Published on October 28, 2019

There's still time to get your CCENT — for a little while longer at least. Remember, though, that you'll need to pass both the ICND1 and ICND2 exams for the credential to roll over into the new Cisco certification program. Time is short, but it can be done.  In a poll we conducted a while back, we found that 42 percent of IT pros who passed the ICND1 spent less than two months studying. So, if you haven't started yet, then start today.

First, take a full practice exam to gauge your knowledge in each of the exam objectives. (You get unlimited Kaplan IT practice exams with every CBT Nuggets subscription.) Don't worry if you don't feel prepared. From those results you can find your strengths and weaknesses, and you'll be able to build your study plan.

For the next few weeks, focus on the areas where you need to improve, and then review the topics you feel like you know.  After you've watched every CBT Nuggets video and exhausted every practice exam you can find. Come back here, and try just one more exam.

Good luck!

1. You are performing a Wireshark packet capture and you notice the following address in use on your system – What is this address type used for?

  1. It is used to send traffic to a group of receivers

  2. It is used to send traffic to a specific receiver

  3. It is used to send traffic to the "closest" recipient

  4. It is used to send traffic to all hosts on the network

Correct Answer: a

Explanation: The IPv4 address range of to is the multicast address range. Multicast is a communication mode in IPv4 that permits the sending of traffic to a group of systems that have "subscribed" to receive the traffic. Contrast this to a unicast transmission destined for a specific machine, or a broadcast transmission that is destined for all machines.

Domain: Network Fundamentals

2. What type of IPv6 address is used by IPv6 routing protocols as the next-hop address?

  1. Multicast

  2. Broadcast

  3. Link-local

  4. Anycast

Correct Answer: c

Explanation: IPv6 routing protocols rely on the link-local IPv6 address for the next hop. This is a distinguishing characteristic between them and their IPv4 counterparts where link-local Layer 3 addresses do not exit.

Domain: Network Fundamentals


3. What is the default native VLAN on a Cisco switch and what does this mean? (Choose two.)

  1. VLAN 0

  2. VLAN 1

  3. The VLAN is tagged with a special native VLAN tag

  4. The VLAN is not tagged

Correct Answer: b, d

Explanation: The default native VLAN is 1 on a Cisco switch. This VLAN does not receive an 802.1Q tag like other VLANs will. This ensures the frames can pass over any link in the switched infrastructure whether VLAN trunking is enabled or not.

Domain: LAN Switching Fundamentals


4. Which of the following addresses is a valid Layer 2 address?

  1. 2001:0db8:85a3:0000:0000:8a2e:0370:7334

  2. 00-50-56-C0-00-01


  4. 00-50-56-C0-00-01-34-C0

Correct Answer: b

Explanation: 00-50-56-C0-00-01 is an example of a valid Layer 2 MAC address. This address is 48 bits in length and is represented in hexadecimal notation. Note that also in the options here are two different Layer 3 addresses – an IPv6 address (2001:0db8:85a3:0000:0000:8a2e:0370:7334) and an IPv4 address (

5. What command allows you to confirm the IP address and mask assigned to an interface?

  1. show interfaces terse

  2. show addesses

  3. show ip interface brief

  4. show ip interface

Correct Answer: d

Explanation: One of the valuable features of show ip interface is the ability to confirm the network mask assigned with the IP address on the interface.

Domain: Routing Fundamentals


6. What is the routing protocol code for EIGRP on a Cisco router?

  1. E

  2. B

  3. G

  4. D

Correct Answer: d

Explanation: EIGRP uses a routing protocol code of D in the routing table.

Domain: Routing Fundamentals


7. What is the NTP Stratum?

  1. A unique identifier for the atomic clock

  2. A unique identifier for the local time server

  3. A measure of the distance from the clock source

  4. A measure of the distance from the client requesting time services

Correct Answer: c

Explanation: Large computer networks can have many devices acting as NTP servers. Where multiple NTP sources are available, NTP clients need some way of judging which time sources are likely to be the most accurate, and preventing timing loops. The NTP protocol achieves these aims by including a simple measure of the synchronization distance from the primary time source. This is known as the Stratum level. Stratum 0 devices (atomic clocks) are the most exact, but cannot be connected to via a network connection. A Stratum 0 device is used as a reference clock (or synchronization source) for a Stratum 1 time server.

Domain: Infrastructure Services


8. What type of NAT is in use given this command: ip nat inside source list 1 interface gi0/0 overload

  1. inside source static NAT

  2. inside source static PAT

  3. inside source dynamic NAT

  4. inside source dynamic PAT

Correct Answer: d

Explanation: The use of an access list (1) to specify the source addresses for translation indicates this is a dynamic NAT entry. The use of the overload keyword indicates PAT.

Domain: Infrastructure Services


9. What technologies are used in Cisco's implementation of Traceroute? (Choose three.)

  1. TCP

  2. UDP

  3. ICMP

  4. IGMP

  5. TTL

Correct Answer: b, c, e

Explanation: Cisco's Traceroute uses a combination of UDP and ICMP in order to provide the path between a source and a destination on the network. A Time to Live (TTL) value is also used.

10. Which of the following configurations will not return an Kill on a Cisco IOS device?

  1. hostname 9534

  2. hostname 9sw1

  3. hostname sw/102

  4. hostname sw-1209

Correct Answer: d

Explanation: Per the Cisco documentation for IOS – "The hostname is used in prompts and default configuration filenames. Do not expect case to be preserved. Uppercase and lowercase characters look the same to many internet software applications. It may seem appropriate to capitalize a name the same way you might do in English, but conventions dictate that computer names appear all lowercase. For more information, refer to RFC 1178, Choosing a Name for Your Computer. The name must also follow the rules for ARPANET hostnames. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphens. Names must be 63 characters or fewer. Creating an all numeric hostname is not recommended but the name will be accepted after an Kill is returned."
