40、s been told to install doors that provide failsafe, fail-secure, and fail-soft protection. Which of the following statements is true about secure door types?（分数：2.00）A.Fail-soft defaults to the sensitivity of the area. B.Fail-safe defaults to locked.C.Fail-secure defaults to unlocked.D.Fail-secure d

41、efaults to double locked.解析：解析：A 正确。带自动锁的门可以配置成故障保护(fail-secure)型、故障安全型(fail-safe)或故障弱化型(fail-soft)。故障弱化指的是根据某个区域内的数据和系统(比如某人在这幢大楼的特定区域内工作)的敏感度，默认设置为上锁或解锁。故障弱化系统的目的是以故障的方式尽可能多地保护数据和功能。 B 不正确。因为故障安全(fail-safe)并非默认为上锁。故障安全设置是指一旦发生了影响自动上锁系统的电力中断，那么门默认为解锁。故障安全的设置直接与对人的保护有关。如果人们在一个区域内工作，一旦该区域发生大火或者断电，把人锁

42、在里面可不是个好主意。 C 不正确。因为故障保护(fail-secure)并非默认为解锁。故障保护配置是指一旦电力出现问题，门默认为上锁。注意不要混淆故障保护和故障安全。你可以这么想：如果故障保护锁出现故障，门是安全的，即门被锁住；如果故障安全锁出故障，那么它所保护的人是安全的，因为人们可以通过门离开。 D 不正确。因为故障保护并非默认为双重上锁。在故障保护配置下，如果电力出现问题，门便会锁上。2.Windows can have different glazing materials. What type of window may be prohibited by fire codes b

43、ecause of its combustibility?（分数：2.00）A.TemperedB.Polycarbonate acrylic C.Glass-clad polycarbonateD.Laminated解析：解析：B 正确。在设计和构建一个设施时，从物理安全角度来说，窗户(Windows)是需要处理的项日之一。除了要考虑它们的布局位置和入侵者是否能接近外，还应该考虑以下问题：半透明或不透明的需求、报警器和是否防碎等。窗户应该位于合适的位置(既要考虑安全性又要考虑美观性)，其框架也应该具有适当强度，合适的玻璃材质，可能还需要一个保护罩。用于窗体上的玻璃材料可以是标准的、钢化的、亚

44、克力的或夹线玻璃，也可以是层压玻璃。聚碳酸酯亚克力要比标准玻璃、锻压玻璃和普通亚克力玻璃结实。与普通亚克力一样，聚碳酸酯是由一种透明颦料制成的。然而，由于它的可燃性，消防条例中明文禁止使用该材质。不要混淆聚碳酸酯亚克力和玻璃钢，后者是现今使用的最结实的窗口材料，它能防火、防化学品腐蚀、防碎等。 A 不正确。因为钢化玻璃不可燃。钢化玻璃是通过把玻璃加热，然后再突然冷却而制成的。这样增加了它的机械强度，使其更能抗压，难以打破。它的强度是普通玻璃的 5到 7倍。钢化玻璃即使碎了，也只是碎成小块，而不是碎成带尖的碎片。这样，与普通玻璃相比，钢化玻璃造成伤害的可能性更小。因为钢化玻璃有较厚的安全性和强度

45、，所以经常用于制造汽车玻璃、玻璃门和桌子以及厨具等。 C 不正确。因为玻璃钢能抵抗很多威胁，包括火。因此，它们不同于因可燃性而被消防条例禁止使用的聚碳酸酯亚克力，后者是由塑料制成的。玻璃钢是最结实的窗口材料，因此它也比其他玻璃材质贵得多。这种材料应该用于面临威胁最大的区域。 D 不正确。因为层压玻璃窗不可燃。层压玻璃有两层，其中问有一层塑料薄膜。添加的这层塑料薄膜使之更难被打破。当玻璃受到攻击开裂时，破裂的形状有如蜘蛛网。与其他类型的玻璃相比，层压玻璃可以有不同厚度。玻璃越厚(更多的玻璃和塑料)越难打破。层压玻璃窗经常用于汽车挡风玻璃、店铺外窗和天窗。3.As with logical acc

46、ess controls, audit logs should be produced and monitored for physical access controls. Which of the following statements is correct about auditing physical access?（分数：2.00）A.Unsuccessful access attempts should be logged but only need to be reviewed by a security guard.B.Only successful access attem

47、pts should be logged and reviewed.C.Only unsuccessful access attempts during unauthorized hours should be logged and reviewed.D.All unsuccessful access attempts should be logged and reviewed. 解析：解析：D 正确。物理访问控制系统可以使用软件和审计特征来生成访问尝试有关的审计跟踪或访问日志。下列信息应该被记录臼志并审核：访问尝试发生的口期和时间、访问尝试的入口点、尝试访问时使用的用户 ID以及任何未成功的

48、访问，特别这些访问尝试是否出现在未经授权的时段内。 A 不正确。因为正如计算机产生的审计口志一样，访问日志只在人们真正审核它们之时才有用处。安全人员需要审核这些日志，但是安全专家或者设备经理也应该定期审核这些日志。管理层需要知道这个设备的入口点在什么地方以及谁试图使用它们。审计和访问口志是侦测控制，而不是预防控制。它们用于在事实发生之后拼凑出情形，而不是试图在第一时间防止访问尝试的发生。 B 不正确。因为未成功的访问尝试也应该被记录并审核。尽管审计并不能拒绝实体访问网络、计算机或位置的活动，但它会跟踪活动，以便安全专家警惕可疑活动的出现。这些信息可以用来指出其他控制的弱点，有助于安全人员了解什

49、么地方必须做出变更以维护这个环境中所需的安全级别。 C 不正确。因为所有未授权的访问尝试无论出现在什么时候都应该被记入日志和审核。闯入企图可以出现在任何时候。可以为物理访问控制设置一些操作参数，允许接受一定量的失败访问尝试之后再锁定用户，这是一种自定义级别。对这种信息进行审计跟踪能够提醒安全人士注意可能出现的入侵。4.Brad is installing windows on the storefront of a bank in an area known to be at risk of fires in the dry season. Which of the following is least likely to be true of the windows he is installing?（分数：2.00）A.The glass has embedded wires.B.They are made of glass-clad polycarbonate.C.The window material is acrylic glass. D.A solar window film has been added to them.解析：解析：C 正确。Brad 安装的窗户不太可能是亚克力玻璃。亚克力玻璃是由聚碳酸酯亚克力制成，虽然它
