CREST CPSA EVALUATION EXAMS QUESTIONS AND
ANSWERS FIRM A+
✔✔DNS Record Types - ✔✔SOA- Start of Auth Record
MX- Mail Exchange
TXT- Text Record
A- Address (IPv4)
AAAA- Address (IPv6)
NS - Name Server
PTR - Pointer Record
HINFO - Description of computer / OS
CNAME - Canonical Name
✔✔Start of Authority (SOA) Record - ✔✔Every zone file must include a ___ record to
identify the name server that's primarily responsible for the database segments it
manages.
✔✔Mail Exchanger (MX) Record - ✔✔A record used by e-mail servers for determining
the host names of servers responsible for handling a domain's incoming e-mail.
✔✔A / AAAA Record - ✔✔IP Address
✔✔Name Server (NS) Record - ✔✔announces the authoritative name servers for a
particular zone who will answer queries for their supported zone
✔✔Pointer Record (PTR) - ✔✔A record that points IP addresses/Canonical to host
names. See also Reverse Lookup Zone.
✔✔CNAME (Canonical name record) - ✔✔A type of DNS data record that holds
alternative names for a host.
✔✔Network Protocols - ✔✔ARP
DHCP
CDP
HSRP
VRRP
VTP
STP
TACACS
✔✔Cisco Discovery Protocol (CDP) - ✔✔a Cisco proprietary Layer 2 protocol to gather
information about neighboring Cisco devices
, ✔✔HSRP (Hot Standby Router Protocol) - ✔✔This is exclusive to Cisco and allows a
default router address to be configured to be used in the event that the primary router
fails.
✔✔VRRP (Virtual Router Redundancy Protocol) - ✔✔A standard that assigns a virtual
IP address to a group of routers. At first, messages routed to the virtual IP address are
handled by the master router. If the master router fails, backup routers stand in line to
take over responsibility for the virtual IP address.
✔✔VTP (VLAN Trunking Protocol) - ✔✔Cisco's protocol for exchanging VLAN
information over trunks. Allows one switch on a network to centrally manage all VLANs.
✔✔STP (Spanning Tree Protocol) - ✔✔A Layer 2 protocol that is used for routing and
prevents network loops by adopting a dynamic routing method.
✔✔WEP - ✔✔Wired Equivalent Privacy
✔✔Wired Equivalent Privacy (WEP) - ✔✔An IEEE 802.11 security protocol designed to
ensure that only authorized parties can view transmitted wireless information. Has
significant vulnerabilities and is not considered secure.
✔✔WPA - ✔✔Wireless Protected Access
✔✔Wireless Protected Access (WPA) - ✔✔The 802.11 security method created as a
stopgap between WEP and 802.11i.
WPA2 uses AES Encryption
✔✔EAP (Extensible Authentication Protocol) - ✔✔A protocol that enables systems to
use hardware-based identifiers, such as fingerprint scanners or smart card readers, for
authentication.
✔✔EAP - ✔✔Extensible Authentication Protocol
✔✔LEAP - ✔✔Lightweight Extensible Authentication Protocol
✔✔PEAP - ✔✔Protected Extensible Authentication Protocol
✔✔nbtstat - ✔✔A Windows utility that is used to view and
manage NetBIOS name cache information.
✔✔Global Catalog Server - ✔✔A domain controller that holds a subset of the
information in all domain partitions for the entire Active Directory forest.
