A network administrator is setting up a DHCP server. In addition to an IP address and subnet mask, which of the following is a critical piece of information the server typically provides to clients to enable communication outside their local network?
.
MAC Address
APIPA Address
Hostname
Default Gateway
During the DORA process, a client computer broadcasts a message across the network to find any available DHCP servers. What is this initial message called?
DHCPREQUEST
DHCPACK
DHCPOFFER
DHCPDISCOVER
A user reports they cannot access the internet. Upon checking their IP configuration, you find their address is `169.254.100.52`. What is the most likely cause of this?
The computer has been assigned a static IP address.
The router is incorrectly configured as a DHCP relay.
The DHCP server's address pool is full.
The computer failed to contact a DHCP server.
For which of the following devices would a network administrator most likely assign a static IP address instead of using DHCP?
A network printer
A smart television in the break room
A temporary employee's laptop
A guest's mobile phone
In a high-traffic public network like an airport Wi-Fi system, where users connect and disconnect frequently, how should the DHCP lease time be configured to optimise IP address allocation?
The lease time does not affect address allocation.
It should be set to a short duration.
It should be disabled entirely.
It should be set to a very long duration.
A company has two separate subnets managed by a single router. The DHCP server is located on one subnet. What must be configured on the router to allow clients on the other subnet to obtain IP addresses from this server?
A new DHCP pool on the router
A static route to the DHCP server
An Access Control List (ACL)
A DHCP helper-address
In the DHCP DORA process, after a client receives one or more DHCPOFFER messages, it sends a DHCPREQUEST message. How is this message typically sent?
As a multicast message to all DHCP servers.
As a unicast message to the chosen server.
It is not sent; the client directly sends an ACK.
As a broadcast message.
A network requires a first-hop redundancy solution that not only provides failover but also actively balances traffic across multiple gateway routers simultaneously. Which protocol is designed for this 'active/active' functionality?
GLBP (Gateway Load Balancing Protocol)
HSRP (Hot Standby Router Protocol)
APIPA (Automatic Private IP Addressing)
VRRP (Virtual Router Redundancy Protocol)
A DHCP server is configured with an address pool of `192.168.1.10` to `192.168.1.200`. A network printer is manually configured with the IP address `192.168.1.50`. What is the primary risk, and how should it be mitigated?
No issue will occur; DHCP automatically detects and avoids static IPs.
The printer will be unable to communicate; its IP should be outside the subnet.
An IP address conflict could occur; the printer's IP should be excluded from the DHCP pool.
The DHCP server will crash; the server's own IP must be outside the pool.
A typical home router connects to an Internet Service Provider (ISP) and provides network access to devices within the home. In this context, what are the DHCP roles of the home router?
It acts only as a DHCP client.
It acts as a DHCP server for the home network and a DHCP client for the ISP network.
It acts as a DHCP relay agent for the ISP.
It acts only as a DHCP server.
