Here are the answers to Thursday morning's Cisco CCNA and CCNP practice questions!
CCNA:
As part of a password recovery procedure, the configuration register will be changed to 0x2142. What does this change cause the router to do?
A. Ignore the contents of NVRAM.
B. Erase the contents of NVRAM.
C. Erase the contents of RAM.
D. Ignore the contents of RAM.
E. Erase the existing enable password.
F. Erase both the existing enable and secret passwords.
Answer: A. That config register setting tells the router to ignore the NVRAM contents.
CCNP / BSCI:
Four routers are competing to be the OSPF DR on an Ethernet segment. The highest IP address of each router is listed below. Which router will become the DR?
R1: loopback0, 100.1.1.1 /24
R2: loopback0, 200.1.1.1 /24
R3: loopback100 , 3.3.3.3 /24
R4: loopback200, 4.4.4.4 /32
Answer: R2. The router with the highest OSPF RID will be the DR, and the highest IP address on a loopback address will be that router's RID. R2's RID will be the highest.
CCNP / BCMSN:
A VTP switch has a revision number of 5. This switch receives a VTP advertisement with a revision number of 6. What action(s) will this switch take?
A. Accept the advertisement
B. Reject the advertisement
C. Increment its revision number
D. Decrement its revision number
E. Reset its revision number to zero
Answer: A, C. Since the revision number of the ad is higher than the local switch's revision number, the ad is accepted. The local switch will then increment its own revision number.
CCNP / BCRAN:
You have configured FRTS on a physical interface. There are VCs on an interface that do not have a map class applied to it. What are the proper defaults for those VCs?
A. Adaptive Shaping: Off
B. Adaptive Shaping: On
C. Bc: 7000 bits
D. Bc: 128000 bits
E. CIR: 56000 BPS
F. CIR: 1540000 BPS
G. Tc: 125 milliseconds
H. Tc: 125 nanoseconds
I: Tc: 125 decaseconds
Answer: A, C, D, G. The defaults for VCs subject to FRTS but not expressly configured with a map class: Adaptive Shaping off, Bc 7000, CIR 56000, Tc 125 milliseconds (1/8th of a second).
CCNP / CIT:
Short answer: You're configuring router-on-a-stick with a 2600 router and a 2950 switch.
What router port must be used?
What encapsulation choices are available to the router in order for ROAS to work correctly?
Answer: The minimum acceptable port speed for ROAS is Fast Ethernet. A regular Ethernet port will not work. You'll have to use dot1q encapsulation on the router, since that's the only trunking encap type that a 2950 will run - 2950s do not run ISL.
See you later tonight with the answers to Thursday night's Cisco certification exam questions, as well as more questions - only from The Bryant Advantage!
