It's Saturday, August 16, and here are the answers to yesterday's Cisco training questions!
I'll have another set of questions on the blog later today, and in the meantime you can take these CCNA, CCENT, and CCNA Security practice exams over on the main site!
CCNA Certification And CCENT Certification:
Name a common use for each of the following cable types (Answers listed next to cable type)
Straightthrough - One use is connecting a switch port to a transceiver, which would then be attached to a router's AUI port.
Crossover - A common use is to connect two switches with a crossover cable, allowing a trunk to be formed.
Rollover - A very common use is to connect a laptop or PC to a Cisco router or switch's console port.
CCNA Security Certification / CCNP ISCW Exam:
The following three timers sound a great deal alike, but they have very different functions. What purpose do each of these timers fill?
ip inspect finwait-time
ip inspect tcp synwait-time
ip inspect tcp idle-time
Answers:
ip inspect finwait-time defines the amount of time between one of the two endpoints of an established TCP session starts to end the connection and the time that entry is removed from the state table. Default is 5 seconds.
ip inspect tcp idle-time defines just what you think it would - the amount of time an idle TCP connection is kept in the state table. Default is 3600 seconds.
ip inspect tcp synwait-time defines the time allowed for a TCP three-way handshake to reach the Established stage. Default is 30 seconds. If this timer expires, the connection is terminated and the entry removed from the router's state table.
CCNP Certification / BSCI Exam:
What is the private range of BGP AS numbers?
BGP allows you quite a bit of range when it comes to selecting an AS number:
R1(config)#router bgp ?
<1-65535> Autonomous system number
Just as there are private IP addresses, there are private AS numbers. The AS numbers 64512 - 65535 are considered "private" AS numbers and just as private IP addresses should not be advertised to external networks, neither should private AS numbers.
Public or private, you can't assign AS number zero with BGP, just as you couldn't with EIGRP and IGRP.
CCNP Certification / BCMSN Exam:
Name a router redundancy protocol that does *not* use the concept of a "virtual router".
Answer: The ICMP Router Discovery Protocol (IRDP) fits this description. Other, more common router redundancy protocols use virtual routers.
CCNP / ONT Exam: (My ONT Study Package will be released this upcoming Monday!)
What command resulted in the following output?
R1# ?
Serial0/1/0
AutoQoS Discovery enabled for applications
Discovery up time: 4 minutes, 29 seconds
Answer: show auto discovery qos.
See you later today with more questions!
To your success,
