chapter 7 - 1480
You are configuring a network switch and need to control network traffic based on MAC addresses. Which feature allows you to specify which devices are allowed to communicate on specific switch ports?
In a large enterprise network, you want to efficiently manage and monitor network switches. Which network management protocol is commonly used to retrieve information about switch performance, status, and configuration?
You are responsible for connecting multiple switches in a network to provide redundancy and prevent network loops. What technology or protocol can help manage and prevent loops in switched networks?
Spanning Tree Protocol (STP)
You need to monitor and control network traffic on a switch by inspecting data packets at the application layer. What network device allows you to do deep packet inspection and apply access control policies based on application-layer data?
You want to prevent unauthorized devices from connecting to your network through unused switch ports. What switch port security feature allows you to disable unused ports and restrict access?
What is the primary function of the core layer in a hierarchical network design?
To provide high-speed backbone connections
In a three-layer hierarchical network design, which layer is responsible for connecting distribution switches to the access layer switches and aggregating traffic from access layer devices?
In a spine-and-leaf network, you need to route traffic between different VLANs at the aggregation layer. What device is commonly used to perform inter-VLAN routing in this architecture?
In a large data center, leaf switches are responsible for connecting end-user devices and servers to the network. What is the primary consideration when selecting leaf switches for this environment?
Scalability and the number of ports
Your organization is experiencing frequent network configuration changes and struggles with network agility. You want to simplify network management and optimize traffic flows. Which aspect of SDN can best address these challenges?
SDN control plane
You work for a company that operates a complex, geographically dispersed network. You need to implement SDN to efficiently manage network resources, including routing and traffic engineering. Which SDN component would you focus on to achieve this?
SDN service layer
Your organization is looking to simplify network provisioning and reduce the complexity of configuring individual devices. What key advantage of SDN can help achieve this goal?
Centralized control and policy management
In your SDN deployment, you want to gather real-time network statistics, monitor device performance, and receive alerts about network issues. What protocol can assist in this network monitoring and management?
SNMP (Simple Network Management Protocol)
Your organization is planning to implement a SAN and you want to minimize the physical cabling and network complexity. What SAN technology allows you to use the existing Ethernet network for SAN traffic?
FCoE (Fibre Channel over Ethernet)
Your organization is planning to implement virtualization for improved resource utilization. You need to decide between Type 1 and Type 2 hypervisors. What should be your primary consideration when choosing between these hypervisor types?
Performance and resource efficiency
You are responsible for selecting a network connection type for virtual machines in your cloud environment. What connection type provides direct, high-speed connectivity between virtual machines on the same host while bypassing the physical network infrastructure?
Your organization is considering implementing Network Function Virtualization (NFV) to improve network flexibility. What is one of the primary benefits of NFV in this context?
Reduced complexity in network configuration
Your organization is concerned about the potential security risks associated with virtualization. What is a disadvantage or challenge of virtualization in terms of security?
Vulnerabilities in hypervisors or management interfaces
Your organization is implementing a virtualized network infrastructure, and you want to improve network agility and scalability. What virtualization technology can
Network Function Virtualization (NFV)
