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.
Automating network security tasks is often done using ________, which help in identifying and mitigating security threats.
- 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.
OSPF uses ________ as its algorithm for computing the shortest path through the network.
- Bellman-Ford algorithm
- Dijkstra's algorithm
- Floyd-Warshall algorithm
- Johnson's algorithm
OSPF uses Dijkstra's algorithm for computing the shortest path through the network.
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.
