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.
In a data center, the network team is implementing EtherChannel to enhance throughput and redundancy. What configuration aspects are critical to ensure optimal performance and reliability?
- DHCP configuration, broadcast storm control, and OSPF areas
- Duplex settings, access control lists, and SNMP versions
- Link aggregation mode, spanning-tree protocol parameters, and interface MTU
- NAT settings, VLAN pruning, and HSRP priorities
Configuring link aggregation mode, spanning-tree protocol parameters, and interface MTU are critical aspects for ensuring optimal performance and reliability when implementing EtherChannel in a data center.
Which protocol is commonly used for communication between the SDN controller and network devices?
- SNMP
- OSPF
- OpenFlow
- BGP
OpenFlow is a widely used protocol for communication between the SDN controller and network devices, enabling centralized control.
An organization wants to block all incoming traffic from a specific IP range due to security concerns. Which feature of ACLs would be most effective?
- Dynamic ACL
- Named ACL
- Reflexive ACL
- Standard ACL
Standard ACLs can filter traffic based on source IP addresses, making them effective for blocking specific IP ranges.
What is the purpose of subnetting in IPv4 networks?
- To improve network security
- To increase the number of available IP addresses
- To provide a way to group hosts logically and efficiently
- To reduce network congestion
Subnetting in IPv4 networks serves the purpose of logically grouping hosts to optimize network management and improve efficiency.
How does route summarization impact the convergence time in a dynamic routing environment?
- Accelerates convergence
- Delays convergence
- Has no impact on convergence
- Improves route computation
Route summarization can potentially delay convergence in a dynamic routing environment by limiting the exchange of detailed route information between routers.
What is the primary function of Border Gateway Protocol (BGP) in networking?
- Dynamic Routing
- Interior Gateway Protocol (IGP)
- Exterior Gateway Protocol (EGP)
- Link-State Routing
The primary function of Border Gateway Protocol (BGP) is to exchange routing information between different Autonomous Systems (AS) on the Internet, making it an Exterior Gateway Protocol (EGP).
________ encryption is commonly used in SSH for securing remote management sessions.
- Symmetric
- Asymmetric
- Public Key
- Private Key
Asymmetric encryption is commonly used in SSH for securing remote management sessions.
