Chassis aggregation is mainly used to improve what aspect of network performance?
- Bandwidth
- Latency
- Reliability
- Security
Chassis aggregation is mainly used to improve bandwidth in a network, combining the capacity of multiple physical devices.
What is the significance of the 'native VLAN' on a trunk port?
- It carries only management traffic
- It is reserved for high-priority data
- It is the default VLAN for untagged traffic on the trunk
- It is used for voice traffic
The native VLAN on a trunk port is the default VLAN for untagged traffic, facilitating communication between devices that do not understand VLAN tagging.
In a large enterprise with multiple branches and a constantly evolving network, which routing strategy would best suit their needs for efficiency and reliability?
- Default Routing
- Dynamic Routing
- Policy-Based Routing
- Static Routing
Dynamic Routing is ideal for a large enterprise with a constantly evolving network as it provides efficiency and reliability by adapting to changes automatically.
An organization with fluctuating workload demands is seeking a cloud solution that offers flexibility and efficient resource utilization. What cloud computing feature would be most beneficial for them?
- Auto-scaling
- Load Balancing
- High Availability
- Disaster Recovery
Auto-scaling is a cloud computing feature that dynamically adjusts resources based on workload demands, providing flexibility and efficient resource utilization for organizations with fluctuating workloads.
The command 'access-list 100 permit tcp any host 192.168.1.1 eq 80' in Cisco routers is an example of a(n) ________ ACL.
- Dynamic
- Extended
- Named
- Standard
The command 'access-list 100 permit tcp any host 192.168.1.1 eq 80' in Cisco routers is an example of an Extended ACL.
The _________ feature of Layer 2 switches is crucial for preventing unauthorized DHCP servers from assigning IP addresses.
- DHCP Snooping
- MAC Address Filtering
- STP
- VLAN
DHCP Snooping is crucial for preventing unauthorized DHCP servers from assigning IP addresses in Layer 2 switches.
How does a next-generation firewall (NGFW) enhance network security compared to traditional firewalls?
- NGFW integrates intrusion prevention, application awareness, and other advanced features for more comprehensive protection
- Traditional firewalls have faster throughput compared to NGFW
- NGFW relies solely on packet filtering, which is more efficient than traditional methods
- Traditional firewalls are more scalable and adaptable to evolving threats
Next-generation firewalls (NGFW) enhance network security by integrating intrusion prevention, application awareness, and other advanced features for more comprehensive protection compared to traditional firewalls.
An ISP needs to control network congestion during peak hours. What QoS strategy should they employ to manage bandwidth usage effectively?
- Weighted Random Early Detection (WRED)
- Traffic Policing
- Class-Based Weighted Fair Queuing (CBWFQ)
- Congestion Avoidance
Weighted Random Early Detection (WRED) is a congestion avoidance technique that an ISP can use to control network congestion during peak hours.
In which protocol can multiple routers be configured to share the load of forwarding IP packets without being detected by the end hosts?
- HSRP
- VRRP
- GLBP
- OSPF
GLBP (Gateway Load Balancing Protocol) is a protocol where multiple routers can be configured to share the load of forwarding IP packets without being detected by the end hosts.
