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 switch stacking, what role does the master switch play?
- Backup Configuration
- Centralized Management
- Forwarding Traffic Only
- Redundancy Only
In switch stacking, the master switch plays a role in centralized management, overseeing the operation and configuration of the entire stack.
In a scenario where an organization has a limited number of IP addresses but requires several small networks, how should the subnetting be designed?
- Classful Subnetting
- Classless Subnetting
- Supernetting
- Variable Length Subnet Masking (VLSM)
Variable Length Subnet Masking (VLSM) is the appropriate subnetting technique for designing subnets of various sizes, conserving IP addresses for small networks.
EtherChannel can be implemented using either _______ or _______ as the control protocol.
- LACP
- PAgP
- STP
- VTP
EtherChannel can be implemented using either PAgP (Port Aggregation Protocol) or LACP (Link Aggregation Control Protocol) as the control protocol.
What type of NAT maps multiple private IP addresses to a single public IP address using different ports?
- Dynamic NAT
- NAPT (Network Address Port Translation)
- PAT (Port Address Translation)
- Static NAT
PAT (Port Address Translation) maps multiple private IP addresses to a single public IP address using different ports for differentiation.
