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.
