In WAN optimization, what role does caching play?
- Reducing latency
- Storing frequently accessed data locally
- Prioritizing network traffic
- Increasing bandwidth
Caching in WAN optimization involves storing frequently accessed data locally, reducing the need to retrieve it from the remote server.
The network device that enables the creation of multiple virtual LANs on a single physical interface is known as a _______.
- Bridge
- Gateway
- Router
- Switch
The network device that enables the creation of multiple virtual LANs on a single physical interface is known as a Switch.
________ is a protocol that helps in automating the management of VLAN information across multiple switches.
- OSPF (Open Shortest Path First)
- RIP (Routing Information Protocol)
- STP (Spanning Tree Protocol)
- VTP (VLAN Trunking Protocol)
VTP (VLAN Trunking Protocol) is a protocol that helps in automating the management of VLAN information across multiple switches.
Which network device can be used to connect multiple LANs and manage the data traffic between them efficiently?
- Bridge
- Hub
- Router
- Switch
A router is a network device used to connect multiple LANs and efficiently manage data traffic between them.
How does QoS differentiate and prioritize traffic in a network with diverse applications and services?
- Based on MAC addresses
- Based on IP addresses
- Based on port numbers
- Based on application types
QoS differentiates and prioritizes traffic based on the types of applications and services running in the network.
In a high-security network environment, which firewall configuration approach would be most effective for controlling access to sensitive resources?
- Stateless Firewall
- Proxy Firewall
- Stateful Inspection
- Application Layer Firewall
An Application Layer Firewall is the most effective in a high-security environment as it operates at Layer 7, providing granular control over access to sensitive resources.
In the context of PPP, what is the role of LCP (Link Control Protocol)?
- Authentication
- Error Detection
- Frame Negotiation
- Establishing and Configuring the Point-to-Point Connection
LCP (Link Control Protocol) in PPP is responsible for establishing, configuring, and maintaining the point-to-point connection between network devices.
Which approach in network troubleshooting involves dividing the network into smaller segments or components to isolate the problem area?
- Top-Down
- Bottom-Up
- Divide and Conquer
- Lateral
The "Divide and Conquer" approach involves dividing the network into smaller segments or components to isolate the problem area systematically.
_____ is a technique used in WAN optimization to prioritize certain types of traffic.
- Quality of Service (QoS)
- Traceroute
- Bandwidth
- Latency
Quality of Service (QoS) is a technique used in WAN optimization to prioritize certain types of traffic.
A network administrator is tasked with improving the efficiency of a network that has grown complex over time with many specific routes. Which technique would be most effective?
- Dynamic Routing
- Route Aggregation
- Route Redistribution
- Static Routing
Route aggregation, also known as summarization, is an effective technique to improve the efficiency of a network with many specific routes by consolidating them into larger, summarized routes.
In QoS, ________ is used to ensure that no single traffic type consumes all available bandwidth.
- Traffic Shaping
- Bandwidth Policing
- Traffic Policing
- Congestion Management
Bandwidth Policing in QoS is used to ensure that no single traffic type consumes all available bandwidth.
How does VLSM differ from traditional fixed-length subnet masking?
- Traditional fixed-length subnet masking is more suitable for small networks, while VLSM is designed for large-scale networks
- Traditional fixed-length subnet masking provides more flexibility in address assignment than VLSM
- VLSM allows for variable-sized subnets within a network, while traditional fixed-length subnet masking uses a uniform subnet size
- VLSM is only applicable to IPv6, while traditional fixed-length subnet masking is used in IPv4 networks
VLSM (Variable Length Subnet Masking) allows for variable-sized subnets within a network, whereas traditional fixed-length subnet masking uses a uniform subnet size.
