Correct Answer:

`route print` is correct. The `route print` command shows the routing table on a Windows machine.

Incorrect Answers:

`arp –a` is incorrect. `arp -a` will display all entries in the computer’s ARP table.

`netstat –p tcp` is incorrect. `netstat -p tcp` will show all active TCP connections from the computer.

`ping` is incorrect. `ping` is the command to measure the round-trip latency of an ICMP request and reply.

Correct Answer:

Simultaneous multithreading is correct.

Simultaneous multithreading (SMT) is a processor technology that allows parallel instruction execution.

Incorrect Answers:

VT-x is incorrect. VT-x is Intel’s hardware virtualization firmware.

vCPU is incorrect. A vCPU is a virtual CPU used by a virtual machine.

CPU cache is incorrect. CPU cache speeds up processing by placing recently used instructions in high-speed memory.

Correct Answer:

SSH is correct.

Secure Shell (SSH) is considered a secure utility. It is used to secure logins, file transfers, and port forwarding.

Incorrect Answers:

Telnet, FTP, and POP3 are incorrect.

None of these protocols are secure.

Correct Answer:

V2V is correct.

Virtual to virtual (V2V) starts with a virtual machine and ends with a different virtual machine, often used when switching between hypervisors or migrating on-premises virtual machines to the cloud.

Incorrect Answers:

P2V is incorrect. Physical to virtual (P2V) starts with the physical machine. Agents are installed to capture the configuration data, which is then used to create a cloud virtual machine.

P2P is incorrect. Physical to physical (P2P) results in another physical server.

V2P is incorrect. Virtual to physical (V2P) starts with a virtual machine and results in a new physical server configuration or migrating on-premises virtual machines to the cloud.

Correct Answer:

Hypervisors is correct.

Hypervisors host virtual machine guests.

Incorrect Answers:

Guests is incorrect. Guest is another term for virtual machine.

Virtual appliances is incorrect. Virtual appliances are virtual machines with specialized functionality, such as firewalling.

Clusters is incorrect. Clusters are groups of machines working together to make a service highly available.

Correct Answer:

Offline migration is correct.

Offline migrations work well with large volumes of data that would take too long to transfer over the Internet; the bandwidth is simply not there. Data is copied to physical disks at the client site and then physically sent to the cloud provider data center, where it is then copied to the provider’s storage devices.

Incorrect Answers:

Data deduplication is incorrect. While data deduplication saves space, it would not reduce the size of the data sufficiently to migrate it online.

Data and network compression is incorrect. While data and network compression save space, they would not reduce the size of the data sufficiently to migrate it online.

Storage mirroring is incorrect. Storage mirroring is used to copy storage array data locally, not to a cloud provider.

Correct Answer:

Identification is correct.

Authentication is the proving of identity. Depending on organizational policies, multifactor authentication (MFA) might be required in more secure environments.

Incorrect Answers:

Single sign-on is incorrect. Single sign-on (SSO) relieves users from having to re-enter credentials as they access resources.

ACL is incorrect. Access control lists (ACLs) determine who has permissions to resources.

Authorization is incorrect. Authorization occurs after authentication; it uses ACLs to allow or deny resource access.

Correct Answer:

Edge site is correct.

Edge sites improve performance by ensuring data processing and data are close together.

Incorrect Answers:

Hot site is incorrect. Hot sites contain equipment and data.

Warm site is incorrect. Warm sites contain equipment but not data.

Cold site is incorrect. Cold sites do not contain equipment or data.

Correct Answer:

Differential is correct. Differential backups capture changes since the last full backup.

Incorrect Answers:

Incremental is incorrect. Incremental backups capture changes from the previous incremental backup.

Full is incorrect. Full backups take a copy of all data from the configured backup source and should be scheduled such that there is enough time to complete the backup. Full backups are often stored offline to prevent malware infections.

Copy-on-write is incorrect. Snapshot copy-on-writes ensure original data is still available by copying disk blocks when write requests are made.

Correct Answer:

Rapid elasticity is correct. Rapid elasticity allows for the quick provisioning and deprovisioning of cloud resources.

Incorrect Answers:

Broad access is incorrect. Broad access allows access to cloud services over a network using a wide variety of devices.

Metered usage is incorrect. Metered usage tracks consumption; cloud customers therefore pay only for what they use.

Self-provisioning is incorrect. Self-provisioning is done via a GUI or CLI, which allows users to add or remove cloud resources as they see fit.
