A network administrator is configuring a load balancer for two systems.
Which of the following must the administrator configure to ensure connectivity during a failover?
Click on the arrows to vote for the correct answer
A. B. C. D. E.A.
To ensure connectivity during a failover when configuring a load balancer for two systems, the network administrator must configure a Virtual IP (VIP).
A VIP is an IP address that is assigned to a group of servers, and it can be configured to automatically failover to another server in case of a hardware or software failure. The load balancer uses the VIP to distribute traffic between the servers in the group.
When a failover occurs, the load balancer automatically redirects traffic to the remaining active server(s) in the group. This ensures that users can continue to access the service without interruption.
NAT (Network Address Translation) is a technique used to map public IP addresses to private IP addresses, and vice versa. It is used to allow multiple devices to share a single public IP address. However, NAT is not relevant to ensuring connectivity during a failover when configuring a load balancer for two systems.
APIPA (Automatic Private IP Addressing) is a feature in Microsoft Windows operating systems that assigns an IP address automatically in case the computer cannot obtain an IP address from a DHCP server. It is used on small networks that do not have a DHCP server. However, APIPA is not relevant to ensuring connectivity during a failover when configuring a load balancer for two systems.
IPv6 tunneling is a technique used to encapsulate IPv6 packets within IPv4 packets to allow them to traverse an IPv4 network. It is used to enable communication between IPv6-enabled devices over an IPv4 network. However, IPv6 tunneling is not relevant to ensuring connectivity during a failover when configuring a load balancer for two systems.
Broadcast IP is an IP address used to send a message to all devices on a network segment. It is used for various network protocols, such as Address Resolution Protocol (ARP) and Dynamic Host Configuration Protocol (DHCP). However, Broadcast IP is not relevant to ensuring connectivity during a failover when configuring a load balancer for two systems.
Therefore, the correct answer is A. VIP.
