3. Question 153 · 264 in bank

   Your on-premises network has an IP address range of 10.0.0.0/23. You have an Azure virtual network named VNet1 that contains a virtual machine named VM1. VNet1 has an IP address range of 10.0.1.0/24. You need to deploy a Site-to-Site (S2S) VPN to connect the on-premises network to VNet1. What should you do first?

   • ADeploy Azure Bastion to VNet1.
   • BDeploy Azure Extended Network.
   • CConfigure VNet1 to use the IP address range of 10.0.2.0/24.
   • DConfigure VNet1 to use an IP address range of 10.0.1.128/25.

   Show answer

   Answer: C

   Explanation

   Since your on-premises network has an IP address range of 10.0.0.0/23 and VNet1 currently has an IP address range of 10.0.1.0/24, which overlaps with the on-premises network, you need to change the IP address range of VNet1 to ensure that it does not overlap with the on-premises network. Therefore, the correct option is: C. Configure VNet1 to use the IP address range of 10.0.2.0/24.

   You have a server that runs Windows Server 2022 and has the network adapters shown in the following table.

   

   You need to configure NIC teaming for LAN2 and LAN3. The solution must support Dynamic Virtual Machine Multi-Queue (d.VMMQ). What should you use?

   • ALACP teaming mode
   • BSwitch Embedded Teaming (SET)
   • Cload balancing and failover (LBFO)
   • DStatic teaming mode

   Show answer

   Answer: B

   Explanation

   Based on the information provided, you should use B. Switch Embedded Teaming (SET). SET is a feature available in Windows Server 2016 and later versions, including Windows Server 2022. It allows you to group between one and eight physical Ethernet network adapters into one or more software-based virtual network adapters. These virtual network adapters provide the same level of functionality as any other physical network adapter in a system. Moreover, SET supports various features such as RDMA (Remote Direct Memory Access), which is supported by LAN2 and LAN3 according to the table, and Dynamic Virtual Machine Multi-Queue (d.VMMQ). Therefore, SET is the correct choice for configuring NIC teaming for LAN2 and LAN3. Please note that while configuring SET, ensure that all the network adapters that you want to add to a SET team are of the same speed. In this case, both LAN2 and LAN3 have a link speed of 25 Gbps, so they can be added to a SET team.

   You have a Windows Server container host named Server1. You create a Dockerfile named df1. You need to generate a container image by using df1. Which command should you run?

   • Adocker build
   • Bdocker exec
   • Cdocker create
   • Ddocker images

   Show answer

   Answer: A

   Explanation

   Docker Build: This command is specifically designed to create a container image from a Dockerfile. It reads the instructions in the Dockerfile and builds the image layer by layer. docker build -t -f df1

7. Question 157 · 264 in bank

   You have an Azure virtual machine named VM1 that runs Windows Server. You perform the following actions on VM1: ✑ Create a folder named Folder1 on volume C. ✑ Create a folder named Folder2 on volume D. ✑ Add a new data disk to VM1 and create a new volume that is assigned drive letter E. ✑ Install an app named App1 on volume E. You plan to resize VM1. Which objects will present after you resize VM1?

   • AFolder1, volume E, and App1 only
   • BFolder1 only
   • CFolder1 and Folder2 only
   • DFolder1, Folder2, App1, and volume E

   Show answer

   Answer: A

   Explanation

   the answer is A, folder 2 is on D: which by default is the scratch disk that is wiped on a re-boot, a re-size of the VM requires a reboot of the VM, therefore the contents of D will be wiped

8. Question 158 · 264 in bank

   HOTSPOT - You have a Windows Server 2022 container host named Host1 that has the Subsystem for Linux installed and the container images shown in the following table.

   

   You need to deploy the images to Host1. The solution must maximize the isolation of the containers. Which images can you run by using process isolation, and which images can you run by using Hyper-V isolation? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

   

   This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.

   Show the answer figure

   Answer: See figure below

   Explanation

   Process Isolation: Image1 (Windows Server 2022): Can be run using process isolation because the container image matches the host OS version. Hyper-V Isolation: Image2 (Windows Server 2019): Requires Hyper-V isolation because it is an older version than the host OS. Image3 (Windows Server 2016): Requires Hyper-V isolation for the same reason as Image2. Image4 (Linux): Requires Hyper-V isolation because Linux containers need to run inside a virtual machine on a Windows host.
