An organization wants to block all incoming traffic from a specific IP range due to security concerns. Which feature of ACLs would be most effective?
- Dynamic ACL
- Named ACL
- Reflexive ACL
- Standard ACL
Standard ACLs can filter traffic based on source IP addresses, making them effective for blocking specific IP ranges.
What is the purpose of subnetting in IPv4 networks?
- To improve network security
- To increase the number of available IP addresses
- To provide a way to group hosts logically and efficiently
- To reduce network congestion
Subnetting in IPv4 networks serves the purpose of logically grouping hosts to optimize network management and improve efficiency.
How does route summarization impact the convergence time in a dynamic routing environment?
- Accelerates convergence
- Delays convergence
- Has no impact on convergence
- Improves route computation
Route summarization can potentially delay convergence in a dynamic routing environment by limiting the exchange of detailed route information between routers.
What is the primary function of Border Gateway Protocol (BGP) in networking?
- Dynamic Routing
- Interior Gateway Protocol (IGP)
- Exterior Gateway Protocol (EGP)
- Link-State Routing
The primary function of Border Gateway Protocol (BGP) is to exchange routing information between different Autonomous Systems (AS) on the Internet, making it an Exterior Gateway Protocol (EGP).
________ encryption is commonly used in SSH for securing remote management sessions.
- Symmetric
- Asymmetric
- Public Key
- Private Key
Asymmetric encryption is commonly used in SSH for securing remote management sessions.
What is the primary purpose of the Spanning Tree Protocol (STP) in a network?
- Error detection
- Load balancing
- Preventing loops
- Reducing latency
The primary purpose of the Spanning Tree Protocol (STP) is to prevent loops in a network topology, ensuring a loop-free and stable network.
In DHCP, what is the purpose of the lease time?
- To specify the client's hardware address
- To determine the subnet mask
- To define the period a client can use an IP address
- To assign a default gateway
The lease time in DHCP defines the period during which a client can use the assigned IP address before renewal is required.
How does dynamic routing differ from static routing in terms of scalability in a growing network?
- Both dynamic and static routing have similar scalability in a growing network.
- Dynamic routing is more scalable as it adapts to changes in the network, while static routing becomes impractical in a large and dynamic environment.
- Scalability is not a consideration in routing protocols.
- Static routing is more scalable as it allows for easy management of routes, while dynamic routing may become complex and less scalable as the network grows.
Dynamic routing is more scalable in a growing network as it can adapt to changes, making it suitable for larger and dynamic environments.
________ is a secure alternative to Telnet for accessing command-line interfaces on network devices.
- SSH
- SNMP
- SMTP
- HTTPS
SSH (Secure Shell) is a secure alternative to Telnet for accessing command-line interfaces on network devices.
In setting up a small office network, which device would be the most cost-effective for connecting multiple PCs while ensuring basic connectivity?
- Bridge
- Hub
- Router
- Switch
A hub is the most cost-effective device for connecting multiple PCs in a small office network, ensuring basic connectivity without advanced features.
