Correct Option: D

As a frame travels through a routed network the Mac address will always:

  1. the source address will change and the destination address will change

  2. change to reflect the current source and destination

  3. remain the same

  4. the source address will remain the same but the destination address will change

  5. none of the above


Correct Option: B
Explanation:

To solve this question, the user needs to know about MAC addresses and how they work in a routed network.

MAC addresses are unique identifiers assigned to network interfaces by the manufacturer. Each MAC address is assigned to a specific device, and it is used to identify that device on a network.

In a routed network, packets are sent from one network to another through intermediate devices such as routers. As a packet travels through the network, the MAC address of the source and destination will change depending on the device it is passing through.

Now let's go through each option and explain why it is right or wrong:

A. The source address will change and the destination address will change: This option is incorrect because the source and destination MAC addresses will not always change. They may change as the packet passes through different devices in the network, but they may also remain the same in certain cases.

B. Change to reflect the current source and destination: This option is partially correct. The MAC address of the packet will change as it passes through different devices in the network. However, it is not changing to reflect the current source and destination, but rather to identify the device the packet is currently passing through.

C. Remain the same: This option is incorrect. While it is possible for the MAC address to remain the same in certain cases, it is not always the case.

D. The source address will remain the same but the destination address will change: This option is also partially correct. The source MAC address will not change, but the destination MAC address will change as the packet passes through different devices in the network.

E. None of the above: This option is incorrect because options B and D are partially correct.

Therefore, the correct answer is:

The Answer is: B or D (both are partially correct)

  1. The source of commonly used configuration commands

  2. The primary source of the Cisco IOS

  3. A location to run the active configuration from

  4. A location to run the power on diagnostics from

  5. A location to store a backup copy of the router configuration file


Correct Option: E

Under what conditions will a router enter setup mode?

  1. By manually entering setup mode from the system load prompt

  2. By manually entering setup mode from the configuration load prompt

  3. If no configuration file can be found

  4. If the present configuration file is older than the one attempting to load

  5. By manually entering setup mode from the user prompt


Correct Option: C

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) By manually entering setup mode from the system load prompt - This option is incorrect because entering setup mode from the system load prompt is not a condition for a router to enter setup mode. Setup mode is typically entered by using the "setup" command.

Option B) By manually entering setup mode from the configuration load prompt - This option is incorrect because entering setup mode from the configuration load prompt is not a condition for a router to enter setup mode. Setup mode is typically entered by using the "setup" command.

Option C) If no configuration file can be found - This option is correct. If a router cannot find a valid configuration file during the startup process, it will automatically enter setup mode to allow for initial configuration.

Option D) If the present configuration file is older than the one attempting to load - This option is incorrect. The age of the configuration file does not determine whether a router enters setup mode or not.

Option E) By manually entering setup mode from the user prompt - This option is incorrect because entering setup mode from the user prompt is not a condition for a router to enter setup mode. Setup mode is typically entered by using the "setup" command.

The correct answer is C) If no configuration file can be found. This option is correct because when a router cannot find a valid configuration file during the startup process, it will automatically enter setup mode to allow for initial configuration.

  2. NVRAM, TFTP Server, RAM

  3. TFTP Server, FTP Server, ROM

  4. Flash memory, TFTP Server, ROM

  5. NVRAM, Flash memory


Correct Option: D

AI Explanation

To answer this question, we need to understand the possible locations from which the operating system can be loaded at system initialization.

Option A) NVRAM, TFTP Server, ROM - This option is incorrect because it does not include Flash memory as a possible location.

Option B) NVRAM, TFTP Server, RAM - This option is incorrect because it does not include Flash memory as a possible location.

Option C) TFTP Server, FTP Server, ROM - This option is incorrect because it does not include Flash memory or NVRAM as possible locations.

Option D) Flash memory, TFTP Server, ROM - This option is correct. The operating system can be loaded from Flash memory, which is a non-volatile memory that retains data even when power is removed. It can also be loaded from a TFTP (Trivial File Transfer Protocol) Server, which allows for remote loading of files. ROM (Read-Only Memory) is also a possible location.

Option E) NVRAM, Flash memory - This option is incorrect because it does not include ROM or TFTP Server as possible locations.

The correct answer is D. This option includes all the possible locations from which the operating system can be loaded at system initialization: Flash memory, TFTP Server, and ROM.

Which of the following statements is/are true about metrics used in routing protocols?

  1. A metric is the administrative distance of a routing protocol.

  2. A metric is a measure of trustworthiness and availability of a route.

  3. Both of the above

  4. none of the above


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of metrics in routing protocols.

Option A) A metric is the administrative distance of a routing protocol - This option is incorrect. The administrative distance is a concept used in routing to determine the preferability of routes from different routing protocols. It is not the same as a metric, which is a value used to measure the desirability of a route.

Option B) A metric is a measure of trustworthiness and availability of a route - This option is correct. In routing protocols, a metric is a value assigned to a route to represent its desirability. It can be based on various factors such as bandwidth, delay, reliability, or cost. A lower metric typically indicates a more preferred route.

Option C) Both of the above - This option is incorrect. Option A is incorrect, as explained above.

Option D) None of the above - This option is incorrect. Option B is correct, as explained above.

The correct answer is B. This option is correct because a metric in routing protocols is a measure of trustworthiness and availability of a route.

  1. 1000

  2. 2600

  3. 2500

  4. 7500

  5. none of the above


Correct Option: D

AI Explanation

To answer this question, you need to understand the different router series and how they address their port numbers.

Option A) 1000 - This option is incorrect because the 1000 router series does not require the port numbers to be addressed in the format of slot/adapter/port number.

Option B) 2600 - This option is incorrect because the 2600 router series does not require the port numbers to be addressed in the format of slot/adapter/port number.

Option C) 2500 - This option is incorrect because the 2500 router series does not require the port numbers to be addressed in the format of slot/adapter/port number.

Option D) 7500 - This option is correct because the 7500 router series does need its port numbers to be addressed in the format of slot/adapter/port number. In this series, the port numbers are specified using the format of slot/adapter/port number.

Option E) none of the above - This option is incorrect because the correct answer is D, the 7500 router series.

The correct answer is D. The 7500 router series needs its port numbers to be addressed in the format of slot/adapter/port number.

The process of address learning will happen in a switch only after the initial flooding of frames.

  1. True

  2. False


Correct Option: A

AI Explanation

To answer this question, we need to understand the process of address learning in a switch.

Address learning is the process by which a switch learns and associates MAC addresses with specific ports. When a switch receives a frame, it examines the source MAC address of the frame and associates it with the port from which the frame was received. This allows the switch to build a MAC address table, also known as a forwarding table or content-addressable memory (CAM) table.

Now, let's evaluate the given statement:

The process of address learning will happen in a switch only after the initial flooding of frames.

Option A) True - This option is correct. When a switch initially receives a frame, it does not know the location of the destination MAC address. Therefore, it floods the frame out of all ports, except the one it was received on. This flooding allows the switch to learn the source MAC addresses and associate them with the respective ports. After this initial flooding, the switch can perform address learning and update its MAC address table.

Option B) False - This option is incorrect. The address learning process in a switch occurs after the initial flooding of frames.

Therefore, the correct answer is A) True. This option is correct because the address learning process in a switch occurs only after the initial flooding of frames.

_______________ transparency is a primary advantage of both bridging and switching.

  1. Encryption

  2. Upper layer protocol

  3. Lower Layer protocol

  4. none of the above


Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of transparency in networking.

Transparency refers to the ability of a networking technology to operate without the need for the user or application to have knowledge of its underlying details. In other words, it allows for seamless communication between different devices or networks without requiring any specific configuration or intervention.

Both bridging and switching are networking technologies that provide transparency. They operate at the data link layer (Layer 2) of the OSI model and are responsible for forwarding data packets within a local area network (LAN).

Option A) Encryption - Encryption is a security mechanism used to protect data by converting it into a form that cannot be easily understood by unauthorized users. While encryption can be used in conjunction with bridging and switching, it is not directly related to the transparency aspect.

Option B) Upper layer protocol - This option is the correct answer. Upper layer protocols, such as TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), are responsible for providing services and functionality at higher layers of the OSI model (Layers 4 to 7). While upper layer protocols are not directly related to the operation of bridging and switching, their transparency is a primary advantage because they can seamlessly communicate with different devices or networks without requiring specific knowledge or configuration.

Option C) Lower Layer protocol - Lower layer protocols, such as Ethernet and Wi-Fi, operate at the physical and data link layers (Layers 1 and 2) of the OSI model. While lower layer protocols are involved in the operation of bridging and switching, they are not the primary advantage in terms of transparency.

Option D) None of the above - This option is incorrect because the correct answer is Option B.

Therefore, the correct answer is B) Upper layer protocol. This option is correct because the transparency provided by bridging and switching allows upper layer protocols to seamlessly communicate without requiring specific knowledge or configuration.
