Correct Answer:

NAS is correct.

Network attached storage (NAS) is accessible using file sharing protocols such as Common Internet File System (CIFS) and Network File System (NFS).

Incorrect Answers:

iSCSI is incorrect. Internet Small Computer Systems Interface (iSCSI) places SCSI disk I/O commands within IP packets for traversal over a standard IP network.

SAN is incorrect. Storage area networks (SANs) use specialized equipment to provide a high-speed dedicated network for storage traffic only.

LUN is incorrect. Logical unit numbers (LUNs) are allocated disk space made available to storage consumers over the network.

Correct Answer:

Synchronous is correct.

Only after all replicas report a successful data write will synchronous replication notify the app that data has been written.

Incorrect Answers:

Cloning is incorrect. Cloning is a complete copy of data.

Failover zone is incorrect. Failover zones are used for highly available application isolation.

Asynchronous is incorrect. Asynchronous replication does not wait for all replicas to confirm that data is written before notifying an app that data has been saved.

Correct Answer:

MTU is correct.

The maximum transmission unit (MTU) and maximum segment size (MSS) settings can prevent large transmissions that exceed the MTU from passing through routers.

Incorrect Answers:

SSH is incorrect. SSH is not related to larger-than-normal packet sizes.

Default gateway is incorrect. The default gateway is not related to larger-than-normal packet sizes.

ARP is incorrect. ARP is not related to larger-than-normal packet sizes.

Correct Answer:

Assign technician accounts to cloud admin roles is correct.

Built-in or custom admin roles and groups should be used to delegate specific admin tasks to technicians.

Incorrect Answers:

Modify cloud resource ACLs is incorrect. Modifying ACLs is not as efficient as using admin roles.

Create a single administrative account and provide its details to technicians is incorrect. A single admin account is never a good idea for accountability and auditing reasons.

Distribute the cloud private key to technicians is incorrect. Private key distribution to admins should be performed only rarely.

Correct Answer:

Alert notifications is correct.

Intrusion detection systems (IDSs) detect and report unusual activity events, but must be configured with details such as what is considered abnormal activity, as well as whether to send related notifications or write related entries to logs.

Incorrect Answers:

IP address blocking is incorrect. Intrusion prevention systems (IPSs), not IDSs, can block suspicious activity.

RAID 0 is incorrect. RAID 0 stripes data across multiple disks to improve storage performance.

Dual Internet connections is incorrect. Dual Internet connections will not speed up notifications if notifications have not been enabled.

Correct Answer:

P2V is correct.

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.

Incorrect Answers:

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

V2V is incorrect. Virtual to virtual (V2V) starts with a virtual machine and ends with a different virtual machine, often used when switching between hypervisors.

V2P is incorrect. Virtual to physical (V2P) starts with a virtual machine and results in a new physical server configuration.

Correct Answer:

Increase IOPS is correct.

Increasing the input/output operations per second (IOPS) value will result in better performance, but at an increased cost.

Incorrect Answers:

Replication is incorrect. Replication keeps another copy of data synchronized with the primary copy, either within the same region or further away in another region.

Storage mirroring is incorrect. Storage mirroring is a specific type of replication normally used for storage area network (SAN) disk array high availability.

Decrease IOPS is incorrect. Decreasing IOPS would decrease disk I/O performance.

Correct Answer:

Use multiple runbook servers is correct.

Runbooks can be configured to run on any available runbook server.

Incorrect Answers:

Enable runbook load balancing is incorrect. Load balancing does not normally apply to runbooks.

Configure maintenance mode is incorrect. Maintenance mode allows a system to be updated, hardware to be changed, and so on while blocking new connections.

Configure runbook replicas is incorrect. Runbooks themselves do not replicate.

Correct Answer:

DNS is correct.

Domain Name Service (DNS) is normally used to resolve fully qualified domain names (FQDNs) to IP addresses.

Incorrect Answers:

DHCP is incorrect. Dynamic Host Configuration Protocol (DHCP) is a central IP configuration that is applied to clients over the network.

NTP is incorrect. Network Time Protocol (NTP) synchronizes computer clocks over a network using UDP port 123.

NIDS is incorrect. Network-based intrusion detection systems (NIDSs) are configured to detect suspicious network activity and report and block it.

Correct Answer:

Multiple hypervisors is correct.

Multiple hypervisors are required so that the virtual machines have something to fail over to.

Incorrect Answers:

Shared storage is incorrect. Shared storage is not required for high availability, but is often used in a cluster.

Snapshot is incorrect. Snapshots are used to save the state of a virtual machine at a specific time.

V2V is incorrect. V2V (virtual to virtual) is the process of migrating one virtual machine to another.
