What is Nokia Services Architecture?

A structured architecture called Nokia Service Architecture was created to provide broadband, MPLS, and advanced IP services in extensive carrier and business networks. This design prioritizes service delivery above packet forwarding, allowing Internet access, Layer-3 VPNs, and VPLS to operate smoothly over the same backbone. By separating the transport and service layers, it guarantees scalability, flexibility, and a more streamlined architecture for debugging intricate systems.

The Service Router Operating System (SR OS), which drives Nokia’s high-performance routers, is at the heart of the company’s service architecture. Multiple services may coexist on the same infrastructure because of SR OS’s consistent routing, MPLS, QoS, and security technologies. Because of its multi-service flexibility, operators may run VPNs, Internet, and even mobile backhaul concurrently without sacrificing dependability or speed.

4. All of the service’s SAPs, spoke SDPs, and mesh SDPs are inundated with traffic.
5. There isn’t a lot of traffic.

 

Question 2:

When it comes to a fully meshed VPLS service with a default setup, which of the following claims is TRUE? (Pick 3)

1. The mesh-sdp’s vc-id has to be specifically set up.
2. A PE uses the service ID to automatically assign the VC-ID on the mesh-SDP.
3. All PE routers do not need to have the same VPLS service ID.
4. Every PE router has to have the same VPLS service ID.
5. In the SDP setup, all PE routers’ signaling must be set to TLDP if dynamic signaling is needed.
6. Since all PE routers’ signaling will be set to TLDP by default in the SDP setup, dynamic signaling doesn’t require any configuration changes.

 

Question 3:

Three separate Alcatel-Lucent PE routers host the websites of customer ‘A’. The routers are fully mesh-connected to one another over an IP/MPLS network. Consumer ‘A’ needs a

VPLS service. Out of the following claims, which is true? (Pick 2)

2. Two VPLS services are needed for every router.
3. One SDP and two LSPs are needed for each router, one for each of the other two routers.
4. Two SDPs are needed for every router.
5. Three SDPs are needed for each router.

 

Question 4:

Which of these claims is accurate?

1. On an IES interface, an OSPF adjacency can be created.
2. IES enables consumers to join provider MP-BGP sessions.
3. To connect to consumer networks, an IES service has to employ static routes.
4. OSPF and IS-IS are only supported in passive mode by an IES interface.

 

Question 5:

Regarding SDP-PING, which of the following claims is TRUE? (Pick 3)

1. Offers a way to identify the hops that an SDP makes.
2. Offers unidirectional in-band connection testing.
3. Offers round-trip in-band connection testing.
4. Examines if an SDP ID’s far-end IP address may be reached inside the SDP encapsulation.
5. Gives details about the precise MTU that is supported between service termination and service entrance.

 

Question 6:

You are responsible for implementing BGP as the main routing protocol in a big service provider network so that several independent systems may exchange routes with one another. Although route reflectors are necessary for the network architecture to reduce the amount of iBGP sessions, some engineers are worried about possible routing loops and less-than-ideal routing pathways. Which of the following best sums up how route reflectors contribute to fewer iBGP sessions while preserving BGP loop prevention?

1. They recalculate routes using OSPF metrics to avoid loops.
2. To prevent reflection loops, they affix cluster IDs to updates.
3. To avoid routing loops, they need confederations.
4. To avoid loops, they use the default MED settings.

 

Question 7:

A network engineer must make sure that external routes discovered by eBGP peers are appropriately announced to iBGP neighbors inside the AS when BGP is deployed in a Nokia 7750 SR router. Some prefixes, nevertheless, are not receiving the desired level of promotion. The engineer believes the iBGP advertising guideline is being implemented after conducting an inquiry. Which of the following best describes why not all eBGP-learned routes are shared automatically within iBGP without further setup?

1. By default, only neighbors with higher MED values are advertised routes via BGP.
2. To fully advertise, BGP needs to redistribute eBGP routes into the IGP.
3. By design, iBGP does not promote routes that it has learnt from other iBGP peers.
4. Without requiring explicit configuration, route reflectors automatically fix this problem.

 

Question 8:

A distributed Epipe service is best described by which of the following?

1. An Epipe with two or more SDPs set up.
2. An Epipe with three or more SAPs set up.
3. An Epipe without SDPs set that has two SAPs on the same node
4. An Epipe connects two nodes with one SAP and one SDP setup each.

 

Question 9:

On the Nokia SR OS, you are setting up BGP to connect to many ISPs for Internet transit. While one provider allows complete Internet routing tables, another demands that your AS should only expose client prefixes. You choose to regulate outgoing ads using route policies. Which approach preserves the complete table exchange with the second provider while guaranteeing that only customer prefixes are delivered to the first provider?

1. Use community strings to filter other routes and indicate customer routes.
2. Selectively limit ads using MED characteristics.
3. Set up an AS-path prepend for routes that are not needed.
4. Use the next-hop-self property to block ads.

 

Question 10:

An engineer is employing Nokia routers to resolve BGP scalability difficulties in a service provider core network. The whole Internet routing table is using excessive memory and CPU resources. To maximize resources, the group takes into account default routing and route aggregation. Which of the following approaches, without taxing router resources, strikes the optimum balance between scalability and routing flexibility

1. Disable BGP sessions by configuring only static routes.
2. When implementing aggregation upstream, use the customer edge routers’ default routes.
3. Turn off route reflection and provide a direct announcement about filled tables.
4. To maximize routing scalability, only use MED.
