A company that makes Computer Assisted Design (CAD) software has, within its application, some utility classes that are used to perform 3D rendering tasks. The company‘s chief scientist has just improved the performance of one of the utility classes‘ key rendering algorithms, and has assigned a programmer to replace the old algorithm with the new algorithm. When the programmer begins researching the utility classes, she is happy to discover that the algorithm to be replaced exists in only one class. The programmer reviews that class‘s API, and replaces the old algorithm with the new algorithm, being careful that her changes adhere strictly to the class‘s API. Once testing has begun, the programmer discovers that other classes that use the class she changed are no longer working properly.What design flaw is most likely the cause of these new bugs?（）A.InheritanceB.Tight couplingC.Low cohesionD.High cohesionE.Loose couplingF.Object immutability
What is the purpose of the magic number in an LCP negotiation?() A.It is used to detect loops.B.It is an interface identifier.C.It selects a compression algorithm.D.It specifies the transmission media.
The ERX Edge Router in your Bridged 1483 network has multiple external DHCP servers configured.During discovery, which algorithm does the router use to decide which DHCP server to send packets to?() A. direct modeB. round robinC. weighted round robinD. No algorithm is used.
The enable secret password appears as an MD5 hash in a router’s configuration file， whereas the enablepassword is not hashed （or encrypted， if the password-encryption service is not enabled）. What is thereason that Cisco still support the use of both enable secret and enable passwords in a router’sconfiguration？（）A、The enable password is present for backward compatibility.B、Because the enable secret password is a hash， it cannot be decrypted. Therefore， the enable password is used to match the password that was entered， and the enable secret is used to verify that the enablepassword has not been modified since the hash was generated.C、The enable password is considered to be a router’s public key， whereas the enable secret password is considered to be a router’s private key.D、The enable password is used for IKE Phase I， whereas the enable secret password is used for IKE Phase II.

多选题What are three security problems with Wi-Fi Protected Access （WPA）？（）AWPA is based on the outdated IEEE 802.11i standard.BWPA uses RSN，which uses the same base encryption algorithm as RC4.CWPA requires a hardware upgrade that may not be supported by all vendors.DWPA uses TKIP，which uses the same base encryption algorithm as WEP.EWPA is susceptible to a DoS attack when it receives two packets in quick succession with bad MICs，forcing the AP to shut down the entire Basic Service Set （BSS） for one minute.FWPA is susceptible to a security weakness when preshared keys are used.
