Excessive broadcasts are generally a symptom of a problem at which layer? • physical • data link • network • transport 3. What is one example of a physical layer problem? • incorrect encapsulation • incorrect STP configuration • incorrect ARP mapping • incorrect clock rate 4. Which two components should be taken into consideration when establishing a network baseline? (Choose two.) • information about the network design • IP addressing allocation on the network • requirements about the service provider setup • requirements for access control lists to regulate traffic • expected performance under normal operating conditions 5.

1. Why is it important to record baseline measurements of a prototype network? • Test results show security weaknesses after the baseline tests are run. • The baseline is the point at which the network is operating at its fullest potential. • Baseline measurements define a point at which network traffic has exceeded the designed capabilities of the network. • Test results are compared to the baseline to see how the test conditions increase processor use or decrease available bandwidth. 2. Refer to the exhibit. During prototype testing, verification of VLAN connectivity is being performed. Based on the information shown, what command produced the output? • show spanning-tree • show interfaces trunk* • show cdp neighbors • show interfaces • show ip interface brief 3. How do designers decide which network functions need to be included in the prototype test? • They select the functions that align with the business goals. • They select the functions that occur at the … [Read more...]

1. Which two statements about DSL are true? (Choose two.) • users are on a shared medium • uses RF signal transmission • local loop can be up to 3.5 miles (5.5km) • physical and data link layers are defined by DOCSIS • user connections are aggregated at a DSLAM located at the CO 2. Which two Layer 1 requirements are outlined in the Data-over-Cable Service Interface Specification (DOCSIS)? (Choose two.) • channel widths • access method • maximum data rate • modulation techniques • compression techniques 3. Which two statements are valid solutions for a cable ISP to reduce congestion for users? (Choose two.) • use higher RF frequencies • allocate an additional channel • subdivide the network to reduce users on each segment • reduce the length of the local loop to 5.5 kilometers or less • use filters and splitters at the customer site to separate voice from data traffic 4. A technician has been asked to configure a broadband connection for a teleworker. … [Read more...]

1. By default, how is IP traffic filtered in a Cisco router? • blocked in and out of all interfaces • blocked on all inbound interfaces, but permitted on all outbound interfaces • permitted in and out of all interfaces • blocked on all outbound interfaces, but permitted on all inbound interfaces 2. Which three parameters can ACLs use to filter traffic? (Choose three.) • packet size • protocol suite • source address • destination address • source router interface • destination router interface 3. How do Cisco standard ACLs filter traffic? • by destination UDP port • by protocol type • by source IP address • by source UDP port • by destination IP address 4. Which two statements are correct about extended ACLs? (Choose two) • Extended ACLs use a number range from 1-99. • Extended ACLs end with an implicit permit statement. • Extended ACLs evaluate the source and destination addresses. • Port numbers can be used to add greater definition to an … [Read more...]

1. Which two statements are true regarding network security? (Choose two.) • Securing a network against internal threats is a lower priority because company employees represent a low security risk. • Both experienced hackers who are capable of writing their own exploit code and inexperienced individuals who  download exploits from the Internet pose a serious threat to network security. • Assuming a company locates its web server outside the firewall and has adequate backups of the web server, no further  security measures are needed to protect the web server because no harm can come from it being hacked. • Established network operating systems like UNIX and network protocols like TCP/IP can be used with their default settings because they have no inherent security weaknesses. • Protecting network devices from physical damage caused by water or electricity is a necessary part of the security  policy. 2. Which two statements are true about network attacks? (Choose two.) • … [Read more...]
