To confirm the issue of slow network performance when accessing on-premises email, a network technician shouldcompare the network baselines to the current network status. Here's why:

Reviewing logging levels of network devices(Option A) may provide information about device behavior but won't directly confirm the email performance issue.

Checking audit logs(Option B) is useful for security purposes but doesn't specifically address network performance.

Verifying LDAP accounts(Option D) is relevant for authentication but doesn't directly relate to network performance.

Therefore, the correct answer isC. Compare the network baselines to the current network status

The situation in which an employee knowingly allows someone access to a restricted area without verifying authentication is calledTailgating. Here's why:

Piggybacking(Option A) refers to an unauthorized person following an authorized person into a secure area without their knowledge.

Shoulder surfing(Option C) involves someone observing sensitive information (such as passwords) by looking over another person's shoulder.

Phishing(Option D) is a form of social engineering where attackers deceive individuals into revealing confidential information.

Therefore, the correct answer isB. Tailgating

Since neither of the switches supports MDIX, the systems administrator should use aCrossover cableto connect the two network switches via copper cabling. Here's why:

Straight cable(Option A) is used to connect different types of devices (e.g., switch to computer) and not switches to switches.

Crossover cable(Option B) is specifically designed for connecting similar devices (e.g., switch to switch, switch to hub) without MDIX support.

Patch cable(Option C) is a general term for Ethernet cables and doesn't specify whether it's straight or crossover.

Rollover cable(Option D) is used for console connections to network devices (e.g., connecting to a router or switch console port).

Therefore, the correct answer isB. Crossover

The correct option for this scenario isE. Reservation. DHCP reservations allow the administrator to assign a specific IP address to a device based on its MAC address. This ensures that the device always receives the same IP address from the DHCP server.

Dynamic assignment: This is the default behavior of DHCP, where IP addresses are assigned dynamically from a pool of available addresses.

Static IP on the server: This is not related to DHCP reservations. A static IP address is manually configured on the device itself, not assigned by the DHCP server.

IP helper: IP helper is used to forward DHCP requests across different subnets, but it doesn't specifically address MAC-based IP assignment.

Exclusion range: Exclusion ranges are used to prevent certain IP addresses from being assigned dynamically by DHCP. They do not assign specific IP addresses based on MAC addresses.

Reservation: DHCP reservations allow the administrator to assign specific IP addresses to devices based on their MAC addresses. This ensures consistent IP assignments for specific devices.

The correct port to open for mapping a network file share (such as SMB/CIFS) to a local drive isB. 445. Port 445 is used for Microsoft's SMB (Server Message Block) protocol, which facilitates file and printer sharing over a network.

Port 389: This is used for LDAP (Lightweight Directory Access Protocol) communication.

Port 514: This is used for syslog traffic.

Port 636: This is used for secure LDAP (LDAPS) communication.

Port 445: This is the standard port for SMB/CIFS (Common Internet File System) traffic. It allows for file and printer sharing between Windows devices.

The printer should be on the same subnet as the workstation to communicate.

If the printer's IP address and subnet mask do not align with the workstation's network, it won't connect.

Adjusting the printer's IP address and subnet mask to match the network configuration will likely resolve the issue.

High availability refers to systems that are durable and likely to operate continuously without failure for a long time.

Using a load balancer to distribute requests between production and cloud environments ensures that if one environment fails, the other can take over, thus providing high availability.

The correct tool for verifying existing network connections on a server isC. Netstat. Netstat (network statistics) displays active network connections, routing tables, interface statistics, masquerade connections, and multicast memberships.

Tracert: Tracert (traceroute) is used to trace the route taken by packets from the source to the destination. It helps identify the path and latency between routers.

Ipconfig: Ipconfig is used to view and manage IP configuration settings on a local machine (such as IP address, subnet mask, default gateway, etc.). It does not provide information about existing connections.

Netstat: Netstat displays active network connections, including listening ports, established connections, and associated processes. It's useful for troubleshooting and monitoring network activity.

Nslookup: Nslookup is used for DNS (Domain Name System) queries to resolve domain names to IP addresses. It does not provide information about existing connections.

The correct port available for connecting to a SQL database via command-line interface isD. 1521. Port 1521 is the default port for Oracle Database connections using the Oracle Net Services (SQL*Net) protocol.

Port 143: This is used for IMAP (Internet Message Access Protocol) communication.

Port 445: This is used for Microsoft's SMB (Server Message Block) protocol (file and printer sharing).

Port 993: This is used for secure IMAP (IMAPS) communication.

Port 1521: This is the default port for Oracle Database connections using the Oracle Net Services (SQL*Net) protocol.
