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.
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.
________ is a Cisco protocol that ensures high availability by providing a single virtual IP address and multiple gateways for load balancing.
- HSRP (Hot Standby Router Protocol)
- OSPF (Open Shortest Path First)
- VRRP (Virtual Router Redundancy Protocol)
- GLBP (Gateway Load Balancing Protocol)
GLBP (Gateway Load Balancing Protocol) is a Cisco protocol that ensures high availability by providing a single virtual IP address and multiple gateways for load balancing.
_________ 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.
