Question 1

In manual allocation,IP addresses are assigned by DHCP _____.&#10;A)automatically and forever,based on a first-come-first-serve basis,from a pool of addresses&#10;B)manually and forever on a per-host basis&#10;C)automatically and for a short period,based on a first-come-first-serve basis,from a pool of addresses&#10;D)None of the above

Accepted Answer

In manual allocation, a DHCP server assigns IP addresses manually to specific hosts based on pre-configured mappings. This allocation is typically permanent for each host, unlike dynamic allocation which assigns addresses automatically for a limited duration.

Question 2

In most networks,hosts are assigned IP addresses _____.&#10;A)manually&#10;B)using DNS&#10;C)using DHCP&#10;D)using NAT

Accepted Answer

In most networks, hosts are assigned IP addresses using DHCP (Dynamic Host Configuration Protocol). DHCP is a protocol that automatically assigns IP addresses to network hosts. It is the most common way of assigning IP addresses because it is efficient, easy to manage, and minimizes the chances of address conflicts. Manually assigning IP addresses can be time-consuming and error-prone, while DNS (Domain Name System) is a service that translates domain names into IP addresses but does not necessarily assign them to hosts. NAT (Network Address Translation) is a technique used to map a public IP address to a private IP address and is not used for assigning IP addresses to hosts.

Question 3

Clients locate the DNS server on their network because _____.&#10;A)the IP address of the DNS server is typically programmed into the computer&#10;B)all computers on the network act as DNS servers&#10;C)the client can typically act as its own DNS server&#10;D)they obtain it using DHCP at boot time

Accepted Answer

DHCP (Dynamic Host Configuration Protocol) automatically assigns network settings, including the IP address of the DNS server, to clients at boot time. Therefore, clients obtain the DNS server address from the DHCP server, which is typically located on the network. Choices A and C are not entirely accurate, as clients may not be programmed or configured to act as their own DNS servers. Choice B is not accurate, as having multiple DNS servers on a network can cause conflicts and issues.

Question 4

A limitation of network address translation is that _____.&#10;A)it wastes IP addresses&#10;B)it adds complexity to DNS&#10;C)it cannot be used with RFC 1918 addresses&#10;D)it cannot be used to assign IP addresses to servers

Accepted Answer

The answer of A limitation of network address translation is...

Question 5

Network address translation is the method of _____.&#10;A)allocating IP addresses automatically&#10;B)mapping IP addresses from one address block to another address block&#10;C)translating host names to IP addresses&#10;D)allocating IP address blocks to ISPs

Accepted Answer

Network address translation involves mapping IP addresses from one address block to another, typically to allow multiple devices on a private network to share a single public IP address. It does not involve automatic allocation of IP addresses, translating host names, or allocating IP address blocks to ISPs.

Question 6

Manual allocation by DHCP is useful for _____.&#10;A)client PCs&#10;B)servers such as workstations&#10;C)non-server networked devices such as printers&#10;D)None of the above

Accepted Answer

Manual allocation by DHCP is useful for non-server networked devices such as printers because these devices may have static IP addresses that need to be reserved and managed by the DHCP server. Client PCs and servers such as workstations are typically assigned dynamic IP addresses by the DHCP server.

Question 7

Non-routable addresses are useful because _____.&#10;A)they enable IP address reuse&#10;B)they enable automatic assignment of IP addresses&#10;C)they enable translation of host names to IP addresses&#10;D)they are reserved for academic use

Accepted Answer

Non-routable addresses (such as those allocated for private networks like 192.168.x.x and 10.x.x.x) are useful because they enable IP address reuse, since they can be used by multiple devices on different private networks without conflict with public IP addresses. This helps to conserve the limited number of available public IP addresses.

Question 8

In dynamic allocation,IP addresses are assigned by DHCP _____.&#10;A)automatically and forever,based on a first-come-first-serve basis,from a pool of addresses&#10;B)manually and forever on a per-host basis&#10;C)automatically and for a short period,based on a first-come-first-serve basis,from a pool of addresses&#10;D)None of the above

Accepted Answer

In dynamic allocation, IP addresses are assigned by DHCP automatically and for a short period of time, based on a first-come-first-serve basis, from a pool of addresses. This means that the DHCP server assigns IP addresses to devices on the network as they request them, and the lease on the address is temporary and typically expires after a set time. This allows for efficient use of the available IP addresses and can also help in managing network traffic and security.

Question 9

When a client wishes to translate the hostname www.example.com,it sends a translation request to _____.&#10;A)the DNS server identified by DHCP&#10;B)the DNS server responsible for the example.com domain&#10;C)the DNS server responsible for all &#34;.com&#34; domains&#10;D)any DNS server

Accepted Answer

The client typically sends a translation request to the DNS server identified by DHCP, which is usually the local DNS server configured by the network settings. This server will then handle the query, potentially forwarding it to other DNS servers if necessary.

Question 10

Network address translation is useful because it enables _____.&#10;A)the automatic allocation of IP addresses&#10;B)the translation of host names to IP addresses&#10;C)IP address reuse&#10;D)the allocation of IP address blocks to ISPs

Accepted Answer

Network address translation (NAT) allows for the reuse of IP addresses by translating private IP addresses used within a local network into a single public IP address that can be used to communicate with other networks on the internet. This conserves public IP addresses and allows for more efficient use of the limited address space.
