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.
What type of topology combines characteristics of linear bus and star topologies, and is commonly used in wireless networks?
- Bus
- Mesh
- Ring
- Star
A bus topology combines characteristics of linear bus and star topologies and is commonly used in wireless networks.
In a network using NAT, what happens to the IP address of a packet as it leaves the local network and enters the internet?
- It is encrypted
- It is translated to a private IP address
- It is translated to a public IP address
- It remains the same
In a network using NAT, the private IP address of a packet is translated to a public IP address as it leaves the local network and enters the internet.
A network administrator needs to ensure secure remote access to network devices for configuration and troubleshooting. What protocol or method would be most appropriate?
- Telnet
- SSH (Secure Shell)
- HTTP
- SNMPv1
Secure Shell (SSH) is the appropriate protocol for secure remote access to network devices for configuration and troubleshooting, providing encrypted communication.
In IPv6, ________ addresses are used to send packets to a group of interfaces.
- Anycast
- Broadcast
- Multicast
- Unicast
In IPv6, multicast addresses are used to send packets to a group of interfaces. Multicast enables efficient communication to multiple hosts.
What device operates primarily at the physical layer and helps in connecting multiple devices in a network by broadcasting data to all ports?
- Bridge
- Hub
- Router
- Switch
A hub operates primarily at the physical layer and connects multiple devices in a network by broadcasting data to all ports.
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.
