CCNA – Basic Questions
Here you will find answers to CCNA – Basic Questions
Question 1
For which type of connection should a straight-through cable be used?
A. switch to switch
B. switch to hub
C. switch to router
D. hub to hub
E. router to PC
Answer: C
Explanation
To specify when we use crossover cable or straight-through cable, we should remember:
Group 1: Router, Host, Server
Group 2: Hub, Switch
One device in group 1 + One device in group 2: use straight-through cable
Two devices in the same group: use crossover cable
In this case we can use straight-through cable to connect a switch to a router -> C is correct.
Question 2
Which type of cable is used to connect the COM port of a host to the COM port of a router or switch?
A. crossover
B. straight-through
C. rolled
D. shielded twisted-pair
Answer: C
Explanation
The correct question should be “Which type of cable is used to connect the COM port of a host to the CONSOLE port of a router or switch?” and the correct answer is rollover cable. But we can’t plug this rollover cable directly into our host because it will not work. We often use a RJ45 to DB9 Female cable converter as shown below:
Question 3
What is the first 24 bits in a MAC address called?
A. NIC
B. BIA
C. OUI
D. VAI
Answer: C
Explanation
Organizational Unique Identifier (OUI) is the first 24 bits of a MAC address for a network device, which indicates the specific vendor for that device as assigned by the Institute of Electrical and Electronics Engineers, Incorporated (IEEE). This identifier uniquely identifies a vendor, manufacturer, or an organization.
Question 4
In an Ethernet network, under what two scenarios can devices transmit? (Choose two)
A. when they receive a special token
B. when there is a carrier
C. when they detect no other devices are sending
D. when the medium is idle
E. when the server grants access
Answer: C D
Explanation
Ethernet network is a shared environment so all devices have the right to access to the medium. If more than one device transmits simultaneously, the signals collide and can not reach the destination.
If a device detects another device is sending, it will wait for a specified amount of time before attempting to transmit.
When there is no traffic detected, a device will transmit its message. While this transmission is occurring, the device continues to listen for traffic or collisions on the LAN. After the message is sent, the device returns to its default listening mode.
So we can see C and D are the correct answers. But in fact “answer C – when they detect no other devices are sending” and “when the medium is idle” are nearly the same.
Question 5
Which two benefits are provided by using a hierarchical addressing network addressing scheme? (Choose two)
A. reduces routing table entries
B. auto-negotiation of media rates
C. efficient utilization of MAC addresses
D. dedicated communications between devices
E. ease of management and troubleshooting
Answer: A E
Question 6
When a host transmits data across a network to another host, which process does the data go through?
A. standardization
B. conversion
C. encapsulation
D. synchronization
Answer: C
Explanation
To transmit to another host, a host must go through the TCP/IP model (very similar to the OSI model). At each layer, the message is encapsulated with that layer’s header (and trailer if it has). This process is called encapsulation.
Question 7
Which two Ethernet fiber-optic modes support distances of greater than 550 meters?
A. 1000BASE-CX
B. 100BASE-FX
C. 1000BASE-LX
D. 1000BASE-SX
E. 1000BASE-ZX
Answer: C E
Explanation
Below lists the cabling standards mentioned above
| Standard | Cabling | Maximum length |
| 1000BASE-CX | Twinaxial cabling | 25 meters |
| 100BASE-FX | Two strands, multimode | 400 m |
| 1000BASE-LX | Long-wavelength laser, MM orSM fiber | 10 km (SM)3 km (MM) |
| 1000BASE-SX | Short-wavelength laser, MM fiber | 220 m with 62.5-micron fiber; 550 mwith 50-micron fiber |
| 1000BASE-ZX | Extended wavelength, SM fiber | 100 km |
Note:
+ MM: Multimode
+ SM: Single-mode
(Reference: The official self-study test preparation guide to the Cisco CCNA INTRO exam 640-821)
Question 8
Refer to the exhibit. What type of connection would be supported by the cable diagram shown?
| Pin | Color | Function | Pin | Color | Function |
| 1 | White/Green | TX+ | 1 | White/Green | TX+ |
| 2 | Green | TX- | 2 | Green | TX- |
| 3 | White/Orange | RX+ | 3 | White/Orange | RX+ |
| 6 | Orange | RX- | 6 | Orange | RX- |
A. PC to router
B. PC to switch
C. server to router
D. router to router
Answer: B
Explanation
From the “Pin” and “Color” in the exhibit we know that this is a straight-through cable so it can be used to connect PC to switch.
Question 9
Refer to the exhibit. What type of connection would be supported by the cable diagram shown?
| Pin | Color | Function | Pin | Color | Function |
| 1 | White/Green | TX+ | 3 | White/Green | RX+ |
| 2 | Green | TX- | 6 | Green | RX- |
| 3 | White/Orange | RX+ | 1 | White/Orange | TX+ |
| 6 | Orange | RX- | 2 | Orange | TX- |
A. PC to router
B. PC to switch
C. server to switch
D. switch to router
Answer: A
Explanation
This is a crossover cable so it can be used to connect PC and router.
Question 10
Which two topologies are using the correct type of twisted-pair cables? (Choose two)
A. 
B. 
C. 
D. 
E. 
Answer: D E

Just a friendly advise from experienced but jobless network engineer. It’s good if you have Cisco knowledge because this is the foundation of all networking knowledge but do not focus on this. There are millions of CCIEs and CCNPs in the world and there are billions of CCNA passers(i’m exaggerating but I can say there’s really a LOT!) If you want to be a network engineer focus on other brands which has few certified candidates.
I have 5.4 years of experience in networks but after quitting my job, I am jobless for almost 6 months already. I quit because I focus on my CCIE and guess what? I’ve found out that there’s a lot of CCNP and CCIE passers from fortune 500 companies. It’s already OVERCROWDED. Out of 20 applications I only got 4 calls for interview. Passed the technical interviews got 2 offers but offers are not really that high if you’re going to base it on my previous salary. Because of huge number of applicants, companies tend to lower down their salary offers for they have other options (many applicants to choose from). Most of huge companies only looks for 3 to 5 network engineers to be hired. Some companies tend to do mass hiring but it is almost like a call center job and no hard core troubleshooting you’ve always dreamed of.
I’ve learned my mistakes, quitting my job for the sake of studying the highest level of routing and switching in CISCO and learning that I’m not the only CCIE passers in our city.
You are jobless by choice so !

Paul: If you have studied either 9tut or spike dumps you will 100% pass.
For people taking the test, make sure you practice the labs, but be prepared for little things to change like Host C in the ACL labs & eigrp the as numbers are different.
