Free Nokia NRS II Composite: OSPF version Exam 4A0-C04 Exam Practice Test

Which of the following statements regarding BGP shortcuts is FALSE?

• MPLS tunnels are used to carry transit traffic across the network.
  
• A full mesh of iBGP peering sessions is not required,
  
• Edge and transit routers need to be configured with BGP.
  
• The transit routers need to support LDP or RSVP-TE LSPs.
  

Which of the following about the Isp-ping command on the Nokia 7750 SR is FALSE?

• An echo request is sent based on the LSP's label stack.
  
• Echo reply packets may not take the same path as the LSP.
  
• The IP destination address is used to initiate echo requests,
  
• The test fails if the LSP is not operationally up.
  

An IS-IS TE enabled router has an interface on a 500Mbps link and it is configured with a 25% subscription. If this interface is not used by any LSPs. what value will be shown in the Reservable Bandwidth sub-TLV?

• 125 Mbps
  
• 500 Mbps
  
• 625 Mbps
  
• 2000 Mbps
  

Which of the following about RSVP-TE is FALSE?

• It supports traffic protection using IGP equal cost paths.
  
• It supports CAC to prevent resource overbooking.
  
• It supports LSPs with traffic engineering constraints.
  
• It supports LSPs that follow the IGP best path.
  

Which of the following is NOT a characteristic of MPLS?

• It provides the ability to establish connection oriented paths over a connectionless IP network.
  
• It provides a mechanism to engineer network traffic patterns independently of IP routing tables.
  
• It will work over most physical layer protocols.
  
• It can use GRE tunnels to transport data from many different protocols over an IP network.
  

Which of the following defines an FEC in traditional IP?

• A group of packets that will be forwarded by the router in the same manner, over the same path.
  
• A group of packets that arrive at the router on the same interface,
  
• A group of packets that leave the router on the same interface.
  
• A group of packets that arrive at the router on the same interface, from the same source.
  

In a Layer 2 encapsulation using T-LDP, what does the first (top) label represent?

• Tunnel Label
  
• VC Label
  
• Operational Control Word
  
• UNI
  
• NNI
  

What is the protocol number for OSPF in the IP header?

• OSPF uses TCP, so the protocol number is 6.
  
• OSPF uses UDP, so the protocol number is 17.
  
• OSPF does not use IP.
  
• OSPF has its own protocol number of 89.
  

What is the default priority value used for electing the DR on an Nokia 7750 SR running OSPF on an Ethernet?

• Priority of 0
  
• Priority of 1
  
• Priority of 64
  
• Priority of 255
  

Which of the following about LSP path configuration on an Nokia 7750 SR is TRUE?

• The path must include at least one hop.
  
• The path may be used for multiple LSPs.
  
• The path may be used multiple times in a single LSP.
  
• The path must define a tunnel destination IP address.
