CCNA PRACTICE TEST QUESTIONS 1
WITH CORRECT ANSWERS
From a network perspective, how is a server a different endpoint than a user
workstation? - Correct Answers -A server requires more bandwidth.
Which two characteristics apply to small office/home office (SOHO) routers? - Correct
Answers -They have a web-based administration interface and they have integrated
security functionality.
What is the purpose of the metric parameter of a route? - Correct Answers -It binds a
numeric value to the path to a network.
Where should a firewall be located to protect a network from the public Internet? -
Correct Answers -Between the Internet and the edge router.
What are two reasons for choosing Transport Layer Security over IP Security
encryption? - Correct Answers -IPsec requires dedicated software installed on host, and
TLS can be used for encrypting traffic to public websites. IPsec can encrypt the entire I
P packet, while TLS encrypts only the application level data, which makes IPsec a more
flexible choice for a broader range of applications.
How do you view the DHCP assigned IP address lease time on a Cisco device? -
Correct Answers -With the command show I P DHCP binding.
What 3 characteristics differentiate Ansible from other automation tools? - Correct
Answers -It is agentless, it is written in Python, and it uses YAML definitions.
What task makes configuring network devices more efficient and reduces errors? -
Correct Answers -Device provisioning configures network devices more efficiently,
faster, and with fewer errors because human interaction with each network device is
decreased.
How are IPv6 addresses similar to IPv4 addresses? - Correct Answers -Devices that
need to communicate with each other need to be in the same subnet.
When using IPv6, what are the next hop addresses? - Correct Answers -The next hop
IPv6 address will be a link-local IPv6 address. Look at the configured link-local
addresses on neighbor devices to determine next -hop addresses.
, How do you find the default gateway when using IPv6 addressing? - Correct Answers -
Look at the IPv6 address of the next hop that is in the same subnet.
Give two implementation characteristics of MPLS VPN. - Correct Answers -1) The
service provider network can be represented as a router from the customer perspective.
2) The service provide can implement MPLS L3VPN.
You have set up a SOHO to work from home and are using broadband internet with a
remote-access VPN to connect to your company resources. How can you establish a
VPN tunnel? - Correct Answers -You can use a web browser to establish a VPN tunnel.
Remote-access VPN allows you to establish VPNs using VPN-client software or a web-
based client. Remote-access VPNs are not statically set up. Site-to-site VPNs require
VPN-capable devices to connect to the VPN gateway on the company's side.
Which two types of cables can be used to connect to the console port of a Cisco router?
- Correct Answers -Rollover or USB.
Which type of cable is typically used to connect a core switch with a data center switch,
where bandwidth higher than 40 Gbps and low cost are required? - Correct Answers -
Multimode fiber.
In which situation would you choose to use UDP instead of TCP for IP applications? -
Correct Answers -When speed of delivery is more important than error correction in IP
packet transmissions.
What three fields are included in a TCP header? - Correct Answers -Destination port,
Flags, and Window size.
What happens when an IPv6 address autoconfigures itself? - Correct Answers -The 7th
bit of the I P address is flipped.
Which type of address is automatically assigned to a physical interface when IPv6 is
enabled on that interface? - Correct Answers -A link-local address.
Give 3 characteristics that apply to the 802.1Q protocol. - Correct Answers -1) It carries
untagged frames. 2) It modifies the 802.3 frame header. 3) It uses an internal tagging
mechanism.
What happens if a port that is assigned to a VLAN is shut down? - Correct Answers -If a
port or the VLAN assigned to it are shut down, no traffic can flow through.
Which component is used to generate a signal for single-mode fiber connections? -
Correct Answers -A laser transmitter.
