Cisco 200-901 Online Questions & Answers

• Question 11:

  What is the purpose of grouping devices in a VLAN?

  A. Devices communicate as if they are connected on the same wire.
  B. Multicast network traffic is limited to the VLAN connected devices.
  C. Unicast messages are limited to the clients connected on the same VLAN.
  D. Network traffic is load balanced between the devices connected to the VLAN.
  A. Devices communicate as if they are connected on the same wire.

  ---

  When devices are grouped into a VLAN, they can communicate as if they are connected on the same wire, even if they are physically located on different parts of the network. This can be useful for reducing the number of physical cables needed and for improving network performance. However, there are other purposes for grouping devices in a VLAN as well, such as limiting multicast network traffic to the VLAN connected devices and controlling which devices can communicate with each other.

• Question 12:

  Which action resolves a 401 error in response to an HTTP GET that is issued to retrieve a configuration statement using RESTCONF on a CSR 1000V?

  A. Change the HTTP method to PUT.
  B. Check the MIME types in the HTTP headers.
  C. Change the transport protocol to HTTPS.
  D. Check the authentication credentials.
  D. Check the authentication credentials.

  ---

  Explanation Explanation/Reference:The 401 (Unauthorized) status code indicates that the request has not been applied because it lacks valid authentication credentials for the target resource.

• Question 13:

  Which action does the Git command git merge allow the developer to perform?

  A. Combine multiple sequences of commits into one unified history
  B. Push changes to the remote repository
  C. Create, list, rename, and delete branches
  D. Switch between branches
  A. Combine multiple sequences of commits into one unified history

  ---

  Explanation Explanation/Reference:Git merge will combine multiple sequences of commits into one unified history. In the most frequent use cases, git merge is used to combine two branches. Reference: https://www.atlassian.com/git/tutorials/using-branches/git-merge

• Question 14:

  DRAG DROP

  Drag and drop the code from the bottom onto the box where the code is missing to retrieve the RESTCONF running configuration for an interface named TwentyFiveGigabitEthernet 1/1/2. Not all options are used.

• Question 17:

  A customer's cloud services must:

  1.

  Migrate services to another data center on demand.

  2.

  Save the operational state of the machine on demand.

  3.

  Support Windows and Linux GUIs.

  4.

  Maximize hardware utilization.

  Which type of deployment meets these requirements?

  A. bare metal
  B. container
  C. virtual machine
  D. Kubernetes
  C. virtual machine

  ---

  Virtual machines (VMs) provide the flexibility and capabilities required to meet the described requirements. VMs can easily migrate between data centers, save and restore their state, and support various operating systems and GUIs. Migration: VMs can be moved from one physical server or data center to another, providing high flexibility in resource management. State Saving: VMs support saving the operational state (snapshots), allowing quick recovery or migration. Support for GUIs: VMs can run different operating systems, including those with graphical user interfaces (GUIs) like Windows and Linux. Hardware Utilization: VMs enable better utilization of hardware resources by running multiple VMs on a single physical host. References: Virtual Machines Overview: VMware VMs

• Question 18:

  When changes are made to the same file across two branches, which git status is shown when the branches are combined?

  A. unmerged
  B. uncommitted
  C. conflict
  D. branched
  C. conflict

• Question 19:

  Which RFC 1918 address space includes a subnet of 172.16.0.0 that uses a mask of 255.255.0.0?

  A. class A
  B. class B
  C. class C
  D. class D
  B. class B

  ---

  RFC 1918 defines private IP address ranges for use within private networks. The address space 172.16.0.0 to 172.31.255.255 is designated as private and falls under class B. Class B Address Space: The range 172.16.0.0 to 172.31.255.255 is a private IP address range designated for class B networks. Subnet Mask: A subnet mask of 255.255.0.0 (/16) is commonly used within this range to create subnets. References: RFC 1918 Address Allocation: RFC 1918

• Question 20:

  DRAG DROP

  Drag and drop the network automation interfaces from the left onto the transport protocols that they support on the right.
