Which protocol within IPSec is used to provide data integrity and authentication?

  • AH (Authentication Header)
  • ESP (Encapsulating Security Payload)
  • IKE (Internet Key Exchange)
  • SSL (Secure Sockets Layer)
The Authentication Header (AH) protocol within IPSec is used to provide data integrity and authentication.

What is a key disadvantage of using a star topology in very large networks?

  • Complex Wiring
  • High Maintenance Cost
  • Limited Scalability
  • Single Point of Failure
A key disadvantage of using a star topology in very large networks is limited scalability. As more devices are added, the central hub may become a bottleneck for data traffic.

In a network, _______ is used to connect segments of a LAN and contains logic to filter traffic based on MAC addresses.

  • Hub
  • Repeater
  • Router
  • Switch
In a network, a Switch is used to connect segments of a LAN and contains logic to filter traffic based on MAC addresses.

Which type of firewall uses a defined set of rules to decide whether to allow or block network traffic?

  • Proxy firewall
  • Stateful firewall
  • Stateless firewall
  • Application-layer firewall
A stateful firewall uses a defined set of rules to decide whether to allow or block network traffic based on the state of connections.

_________ in cloud computing refers to the distribution of network resources to ensure optimal balance and performance.

  • Load Balancing
  • Scalability
  • Virtualization
  • Redundancy
Load balancing in cloud computing involves distributing network resources to ensure optimal balance and performance.

In configuring a network that supports both IPv4 and IPv6, what is a key consideration for ensuring seamless communication between different IP version hosts?

  • Dual-Stack Configuration
  • Port Forwarding
  • Tunneling
  • VLAN Configuration
Tunneling is a key consideration for ensuring seamless communication between different IP version hosts in a network supporting both IPv4 and IPv6. Tunneling encapsulates IPv6 packets within IPv4 packets for transmission.

Which feature in switch configuration allows for assigning multiple ports to a single broadcast domain?

  • Port mirroring
  • STP
  • Trunking
  • VLAN
Virtual LANs (VLANs) in switch configuration allow for assigning multiple ports to a single broadcast domain, improving network segmentation and management.

A network administrator must design a QoS policy that dynamically adjusts priorities based on network load. Which advanced QoS feature should they consider?

  • Class-Based Weighted Fair Queuing (CBWFQ)
  • Low Latency Queuing (LLQ)
  • Weighted Random Early Detection (WRED)
  • AutoQoS
AutoQoS is an advanced QoS feature that dynamically adjusts priorities based on network load, providing an automated approach to QoS policy design.

For a business requiring remote access to servers in its private network from the internet, what NAT feature would be most appropriate to set up?

  • Dynamic NAT
  • PAT
  • Port Forwarding
  • Static NAT
Port Forwarding would be the most appropriate NAT feature for allowing remote access to servers in a private network from the internet, forwarding specific ports to internal servers.
