, paid to Pearson VUE at registration. This composite exam is more expensive per attempt than individual exams but costs less than taking all four separate exams ($125 each = $500 total).

What is the difference between 4A0-C03 and 4A0-C04?

Both are NRS II Composite exams with identical structure covering BGP Fundamentals, MPLS, and Services Architecture. The difference is the IGP section: 4A0-C03 uses IS-IS routing (4A0-112) while 4A0-C04 uses OSPF routing (4A0-113). Choose the version matching your primary IGP experience.

Where do I take the Nokia NRS II Composite OSPF exam?

The 4A0-C04 exam is delivered by Pearson VUE either at a Pearson VUE test center or via OnVUE online proctoring, where available. Schedule through pearsonvue.com/us/en/nokia.html with your Nokia candidate profile.
