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.
