Here are the answers to Thursday's Cisco certification exam practice questions!
CCNA Exam:
Consider the configuration below and identify the true statement.
R3(config)#router rip
R3(config-router)#network 172.12.0.0
A. The router will send RIPv1 updates and accept v1 and v2 updates.
B. The router will accept and send updates for both RIPv1 and v2.
C. The router will accept and send updates for RIPv1 only.
D. The router will accept and send updates for RIPv2 only.
Answer: A. Since the version command isn't seen in the config, the RIP default of sending V1 updates and accepting both V1 and V2 updates is in effect.
CCNP Certification / BSCI Exam:
What LSA type is generated by an ABR and describe inter-area links?
A. Type 1
B. Type 2
C. Type 3
D. Type 4
E. Type 5
F. Type 6
G. Type 7
Answer: C. Type 3 LSAs are generated by ABRs and describe inter-area routes.
CCNP Certification / BCMSN Exam:
What command puts a VTP device into Secure mode?
A. vtp password
B. vtp secure
C. vtp encrypt
D. vtp endorse
Answer: A. VTP Secure mode is a fancy way of saying that a VTP password is in effect.
CCNP Certification / ISCW Exam:
Briefly describe the purpose and operation of "NAT Traversal".
Answer: NAT Traversal prevents a potential issue when NAT is used in conjunction with Encapsulating Security Protocol's (ESP) tunnel mode. Tunnel mode encrypts the original TCP/UDP header, which means the port number is hidden from the NAT process.
NAT Traversal works around this by placing an additional UDP header onto the packet. The NAT process will use the port number in that header, and all is well!
CCNP Certification / ONT Exam:
Which of the following is NOT a type of analog connection supported by Cisco routers?
A. FXS
B. FXO
C. E&M
D. CCS
Answers: A, B, C. Cisco routers support Foreign Exchange Station (FXS), Foreign Exchange Office (FXO), and E&M. CCS is Common Channel Signaling, and that's digital, not analog.
