Correct Answer:

Missing dependencies is correct.

In some cases, missing software dependencies that have not yet been updated can cause higher-level updates from applying correctly. This can sometimes result in the rolling back of failed updates.

Incorrect Answers:

Insufficient permissions is incorrect. Since the Linux machines are configured similarly, insufficient permissions are not a likely cause of the problem.

Insufficient network bandwidth is incorrect. Since the Linux machines are configured similarly, bandwidth is not a likely cause of the problem.

Missing baselines is incorrect. Since the Linux machines are configured similarly, baselines are not a likely cause of the problem.

Correct Answer:

DMZ is correct.

A demilitarized zone (DMZ) is a network where public-facing resources should be placed. Traffic into the DMZ from the Internet is controlled, and traffic from the DMZ to private networks is also controlled.

Incorrect Answers:

On-premises is incorrect. The scenario states the website will be deployed in the cloud.

Isolated cloud network is incorrect. An isolated network does not allow Internet access; this is a public website.

Internet is incorrect. Public websites should be placed on a DMZ and should be directly connected to the Internet.

Correct Answer:

Load balancer is correct.

Adding the appropriate entry to a network route table controls traffic flow.

Incorrect Answers:

Load balancer is incorrect. A load balancer improves application performance by using multiple back-end servers.

Firewall rule is incorrect. Firewalls control network traffic and host inbound and outbound traffic.

NAT gateway is incorrect. Network address translation (NAT) gateways allow multiple private hosts to use a single public IP address for Internet connectivity.

Correct Answer:

Virtual machine snapshot is correct.

A virtual machine snapshot can be taken quickly and provides the fastest method of rolling back to a previous configuration.

Incorrect Answers:

Virtual machine clone is incorrect. Virtual machine clones are complete copies and thus take more time to create than a snapshot.

Virtual machine replica is incorrect. Virtual machine replicas are complete copies and thus take more time to create than a snapshot. Replicas differ from clones in that they are kept in sync with each other.

Virtual machine template is incorrect. Virtual machine templates are used to deploy virtual machines, not roll them back to a previous configuration.

Correct Answer:

VPN is correct. Virtual private networks (VPNs) create encrypted tunnels between two endpoints.

Incorrect Answers:

Load balancer is incorrect. A load balancer does not provide a secured network connection between two networks.

NAT gateway is incorrect. A NAT gateway does not provide a secured network connection between two networks.

Route table is incorrect. A route table does not provide a secured network connection between two networks.

Correct Answer:

Load balancing is correct.

Hot sites require not only equipment but also up-to-date data, which is achieved through constant replication from the primary site.

Incorrect Answers:

Load balancing is incorrect. Load balancing increases app performance by distributing incoming client requests to multiple back-end servers.

Disk encryption is incorrect. Disk encryption is not required for hot sites.

File hashing is incorrect. File hashing is not required for hot sites.

Correct Answer:

Follow the sun is correct.

Follow the sun (FTS) means that as the workday ends in one time zone, a new shift begins in the next time zone. For large international organizations, this means 24/7 productivity.

Incorrect Answers:

Maintenance windows is incorrect. Maintenance windows are time frames during which tasks such as updates can be applied.

Peak hours is incorrect. Peak hours are busy times.

Downtime is incorrect. Downtime refers to service unavailability.

Correct Answer:

Authentication is correct. Authentication is proof of identity, such as a user logging in with a name and password.

Incorrect Answers:

Authorization is incorrect.

Authorization to use resources occurs after successful authentication.

PKI is incorrect. Public key infrastructure (PKI) uses a hierarchy of security certificates.

MFA is incorrect. Multifactor authentication (MFA) uses two or more categories of authentication, such as the possession of a smartcard and knowledge of the PIN.

Correct Answer:

Deduplication is correct. Deduplication removes duplicate data blocks from disk and keeps only a single copy and uses pointers from file references.

Incorrect Answers:

Compression is incorrect. Compression removes duplicate file contents, but not at the data block level.

Thin provisioning is incorrect. Using thin provisioning means the sum of disk volume configured space can exceed physically available storage space; the space is not allocated immediately. Instead, disk volumes consume space as they need it dynamically.

Thick provisioning is incorrect. Thick provisioning allocates the physical space to a volume at creation time.

Correct Answer:

The file server is running SMB 1, which is not enabled by default on Server 2019 is correct.

SMB 1 is an older, insecure network protocol and is disabled by default on Windows Server 2019.

Incorrect Answers:

You need to set different firewall rules for SMB access from Windows Server 2019 is incorrect. Standard firewall rules for SMB apply to Windows Server 2019.

All network traffic is blocked between the virtual machine and the file server is incorrect. All traffic cannot be blocked, as you are able to ping the file server from the virtual machine.

The virtual machine does not have the proper credentials to log into the file server is incorrect. The developer reports never being asked for credentials, only being presented with an error.
