What is a potential drawback of improper route summarization in a network?
- Enhanced network security
- Improved scalability
- Increased routing table size
- Reduced network latency
Improper route summarization can lead to an increased routing table size, negatively impacting network performance and scalability.
_________ topology is known for its simplicity and is commonly used for small local area networks.
- Bus
- Mesh
- Ring
- Star
A Bus topology is known for its simplicity and is commonly used for small local area networks.
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.
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.
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.
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.
In which routing protocol are areas a fundamental concept for designing a scalable and efficient network?
- BGP
- EIGRP
- OSPF
- RIP
OSPF (Open Shortest Path First) is a link-state routing protocol where areas are a fundamental concept for designing a scalable and efficient network.
How does MLPPP (Multilink Point-to-Point Protocol) differ fundamentally from standard PPP?
- It supports multiple logical links over a single physical connection.
- It uses a different encapsulation method.
- It is limited to synchronous communication.
- It only works over Ethernet connections.
MLPPP allows for the support of multiple logical links over a single physical connection, providing increased bandwidth and redundancy.
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 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.

- Star
A bus topology combines characteristics of linear bus and star topologies and is commonly used in wireless networks.
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.
