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.
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.
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.
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 designing a network with a focus on security and efficient routing, which IP version's features would be most beneficial?
- IPX
- IPv4
- IPv5
- IPv6
IPv6 incorporates features that enhance security and efficient routing, making it beneficial for networks with these design considerations.
In terms of device monitoring, what is the main function of a Syslog server?
- Backs up device configurations
- Encrypts network traffic
- Provides real-time alerts and logs
- Manages IP addressing
A Syslog server's main function in device monitoring is to provide real-time alerts and logs, offering insights into the health and activities of network devices.
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.
