                        Premises: A way of segmenting a network logically such that ports on a switch can be divided into logical groupings and act as a separate logical network.
A way of managing the flow of data across complex switched network environments that can include both physical and virtual switches.
A method of gaining access to the underlying host through flaws in the hypervisor.
A virtual switch similar to a Private Virtual Network in that it isn't bound to any physical NIC.
Used to determine the MAC address associated with an IP address within the sender's network.
A memory management protocol used in multiprocessing environments, allowing for a CPU to access local memory faster than memory that is shared with other processors.
Occurs when an attacker searches for information about the target using publicly available sources such as Web sites or Facebook pages.
A virtual switch that can be accessed from VMs running on any host managed by vCenter Server.
A common open source protocol used to communicate between switches and a management server.
Occurs when a hacker uses tools such as Network Mapper (NMAP) to look for open network ports and other vulnerable aspects of a system or applications.

Question 2

What phase of an attack implies a hacker is actively attacking a system and applications using vulnerabilities discovered in the other phases?

Accepted Answer

The exploitation phase of an attack involves actively attacking a system and applications using the vulnerabilities discovered in the earlier phases, such as the reconnaissance and scanning phases. This is when the attacker leverages the identified vulnerabilities to gain unauthorized access or perform unauthorized actions on the target system.

Question 3

The process of storing a single copy of a data sector and then using reference pointers to access this data from other locations is known by what term?

Accepted Answer

Data deduplication is the process of eliminating duplicate copies of repeating data to improve storage utilization. In this context, storing a single copy of a data sector and using reference pointers for access aligns with the concept of data deduplication.

Question 6

What VMware vSphere technology allows you to move not only a running virtual machine to a different vSphere host, but also the files associated with the virtual machines to a different data store?

Accepted Answer

Storage vMotion allows for the migration of a virtual machine's storage to a different datastore while the VM is running, which includes moving the files associated with the virtual machines.

Question 7

What type of malware is a virus that operates at the same privilege as the hypervisor and utilizes various methods to hide from detection?

Accepted Answer

A rootkit is designed to hide the existence of certain processes or programs from normal methods of detection and can operate at the same privilege level as the hypervisor, making it particularly stealthy and dangerous.

Question 8

What VMware technology is used by VMware FT to keep the secondary virtual machine up to date with the active primary virtual machine?

Accepted Answer

VMware FT (Fault Tolerance) uses VMware vLockstep technology to keep the secondary virtual machine in sync with the primary virtual machine, ensuring that all operations are replicated in real-time for instant failover in case of a failure.

Question 9

Under what conditions can you dynamically change the number of vCPUs or memory available to a guest OS?

Accepted Answer

The guest OS must support the dynamic addition of CPUs and memory for changes to be made while the system is running.

Question 13

What are the two different types of Storage Area Network system?

Accepted Answer

Fibre Channel and iSCSI are two different types of Storage Area Network (SAN) systems. Fibre Channel is a high-speed network technology primarily used for storage networking, while iSCSI (Internet Small Computer System Interface) allows the use of the TCP/IP network to carry SCSI commands, allowing for the use of existing network infrastructure for storage.

Question 14

What statement regarding the use of an IDS is not accurate?

Accepted Answer

An IDS (Intrusion Detection System) is designed to monitor and analyze network traffic to detect suspicious activities and security breaches, such as denial of service attacks or infected machines. However, it does not improve the performance of a virtual network; in fact, it may introduce a slight overhead due to its monitoring activities.
