Cisco CCNA 200-301 Practice Question

Configuring dynamic inside source translation using an address pool allows internal hosts to access external networks by dynamically mapping their private addresses to a pool of public addresses. This way, when an internal host initiates a connection, the router assigns an available public address from the pool without manual configuration for each host. Static inside source translation requires manual one-to-one mapping between private and public addresses, which the administrator wants to avoid. Port Address Translation (PAT) allows multiple internal hosts to share a single public address, which is unnecessary when multiple public addresses are available. Outside source translation is used for translating external addresses to internal addresses, which does not meet the requirement.
