- User interfaces and network services
The primary function of the Application Layer in the OSI model is to provide user interfaces and network services.
How does Dynamic PAT (Port Address Translation) handle IP address translation for a large number of internal hosts?
- It assigns a unique public IP address to each internal host.
- It dynamically assigns unique port numbers to each internal host sharing a single public IP address.
- It relies on static port assignments for each internal host.
- It uses multiple public IP addresses in a one-to-one mapping with internal hosts.
Dynamic PAT handles IP address translation for a large number of internal hosts by dynamically assigning unique port numbers to each internal host sharing a single public IP address.
An organization wants to automate their network configurations and ensure state consistency across devices. Which automation tool should they implement?
- Ansible
- Puppet
- Chef
- SaltStack
Ansible is a popular automation tool for network configuration management, providing simplicity and ensuring state consistency across devices.
A network engineer is configuring a high-availability network with Cisco routers. They need a protocol that offers both redundancy and load balancing for multiple routers acting as a gateway. Which protocol is most appropriate?
- HSRP (Hot Standby Router Protocol)
- VRRP (Virtual Router Redundancy Protocol)
- GLBP (Gateway Load Balancing Protocol)
- OSPF (Open Shortest Path First)
GLBP is a Cisco proprietary protocol that provides both redundancy and load balancing for multiple routers acting as a gateway in a high-availability network.
An organization needs to securely connect its main office to three regional offices using the internet. What is the most appropriate solution to ensure security and connectivity?
- MPLS (Multiprotocol Label Switching)
- VLAN (Virtual Local Area Network)
- SD-WAN (Software-Defined Wide Area Network)
- OSPF (Open Shortest Path First)
SD-WAN is designed for secure and efficient connectivity over the internet, making it a suitable solution for connecting multiple offices securely.
An organization requires a firewall solution that can manage and monitor both internal and external traffic efficiently. What type of firewall should they consider?
- Stateful Inspection
- Proxy Firewall
- Next-Generation Firewall (NGFW)
- Packet Filtering
A Next-Generation Firewall (NGFW) is designed to manage and monitor both internal and external traffic efficiently with advanced features beyond traditional firewalls.
A network administrator is designing a system with a focus on redundancy and minimal downtime. What network technology should they prioritize?
- Dynamic Host Configuration Protocol (DHCP)
- Network Address Translation (NAT)
- Simple Network Management Protocol (SNMP)
- Virtual Router Redundancy Protocol (VRRP)
To prioritize redundancy and minimal downtime, the network administrator should prioritize Virtual Router Redundancy Protocol (VRRP), which provides high availability by allowing for a backup router to take over in case the primary router fails.
