  B. Incorrect subnet mask
  C. System interface not included in OSPF
  D. Area ID not the same
  E. Different metric set on each end of the link
  F. Router ID not defined
  A. MTU mismatch
  B. Incorrect subnet mask

  A. Challenge handshake authentication protocol (CHAP)
  B. Two factor authentication
  C. MD5 authentication
  D. Extensible authentication protocol (EAP)

  Router R2 learns the networks shown from IS-IS. Router R2 is configured to redistribute routes from IS-IS to OSPF as shown. Assume the OSPF and IS-IS adjacencies are operational.

  How many OSPF Type 5 LSAs will router R1 receive from router R2?

  B. 1
  C. 2
  D. 3
  E. 4
  D. 3

• Question 204:

  What is the primary purpose of classless interdomain routing (CIDR)?

  A. To support classful routing protocols.
  B. To allow IP routes to be defined using any number of bits for the network portion of the address.
  C. To allow interdomain routing between an IGP and EGP such as OSPF and BGP.
  D. To simplify the allocation of IP address space by defining a fixed size for the network portion of the address for each of the address classes.
  B. To allow IP routes to be defined using any number of bits for the network portion of the address.

• Question 205:

  How is the DR selected when an OSPF router is added to a broadcast network?

  A. The current DR is selected, if there is one. Otherwise, the router with the lowest priority is the DR. If priorities are the same, the DR is chosen based on the lowest RID.
  B. The current DR is selected, if there is one. Otherwise, the router with the highest priority is the DR. If priorities are the same, the DR is chosen based on the highest RID.
  C. The router with the lowest priority is the DR. If priorities are the same, the current DR is selected. Otherwise the DR is chosen based on the lowest RID.
  D. The router with the highest priority is the DR. If priorities are the same, the current DR is selected. Otherwise the DR is chosen based on the highest RID.
  B. The current DR is selected, if there is one. Otherwise, the router with the highest priority is the DR. If priorities are the same, the DR is chosen based on the highest RID.

• Question 206:

  Two IS-IS L1/L2 routers are in the same area on the same Ethernet segment. One of the routers is the DIS. How many adjacencies will be formed between them?

  A. None
  B. 1
  C. 2
  D. 3
  E. 4
  C. 2

• Question 207:

  Identify two attributes of Distance Vector Protocols: (Choose two)

  A. Use split horizon by default.
  B. Send information about directly connected links to neighbors at periodic intervals.
  C. Use holddown timers when topologies change to allow for convergence.
  D. Maintain multiple databases: neighbor, topology and routing.
  A. Use split horizon by default.
  C. Use holddown timers when topologies change to allow for convergence.

• Question 208:

  What modes of authentication are supported for RIPv2 on the Alcatel-Lucent 7750 SR?

  A. RIPv2 supports basic and MD5 authentication only.
  B. RIPv2 supports password and MD5 authentication only.
  C. RIPv2 does not support authentication, password and MD5 authentication.
  D. RIPv2 does not support authentication.
  C. RIPv2 does not support authentication, password and MD5 authentication.

• Question 209:

  Router R1 learns the network 192.168.3.0/24 from IS-IS. Given the OSPF configuration shown, why isn't the 192.168.3.0/24 route in router R3's route table?

  A. The route policy should be applied as an import policy.
  B. The route policy should say "from protocol isis" instead of "from protocol direct".
  C. The ASBR configuration should be removed.
  D. The interface between routers R1 and R3 must be in OSPF area 0.
  B. The route policy should say "from protocol isis" instead of "from protocol direct".

• Question 210:

  What is wrong with the following filter configuration from an Alcatel-Lucent 7750 SR?

  RTR-B# configure filter RTR-B>config>filter# ip-filter 1 create RTR-B>config>filter>ip-filter$ entry 1 create RTR-B>config>filter>ip-filter>entry$ match src-ip 172.2.0.0/16 RTR-B>config>filter>ip-filter>entry# action drop RTR-B# configure router interface toRTR-A RTR-B>config>router>if# egress RTR-B>config>router>if>egress# filter ip 1

  A. There is nothing wrong with this filter
  B. The filter should be applied to the ingress and not the egress.
  C. The mask cannot be a "/" value, it must be in dotted decimal.
  D. All traffic is being blocked
  D. All traffic is being blocked
