A ________ topology is characterized by a central node to which all other nodes are connected, forming a layout resembling a star.
- Bus
- Mesh
- Ring
- Star
A Star topology is characterized by a central node to which all other nodes are connected, forming a layout resembling a star.
In what topology do data packets travel from node to node in a ring, with each node having the chance to transmit?
- Bus
- Mesh
- Ring
- Star
In a ring topology, data packets travel from node to node in a ring, with each node having the chance to transmit when it receives control.
Syslog uses what protocol for transmitting log messages in a plain text format?
- TCP
- UDP
- ICMP
- IP
Syslog uses the UDP (User Datagram Protocol) for transmitting log messages in a plain text format.
AAA in network security stands for Authentication, Authorization, and ________.
- Accounting
- Access
- Authentication
- Authorization
AAA in network security stands for Authentication, Authorization, and Accounting, representing the three core components of network access control.
How does DNSSEC enhance the security of the DNS?
- By encrypting DNS queries
- By providing digital signatures for DNS data
- By blocking malicious DNS traffic
- By anonymizing DNS requests
DNS Security Extensions (DNSSEC) enhance DNS security by providing digital signatures for DNS data, ensuring data integrity and authenticity.
A company is expanding its network infrastructure and requires a setup that allows for easy scalability and centralized management. Which technology would best suit their needs?
- MPLS
- OSPF
- SD-WAN
- VLAN
SD-WAN (Software-Defined Wide Area Networking) would best suit the company's needs as it offers easy scalability and centralized management of network infrastructure.
In a network that requires both IPv4 and IPv6 support with the capability of load balancing over unequal paths, which routing protocol would be most suitable?
- BGP
- EIGRP
- OSPF
- RIPng
EIGRP (Enhanced Interior Gateway Routing Protocol) supports both IPv4 and IPv6, along with the capability of load balancing over unequal paths.
Which of the following is a common reason for using NAT in a network?
- Boosting wireless signal strength
- Conserving public IP addresses
- Enhancing data encryption
- Increasing network complexity
A common reason for using NAT is to conserve public IP addresses by allowing multiple devices in a private network to share a single public IP address.
For a company that needs a routing protocol to efficiently handle frequent network topology changes without causing significant traffic due to routing updates, what would be the best choice?
- BGP
- EIGRP
- OSPF
- RIP
OSPF (Open Shortest Path First) is a link-state routing protocol designed to efficiently handle frequent network topology changes without causing significant traffic due to routing updates.
A company is expanding its network infrastructure to support IPv6. What should be considered for efficient IPv6 routing and address allocation?
- Stateless Address Autoconfiguration (SLAAC)
- Network Address Translation (NAT)
- Dynamic Host Configuration Protocol (DHCPv6)
- Subnetting
For efficient IPv6 routing and address allocation, Stateless Address Autoconfiguration (SLAAC) is a key consideration. SLAAC allows devices to configure their IPv6 addresses automatically.
