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.
In advanced network management, how does SDN (Software-Defined Networking) change the approach to device monitoring?
- Centralized Control
- Decentralized Monitoring
- Static Configuration
- Traditional SNMP Monitoring
SDN changes the approach to device monitoring in advanced network management by introducing centralized control, allowing for dynamic and programmable monitoring strategies.
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.
What is the primary purpose of the Spanning Tree Protocol (STP) in a network?
- Error detection
- Load balancing
- Preventing loops
- Reducing latency
The primary purpose of the Spanning Tree Protocol (STP) is to prevent loops in a network topology, ensuring a loop-free and stable network.
In DHCP, what is the purpose of the lease time?
- To specify the client's hardware address
- To determine the subnet mask
- To define the period a client can use an IP address
- To assign a default gateway
The lease time in DHCP defines the period during which a client can use the assigned IP address before renewal is required.
Which feature of SDN allows for the creation of virtual networks over the physical network infrastructure?
- Network Virtualization
- OpenFlow
- SDN Controller
- Traffic Engineering
Network virtualization in SDN enables the creation of virtual networks over the physical network infrastructure.
