Point-to-Multipoint

Unicast

The Alcatel-Lucent 7750 SR s OSPF implementation supports which two packet exchange authentication techniques? (Choose two)

Message Digest 5 (MD5)

Internet Protocol Security (IPSec)

Plain text

Rivest, Shamir, Adleman (RSA)

List the true statements with regards to the OSPF Hello protocol. (Choose two)

OSPF Hello protocol provides dynamic neighbor discovery

OSPF Hello protocol Hello timers do not need to match between neighbors

OSPF Hello protocol is used as a keep-alive to maintain neighbor adjacency

OSPF Hello protocol is used to negotiate parameters to maintain neighbor relationships

OSPF Hello protocol is used to exchange routing updates

In what OSPF area type will one see Type 7 LSAs

Not So Stubby Area (NSSA)

Stub Area

Backbone Area

Normal Area

OSPF Router A has interfaces in Area 0, Area 1, and Area 3. OSPF Router B has interfaces in Area 0 and Area 4. OSPF Router C has interfaces in Area 0 and Area 5. For which OSPF areas will Router A maintain a link state database? (Choose all that apply)

OSPF Area 0

OSPF Area 1

OSPF Area 3

OSPF Area 4

OSPF Area 5

What of the following statements are true? (Choose two)

OSPF Area 0 is a Normal area

Routers in a Normal OSPF area will not have External LSAs in their LSA databases

A router inside a Normal OSPF area may have Router, Network, and External LSAs in its LSA database

Routers in a Normal area cannot propagate External LSAs

What LSA types will be advertised by an ASBR router for external routes?

LSA Type 1

LSA Type 4

LSA Type 3

LSA Type 5

Which OSPF LSA type is used to summarize networks from one area to another?

LSA Type 1

LSA Type 2

LSA Type 3

LSA Type 4

A router (called Router A) belongs to OSPF Area 0 and OSPF Area 2. Area 2 is a Normal Area. There is an Autonomous System Boundary Router within Area 2. From the list below, select valid LSA types that Router A will advertise into Area 0. (Choose 3)

LSA Type 0

LSA Type 3

LSA Type 4

LSA Type 5

LSA Type 7

What is the range for BGP Private AS numbers?

0-2400

0-64511

64512-65535

65000-65535

Choose two of the following reasons to implement BGP in your organization? (Choose two)

Your Organization is a transit to clients in different Autonomous systems

Your Organization has a single connection to the Internet

Your Organization has legacy routers and cannot sustain Internet traffic

Your organization needs to monitor and control traffic passing through it

How does BGP set-up an internal BGP peering session?

BGP uses I-BGP to discover a route to the internal BGP speaker and then establishes a peering session

BGP requires an IGP to discover a route to the internal BGP speaker and then uses E-BGP to establish a peering session

BGP requires an EGP to discover a route to the internal BGP speaker and then uses I-BGP to establish a peering session

BGP requires an IGP to discover a route to the internal BGP speaker and then is able to establish an I-BGP peering session

Which of the following best defines an Autonomous System, as discussed within the context of BGP?Ê

An Autonomous System is a group of OSPF routers under one administrative authority

An Autonomous System is a group of networks connected together through BGP

An Autonomous System is a group of networks and network equipment under one administrative authority

Autonomous Systems are used by a single administrative authority to separate routing domains that utilize different routing protocols

Which of the following best describes a Label Switched Path?

A bi-directional path that uses label switching technology to forward traffic to its destination

A bi-directional path that uses labels to represent the router route-table to forward traffic to its destination

A uni-directional path that uses label switching technology to forward traffic to its destination

A uni-directional path that uses labels to represent the router route-table to forward traffic to its destination

A VLL allows for point-to-multipoint connections

True

False
