Installing server equipment in a rack increases compute density by allowing multiple servers to be organized efficiently in a vertical configuration, saving space while housing more devices in a smaller footprint. This is critical for data centers and businesses with high hardware demands.

Simplified troubleshooting process (A): While racks can aid in organizing equipment, this is a secondary benefit, not the primary purpose.

Decreased power consumption (B): Rack installation does not directly reduce power usage; equipment power consumption remains the same.

Improved network performance (C): Racking servers does not inherently improve network performance; that depends on network configurations.

The correct solution is a Data Center Interconnect (DCI). DCIs extend Layer 2 networks across geographically dispersed data centers, enabling seamless replication of services such as SAN storage, backup synchronization, or VM migrations. This ensures workloads and data can move between sites while maintaining the same VLANs and addressing.

A. Security Service Edge (SSE) provides cloud-delivered security functions like secure web gateways and CASB, not Layer 2 extension.

C. Infrastructure as code (IaC) automates deployment and management of network infrastructure but is unrelated to extending Layer 2 domains.

D. Zero Trust architecture is a security framework ensuring strict access control but doesn’t address network connectivity between sites.

In scenarios where backups need replication between sites, Layer 2 extension is often required so systems can communicate as if they are in the same broadcast domain. DCI is specifically designed to provide this functionality reliably and securely.

To provide a complete solution for configuring the access layer switches, let's proceed with the following steps:

Identify the correct VLANs for each device and port.

Enable necessary ports and disable unused ports.

Configure fault-tolerant connections between the switches.

Port 1 Configuration (Uplink to Core Switch)

Status: Enabled

LACP: Enabled

Speed: 1000

Port 5 Configuration (Connection to Device)

Status: Enabled

LACP: Disabled

Speed: 1000

Duplex: Full

VLAN Configuration: Untagged for VLAN1 (Default)

Port 6 Configuration (Connection to Device)

Status: Enabled

Ports 1 and 2 on Switch 1 are configured as trunk ports with VLAN tagging enabled for all necessary VLANs.

Ports 3 and 4 on Switch 1 are configured for server connections with VLAN 90 untagged.

Ports 5, 6, 7, and 8 on Switch 1 are configured for devices needing access to multiple VLANs.

Unused ports on Switch 3 are disabled.

Ports 3, 4, 5, 6, and 7 on Switch 3 are enabled for default VLAN1.

Core Switch Ports should be configured as needed for uplinks to Switch 1.

Ensure LACP is enabled for redundancy on trunk ports between switches.

By following these configurations, each device will access only its correctly associated network, unused switch ports will be disabled, and fault-tolerant connections will be established between the switches.

LDAP over SSL (LDAPS) uses port 636 to provide secure, encrypted authentication for directory services.

Breakdown of Options:

A. SMTP (Simple Mail Transfer Protocol) – Uses port 25, not 636.

B. Syslog – Uses port 514 (UDP), not 636.

C. TFTP (Trivial File Transfer Protocol) – Uses port 69 (UDP), not 636.

D. LDAPS (Lightweight Directory Access Protocol Secure) – ✅ Correct answer. Uses port 636 for secure directory authentication.
