Zorluk: Çok zorRemote Access Technologies and Tools

A senior systems administrator is establishing a secure remote administration architecture across a corporate site-to-site VPN tunnel. Technicians require encrypted command-line shell access to manage remote Linux application servers, as well as unattended graphical remote access to manage Windows 11 Pro client workstations. Network firewalls must strictly permit only standard encrypted management traffic, while legacy unencrypted management tools must remain blocked.

Which TWO of the following host and firewall configurations must be implemented to fulfill these remote administration requirements? (Select TWO.)

  1. Permit inbound traffic on TCP port 22 on network firewalls and enable the SSH service on the target Linux servers.Cevap
  2. Enable the 'Allow Remote connections to this computer' setting on the Windows 11 Pro workstations and allow inbound traffic on TCP port 3389 on local firewalls.Cevap
  3. C
    Permit inbound traffic on TCP port 23 on network firewalls to allow command-line administrative access for the Linux application servers.
  4. D
    Configure Microsoft Remote Assistance (MSRA) for unattended background connections on workstations running Windows 11 Home edition.

Cevap

The correct configurations are allowing inbound TCP port 22 for SSH services on the Linux servers and enabling Remote Desktop with inbound TCP port 3389 access on the Windows 11 Pro workstations.
Secure command-line management of Linux systems requires SSH, which uses TCP port 22 and encrypts all session traffic. For unattended Windows graphical administration, Remote Desktop Protocol (RDP) on TCP port 3389 must be enabled on supported Windows editions such as Windows 11 Pro or Enterprise.

Adım Adım Çözüm

1
Identify the protocol and port requirements for encrypted command-line Linux management.
SSH provides secure, encrypted shell sessions and uses standard default port TCP 22.
SSH protects administrative authentication and shell commands from sniffing across the network.
2
Identify the protocol and port requirements for unattended graphical Windows management.
Remote Desktop Protocol (RDP) provides graphical unattended access on TCP port 3389 and is supported for hosting on Windows 11 Pro/Enterprise editions.
RDP allows administrators to control remote Windows desktops completely without requiring a local user to initiate or approve the session.
3
Evaluate distractors based on security standards and Windows OS edition constraints.
Reject Telnet (TCP 23) due to lack of encryption, and reject MSRA for unattended access due to mandatory interactive session acceptance.
Security baselines prohibit unencrypted protocols like Telnet, and unattended access requires RDP rather than MSRA.
