Question #22
You have an SAP environment on Azure that uses multiple subscriptions.
To meet GDPR requirements, you need to ensure that virtual machines are deployed only to the West Europe and North Europe Azure regions.
Which Azure components should you use?
  1. A
    Azure resource locks and the Compliance admin center
  2. B
    Azure resource groups and role-based access control (RBAC)
  3. C
    Azure management groups and Azure Policy
  4. D
    Azure Security Center and Azure Active Directory (Azure AD) groups

Correct Answer:
C
Azure Policy enables you to set policies to conform to the GDPR. Azure Policy is generally available today at no additional cost to Azure customers. You can use
Azure Policy to define and enforce policies that help your cloud environment become compliant with internal policies as well as external regulations.
Azure Policy is deeply integrated into Azure Resource Manager and applies across all resources in Azure. Individual policies can be grouped into initiatives to quickly implement multiple rules. You can also use Azure Policy in a wide range of compliance scenarios, such as ensuring that your data is encrypted or remains in a specific region as part of GDPR compliance. Microsoft is the only hyperscale cloud provider to offer this level of policy integration built in to the platform for no additional charge.

Question #23
HOTSPOT -
You have an Azure Availability Set that is configured as shown in the following exhibit.

Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.
NOTE: Each correct selection is worth one point.
Hot Area:


Correct Answer:

 Box 1: the same fault domain -
Fault domains define the group of virtual machines that share a common power source and network switch. If a storage fault domain fails due to hardware or software failure, only the VM instance with disks on the storage fault domain fails.

Box 2: managed disks -
Managed disks provide better reliability for Availability Sets by ensuring that the disks of VMs in an Availability Set are sufficiently isolated from each other to avoid single points of failure. It does this by automatically placing the disks in different storage fault domains (storage clusters) and aligning them with the VM fault domain.

Question #24
A customer that has a large enterprise SAP environment plans to migrate to Azure. The environment uses servers that run Windows Server 2016 and Microsoft
SQL Server.
The environment is critical and requires a comprehensive business continuity and disaster recovery (BCDR) strategy that minimizes the recovery point objective
(RPO) and the recovery time objective (RTO).
The customer wants a resilient environment that has a secondary site that is at least 250 kilometers away.
You need to recommend a solution for the customer.
Which two solutions should you recommend? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
  1. A
    warm standby virtual machines in paired regions
  2. B
    Azure Traffic Manager to route incoming traffic
  3. C
    warm standby virtual machines in an Azure Availability Set that uses geo-redundant storage (GRS)
  4. D
    an internal load balancer to route Internet traffic
  5. E
    warm standby virtual machines in Azure Availability Zones

Correct Answer:
AC
A: An Azure Region Pair is a relationship between two Azure Regions within the same geographic region for disaster recovery purposes. If one of the regions were to experience a disaster or failure, then the services in that region will automatically failover to that regions secondary region in the pair.
C: For increased availability, you can deploy two VMs with two HANA instances within an Azure availability set that uses HANA system replication for availability.

Question #25
You plan to deploy an SAP environment on Azure that will use Azure Availability Zones.
Which load balancing solution supports the deployment?
  1. A
    Azure Basic Load Balancer
  2. B
    Azure Standard Load Balancer
  3. C
    Azure Application Gateway v1 SKU

Correct Answer:
B
When you deploy Azure VMs across Availability Zones and establish failover solutions within the same Azure region, some restrictions apply:
✑ You can't use an Azure Basic Load Balancer to create failover cluster solutions based on Windows Server Failover Clustering or Linux Pacemaker. Instead, you need to use the Azure Standard Load Balancer SKU.
References:
https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/sap-ha-availability-zones

Question #26
You have an Azure subscription.
Your company has an SAP environment that runs on SUSE Linux Enterprise Server (SLES) servers and SAP HANA. The environment has a primary site and a disaster recovery site. Disaster recovery is based on SAP HANA system replication. The SAP ERP environment is 4 TB and has a projected growth of 5% per month.
The company has an uptime Service Level Agreement (SLA) of 99.99%, a maximum recovery time objective (RTO) of four hours, and a recovery point objective
(RPO) of 10 minutes.
You plan to migrate to Azure.
You need to design an SAP landscape for the company.
Which options meet the company's requirements?
A.
✑ Azure virtual machines and SLES for SAP application servers
✑ SAP HANA on Azure (Large Instances) that uses SAP HANA system replication for high availability and disaster recovery
B.
✑ ASCS/ERS and SLES clustering that uses the Pacemaker fence agent
✑ SAP application servers deployed to an Azure Availability Zone
✑ SAP HANA on Azure (Large Instances) that uses SAP HANA system replication for database high availability and disaster recovery
C.
✑ SAP application instances deployed to an Azure Availability Set
✑ SAP HANA on Azure (Large Instances) that uses SAP HANA system replication for database high availability and disaster recovery
D.
✑ ASCS/ERS and SLES clustering that uses the Azure fence agent
SAP application servers deployed to an Azure Availability Set

✑ SAP HANA on Azure (Large Instances) that uses SAP HANA system replication for database high availability and disaster recovery

Correct Answer:
B
With Availability Zones, Azure offers industry best 99.99% VM uptime SLA.

Question #27
DRAG DROP -
Your on-premises network contains an Active Directory domain.
You have an SAP environment on Azure that runs on SUSE Linux Enterprise Server (SLES) servers.
You configure the SLES servers to use domain controllers as their NTP servers and their DNS servers.
You need to join the SLES servers to the Active Directory domain.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Select and Place:


Correct Answer:

 Step 1: Install the samba-winbind package

Install samba-winbind -
Step 2: Add realm details to /etc/krb5.conf and /etc/samba/smb.conf
Edit files - best way to do this is to use yast on test machine and copy files from it
In following examples you need to replace EXAMPLE/EXAMPLE.COM/.example.com with your values/settings
/etc/samba/smb.conf
[global]
workgroup = EXAMPLE
usershare allow guests = NO #disallow guests from sharing
idmap gid = 10000-20000
idmap uid = 10000-20000
kerberos method = secrets and keytab
realm = EXAMPLE.COM
security = ADS
template homedir = /home/%D/%U
template shell = /bin/bash
winbind offline logon = yes
winbind refresh tickets = yes

/etc/krb5.conf
[libdefaults]
default_realm = EXAMPLE.COM
clockskew = 300
[realms]
EXAMPLE.COM = {
kdc = PDC.EXAMPLE.COM
default_domain = EXAMPLE.COM
admin_server = PDC.EXAMPLE.COM
}
..
Step 3: Run net ads join -U administrator
Join the SLES 12 Server to the AD domain

Solution: You use Monitoring from the SAP HANA Cockpit.
Does this meet the goal?
  1. A
    Yes
  2. B
    No

Correct Answer:
A
The SAP HANA cockpit provides a single point of access to a range of SAP HANA administration and monitoring tasks. It is used to monitor and ensure the overall health of the system.
The HANA Monitoring dashboard also visualizes key HANA Metrics of SAP HANA system.

Question #30
HOTSPOT -
You have SAP ERP on Azure.
For SAP high availability, you plan to deploy ASCS/ERS instances across Azure Availability Zones and to use failover clusters.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:


Correct Answer:

 Box 1: No -
You can't use an Azure Basic Load Balancer to create failover cluster solutions based on Windows Server Failover Clustering or Linux Pacemaker. Instead, you need to use the Azure Standard Load Balancer SKU.

Box 2: Yes -
Azure Availability Zones is one of the high-availability features that Azure provides. Using Availability Zones improves the overall availability of SAP workloads on
