Q1. DRAG DROP - (Topic 7)

A user is unable to connect to the Internet. Based on the layered approach to troubleshooting and beginning with the lowest layer, drag each procedure on the left to its proper category on the right.

Answer:

Explanation:

The question asks us to “begin with the lowest layer” so we have to begin with Layer 1: verify physical connection; in this case an Ethernet cable connection. For your information, “verify Ethernet cable connection” means that we check if the type of connection (crossover, straight-through, rollover…) is correct, the RJ45 headers are plugged in, the signal on the cable is acceptable…

Next we “verify NIC operation”. We do this by simply making a ping to the loopback interface 127.0.0.1. If it works then the NIC card (layer 1, 2) and TCP/IP stack (layer 3) are working properly.

Verify IP configuration belongs to layer 3. For example, checking if the IP can be assignable for host, the PC’s IP is in the same network with the gateway…

Verifying the URL by typing in your browser some popular websites like google.com, microsoft.com to assure that the far end server is not down (it sometimes make we think we can’t access to the Internet). We are using a URL so this step belongs to layer 7 of the OSI model.

Q2.  - (Topic 8)

Which command can you enter to determine whether serial interface 0/2/0 has been configured using HDLC encapsulation?

A. router#show platform

B. router#show interfaces Serial 0/2/0

C. router#show ip interface s0/2/0

D. router#show ip interface brief

Answer: C

Q3.  - (Topic 5)

You are working in a data center environment and are assigned the address range 10.188.31.0/23. You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts each. Which IP address range meets these requirements?

A. 10.188.31.0/26 

B. 10.188.31.0/25 

C. 10.188.31.0/28 

D. 10.188.31.0/27 

E. 10.188.31.0/29

Answer: D

Explanation:

Each subnet has 30 hosts < 32 = 25 so we need a subnet mask which has at least 5 bit 0s

-> /27. Also the question requires the maximum number of subnets (which minimum the number of hosts-per-subnet) so /27 is the best choice.

Q4.  - (Topic 8)

Which type of device can be replaced by the use of subinterfaces for VLAN routing?

A. Layer 2 bridge

B. Layer 2 switch

C. Layer 3 switch

D. router

Answer: C

Q5.  - (Topic 8)

What are three broadband wireless technologies? (Choose three.)

A. WiMax

B. satellite Internet

C. municipal Wi-Fi

D. site-to-site VPN

E. DSLAM

F. CMTS

Answer: A,B,C

Q6.  - (Topic 5)

Refer to the exhibit.

Which address range efficiently summarizes the routing table of the addresses for router Main?

A. 172.16.0.0./21

B. 172.16.0.0./20

C. 172.16.0.0./16

D. 172.16.0.0/18

Answer: B

Explanation:

The 172.16.0.0./20 network is the best option as it includes all networks from 172.16.0.0 –

172.16.16.0 and does it more efficiently than the /16 and /18 subnets. The /21 subnet will not include all the other subnets in this one single summarized address.

Q7.  - (Topic 8)

Which command can you use to set the hostname on a switch?

A. switch-mdf-c1(config)#hostname switch-mdf1

B. switch-mdf-c1>hostname switch-mdf1

C. switch-mdf-c1#hostname switch-mdf1

D. switch-mdf-c1(config-if)#hostname switch-mdf1

Answer: A

Q8.  - (Topic 3)

Refer to the exhibit.

What can be determined about the router from the console output?

A. No configuration file was found in NVRAM.

B. No configuration file was found in flash.

C. No configuration file was found in the PCMCIA card.

D. Configuration file is normal and will load in 15 seconds.

Answer: A

Explanation:

When no startup configuration file is found in NVRAM, the System Configuration Dialog will appear to ask if we want to enter the initial configuration dialog or not.

Q9.  - (Topic 5)

Which option is a valid IPv6 address?

A. 2001:0000:130F::099a::12a

B. 2002:7654:A1AD:61:81AF:CCC1

C. FEC0:ABCD:WXYZ:0067::2A4

D. 2004:1:25A4:886F::1

Answer: D

Explanation:

An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets). The groups are separated by colons (:). An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The leading 0’s in a group can be collapsed using ::, but this can only be done once in an IP address.

Q10.  - (Topic 5)

How many bits are contained in each field of an IPv6 address?

A. 24

B. 4

C. 8

D. 16

Answer: D

Explanation:

An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets). The groups are separated by colons (:). An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
