Cisco Supporting Cisco Routing and Switching Network Devices Sample Questions (Q40-Q45):

NEW QUESTION # 40
Which type of memory stores the decompressed form of Cisco IOS Software and the running configuration?

A. flash
B. ROM
C. DRAM
D. NVRAM

Answer: C

Explanation:
The decompressed form of Cisco IOS Software and the running configuration are stored in DRAM (Dynamic Random-Access Memory) on Cisco devices. DRAM is used as the main memory for the device, where the operating system runs and the running configuration is stored. When a Cisco device boots up, the IOS image is decompressed and loaded into DRAM, and the running configuration is also held in this memory type. It's important to note that DRAM is volatile memory, which means its contents are lost when the device is powered off or restarted12.

NEW QUESTION # 41
Which command displays a list of file systems that are available on Cisco devices?

A. show memory
B. show directory
C. show version
D. show file system

Answer: D

Explanation:
The command show file system is used on Cisco devices to display a list of all the file systems available. This command provides information about each file system, including its name, size, free space, and file system type (such as flash or nvram). It's a useful command for network administrators to manage and navigate through different storage areas on Cisco devices, ensuring they can access and maintain the device's file structure effectively.

NEW QUESTION # 42
Which set of steps best describes how to assign a static IP address to the Ethernet port on a computer?

A. From the Network and Sharing Center, double-click Local Area Connection. Select Properties > iPass Protocol (IEEE 802.1x) > Properties > Static IP.
B. Click Start. Enter cmd and click OK. Enter the IP address XXX.XXX.XXX.XXX.
C. From the Network and Sharing Center, click Internet Protocol (TCP/IP), and follow the New Connection Wizard instructions.
D. From the Network and Sharing Center, click Change adapter, then double-click a local area connection. Select Internet Protocol (TCP/IP) > Properties > Use the Following Address, and then configure the IP information.

Answer: D

Explanation:
To assign a static IP address to the Ethernet port on a computer, particularly in a Windows environment, you would navigate to the Network and Sharing Center. From there, you would access the adapter settings, select your local area connection, and then enter the properties for Internet Protocol Version 4 (TCP/IPv4). Within the properties, you would choose the option to use a specific IP address and enter the desired IP information, including the IP address, subnet mask, and default gateway. This process sets a static IP address for the Ethernet port, ensuring that the computer will always use the same IP address every time it connects to the network, which is useful for various network configurations and applications.

NEW QUESTION # 44
What are two functions of SmartJack? (Choose two.)

A. It operates at Layer 2 of the OSI model.
B. It provides signal conversion.
C. It acts as a concentration point for dial-in and dial-out connections.
D. It provides channel testing.
E. It regenerates the signal to compensate for signal degradation from line transmission.

Answer: B,E

Explanation:
A SmartJack is a type of Network Interface Device (NID) that provides advanced features beyond simple electrical connection. Two of its functions include:
* Regenerating the signal: Similar to a repeater, a SmartJack can buffer and regenerate the signal to compensate for signal degradation that occurs during line transmission. This helps maintain signal integrity over longer distances1.
* Signal conversion: A SmartJack may also provide signal conversion, which involves converting codes and protocols to the type needed by the customer equipment. This can include converting framing types or other signal characteristics to ensure compatibility with the connected devices1.
The other options listed are not primary functions of a SmartJack:
* Operating at Layer 2 of the OSI model is not a function of a SmartJack; it is a characteristic of network devices like switches and bridges.
* Providing channel testing (D) is not a standard function of a SmartJack; however, SmartJacks enable phone companies to remotely test customer wiring without a site visit2.
* Acting as a concentration point for dial-in and dial-out connections (E) is not a function of a SmartJack; this is typically a function of devices like modems or access servers.
