Here are the answers to Saturday's Cisco CCNA and CCNP practice questions!
CCNA:
What summary route can be used to advertise the following four routes?
10.4.0.0 /16
10.5.0.0 /16
10.6.0.0 /16
10.7.0.0 /16
To manually summarize routes, break them down into binary. Then, working from left to right, note where the routes no longer have a bit in common. The value to the left of that point is your summary, and the number of bits in common is your subnet mask.
10.4.0.0 00001010 00000100 00000000 00000000
10.5.0.0 00001010 00000101 00000000 00000000
10.6.0.0 00001010 00000110 00000000 00000000
10.7.0.0 00001010 00000111 00000000 00000000
Working from left to right, these are the common bits: 00001010 000001
The value is 10.4.0.0. There are 14 bits here, so the mask is /14 in prefix notation, or 255.252.0.0 in dotted decimal. (Watch that on exam day - they're the same mask, just different formats.)
CCNP / BSCI:
What is the default OSPF network type for a serial subinterface configured as point-to-point?
A. point-to-point
B. point-to-multipoint
C. broadcast
D. non-broadcast
Answer: If you thought this was a trick question, it wasn't. The point-to-point interface will default to an OSPF ptp network type.
CCNP / BCRAN:
What command will immediately tell you whether the SPIDs and ISDN switch type have been successfully configured?
A. show dialer
B. show isdn status
C. show isdn spids
D. show switchtype
E. show isdn statistics
Answer: B. show isdn status gives you information on layers 1 - 3, as well as SPID validity information.
CCNP / BCMSN:
When Uplinkfast is enabled, how long will it take the new root port to go from blocking to forwarding?
A. About 50 seconds.
B. About 1 - 3 seconds.
C. About 30 seconds.
D. About 20 seconds
Answer: B.
.CCNP / CIT:
You want to view only the local Windows host's ARP cache. Which of the following commands, issues on that workstation, will give you that information?
A. arp -d
B. arp - s
C. arp - g
D. arp - a
Answers: C, D. Both arp -a and arp -g do the same thing - display the arp cache.
C:\>arp -a
Interface: 192.168.1.101 --- 0x2
Internet Address Physical Address Type
192.168.1.1 00-0f-66-57-eb-8c dynamic
C:\>arp -g
Interface: 192.168.1.101 --- 0x2
Internet Address Physical Address Type
192.168.1.1 00-0f-66-57-eb-8c dynamic
