CCNA Exam Questions 2019 – Test Your Networking Knowledge

The CCNA (Cisco Certified Network Associate) certification is a widely recognized credential for networking professionals. It validates your knowledge and skills in installing, configuring, and troubleshooting networks. If you are preparing for the CCNA exam in 2019, it is crucial to familiarize yourself with the type of questions you might encounter.

1. What are the advantages of using a router?

A) Allows for the connection of multiple networks, facilitating data transmission between them.
B) Acts as a firewall, enhancing network security by blocking unauthorized access.
C) Provides NAT (Network Address Translation) functionality, allowing private IP addresses to access the internet.

2. What is the purpose of subnetting?

A) To divide a large network into smaller subnetworks, improving performance and managing IP address allocation more efficiently.
B) To establish secure connections between remote networks using encryption protocols.
C) To prevent unauthorized access by setting access control lists (ACLs) on routers.

3. Which protocol is used for automatically assigning IP addresses in a network?

A) DHCP (Dynamic Host Configuration Protocol)
B) DNS (Domain Name System)
C) FTP (File Transfer Protocol)

4. How does a switch differ from a hub?

A) Switches operate at the data link layer (Layer 2) of the OSI model and can divide a network into multiple collision domains, reducing network congestion. Hubs operate at the physical layer (Layer 1), and any data received is sent to all devices connected to it, leading to collisions and decreased network performance.
B) Switches connect networks together, while hubs only connect devices within a network.
C) Switches can perform advanced routing functions, while hubs cannot.

5. What is the purpose of VLANs (Virtual Local Area Networks)?

A) To logically separate a physical network into multiple virtual networks, enhancing security and improving network performance.
B) To connect geographically dispersed networks using virtual tunnels.
C) To establish secure remote access connections to a company’s internal network.

These are just a few examples of the types of questions you might encounter in the CCNA exam. It is essential to study and practice thoroughly to ensure success on the certification test. Remember to review the official Cisco CCNA exam topics, practice with hands-on labs, and explore additional study resources.

Good luck with your CCNA exam preparation!
