What is the total number of bits used in an IPv4 address?
- 128
- 16
- 32
- 64
An IPv4 address uses a total of 32 bits.
A ________ port on a switch allows traffic from multiple VLANs to pass through while keeping the traffic separate.
- Access
- Tagged
- Trunk
- Untagged
A Trunk port on a switch allows traffic from multiple VLANs to pass through while keeping the traffic separate.
A _________ topology typically requires more cabling than other topologies but offers robustness and fault tolerance.
- Bus
- Mesh
- Ring
- Star
A Mesh topology typically requires more cabling than other topologies but offers robustness and fault tolerance. Each device is connected to every other device, providing multiple paths for data transmission.
In network management, ________ is a method that provides a centralized platform to control different network devices from various vendors.
- SNMP (Simple Network Management Protocol)
- Syslog
- ICMP (Internet Control Message Protocol)
- SMTP (Simple Mail Transfer Protocol)
SNMP (Simple Network Management Protocol) is a method used in network management to provide a centralized platform for controlling different network devices from various vendors.
How does serverless computing differ from traditional cloud computing models?
- Serverless computing abstracts server management entirely, and users only pay for actual usage
- Serverless computing relies on physical servers for resource allocation
- Traditional cloud computing models are event-driven, while serverless models are request-driven
- Serverless computing uses virtualization technology exclusively
Serverless computing differs from traditional cloud computing by abstracting server management entirely, and users only pay for actual usage, eliminating the need for provisioning and managing servers.
In complex network environments, why is it crucial to document and analyze network change logs during troubleshooting?
- Change logs provide a historical record of network configurations and changes
- Change logs are unnecessary and can be ignored during troubleshooting
- Analyzing change logs only helps in identifying minor issues
- Change logs are useful only for auditing purposes
Documenting and analyzing network change logs in complex environments is crucial as they provide a historical record of network configurations and changes, aiding in identifying potential causes of issues.
In an organization looking to scale its network infrastructure with minimal physical changes, which SDN capability would be most critical?
- Network Function Virtualization (NFV)
- Southbound API
- Northbound API
- Control Plane Separation
Network Function Virtualization (NFV) in SDN allows scaling the network infrastructure by virtualizing network functions, minimizing the need for physical changes.
In a stacked configuration, individual switches are interconnected using a ________ link.
- Backbone
- Mesh
- Trunk
- Uplink
In a stacked configuration, individual switches are interconnected using a trunk link to facilitate communication and coordination.
How does GRE tunneling differ from traditional VPN tunneling in terms of encryption and security features?
- GRE focuses on providing a simple encapsulation method without inherent encryption.
- GRE offers stronger encryption and security features compared to traditional VPNs.
- GRE and traditional VPNs have identical encryption and security features.
- GRE and traditional VPNs do not support encryption.
GRE primarily provides encapsulation and does not inherently offer encryption, unlike traditional VPNs that focus on security features.
What is the main security benefit of using NAT in a network infrastructure?
- It automatically detects and blocks malicious traffic.
- It hides internal IP addresses from external networks.
- It implements strong access control policies.
- It provides encryption for all transmitted data.
The main security benefit of using NAT is that it hides internal IP addresses from external networks, adding a layer of security by obscuring the internal network structure.
