A user policy helps in defining what users can and should do to use network and organization's computer
equipment. It also defines what limitations are put on users for maintaining the network secure such as
whether users can install programs on their workstations, types of programs users are using, and how users
can access data.
Answer option C is incorrect. IT policy includes general policies for the IT department. These policies are
intended to keep the network secure and stable. It includes the following:
Virus incident and security incident
Backup policy
Client update policies
Server configuration, patch update, and modification policies (security)
Firewall policies Dmz policy, email retention, and auto forwarded email policy
Answer option A is incorrect. It defines the high level program policy and business continuity plan.
Answer option B is incorrect. Remote access policy is a document that outlines and defines acceptable
methods of remotely connecting to the internal network.

The Distance Vector Multicast Routing Protocol (DVMRP) is used to share information between routers to
transport IP Multicast packets among networks. It uses a reverse path-flooding technique and is used as the
basis for the Internet's multicast backbone (MBONE). In particular, DVMRP is notorious for poor network
scaling, resulting from reflooding, particularly with versions that do not implement pruning. DVMRP's flat
unicast routing mechanism also affects its capability to scale.
Answer option A is incorrect. The Resource Reservation Protocol (RSVP) is a Transport layer protocol
designed to reserve resources across a network for an integrated services Internet. RSVP does not transport
application data but is rather an Internet control protocol, like ICMP, IGMP, or routing protocols. RSVP provides
receiver-initiated setup of resource reservations for multicast or unicast data flows with scaling and robustness.
RSVP can be used by either hosts or routers to request or deliver specific levels of quality of service (QoS) for
application data streams. RSVP defines how applications place reservations and how they can leave the
reserved resources once the need for them has ended. RSVP operation will generally result in resources being
reserved in each node along a path.
Answer option C is incorrect. A remote procedure call (RPC) hides the details of the network by using the
common procedure call mechanism familiar to every programmer. Like any ordinary procedure, RPC is also
synchronous and parameters are passed to it. A process of the client calls a function on a remote server and
remains suspended until it gets back the results.
Answer option D is incorrect. LWAPP (Lightweight Access Point Protocol) is a protocol used to control multiple
Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring, or
troubleshooting a large network. This also allows network administrators to closely analyze the network.

EGP stands for Exterior Gateway Protocol. It is used for exchanging routing information between two gateways in a network of autonomous systems. This protocol depends upon periodic polling with proper acknowledgements to confirm that network connections are up and running, and to request for routing updates. Each router requests its neighbor at an interval of 120 to 480 seconds, for sending the routing table updates. The neighbor host then responds by sending its routing table. EGP-2 is the latest version of EGP. Answer option B is incorrect. Internet Control Message Protocol (ICMP) is a maintenance protocol that allows routers and host computers to swap basic control information when data is sent from one computer to another. It is generally considered a part of the IP layer. It allows the computers on a network to share error and status information. An ICMP message, which is encapsulated within an IP datagram, is very useful to troubleshoot the network connectivity and can be routed throughout the Internet. Answer option A is incorrect. Internet Group Management Protocol (IGMP) is a communication protocol that multicasts messages and information among all member devices in an IP multicast group. However, multicast traffic is sent to a single MAC address but is processed by multiple hosts. It can be effectively used for gaming and showing online videos. IGMP is vulnerable to network attacks. Answer option D is incorrect. Open Shortest Path First (OSPF) is a routing protocol that is used in large networks. Internet Engineering Task Force (IETF) designates OSPF as one of the Interior Gateway Protocols. A host uses OSPF to obtain a change in the routing table and to immediately multicast updated information to all the other hosts in the network.

A cold site provides an office space, and in some cases basic equipment. However, you will need to restore your data to that equipment in order to use it. This is a much less expensive solution than the hot site. Answer option C is incorrect. A hot site has equipment installed, configured and ready to use. This may make disaster recovery much faster, but will also be more expensive. And a school district can afford to be down for several hours before resuming IT operations, so the less expensive option is more appropriate. Answer option A is incorrect. A warm site is between a hot and cold site. It has some equipment ready and connectivity ready. However, it is still significantly more expensive than a cold site, and not necessary for this scenario. Answer option D is incorrect. Off site is not any type of backup site terminology.
