NO.1 Which of the following security architecture elements also has sniffer functionality? (Select
TWO).
A. SSL accelerator
B. IPS
C. WAP
D. IDS
E. HSM
Answer: B,D
Explanation:
Sniffer functionality means the ability to capture and analyze the content of data packets as they
are transmitted across the network.
IDS and IPS systems perform their functions by capturing and analyzing the content of data
packets.
An intrusion detection system (IDS) is a device or software application that monitors network or
system activities for malicious activities or policy violations and produces reports to a management
station. IDS come in a variety of "flavors" and approach the goal of detecting suspicious traffic in
different ways. There are network based (NIDS) and host based (HIDS) intrusion detection
systems. Some systems may attempt to stop an intrusion attempt but this is neither required nor
expected of a monitoring system. Intrusion detection and prevention systems (IDPS) are primarily
focused on identifying possible incidents, logging information about them, and reporting attempts.
In addition, organizations use IDPSes for other purposes, such as identifying problems with
security policies, documenting existing threats and deterring individuals from violating security
policies. IDPSes have become a necessary addition to the security infrastructure of nearly every
organization.
IDPSes typically record information related to observed events, notify security administrators of
important observed events and produce reports. Many IDPSes can also respond to a detected
threat by attempting to prevent it from succeeding. They use several response techniques, which
involve the IDPS stopping the attack itself, changing the security environment (e.g. reconfiguring a
firewall) or changing the attack's content.
NO.2 A team of firewall administrators have access to a `master password list' containing service
account passwords. Which of the following BEST protects the master password list?
A. Full disk encryption
B. File encryption
C. Password hashing
D. USB encryption
Answer: B

Explanation:
File encryption can be used to protect the contents of individual files. It uses randomly generated
symmetric encryption keys for the file and stores the key in an encrypted form using the user's public
key on the encrypted file.
NO.3 Which of the following provides data the best fault tolerance at the LOWEST cost?
A. Server virtualization
B. Clustering
C. Load balancing
D. RAID 6
Answer: D
JK0-022 IT자격증시험
Explanation:
RAID, or redundant array of independent disks (RAID). RAID allows your existing servers to have more
than one hard drive so that if the main hard drive fails, the system keeps functioning. RAID can
achieve fault tolerance using software which can be done using the existing hardware and software
thus representing the lowest cost option.
NO.4 The main corporate website has a service level agreement that requires availability 100% of the
time, even in the case of a disaster. Which of the following would be required to meet this demand?
A. Cold site implementation for the datacenter
B. Warm site implementation for the datacenter
C. Geographically disparate site redundant datacenter
D. Localized clustering of the datacenter
Answer: C

Explanation:
Data backups, redundant systems, and disaster recovery plans all support availability. AN in this case
a geographically disparate site redundant datacenter represents 100% availability regardless of
whether a disaster event occurs.
