CCNA – Operations 3
Here you will find answers to Operations Questions – Part 3
Question 1:
Your company wants to reconfigure a Catalyst 2950. which actions must be taken to erase the old configuration? (Choose three)
A – Erase flash
B – Restart the switch
C – Delete the VLAN database
D – Erase the startup configuration
Answer: B C D
Question 2:
If the subnet mask is 255.255.255.224, which of the following addresses can be assigned to network hosts? (Choose three)
A – 15.234.118.63
B – 92.11.178.93
C – 134.178.18.56
D – 192.168.16.87
Answer: B C D
Explanation:
The addresses can be assigned to network hosts are the addresses that satisfy these conditions:
+ They don’t belong to network addresses
+ They don’t belong to broadcast addresses
The last octet of the subnet mask is 224, which is 1110 0000 in binary form, so the increment is 32. This is the value we need to find out the network addresses and broadcast addresses when using the 255.255.255.224 subnet mask.
Network addresses: x.x.x.0, x.x.x.32,x.x.x.64,x.x.x.96,x.x.x.128,x.x.x.160,x.x.x.192,x.x.x.224
Broadcast addresses: x.x.x.31, x.x.x.63, x.x.x.95, x.x.x.127, x.x.x.159, x.x.x.191, x.x.x.223
(Notice we don’t care about the first three octets because the first three octets of the subnet mask are all 255)
From that we learn 15.234.118.63 is one of the broadcast addresses. Other answers are correct because they are neither network addresses nor broadcast addresses.
Question 3:
An administrator issues the command “ping 127.0.0.1″ from the command line prompt on a PC host named PC1. If an ICMP reply is received, what does this confirm?
A – The PC host PC1 has connectivity with a local host
B – The PC host PC1 has connectivity with a Layer 3 device
C – The PC host PC1 has a default gateway correctly configured
D – The PC host PC1 has connectivity up to Layer 5 of the OSI model
E – The PC host PC1 has the TCP/IP protocol stack correctly installed
Answer: E
Explanation:
If you are having problems with your network then issue the command “ping 127.0.0.1″ to prove the network card and the TCP/IP software is working correctly. Address 127.0.0.1 is reserved for the test loop back purpose.
Question 4:
Study the exhibit carefully, can you tell which three description are correct about the ways used by the router R1 to choose a path to the 10.1.3.0/24 network when different routing protocols are deployed? (Choose three)
A – When RIPv2 is the routing protocol, only the path R1-R4 is to be installed into the routing table by default
B – When RIPv2 is the routing protocol, the equal cost paths R1-R3-R4 and R1-R2-R4 are to be installed in the routing table
C – If both EIGRP and OSPF are working on the network with their default configurations, the EIGRP paths will be installed in the routing table
D – By default, if EIGRP is the routing protocol, the equal cost paths R1-R3-R4 and R1-R2-R4 will be installed in the routing table
Answer: A C D
Explanation:
RIP is a distance vector routing protocol and it uses hop count as the metric for path selection so only the path R1-R4 (with only 2 hops) will be installed into the routing table.
If both EIGRP and OSPF are used, the EIGRP paths will be installed in the routing table because the default administrative distance of EIGRP is 90 while that of OSPF is 110. Therefore these routers will choose EIGRP because it has lower administrative distance value (Notice that a lower value for the administrative distance indicates the more reliable route).
Question 5:
Which two statements describe characteristics of IPv6 unicast addressing? (Choose two)
A. Global addresses start with 2000::/3
B. Link-local addresses start with FE00:/12
C. Link-local addresses start with FF00::/10
D. There is only one loopback address and it is ::1
E. If a global address is assigned to an interface, then that is the only allowable address for the interface.
Answer: A D
Explanation:
Below is the list of common kinds of IPv6 addresses:
| Loopback address | ::1 |
| Link-local address | FE80::/10 |
| Site-local address | FEC0::/10 |
| Global address | 2000::/3 |
| Multicast address | FF00::/8 |
From the above table, we learn that A and D are correct while B and C are incorrect. Notice that the IPv6 unicast loopback address is equivalent to the IPv4 loopback address, 127.0.0.1. The IPv6 loopback address is 0:0:0:0:0:0:0:1, or ::1.
E is not correct because of anycast addresses which are indistinguishable from normal unicast addresses. You can think of anycast addresses like this: “send it to nearest one which have this address”. An anycast address can be assigned to many interfaces and the first interface receives the packet destined for this anycast address will proceed the packet. A benefit of anycast addressing is the capability to share load to multiple hosts. An example of this benefit is if you are a Television provider with multiple servers and you want your users to use the nearest server to them then you can use anycast addressing for your servers. When the user initiates a connection to the anycast address, the packet will be routed to the nearest server (the user does not have to specify which server they want to use).
Apart from my recent comments in other sections I would like to thank 9tut for this site, its a very valuable resource and I will make a contribution once I recert my CCNA, hopefully next month.
Q1 was in my exam today..
Hi all, I am taking CCNA 640-802 exam first time on 30/05/2012. Could anyone please send me latest dumps which are valid for UK? My e-mail address is puneet_gill84@yahoo.co.uk. Many thanks.
@9tut
Q5
Site-local address FEC0::/10
I think its FD00::/8
FC00::/7 – 1111:1100:x:x:x:x:x:x but the last bit of the 2nd octet must be 1 since 0 is for future use, therefore from FC00::/7 it is now FD00::/8 >>>>> from jeremy ciora of CBT NUGGETS CCNA tutorial
thanks :-)
I PASSED CCNA EXAM TODAY THANKS TO ALL MIGHTY ALLAH

I did it!!..907..q1 on exam….if you want to pass CCNA…go over EVERY question on 9tut…study and u will succeed!!
Just cleared my exam with a perfect perfomance (1000/1000)…..GRATITUDES: First and foremost to the almighty God for everythng he has been since i started preparing for this exam abt a year ago! the Todd lamlle (6th edition), this book gave me the foundation i needed and i consider myself one of the fastest subnetting geek thanks to Todd’s chapter on subnetting…then seriously, who wud forget this guy (9tut) thanks alot man,i finished my exam 40 minutes before time thanks to the speed you gave me in simulations…examcollection, thanks alot guys i ddint see any qn that i hadnt met in the dumps before, then the CBT nuggets videos….they cleared (enhanced) all of the concepts i have learned from all of the materials i have already mentioned! thank you all so much…..i will DONATE when i get my credit card! keep the good work going 9tut
ABOUT MY EXAM:
I had total of 50 questions….
Had three simulations….ACL2, same as here at 9tut but modified as the third table of modifications above and i was dealing with host B plus different IP addresses, EIGRP almost the same as here, had to change the AS in router Home 2 from somethng 21 to 221 and add the appropriate networks also i had to delete and add some networks from router Home 1 (central router) and finaly the VTP…same as here just different question to follow the same procedures in resolving
NB: i ddnt see anythng that i had not come across before
for any other enquiries find me at ropamson@gmail.com …..best of luck for everybody working on CCNA

Thanks 9tut. I made it. I passed my CCNA 200-120 today. The sim is Access-list 1 , Access-list 2 & EIGRP. A lot of new questions like Netflow, Syslog, SNMP, VRRP, and GLBP.
Is there anyone buy the voucher from Adeel ? It is reqlly weird that he did not reply my email. Can he be trusted ? I afraid after I sent the money he would not provide the voucher. I need ur advice. Pls email me at supportpc84@hotmail.com. Thanks.
Can anyone tell me the question 1, why delete the vlan database will clear the old configuration for switch ?
@@@@Mike
Always buy vouchers fron authorised and trustworthy sources to avoid any unforeseen issues.
Regarding the Que pertaing to vlan….deleting the previos Vlan will avoid any configuratinal issues araining in the future….After all the switch has to match the VTP domain name!
