What is EtherChannel primarily used for in network configurations?
- Assigning IP addresses
- Encrypting data transmission
- Load balancing
- Reducing network congestion
EtherChannel is primarily used for load balancing in network configurations, distributing traffic across multiple links.
What is the primary purpose of using passwords in network device security?
- Authentication
- Authorization
- Confidentiality
- Integrity
Passwords in network device security primarily serve the purpose of authentication, ensuring that users are who they claim to be.
What is the effect of placing an ACL close to the source of traffic in a network?
- Causes network congestion
- Decreases network performance
- Has no impact on network traffic
- Increases network security
Placing an ACL close to the source of traffic increases network security by filtering unwanted traffic before it enters the network.
What is the primary purpose of SNMP (Simple Network Management Protocol) in network management?
- Network Monitoring
- Device Configuration
- File Sharing
- Web Browsing
SNMP is primarily used for network monitoring, allowing devices to be managed and monitored remotely.
In QoS, ________ is a method used to measure and control the rate of traffic sent to the network.
- Policing
- Shaping
- Dropping
- Queuing
Policing in QoS is a method used to measure and control the rate of traffic sent to the network.
How does a stateful firewall differ from a stateless firewall in terms of traffic filtering?
- Stateless firewall filters traffic based on source and destination information
- Stateless firewall examines the state of active connections
- Stateful firewall filters traffic based on source and destination information
- Stateful firewall does not keep track of the state of connections
A stateful firewall filters traffic based on the state of active connections, considering the context of the traffic.
QoS policies applied to a network affect which of the following: Bandwidth allocation, Delay, Jitter, or All of these?
- Bandwidth allocation
- Delay
- Jitter
- All of these
QoS policies applied to a network can affect all of these factors: Bandwidth allocation, Delay, and Jitter.
What type of WAN connection uses a private network to securely connect remote sites over the internet?
- VPN (Virtual Private Network)
- MPLS
- ISDN (Integrated Services Digital Network)
- DSL
A VPN (Virtual Private Network) uses a private network to securely connect remote sites over the internet.
The _______ topology is preferred in networks where reconfiguration, scalability, and fault tolerance are critical factors.
- Hybrid
- Mesh
- Ring
- Star
The Mesh topology is preferred in networks where reconfiguration, scalability, and fault tolerance are critical factors. Mesh networks provide high fault tolerance and scalability due to multiple connections.
In a network with high mobility and frequent device changes, what DHCP feature should be emphasized to manage network addresses effectively?
- DHCP Reservation
- DHCP Relay Agent
- DHCP Lease Time
- DHCP Option 82
A shorter DHCP lease time should be emphasized in a network with high mobility and frequent device changes to manage network addresses effectively.
