In DHCP, what mechanism is used to ensure that multiple DHCP servers do not offer conflicting IP addresses?
- DHCP Snooping
- DHCP Relay
- DHCP Failover
- DHCP Lease Renewal
DHCP Failover is used to ensure that multiple DHCP servers coordinate and do not offer conflicting IP addresses to clients, enhancing network reliability.
Which system is utilized for sending and storing log messages in a network, helping in network management and security?
- DHCP
- DNS
- Syslog
- HTTP
Syslog is a system used for sending and storing log messages in a network, aiding in network management and security.
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.
