Refer to the exhibits. You are verifying your OSPF implementation, and it does not seem to be
functioning properly. What can you conclude from the exhibit and the show running-configuration
command output?

A) The 172.16.x.x networks need to be connected to area 0 using virtual links.
B) The OSPF areas are not configured correctly.
C) The wildcard masks for the 10.x.x.x networks are incorrect.
D) There is not enough information to make a determination.
E) The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to 172.16.0.0/16 and data is being "black holed."

2. Which statement describes the difference between a manually configured IPv6 in IPv4 tunnel versus an automatic 6to4 tunnel?

A) An automatic 6to4 tunnel does not require dual-stack (IPv4 and IPv6) routers at the tunnel endpoints.
B) A manually configured IPv6 in IPv4 tunnel does not require dual-stack (IPv4 and IPv6) routers at the tunnel endpoints.
C) An automatic 6to4 tunnel allows multiple IPv4 destinations.

What could be the cause of this problem?

A) Mismatched interface maximum transmission unit (MTU) configuration between the R1 and R2.
B) Mismatched OSPF hello interval configuration between the R1 and R2.
C) The R2 router has not received the OSPF hello packets from the R1 router.
D) DR and BDR election errors between R1 and R2.
E) Corrupted LSAs exchanges between the R1 and R2.

5. Refer to the partial configurations in the exhibit.

What address is utilized for DR and BDR identification on Router1?

A) the configured router-id address
B) the sequential 2/0 address
C) the sequential 1/1 address
D) an arbitrarily generated internal address
