CCNA Networking Fundamentals Flashcards
Front | Back |
IP address for local loopback testing? | 127.0.0.1 |
Max host addresses in a /24 subnet? | 254 |
OSI model layer for data encryption? | Presentation layer |
Protocol for secure remote access? | SSH (Secure Shell) |
Purpose of a VLAN? | To segment a network logically without physical separation |
Function of a subnet mask? | Defines network and host portions of an IP |
Protocol to assign IP addresses dynamically? | DHCP (Dynamic Host Configuration Protocol) |
Protocol for email retrieval? | IMAP or POP3 |
Purpose of DHCP? | To automatically assign IP addresses |
Address type unique to each network device? | MAC address |
