Demo Questions

Question 1
What are the typical RIP related issues found during troubleshooting?
  1. Interface filters 
  2. Broadcast/Multicast mismatch
  3. Area id not match with neighbor
  4. Group name not match with neighbor
  5. Hop count too high
Correct answer: ABE
Question 2
Two direct connected routers are running RIPv2, neighbors are up but there is no route in the RIP database. Review the configuration information below. What is the potential problem?  
  
  1. System interface is not added to the RIP protocol
  2. No import policy is configured
  3. No export policy is configured
  4. Split-horizon has to be disabled in RIP
  5. Message-size has to be configured with a non-zero value
Correct answer: C
Question 3
The LDP session is not down between Node-1 and Node-2. Based on the following configurations, what is the cause of the problem? 
  
  1. LDP targeted-session is enabled with no service configured
  2. OSPF adjacency is not up between Node-1 and Node-2
  3. Router id is not advertised by OSPF
  4. LDP is disabled on Node-1
  5. Traffic-engineering is not enabled on Node-2
Correct answer: C
Question 4
A SDP is created on Node-2 with the far end address set to Node-3. The SDP stays down on Node-2. Based on the following CLI output from Node 2, what is the caused of the problem? 
  
  1. No LDP link session between Node 2 and Node 4
  2. No LDP link session between Node 4 and Node 3
  3. No LDP link session between Node 1 and Node 4
  4. No LDP link session between Node 3 and Node 2
  5. None of the above
Correct answer: B
Question 5
Based on the show display below, what should be done to further trouble the LSP problem? Choose all valid actions. 
  
  1. Check all the interface filters to make sure no LDP protocol is blocked
  2. Check all management filters to make sure no RSVP-TE protocol is blocked
  3. Verify all explicit hops are reachable via IGP
  4. Make sure MPLS is enabled on all appropriate interfaces
  5. Make sure LDP is enabled on all appropriate interfaces
Correct answer: BCD
Question 6
LSP toNode3 is configured on Node1, all hops configured in the lsp path and lsp destination address are reachable via IGP. Both primary and secondary LSP paths are down with failure code equal toRoute ToDestination. What is the potential cause of this problem? 
  
  1. A loose hop has to be configured in path toNode3-loose
  2. The secondary path should not be configured as standby path
  3. No traffic engineering information is exchanged by the IGP protocol 
  4. CSPF cannot be enabled with strict hop path
  5. MPLS should not be enabled on interface toPod3
Correct answer: C
Question 7
What MPLS tunnel label(s) will be used in the data packet traveling on LSP toR4 FRR leaving from Node 3 to Node 4? 
  
  1. 131069 131068
  2. 131068 3
  3. 131069
  4. 131068
  5. No label is used in the data packet
Correct answer: A
Question 8
A LSP is configured with one primary path and one secondary path as below. What configuration is required to make the LSP non-revertive. Choose the best answer.  
  
  1. Turn off CSPF and remove all the bandwidth reservations
  2. Remove the primary path and configure both paths as secondary
  3. Under asp toRouter3? configure on-revertive
  4. It is not possible to configure the LSP as non-revertive 
  5. MPLS fast re-route has to be enabled to make it non-revertive
Correct answer: B
Question 9
A CSPF LSP with no bandwidth requirement is established from Node 1 (10.10.1.1) to Node 2 (10.10.1.2). OSPF-TE is enabled on all routers in the network. What commands can be used on Node 1 to determine if another LSP can be established to Node 2 with 400M bandwidth requirement? Choose all that apply.
  1. Show router lsp detail
  2. Show router ospf database detail
  3. Show router ospf opaque-database detail
  4. Tools perform router mpls cspf to 10.10.1.2 bandwidth 400
  5. Tools dump router mpls lspinfo
Correct answer: CD
Question 10
Which one of the following CLI can be used to view all management VPLS configured on a 7x50?
  1. Show service service-using m-vpls
  2. Show service service-using
  3. Show router vpls detail
  4. Show service id <service id> base
  5. There is no CLI command to display management VPLS
Correct answer: B
