What is the framing specification used for transmitting digital signals at 1.544 Mbps on a T1 facility?

Correct Answer:B
Digital Signal level 1 (DS-1) is the framing specification used for transmitting digital signals at 1.544 Mbps on a T1 facility. DS-0 is the framing specification used in transmitting digital signals over a single 64 Kbps channel over a T1 facility. DS-3 is the framing specification used for transmitting digital signals at 44.736 Mbps on a T3 facility. DS-2 is not a defined framing specification.

Which of the following best defines a Computer Security Incident Response Team (CSIRT)?

Correct Answer:C
RFC 2828 (Internet Security Glossary) defines a Computer Security Incident Response Team (CSIRT) as an organization that coordinates and supports the response to security incidents that involves sites within a defined constituency. This is the proper definition for the CSIRT. To be considered a CSIRT, an organization must provide a secure channel for receiving reports about suspected security incidents, provide assistance to members of its constituency in handling the incidents and disseminate incident-related information to its constituency and other involved parties. Security-related incidents do not necessarily have to be reported to the authorities.

Which of the following is NOT a defined ISO basic task related to network management?

Correct Answer:D
ISO has defined five basic tasks related to network management :
Fault management: Detects the devices that present some kind of fault. Configuration management: Allows users to know, define and change remotely the configuration of any device.
Accounting resources: Holds the records of the resource usage in the WAN. Performance management: Monitors usage levels and sets alarms when a threshold has been surpassed.
Security management: Detects suspicious traffic or users and generates alarms accordingly.

Which of the following is NOT a transaction redundancy implementation?

Correct Answer:A
Three concepts are used to create a level of fault tolerance and redundancy in transaction processing.
They are Electronic vaulting, remote journaling and database shadowing provide redundancy at the transaction level.
Electronic vaulting is accomplished by backing up system data over a network. The backup location is usually at a separate geographical location known as the vault site. Vaulting can be used as a mirror or a backup mechanism using the standard incremental or differential backup cycle. Changes to the host system are sent to the vault server in real-time when the backup method is implemented as a mirror. If vaulting updates are recorded in real-time, then it will be necessary to perform regular backups at the off-site location to provide recovery services due to inadvertent or malicious alterations to user or system data.
Journaling or Remote Journaling is another technique used by database management systems to provide redundancy for their transactions. When a transaction is completed, the database management system duplicates the journal entry at a remote location. The journal provides sufficient detail for the transaction to be replayed on the remote system. This provides for database recovery in the event that the database becomes corrupted or unavailable.
There are also additional redundancy options available within application and database software platforms. For example, database shadowing may be used where a database management system updates records in multiple locations. This technique updates an entire copy of the database at a remote location.

The Information Technology Security Evaluation Criteria (ITSEC) was written to address which of the following that the Orange Book did not address?

Correct Answer:C
TCSEC focused on confidentiality while ITSEC added integrity and availability as security goals.
The following answers are incorrect:
integrity and confidentiality. Is incorrect because TCSEC addressed confidentiality. confidentiality and availability. Is incorrect because TCSEC addressed confidentiality. none of the above. Is incorrect because ITSEC added integrity and availability as security goals.

Which of the following category of UTP cables is specified to be able to handle gigabit Ethernet (1 Gbps) according to the EIA/TIA-568-B standards?

Correct Answer:A
Categories 1 through 6 are based on the EIA/TIA-568-B standards.
On the newer wiring for LANs is CAT5e, an improved version of CAT5 which used to be outside of the standard, for more information on twisted pair, please see: twisted pair.
Category Cable Type Mhz Usage Speed
=============================================
CAT1 UTP Analog voice, Plain Old Telephone System (POTS) CAT2 UTP 4 Mbps on Token Ring, also used on Arcnet networks CAT3 UTP, ScTP, STP 16 MHz 10 Mbps
CAT4 UTP, ScTP, STP 20 MHz 16 Mbps on Token Ring Networks
CAT5 UTP, ScTP, STP 100 MHz 100 Mbps on ethernet, 155 Mbps on ATM
CAT5e UTP, ScTP, STP 100 MHz 1 Gbps (out of standard version, improved version of CAT5)
CAT6 UTP, ScTP, STP 250 MHz 10 Gbps CAT7 ScTP, STP 600 M 100 Gbps
Category 6 has a minumum of 250 MHz of bandwidth. Allowing 10/100/1000 use with up to 100 meter cable length, along with 10GbE over shorter distances.
Category 6a or Augmented Category 6 has a minimum of 500 MHz of bandwidth. It is the newest standard and allows up to 10GbE with a length up to 100m.
Category 7 is a future cabling standard that should allow for up to 100GbE over 100 meters of cable. Expected availability is in 2013. It has not been approved as a cable standard, and anyone now selling you Cat. 7 cable is fooling you.
