What is the primary goal of WAN optimization in a corporate network environment?
- Reduce latency
- Increase bandwidth
- Enhance security
- Minimize packet loss
The primary goal of WAN optimization is to increase the efficiency of data transfer across a corporate network by enhancing bandwidth utilization.
A company is transitioning to a fully automated network system. Which scripting language should they prioritize for their network engineers to learn for efficient automation and script-based configurations?
- Python
- Java
- C++
- Ruby
Python is widely used for network automation due to its simplicity, readability, and extensive libraries like Netmiko and NAPALM.
In a scenario where network issues are intermittent, using ___________ can help in capturing and analyzing transient events.
- Packet Captures
- SNMP
- NetFlow
- Syslog
Packet captures are invaluable in capturing and analyzing transient events, especially in scenarios with intermittent network issues.
Which topology is best suited for large-scale networks due to its scalability and decentralized nature?
- Bus
- Mesh
- Star
- Tree
A tree topology is best suited for large-scale networks due to its scalability and decentralized nature. It combines elements of bus and star topologies.
What is EtherChannel primarily used for in network configurations?
- Assigning IP addresses
- Encrypting data transmission
- Load balancing
- Reducing network congestion
EtherChannel is primarily used for load balancing in network configurations, distributing traffic across multiple links.
What is the primary purpose of using passwords in network device security?
- Authentication
- Authorization
- Confidentiality
- Integrity
Passwords in network device security primarily serve the purpose of authentication, ensuring that users are who they claim to be.
A network administrator is implementing a new policy to enhance device security. They need a protocol that encrypts both authentication and session data. Which protocol should they use?
- SSL/TLS
- SNMP
- SSH
- DHCP
SSH (Secure Shell) is a protocol that encrypts both authentication and session data, providing enhanced device security.
_________ is used to allow multiple devices on a private network to be mapped to a single public IP address but with different port numbers.
- Dynamic NAT
- NAT Overload
- PAT (Port Address Translation)
- Static NAT
PAT (Port Address Translation) is used to allow multiple devices on a private network to be mapped to a single public IP address but with different port numbers.
In a complex network, what is the primary challenge when implementing VLSM?
- Incompatibility with DHCP
- Increased routing table complexity
- Lack of support from network devices
- Limited number of available IP addresses
In complex networks, the primary challenge when implementing VLSM is increased routing table complexity, as it requires routers to maintain information about subnets of varying sizes.
A network administrator discovers that unauthorized devices are connecting to the network. Which Layer 2 security feature should be implemented to control access based on MAC addresses?
- DHCP Snooping
- MAC Spoofing
- Port Security
- VLANs
Port Security is a Layer 2 security feature that controls access based on MAC addresses, helping prevent unauthorized devices from connecting to the network.
