Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

According to the Forescout HPS Inspection Engine Configuration Guide and Microsoft SMB Protocol documentation, the SMB protocol version required to manage Windows XP or Windows Vista endpoints is SMB V1.0.​

SMB Version Timeline:

According to the Microsoft documentation and Forescout requirements:​

Windows Version

SMB Support

Windows XP

SMB 1.0 only

Windows Vista

SMB 1.0 and SMB 2.0

Windows 7

SMB 1.0, SMB 2.0, and SMB 2.1

Windows 8/Server 2012

SMB 2.0, SMB 2.1, and SMB 3.0

Windows 10

SMB 2.1 and SMB 3.x

Windows XP and Vista SMB Requirements:

According to Forescout documentation:​

The documentation explicitly states:

"When you require SMB signing, Remote Inspection can no longer be used to manage endpoints that cannot work with SMB signing, for example: Old Windows XP/Server 2003 systems"

This indicates that Windows XP requires SMB support, specifically SMB 1.0, which doesn't support modern SMB signing requirements.

SMB Version Negotiation:

According to the official documentation:​

When a Forescout CounterACT appliance connects to an endpoint:

Version Negotiation - Both client and server advertise their supported SMB versions

Highest Common Version Selected - The highest version supported by BOTH is used

Fallback Behavior - If SMB 2.0 is available on Vista but not supported by CounterACT, it falls back to SMB 1.0

For Windows XP (SMB 1.0 only) and Windows Vista (SMB 1.0/2.0):

Minimum Required: SMB 1.0

Maximum Supported: SMB 2.0 (Vista only)

Port Requirements for SMB 1.0:

According to the Forescout documentation:​

For Windows XP and Vista endpoints using SMB 1.0:

text

Port 139/TCP must be available

(Port 445/TCP is used for Windows 7 and above)

Historical Context:

According to the documentation:​

SMB 1.0 was the original protocol used by Windows 2000, NT, and earlier versions

Windows Vista SP1 and Windows Server 2008 introduced SMB 2.0

SMB 1.0 is considered legacy and insecure (no encryption, subject to security vulnerabilities)

Microsoft recommends disabling SMB 1.0 in modern networks

However, for legacy Windows XP and early Vista systems, SMB 1.0 is the only option.

Why Other Options Are Incorrect:

A. SMB V3.1.1 - This is the latest version, introduced with Windows Server 2016 and Windows 10; not supported on XP or Vista

C. SMB is not required for XP or Vista - Incorrect; SMB is essential for Windows manageability and script execution

D. SMB V2.0 - While Vista supports SMB 2.0, Windows XP does NOT; only SMB 1.0 works on both

E. SMB V3.0 - This requires Windows 8/Server 2012 or later; not supported on XP or Vista

Legacy Endpoint Management Considerations:

According to the documentation:​

For legacy endpoints requiring SMB 1.0:

Cannot require SMB signing (not supported in SMB 1.0)

Must allow unencrypted SMB communication

Should be isolated on network segments with security controls

Represents security risk due to SMB 1.0 vulnerabilities

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

According to the Forescout Switch Plugin Configuration Guide, Access Port ACL and Endpoint Address ACL cannot both be used concurrently on the same endpoint. These two actions are mutually exclusive because they both apply ACL rules to control traffic, but through different mechanisms, and attempting to apply both simultaneously creates a conflict.​

Switch Restrict Actions Overview:

The Forescout Switch Plugin provides several restrict actions that can be applied to endpoints:​

Access Port ACL - Applies an operator-defined ACL to the access port of an endpoint

Endpoint Address ACL - Applies an operator-defined ACL based on the endpoint's address (MAC or IP)

Assign to VLAN - Assigns the endpoint to a specific VLAN

Switch Block - Completely isolates endpoints by turning off their switch port

Action Compatibility Rules:

According to the Switch Plugin Configuration Guide:​

Endpoint Address ACL vs Access Port ACL - These CANNOT be used together on the same endpoint because:

Both actions modify switch filtering rules

Both actions can conflict when applied simultaneously

The Switch Plugin cannot determine priority between conflicting ACL configurations

Applying both would create ambiguous filtering logic on the switch

Actions That CAN Be Used Together:

Access Port ACL + Assign to VLAN -✓Can be used concurrently

Endpoint Address ACL + Assign to VLAN -✓Can be used concurrently

Switch Block + Assign to VLAN - This is semantically redundant (blocking takes precedence) but is allowed

Access Port ACL + Switch Block -✓Can be used concurrently (though Block takes precedence)

Why Other Options Are Incorrect:

A. Access Port ACL & Switch Block - These CAN be used concurrently; Switch Block would take precedence

B. Switch Block & Assign to VLAN - These CAN be used concurrently (though redundant)

C. Endpoint Address ACL & Assign to VLAN - These CAN be used concurrently

E. Access Port ACL & Assign to VLAN - These CAN be used concurrently; they work on different aspects of port management

ACL Action Definition:

According to the documentation:​

Access Port ACL - "Use the Access Port ACL action to define an ACL that addresses one or more than one access control scenario, which is then applied to an endpoint's switch port"

Endpoint Address ACL - "Use the Endpoint Address ACL action to apply an operator-defined ACL, addressing one or more than one access control scenario, which is applied to an endpoint's address"

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

The correct command to monitor system memory and CPU load with 5 second update intervals is vmstat 5. According to the official Linux documentation and Forescout CLI reference materials, the vmstat command uses a straightforward syntax where the first numerical parameter specifies the delay interval in seconds.​

vmstat Command Syntax:

The vmstat (Virtual Memory Statistics) command uses the following syntax:​

bash

vmstat [options] [delay] [count]

Where:

delay - The time interval (in seconds) between updates

count - The number of updates to display (optional; if omitted, displays indefinitely)

vmstat 5 Command:

When you execute vmstat 5:​

Updates are displayed every 5 seconds

Continues indefinitely until manually stopped

Shows memory and CPU statistics in each update

Example output:

text

procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu-----

r b swpd free buff cache si so bi bo in cs us sy id wa st

1 0 0 1166396 70768 2233228 0 0 0 13 10 24 0 0 100 0 0

0 0 0 1165568 70776 2233352 0 0 0 8 121 224 0 0 99 0 0

0 0 0 1166608 70784 2233352 0 0 0 53 108 209 0 0 100 0 0

Each line represents a new report generated at 5-second intervals.​

Memory and CPU Information Provided:

The vmstat output includes:​

Memory Columns:

free - Amount of idle memory

buff - Amount of memory used as buffers

cache - Amount of memory used as cache

swpd - Amount of virtual memory used

si/so - Memory swapped in/out

CPU Columns:

us - Time spent running user code

sy - Time spent running kernel code

id - Time spent idle

wa - Time spent waiting for I/O

st - Time stolen from virtual machine

Why Other Options Are Incorrect:

A. watch -t 5 vmstat - Incorrect syntax; -t removes headers, not set intervals; interval flag is -n, not -t

C. vmstat -t 5 - The -t option adds a timestamp to output, but doesn't set the interval; the 5 would be ignored

D. watch uptime - The uptime command displays system uptime and load average but not detailed memory/CPU stats; watch requires -n flag for interval specification

E. watch -n 10 vmstat - While syntactically valid, this uses a 10-second interval, not 5 seconds; also unnecessary since vmstat already supports delay parameter directly

Additional vmstat Examples:

According to documentation:​

bash

vmstat 5 5 # Display 5 updates at 5-second intervals

vmstat 1 10 # Display 10 updates at 1-second intervals

vmstat -t 5 5 # Display 5 updates every 5 seconds WITH timestamps

First Report Note:

According to the documentation:​

"When you run vmstat without any parameters, it shows system values based on the averages for each element since the server was last rebooted. These results are not a snapshot of current values."

The first report with vmstat 5 shows averages since last reboot; subsequent reports show statistics for each 5-second interval.​
