The five questions
1. Refer to the exhibit. A technician reads a transceiver's status before installing it. Based on the part number, what type of link does this optic support?
- A. 10G long-reach over single-mode fiber
- B. 1G copper over Cat6
- C. 10G short-reach over multimode fiber
- D. 40G over a QSFP module
Correct answer: C.
The part number SFP-10G-SR designates a 10 Gigabit short-reach optic operating at 850 nm over multimode fiber, so the SR suffix and wavelength confirm a short-distance multimode link.
Why the others are wrong. A long-reach 10G optic over single-mode would be labeled LR, not SR. A 1G copper module would not read 10G or show an optical wavelength. A 40G QSFP is a different form factor, not an SFP.
2. Refer to the exhibit. Before returning a failed router under RMA, which two identifiers should the technician record from the show version output? (Choose two.)
- A. The processor board ID (serial number)
- B. The IOS XE version string
- C. The console baud rate
- D. The model number ISR4331/K9
- E. The configuration register value
Correct answer: A.
For an RMA Cisco needs to identify the exact physical unit and its model, so the technician records the processor board ID, which is the chassis serial number, and the model number ISR4331/K9 shown in the output.
Why the others are wrong. The IOS XE version identifies software, not the hardware being returned. The console baud rate is a terminal setting unrelated to hardware identity. The configuration register controls boot behavior and is not required to process a hardware return authorization.
3. A field technician reviews the OSI reference model while troubleshooting. Starting from the top and counting down, which layer sits at Layer 1 of the model?
- A. Application
- B. Physical
- C. Transport
- D. Data Link
Correct answer: B.
Layer 1 is the Physical layer, which defines the electrical, optical, and mechanical signaling that moves raw bits across the medium, including cables, connectors, and transceivers.
Why the others are wrong. Application is Layer 7 at the top of the stack where user protocols run. Transport is Layer 4, handling end-to-end delivery. Data Link is Layer 2, which frames bits for the local link but sits one layer above Physical.
4. A field technician powers on a Cisco router and watches the console. In the normal boot sequence, what runs first before any software is loaded?
- A. The bootstrap loads the IOS image from flash
- B. The startup-config is copied from NVRAM to RAM
- C. The power-on self-test (POST) checks the hardware
- D. The configuration register value is rewritten
Correct answer: C.
POST is the first step: the ROM-based power-on self-test verifies the CPU, memory, and interface hardware before the bootstrap loads any software or configuration. It must pass before the boot can continue.
Why the others are wrong. The bootstrap loading IOS from flash and copying the startup-config from NVRAM both happen later, after POST completes and the bootstrap runs. The configuration register is read during boot, not rewritten automatically; the technician changes it manually.
5. On a device running in install mode, a technician lists flash and sees a file named packages.conf. What role does this file serve?
- A. It stores the saved startup configuration
- B. It is a backup copy of the full IOS bundle image
- C. It is a licensing file required by Smart Licensing
- D. It lists the software packages the device loads at boot
Correct answer: D.
In install mode the packages.conf provisioning file references the individual .pkg files, and the device reads it at boot to know which software packages to load. It is central to how install mode operates on the platform.
Why the others are wrong. The startup configuration lives in NVRAM as startup-config, not in packages.conf. A bundle image is a single monolithic .bin file, which is what install mode expands rather than a backup of. Licensing files are handled by Smart Licensing and are unrelated to this provisioning file.
6. A technician sees lightweight access points at a site that all depend on one central appliance for their configuration and management. Which Cisco device fills that role?
- A. An integrated services router
- B. An adaptive security appliance
- C. A Catalyst access switch
- D. A wireless LAN controller
Correct answer: D.
A wireless LAN controller centrally manages lightweight access points, pushing their configuration and handling client traffic, so the access points depend on it to operate. That central control role is exactly what the scenario describes.
Why the others are wrong. An integrated services router forwards packets between networks and terminates WAN links, not manage APs. An adaptive security appliance is a firewall enforcing security policy at the perimeter. A Catalyst access switch provides wired ports for endpoints and does not centrally control lightweight access points.
7. A field technician is about to handle a spare supervisor module. What is the main reason for wearing a properly grounded anti-static wrist strap while handling it?
- A. It shields the module from electromagnetic interference nearby
- B. It prevents the technician from receiving an electric shock
- C. It clamps the module firmly to the workbench surface
- D. It safely drains static charge from the technician to ground
Correct answer: D.
A grounded wrist strap equalizes the technician's body potential with ground and continuously bleeds off static charge, so a sudden electrostatic discharge cannot pass through and damage sensitive components on the module.
Why the others are wrong. Electromagnetic shielding is a function of the chassis and cabling, not the strap. The strap is not a shock-protection device and must never be worn when working on live power. It does not physically secure the module to anything either.
8. During encapsulation, data is handed down the stack and each layer adds its header. What is the protocol data unit at the Transport layer called?
- A. Segment
- B. Frame
- C. Packet
- D. Bit
Correct answer: A.
At the Transport layer, the protocol data unit is called a segment, produced when TCP or UDP breaks application data into pieces and adds a transport header with port numbers.
Why the others are wrong. A frame is the Data Link PDU, a packet is the Network layer PDU, and a bit is the Physical layer PDU. Each belongs to a different layer, so none is the Transport layer unit.
