200-301 V1 Ch06: Switch Management
Config Lab: Switch Duplex and Speed
For this next lab, instead of just asking you what the IEEE auto-negotiation rules look like, the lab asks you to configure some switches in ways that affect auto-negotiation. But the lab gives you the end goal: the resulting speed
Config Lab: Telnet Config
Today’s post takes us from a cleanly wiped router config (except hostnames), to one router being ready for Telnet support. As usual, you can do the lab on paper or in a text editor in just a few minutes, or
Config Lab: CLI Miscellany 1
The CCNA certification includes many prominent features that need to be configured. VLANs. Trunking. Routing protocols. IPv4 addressing. IPv6 addressing. But there are also the occasional small topic or single command that might be forgotten. This lab examines a couple
Config Lab: Login Security 1
One of the first configuration items that become second nature is the configuration of basic password settings. But it is also easy to forget about the small differences in password security configuration once you get used to configuring your own
Config Lab: Switch IP 1
A layer 2 switch does not need an IP address or default gateway for its primary purpose of forwarding layer 2 Ethernet frames. However, the switch does need an IP address and a default gateway for layer 3 communication, such
Config Lab: Enabling SSH and Disabling Telnet
Many of us start out learning about the simplest Cisco security option: One password for all users to reach user mode, with no per-user login. By today’s standards, that security method is archaic. Today’s lab lets you upgrade from that
Config Lab: CLI Passwords 2
The simplest way to protect the CLI uses passwords shared by all, rather than a per-user username and password. Using a per-user login method improves security. The easiest option for using per-user logins in a Cisco lab is configuring the
Config Lab: CLI Passwords 1
Protecting access to the CLI of Cisco routers and switches starts with basic password security. From there, you can move on to use per-user login security that requires both a username and password, whether using locally-configured username/password pairs or whether
Answer: Forwarding and Encapsulation
The #CCNA exam can pack a punch with what looks like a simple question, and this latest practice question is just such an example. The question asks about switch forwarding, but it combines packet encapsulation concepts. Get either wrong, and
