Which two features describe controller-based networking solutions compared to traditional networking solutions? (Choose two.)

  1. inflate licensing costs
  2. reduce network configuration complexity
  3. provide centralization of primary IT functions
  4. allow for fewer network failures
  5. increase network bandwidth usage

Answer(s): B,C

Explanation:

-B. Reduce network configuration complexity: Controller-based networking solutions centralize the configuration of the network, which can make it easier to manage and maintain the network.
-C. Provide centralization of primary IT functions: Controller-based networking solutions can centralize other IT functions, such as security and policy management. This can improve efficiency and reduce the risk of errors.

The other options are not as accurate descriptions of controller-based networking solutions.

-Inflate licensing costs: Controller-based networking solutions may require additional licensing costs, but this is not always the case.
-D. Allow for fewer network failures: Controller-based networking solutions can help to reduce network failures by providing a centralized view of the network and by making it easier to troubleshoot problems. However, they do not guarantee that there will be no network failures.
-E. Increase network bandwidth usage: Controller-based networking solutions do not necessarily increase network bandwidth usage. In fact, they can help to improve network performance by optimizing traffic flows.

Which two characteristics are associated with 802.1s? (Choose two.)

  1. 802.1s provides for faster convergence over 802.1D and PVST+
  2. 802.1s is a Cisco enhancement to 802.1w
  3. 802.1s supports up to 1024 instances of 802.1w
  4. 802.1s maps multiple VLANs to the same spanning-tree instance
  5. CPU and memory requirements are the highest of all spanning-tree STP implementations

Answer(s): A,D

Explanation:

-802.1s provides for faster convergence over 802.1D and PVST+: 802.1s uses a rapid convergence algorithm that is based on the Optimized Spanning Tree Protocol (RSTP). This algorithm allows 802.1s to converge much faster than 802.1D or PVST+.
-D. 802.1s maps multiple VLANs to the same spanning-tree instance: 802.1s allows multiple VLANs to be mapped to the same spanning-tree instance. This is known as Multiple Spanning Tree (MST). MST can improve network performance by reducing the number of spanning-tree instances that need to be maintained.
The other options are incorrect.

-B. 802.1s is a Cisco enhancement to 802.1w: 802.1s is an IEEE standard, not a Cisco enhancement.
-C. 802.1s supports up to 1024 instances of 802.1w: 802.1s supports up to 1024 MST instances. Each MST instance can support up to 4096 VLANs.
-E. CPU and memory requirements are the highest of all spanning-tree STP implementations: The CPU and memory requirements of 802.1s are comparable to other STP implementations.

What are two advantages of controller-based networks versus traditional networks? (Choose two.)

  1. more consistent device configuration
  2. the ability to have forwarding tables at each device
  3. programmatic APIs that are available per device
  4. the ability to configure the features for the network rather than per device
  5. more flexible configuration per device

Answer(s): A,D

Explanation:

-More consistent device configuration: Controller-based networks centralize the configuration of the network, which can make it easier to manage and maintain the network. This can also help to ensure that all devices are configured identically, which can improve security and reliability.
-D. The ability to configure the features for the network rather than per device: Controller-based networks allow you to configure features for the network as a whole, rather than per device. This can make it easier to manage and maintain the network, and it can also help to improve performance.
The other options are not as accurate descriptions of the advantages of controller-based networks.

-B. The ability to have forwarding tables at each device: This is a feature of traditional networks, not controller-based networks.
-C. Programmatic APIs that are available per device: This is a feature of both controller-based networks and traditional networks.
-E. More flexible configuration per device: Controller-based networks can be more flexible than traditional networks, but they can also be less flexible. It depends on the specific implementation.

What are two design constraints in a standard spine and leaf architecture? (Choose two.)

  1. Spine switches can connect to each other
  2. Endpoints connect only to the spine switches
  3. Each spine switch must connect to every leaf switch
  4. Leaf switches must connect to each other
  5. Each leaf switch must connect to every spine switch

Answer(s): B,E

Explanation:

Endpoints connect only to the spine switches: In a standard spine and leaf architecture, endpoints such as servers or storage devices connect only to the spine switches, and not directly to the leaf switches. This is because the spine switches act as the core of the network, providing high-speed connectivity and traffic aggregation.
