193. Match each component of a WAN connection to its description. (Not all options are used.) 194. What type of trafÏc is described as being able to tolerate a certain amount of latency, jitter, and loss without any noticeable effects?  voice  video  data 195. What term describes adding a value to the packet header, as close to the source as possible, so that the packet matches a defined policy?  policing  trafÏc marking  weighted random early detection (WRED)  traffic shaping  tail drop 196. Which three trafÏc-related factors would influence selecting a particular WAN link type? (Choose three.)  cost of the link  amount of trafÏc  distance between sites  reliability  security needs  type of trafÏc Explanation: The traffic-related factors that influence selecting a particular WAN link type include the type of traffic, amount of traffic, quality requirements, and security requirements. Quality requirements include ensuring that traffic that cannot tolerate delay gets priority treatment as well as important business transactional traffic. 197. What command would be used as part of configuring NAT or PAT to link the inside local addresses to the pool of addresses available for PAT translation?  ip nat inside source list ACCTNG pool POOL-STAT  ip nat translation timeout 36000  ip nat inside source list 14 pool POOL-STAT overload  ip nat inside source static 172.19.89.13 198.133.219.65 198. What protocol is a vendor-neutral Layer 2 discovery protocol that must be configured separately to transmit and receive information packets?  SNMP  MPLS  LLDP  NTP 199. An ACL is applied inbound on a router interface. The ACL consists of a single entry: access-list 210 permit tcp 172.18.20.0 0.0.0.31 172.18.20.32 0.0.0.31 eq ftp . If a packet with a source address of 172.18.20.55, a destination address of 172.18.20.3, and a protocol of 21 is received on the interface, is the packet permitted or denied?  permitted  denied 200. Refer to the exhibit. Corporate policy demands that access to the server network be restricted to internal employees only. What is the best ACL type and placement to use in this situation? Corporate policy demands that access to the server network be restricted to internal employees only. What is the best ACL type and placement to use in this situation  extended ACL outbound on R2 S0/0/1  standard ACL outbound on R2 S0/0/0  standard ACL inbound on R2 WAN interface connecting to the internet  extended ACL inbound on R2 S0/0/0 201. A technician is working on a Layer 2 switch and notices that a %CDP-4DUPLEX_MISMATCH message keeps appearing for port G0/5. What command should the technician issue on the switch to start the troubleshooting process?  show cdp neighbors  show ip interface brief  show interface g0/5  show cdp 202. Which virtual resource would be installed on a network server to provide direct access to hardware resources?  VMware Fusion  a management console  a dedicated VLAN  a Type 1 hypervisor Explanation: Type 1 hypervisors, the hypervisor is installed directly on the server or networking hardware. Then, instances of an OS are installed on the hypervisor, as shown in the figure. Type 1 hypervisors have direct access to the hardware resources. Therefore, they are more efficient than hosted architectures. Type 1 hypervisors improve scalability, performance, and robustness. 203. Refer to the exhibit. A network administrator has configured a standard ACL to permit only the two LAN networks attached to R1 to access the network that connects to R2 G0/1 interface. When following the best practices, in what location should the standard ACL be applied? Enterprise Networking, Security, and Automation ( Version 7.00) – ENSA Final Exam  R2 G0/1 inbound  R2 S0/0/1 outbound  R1 S0/0/0 outbound  R2 G0/1 outbound  R2 G0/0 outbound 204. Which OSPF database is identical on all converged routers within the same OSPF area?  neighbor  forwarding  link-state  adjacency Explanation: Regardless of which OSPF area a router resides in, the adjacency database, routing table, and forwarding database are unique for each router. The link-state database lists information about all other routers within an area and is identical across all OSPF routers participating in that area. 205. What are two features to consider when creating a named ACL? (Choose two.)  Use alphanumeric characters if needed.  Use special characters, such as ! or * to show the importance of the ACL.  Modify the ACL using a text editor.  Be descriptive when creating the ACL name.  Use a space for ease of reading to separate the name from the description Explanation: The following summarizes the rules to follow for named ACLs:  Assign a name to identify the purpose of the ACL.  Names can contain alphanumeric characters.  Names cannot contain spaces or punctuation.  It is suggested that the name be written in CAPITAL LETTERS.  Entries can be added or deleted within the ACL. 206. Match the RESTful API method to CRUD function. Match the RESTful API method to CRUD function. 207. What type of trafÏc is described as requiring at least 384 Kbps of bandwidth?  voice  data  video 208. Which step in the link-state routing process is described by a router inserting best paths into the routing table?  declaring a neighbor to be inaccessible  executing the SPF algorithm  load balancing equal-cost paths  choosing the best route 209. Anycompany has decided to reduce its environmental footprint by reducing energy costs, moving to a smaller facility, and promoting telecommuting. What service or technology would support this requirement?  data center  virtualization  cloud services  dedicated servers 210. Which QoS technique smooths packet output rate?  policing  shaping  weighted random early detection  Integrated Services (IntServ)  marking 211. Refer to the exhibit. The company has provided IP phones to employees on the 192.168.10.0/24 network and the voice trafÏc will need priority over data trafÏc. What is the best ACL type and placement to use in this situation?  extended ACL inbound on R1 G0/0  extended ACL outbound on R2 WAN interface towards the internet  extended ACL outbound on R2 S0/0/1  extended ACLs inbound on R1 G0/0 and G0/1 Explanation: Standard ACLs permit or deny packets based only on the source IPv4 address. Because all traffic types are permitted or denied, standard ACLs should be located as close to the destination as possible. Extended ACLs permit or deny packets based on the source IPv4 address and destination IPv4 address, protocol type, source and destination TCP or UDP ports and more. Because the filtering of extended ACLs is so specific, extended ACLs should be located as close as possible to the source of the traffic to be filtered. Undesirable traffic is denied close to the source network without crossing the network infrastructure. 212. A network technician is configuring SNMPv3 and has set a security level of SNMPv3 authPriv. What is a feature of using this level?  authenticates a packet by using the SHA algorithm only  authenticates a packet by a string match of the username or community string  authenticates a packet by using either the HMAC with MD5 method or the SHA method  authenticates a packet by using either the HMAC MD5 or HMAC SHA algorithms and a username
