An organization is looking to improve network performance by segmenting the network and reducing unnecessary traffic. Which device would be most suitable for this purpose?
- Bridge
- Hub
- Router
- Switch
A switch is ideal for improving network performance by segmenting the network, reducing unnecessary traffic, and providing better bandwidth utilization.
What is the purpose of the Anycast address in IPv6?
- Broadcast communication to all interfaces
- Multicast communication to all interfaces
- Unicast communication to any one of several interfaces
- Unicast communication to the nearest interface
An Anycast address in IPv6 allows communication to any one of several interfaces, typically choosing the nearest one.
ACLs are used to filter traffic based on which criteria in a network?
- Source and Destination IP Addresses
- Source and Destination MAC Addresses
- Source and Destination Physical Locations
- Source and Destination Port Numbers
ACLs are used to filter network traffic based on source and destination IP addresses.
In IPv6, what is the primary role of the Neighbor Discovery Protocol (NDP)?
- Address Resolution Protocol (ARP) replacement
- Dynamic Host Configuration Protocol (DHCP) functionality
- Internet Control Message Protocol version 6 (ICMPv6) replacement
- Routing Information Protocol (RIP) for IPv6
The Neighbor Discovery Protocol (NDP) in IPv6 serves as a replacement for the Address Resolution Protocol (ARP) in IPv4, facilitating address resolution in the network.
In a network implementing both Port Security and VLANs, how does Port Security interact with different VLANs assigned to a single port?
- It applies the same security settings to all VLANs
- It causes VLAN mismatch errors
- It enforces security independently for each VLAN
- It ignores VLAN information
Port Security enforces security independently for each VLAN on a port, ensuring that security policies are applied appropriately to each VLAN.
________ is a feature of IPv6 that allows multiple IP addresses to be assigned to a single network interface.
- Anycast
- DHCPv6 (Dynamic Host Configuration Protocol for IPv6)
- Multicast
- Stateless Address Autoconfiguration
Stateless Address Autoconfiguration is a feature of IPv6 that allows multiple IP addresses to be assigned to a single network interface without the need for a DHCPv6 server.
Describe the function of a Traffic Policer in a QoS environment.
- A Traffic Policer monitors incoming traffic, enforces traffic policies, and takes actions such as dropping or marking packets based on predefined rules.
- Traffic Policers are responsible for shaping outbound traffic to conform to specified profiles.
- Traffic Policers are used to prioritize outbound traffic based on application requirements.
- A Traffic Policer ensures that only specific types of traffic are allowed in the network, blocking all other traffic.
In a QoS environment, a Traffic Policer monitors incoming traffic, enforces traffic policies, and takes actions such as dropping or marking packets based on predefined rules.
In which topology is every network device connected to two other devices along a circular path, offering redundancy and reliability?
- Bus
- Mesh
- Ring
- Star
In a ring topology, every network device is connected to two other devices in a circular path, providing redundancy and reliability.
________ is a method in VPNs to control which traffic is sent through the VPN tunnel and which accesses the internet directly.
- Tunnel Mode
- Split Tunneling
- Transport Mode
- Site-to-Site VPN
Split Tunneling is a method in VPNs to control which traffic is sent through the VPN tunnel and which accesses the internet directly.
To enhance security, GRE tunnels are frequently paired with ______, which provides encryption and authentication.
- IPsec
- OSPF
- VLAN
- SNMP
To enhance security, GRE tunnels are frequently paired with IPsec, which provides encryption and authentication.
