Cisco Certified Technician R&S RSTECH (100-490) Training

Configure switches for remote management with a management ip on the vlan interface and a default gateway. Secure switch access with ssh, dhcp snooping, mac flooding and port security.

Configure basic switch settings across two interconnected switches by setting hostnames, enabling ssh, generating RSA keys, adding users, configuring ip domain name, and verifying with show commands and CDP.

Configure switch ports for access and trunk, create VLANs 3, 4, and 5, and enable port security on fast ethernet 0/12 with a 5 MAC limit and shutdown on violation.

Explore how VLANs segment a single switch into multiple logical networks, isolate broadcast traffic, and manage data, voice, and management VLANs with trunking and DTP concepts.

Learn how routers route data between networks, configure interfaces and IPv4/IPv6 addresses, and apply static and dynamic routing with default and floating routes, route summarization, and administrative distance.

Configure static routing across routers by assigning ip addresses to the zero zero, zero one, and zero two interfaces, then verify with show ip protocols and show ip route.

Learn how inter-VLAN routing enables communication between VLANs using router on a stick or layer 3 switching. Configure VLANs, subinterfaces, trunk links, and SVI gateways to route between VLANs.

Configure a lab for inter-vlan routing by setting up a switch with three VLANs, configuring access ports and a trunk, and creating router subinterfaces to verify PC connectivity.

Explore dynamic routing protocols that automatically update routing tables and handle topology changes, contrasting static routing with distance vector and link state approaches such as RIP, OSPF, ISIS, and BGP.

Explore Cisco access control lists, including standard and extended IPv4 and IPv6 ACLs, with permit and deny rules, wildcard masks, and inbound or outbound interface application.

Configure PC1 and PC2 with proper default gateways, then apply an extended ACL to block FTP, Telnet, and HTTP traffic from PC1 to PC2, with all other traffic permitted inbound.

Understand DHCP v4 to auto assign IP addresses and gateways via a server or router pool with exclusions, and compare IPv6 options including SLAAC, DHCPv6, and relay.

Explains how network address translation remaps private IP space to public IPs, conserving addresses and hiding inside local hosts, and covers static NAT, dynamic NAT, and port-based overload configurations.

Explore how to use CDP and LLDP to discover directly connected devices, configure NTP for clock synchronization, and perform the password recovery process for routers and switches.

Learn cybersecurity basics, its core principles, and how to identify threats like phishing, malware, ransomware, and social engineering to secure networks and data.

Explore core principles of cybersecurity, including CIA triad of confidentiality, integrity, and availability, plus AAA authentication, authorization, and accounting. Learn defenses in depth, non-repudiation, and least privilege.
