Correct Answer: 0x2102
Explanation:
All Cisco routers have a default configuration register setting of
0x2102, which tells the router to load the IOS from flash memory and the configuration from NVRAM.
Correct Answer: Tells the router to look in NVRAM for the boot sequence
Explanation:
The default configuration setting of 0x2102 tells the router to look in NVRAM for the boot sequence.
Correct Answer: show version
Explanation:
The
show version command provides you with the current configuration register setting.
Correct Answer: copy flash tftp
Explanation:
To copy the IOS to a backup host, which is stored in flash memory by default, use the
copy flash tftp command.
Correct Answer: You must use the terminal monitor command.
Explanation:
To see console messages through your Telnet session, you must enter the
terminal monitor command.
Correct Answer: 1 and 4
Explanation:
The
show hosts command provides information on temporary DNS entries and permanent name-to-address mappings created using the
ip host command.
Correct Answer: 2, 4 and 5
Explanation:
Before you back up an IOS image to a laptop directly connected to a router's Ethernet port, make sure the TFTP server software is running on your laptop, that the Ethernet cable is a "crossover," and that the laptop is in the same subnet as the router's Ethernet port, and then you can use the
copy flash tftp command from your laptop.
Correct Answer: 1 and 3
Explanation:
No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology. DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-Broadcast Multi-Access (NBMA) network by default.
Correct Answer: 3, 4 and 6
Explanation:
RIPv1 and IGRP are true distance-vector routing protocols and can't do much, really-except build and maintain routing tables and use a lot of bandwidth! RIPv2, EIGRP, and OSPF build and maintain routing tables, but they also provide classless routing, which allows for VLSM, summarization, and discontiguous networking.
Correct Answer: 110
Explanation:
The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running, by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the lowest, at 90.
