It establishes and manages secure VPN connections It ensures high availability by distributing traffic across multiple servers It filters out malicious network traffic It provides dynamic IP addressing for remote devices 4 / 25 Which appliance would a network administrator use to provide centralized storage that can be accessed by devices over the network? NAS SAN Firewall Router 5 / 25 Which type of network appliance is specifically designed to handle requests from clients over the internet, ensuring that content is delivered as efficiently as possible? Load balancer Content Delivery Network (CDN) VPN concentrator Wireless access point 6 / 25 Which of the following devices is typically used to filter web traffic, cache content, and monitor access to websites? Proxy server DNS server IDS/IPS NAS device 7 / 25 A network administrator wants to provide high availability for a web application by distributing traffic across multiple servers. Which appliance should they implement? Proxy server Load balancer Router VPN concentrator 8 / 25 What is the primary purpose of a proxy server in a network? To provide secure communication for remote users To cache web content and reduce the load on external servers To monitor and log all network traffic for auditing purposes To assign IP addresses to clients on the network 9 / 25 Which of the following network devices can act as both an IDS and an IPS, providing different functionalities based on configuration? Firewall Load Balancer Router Intrusion Detection/Prevention System (IDS/IPS) 10 / 25 What is a key difference between a router and a switch in terms of network operation? A router connects devices within the same subnet, while a switch connects devices between different subnets A router operates at Layer 3 (Network), while a switch operates at Layer 2 (Data Link) A router handles wireless communication, while a switch only manages wired communication A router is responsible for providing IP addresses, while a switch only manages MAC addresses 11 / 25 Which of the following is the most accurate description of the role of a router in managing a network? It filters traffic between subnets and ensures data is routed based on IP addresses It ensures data packets are properly formatted for transmission over the physical medium It stores and forwards data between devices within the same network segment It secures a network by monitoring for suspicious traffic and preventing unauthorized access 12 / 25 What is the purpose of Time to Live (TTL) in an IP packet? To limit the number of hops an IP packet can make before being discarded To track how long a packet has been in transit for performance analysis To specify how long a connection is allowed to remain open To store the expiration date of a packet's contents 13 / 25 Which of the following network functions is responsible for prioritizing certain types of traffic to ensure that critical applications receive the necessary bandwidth? VPN Quality of Service (QoS) Time to Live (TTL) Load balancing 14 / 25 A Virtual Private Network (VPN) is primarily used to: Encrypt traffic between devices on the same local network Securely connect remote users or sites to a network over a public internet connection Provide high availability by distributing traffic across multiple servers Filter web traffic to block unauthorized content 15 / 25 What does a Content Delivery Network (CDN) do to improve web application performance? It encrypts website traffic to protect user data It stores frequently accessed data closer to users to reduce latency and improve loading times It routes traffic based on QoS parameters to ensure the best experience for all users It filters web traffic for malicious content and viruses 16 / 25 Which network appliance is responsible for managing multiple wireless access points (APs) within a network Wireless access point (AP) Wireless controller Switch Router 17 / 25 What is the primary function of a wireless access point (AP) in a network? It converts data from one wireless standard to another It provides wireless connectivity to devices within a specified area, connecting them to the wired network It encrypts wireless communications to ensure secure data transmission It manages all wireless devices in the network, ensuring their security and connectivity 18 / 25 Which of the following best describes the function of a Storage Area Network (SAN)? It stores files and data that can be accessed by users across the network It provides block-level storage that can be used by servers as though it were a local disk It stores backups and archives of files on a remote server It optimizes storage for virtual machines in cloud environments 19 / 25 What type of network storage device is designed to provide centralized storage that is directly accessible by network users? Network Attached Storage (NAS) Storage Area Network (SAN) Load balancer Proxy server 20 / 25 Which of the following best describes the role of a proxy server in a network? It assigns IP addresses to network devices dynamically It filters web traffic, caches content, and acts as an intermediary between clients and servers It ensures network security by blocking unauthorized access to internal systems It connects devices across multiple subnets by routing traffic based on IP addresses 21 / 25 What is the primary function of a load balancer in a network? It encrypts traffic between remote users and the internal network It distributes incoming network traffic across multiple servers to optimize resource use It ensures network traffic is routed based on the shortest path algorithm It prevents unauthorized access to sensitive data by filtering incoming traffic 22 / 25 What is the primary difference between an Intrusion Detection System (IDS) and an Intrusion Prevention System (IPS)? An IDS monitors network traffic and generates alerts, while an IPS actively blocks malicious traffic An IDS operates only on wireless networks, while an IPS works on wired networks An IDS only detects threats on Layer 3, while an IPS can detect threats on Layer 7 An IDS is only used to monitor applications, while an IPS works at the network layer 23 / 25 Which of the following statements best describes the role of a firewall in a network? It forwards traffic between different VLANs It encrypts communications to protect data confidentiality It filters incoming and outgoing traffic based on security policies It assigns IP addresses dynamically to devices on the network 24 / 25 A switch operates primarily at which OSI layer, and what is its primary function? Layer 2 (Data Link); it forwards packets based on MAC addresses Layer 3 (Network); it forwards packets based on IP addresses Layer 4 (Transport); it prioritizes traffic based on QoS Layer 7 (Application); it analyzes application traffic for security threats 25 / 25 What is the primary function of a router in a network? To segment a network and forward frames between devices on the same local network To forward data packets between different networks based on IP addresses To provide centralized storage that can be accessed over the network To store and forward email messages between servers Your score is 0% Restart quiz
