CCNA Dump Questions 2015 - A Comprehensive Review

Are you preparing for the CCNA certification exam? Look no further! In this blog post, we will dive into the CCNA dump questions from 2015 and provide you with a comprehensive review to help you ace the exam. Let's get started!

Section 1: Network Fundamentals

Question 1: What is the purpose of a default gateway in a network?

Answer: A default gateway is used to forward network traffic between different subnets or networks.

Question 2: What is the difference between a hub and a switch?

Answer: A hub operates on the physical layer of the OSI model and broadcasts data to all connected devices. On the other hand, a switch operates on the data link layer and forwards data only to the intended recipient.

Section 2: Routing and Switching

Question 1: How does a router determine the best path for forwarding packets?

Answer: Routers use routing protocols, such as OSPF or EIGRP, to exchange routing information and build a routing table. Based on the routing table, the router determines the best path for forwarding packets.

Question 2: What is VLAN and why is it used?

Answer: VLAN stands for Virtual Local Area Network. It is used to logically divide a single physical network into multiple virtual networks, providing better security, scalability, and flexibility.

Section 3: WAN Technologies

Question 1: What is the difference between HDLC and PPP protocols?

Answer: HDLC is a Cisco proprietary protocol, while PPP (Point-to-Point Protocol) is a standardized protocol used for establishing a direct connection between two networking devices over serial links.

Question 2: What are the advantages of using Frame Relay in a network?

Answer: Frame Relay provides cost-effective data transmission, efficient bandwidth utilization, and supports various network topologies, making it suitable for connecting geographically dispersed networks.

Section 4: Network Security

Question 1: What is the purpose of an Access Control List (ACL)?

Answer: ACLs are used to control and filter network traffic based on set criteria, such as source/destination IP addresses or port numbers, providing network security and access control.

Question 2: What are the differences between symmetric and asymmetric encryption?

Answer: Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption uses a pair of public and private keys. Asymmetric encryption provides better security but is slower than symmetric encryption.

Section 5: Network Management

Question 1: What is SNMP and how is it used in network management?

Answer: SNMP (Simple Network Management Protocol) is used to monitor and manage network devices. It allows network administrators to gather information, configure devices, and detect network issues.

Question 2: What is the purpose of a syslog server?

Answer: A syslog server collects and stores log messages from various network devices. It helps in troubleshooting, auditing, and monitoring the network for any anomalies or security breaches.

By understanding and practicing these CCNA dump questions from 2015, you will have a solid foundation for passing the CCNA certification exam with flying colors. Good luck on your journey to becoming a certified networking professional!
