Zorluk: ZorNetwork Host Services and Server Roles

A network technician is deploying core host infrastructure for a new branch office location. The branch needs local automated IP address configuration and internal name resolution capabilities that remain operational even if the WAN link to headquarters drops. Company policy strictly prohibits endpoint devices from resorting to APIPA link-local addressing or using external public resolvers. Which TWO of the following host server roles should the technician install and configure on the local branch server to satisfy these requirements? (Select TWO.)

  1. DHCP server role to automatically lease IP addresses, subnet masks, and default gateway settings to client endpointsCevap
  2. DNS server role to host local lookup zones and resolve internal hostnames to IP addresses for branch resourcesCevap
  3. C
    Syslog server role operating on UDP port 67 to process dynamic client address assignments and gateway options
  4. D
    APIPA host service role configured to dynamically assign public routable IP addresses across subnets

Cevap

The technician must deploy a local DHCP server role to handle IP address leases and a local DNS server role to manage internal hostname-to-IP resolution.
To satisfy local independence and prevent client fallback behavior, the server requires a DHCP role (to supply IP addresses, masks, and gateway information dynamically) and a DNS role (to resolve hostnames locally without WAN access).

Adım Adım Çözüm

1
Analyze the requirement for local, automated IP address distribution.
Dynamic Host Configuration Protocol (DHCP) is the host service responsible for leasing IP addresses, subnet masks, default gateways, and DNS server pointers to endpoints.
Deploying DHCP locally ensures clients receive proper network configurations without relying on remote servers across a potentially disconnected WAN.
2
Analyze the requirement for internal name resolution.
Domain Name System (DNS) is the server role that resolves human-readable hostnames to network IP addresses.
Hosting a DNS server at the branch location allows local name queries to resolve independently of external internet or corporate WAN connectivity.
3
Evaluate and eliminate incorrect host roles.
Syslog aggregates event logs rather than managing network settings, and APIPA is an unmanaged client fallback mechanism rather than an infrastructure server role.
Distinguishing between log management, client fallback mechanisms, and active configuration services ensures accurate role selection.
