- Intrusion Detection Systems
- Firewalls
- VPNs
- Access Control Lists
Automating network security tasks is often done using Intrusion Detection Systems, which help in identifying and mitigating security threats.
Which feature in Layer 2 security helps prevent DHCP starvation attacks?
- DHCP Snooping
- MAC Filtering
- Port Security
- VLANs
DHCP Snooping is a Layer 2 security feature that helps prevent DHCP starvation attacks by inspecting and filtering DHCP messages.
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, what does the term 'classification' refer to?
- Identifying and categorizing network traffic
- Adjusting the speed of data transmission
- Managing network congestion
- Allocating IP addresses
In Quality of Service (QoS), 'classification' involves identifying and categorizing network traffic based on specific criteria to prioritize or treat it differently.
The use of _________ in QoS refers to inspecting the contents of data packets to assign them to the appropriate traffic class.
- Policing
- Shaping
- Queuing
- Classification
In QoS, the use of classification refers to inspecting the contents of data packets to assign them to the appropriate traffic class.
In a scenario where a network requires both data and electrical power transmission to devices, which technology is typically used?
- Fiber Optic
- Power over Ethernet (PoE)
- Token Ring
- Twisted Pair
Power over Ethernet (PoE) is the technology used when a network requires both data and electrical power transmission to devices, simplifying cabling and device power requirements.
What is the primary benefit of using MLPPP over traditional PPP in a network environment?
- Increased Bandwidth
- Enhanced Security
- Load Balancing
- Error Correction
MLPPP (Multilink Point-to-Point Protocol) offers load balancing, enabling the aggregation of multiple physical links into a single logical link to enhance network bandwidth.
What OSI layer is equivalent to the combination of the Session, Presentation, and Application layers in the TCP/IP model?
- Application Layer
- Data Link Layer
- Network Layer
- Transport Layer
The Application Layer in the OSI model is equivalent to the combination of the Session, Presentation, and Application layers in the TCP/IP model.
GRE tunnels are primarily used for which of the following purposes in a network?
- Encryption
- Compression
- Tunneling
- Authentication
GRE tunnels are primarily used for tunneling purposes in a network, allowing the encapsulation of a wide variety of network layer protocols.
