SRWE MODULE 1: BASIC DEVICE CONFIGURATION | COMPLETE PRACTICE
QUESTIONS, ANSWERS & STUDY GUIDE 2026/2027
Describe the 5-step boot sequence of of a Cisco switch. - ANS ✔✔1) Switch loads the POST (power-on
self-test) program from ROM, to check the subsystem (incl. CPU, DRAM, and portion of the flash device
that makes up the flash file system
2) Switch loads the boot loader (small software from ROM)
3) Boot loader does low-level initializations, to initialize CPU registers (controls memory location,
quantity, and speed)
4) Boot loader initializes the flash file system on the system board
5) Boot loader locates and loads the default IOS OS system software image into memory AND gives
control of switch to the IOS
Which command do you use to Examine the Cisco IOS version information of a switch? - ANS ✔✔- "show
version"
Which command do you use to examine the properties of an interface? - ANS ✔✔- "show interface"
OR
- "show interface ___" (ex. show interface gig1/0/6"
Which command(s) do you use to examine the contents of the flash directory? - ANS ✔✔- "show flash:"
OR
- "dir flash:"
Which command do you use to see which ports are associated with each VLAN on a switch? - ANS ✔✔-
"show vlan brief"
Which command do you use to prevent console messages from interrupting commands? - ANS ✔✔-
once in the config mode for a specific interface, use the "logging synchronous" command
Which command do you use to examine the IP properties (aka Layer 3 properties) of a VLAN? - ANS ✔✔-
"show ip interface _____" (ex. show up interface vlan1)
Which command do you use to see the Layer 1 and Layer 2 characteristics of a switch interface? - ANS
✔✔- "show interface _____" (ex. "show interface vlan1"
Why do you set a default gateway on a switch? - ANS ✔✔- to be able to manage the switch from a
remote network more than one router away
