A technician is unpacking a new Cisco Catalyst 2960-X switch. Which two items are typically included in the box with the switch itself? (Select TWO)
Show answer details
Correct answer: A, C
A standard AC power cord appropriate for the region of sale is always included.
Brackets and screws for mounting the switch in a standard 19-inch rack are included.

When a technician is working inside a router chassis, wearing an anti-static wrist strap is a critical safety procedure. To which point should the alligator clip of the wrist strap be connected to be most effective?
Show answer details
Correct answer: C
To safely dissipate any static electricity from your body, the wrist strap must be connected to a proper ground. The most reliable and accessible grounding point is an unpainted metal part of the chassis of the device you are working on. This ensures that you and the device are at the same electrical potential, preventing electrostatic discharge (ESD) that could damage sensitive electronic components. Painted surfaces are insulators and will not provide a proper ground.

A technician issues the
show versioncommand on a Cisco router. Which piece of information is found in the output of this command?Show answer details
Correct answer: B
The
show versioncommand provides a wealth of information, including the IOS version, system uptime, hardware details, and memory amounts. Crucially for boot process troubleshooting, the last line of the output displays the current configuration register value (e.g.,Configuration register is 0x2102). This value dictates how the router will boot. - 4
True or False: When opening a Priority 1 (P1) case with Cisco TAC for a production-down issue, it is acceptable to initiate the case via email.
Show answer details
Correct answer: B
This statement is false. According to Cisco's support policies, Priority 1 (Network Down) and Priority 2 (Severe Network Degradation) cases must be submitted via a live phone call to the Cisco Technical Assistance Center (TAC). This ensures the case is immediately routed to an available engineer for the fastest possible response time. Web and email case submission are reserved for lower-priority issues (P3 and P4).

A technician needs to connect a management laptop to the AUX port of a Cisco 2811 router for out-of-band management using a modem. What type of cable is required to connect the DB-9 port of the external modem to the RJ-45 AUX port on the router?
Show answer details
Correct answer: C
Both the Console and AUX ports on Cisco devices use a rollover pinout. To connect to a DTE device like a modem (which has a DB-9 serial port), a rollover cable is required. This is typically the same light blue cable used for console access, combined with a DB-9 adapter labeled 'Modem' to ensure the correct pins are matched for hardware flow control and signaling.

A field technician is dispatched to a remote office to replace a faulty HWIC-4ESW in a Cisco 2911 ISR. After physically installing the new card and powering on the router, the technician observes that the new switch ports are not recognized by the IOS. Which command should the technician use in privileged EXEC mode to verify that the router's hardware is physically detecting the new module?
Show answer details
Correct answer: B
The
show inventorycommand provides a detailed list of all physical hardware components detected by the router, including chassis, modules, cards (like HWICs), and SFPs. It will display the Product ID (PID) and Serial Number (SN) of the installed hardware. This is the correct command to confirm if the router's mainboard is physically recognizing the newly installed module, even before the IOS has configured interfaces for it. - 7
A technician is performing a password recovery on a Cisco Catalyst 3750 switch. After interrupting the boot process and issuing the
flash_initandload_helpercommands, the technician renames the configuration file. What is the next command required to proceed with booting the system into the setup wizard?Show answer details
Correct answer: C
After initializing the flash and renaming the configuration file (e.g.,
rename flash:config.text flash:config.bak), thebootcommand is used from theswitch:prompt (ROMMON) to continue the boot process. Since the originalconfig.textis not found, the switch will load without a configuration, allowing the technician to enter privileged EXEC mode and reset the password. - 8
A field technician needs to connect a laptop's serial port to the console port of a Cisco 2960 switch for initial configuration. The laptop does not have a native DB-9 serial port, so a USB-to-Serial adapter is being used. Which three settings are required to be configured in the terminal emulation software (e.g., PuTTY) to establish a successful console session? (Select THREE)
Show answer details
Correct answer: A, C, D
The default speed for a Cisco console port is 9600 bps.
The standard setting for data bits is 8.
The parity bit is not used and should be set to 'None'.

A technician is onsite to replace a customer's router. After completing the physical replacement and loading the configuration, the technician must document the work for the service ticket. According to standard professional service procedures, what is the most critical piece of information to record from the old, replaced device before it is shipped back for RMA?
Show answer details
Correct answer: B
The chassis serial number is the unique identifier for the physical hardware. It is absolutely essential for the Return Material Authorization (RMA) process. Cisco uses this number to track the faulty unit, validate the service contract, and process the return. Failure to record the correct serial number can lead to significant delays and complications in closing the service ticket and processing the RMA.

Case Study:
A regional bank, FinSecure, is upgrading its branch offices. A junior field technician is sent to a small branch to install a new Cisco ISR 4331 router. The work order specifies that the router must be configured with a basic setup to allow a senior engineer to access it remotely for final provisioning. The technician has console access but there is no existing network connectivity at the site yet.
The technician's task is to configure one of the Gigabit Ethernet interfaces (GigabitEthernet0/0/0) so the senior engineer can connect a laptop directly to it and access the router's command line via SSH. The senior engineer's laptop will be statically assigned the IP address 192.168.100.10/24.
Requirements:
- Configure the router's GigabitEthernet0/0/0 interface with the first usable IP address in the 192.168.100.0/24 network.
- Enable the interface.
- Set a hostname of
FS-Branch-4331. - Create a local user
remote_adminwith a privilege level of 15 and a secret passwordC1sc0!23. - Configure the VTY lines for SSH access only and use the local database for authentication.
- Generate RSA crypto keys of 1024 bits.
Which command is missing from the technician's configuration plan to meet all requirements?
Show answer details
Correct answer: C
To generate RSA keys for SSH, the
crypto key generate rsacommand requires two prerequisites: a hostname and an IP domain name. The case study mentions setting the hostname, but it does not mention setting an IP domain name. Without theip domain-namecommand being configured in global configuration mode, the RSA key generation will fail, and consequently, SSH access cannot be enabled. This is a critical and often overlooked step in the initial setup for SSH.
