After you deploy a new WLAN controller on your network, Which two additional tasks should you consider? (Choose two.). Configure multiple VRRP groups. Configure additional VLANs. Configure additional security policies. Deploy load balancers. Deploy POE switches.

Which two commands can you use to configure a PAgP EtherChannel? (Choose two.). channel-group 10 mode auto. channel-group 10 mode active. channel-group 10 mode desirable. channel-group 10 mode on. channel-group 10 mode passive.

Which command should you enter to configure a single port to enter an err-disabled state when it receives an infenior BPDU?. spanning-tree portfast bpduguard. spanning-tree guard root. spanning-tree portfast default. spanning-tree portfast bpdufilter.

Which two statements about single and dual-homed links are true? ( choose two.). Single-homed connections to a service provider require OSPF or EIGRP. Dual-homed connections to multiple service providers can use OSPF or EIGRP for load balancing. Single-homed connections to a service provider can use either static routing or BGP. Dual-homed connection to multiple service providers typically use BGP. Dual-homed connections to a service provider most frequently use static routing.

After you configure the ip dns spoofing command globally on a device, under which two conditions is DNS spoofing enabled on the device? (Choose two.). The DNS server queue limit id disabled. The ip host command is disabled. All configured IP name server addresses are removed. The ip dns spoofing command is disabled on the local interface. The no ip domain lookup command is configured.

Which command should you enter to verify the priority of a router in an HSRP group?. show standby. show interfaces. show sessions. show hsrp.

Which feature or method can you use to isolate physical layer problems on a serial link?. autonegotiation. protocol analyzer. loopback tests. UDLD.

Which algorithm is used for the frame check sequence in an Ethernet frame?. MD5. AES-256. CRC. SHA-1.

Which two features can you enable on a switch to capture network traffic and measure performance?(choose two). ACL. SPAN. IP SLA. STP. SNMP.

Which layer of the TCP/IP model manages the transmission of binary digits across an Ethernet cable?. network. data link. transport. physical.

Which statement about recovering a password on a Cisco router is true?. The default reset password is cisco. It requires a secure SSl/VPN connection. A factory resset is required if you forget the password. It requires physical access to the router.

What are two advantages of static routing? (Choose two.). It can be implemented easily even in large environments. It allows the administrator to control the path of traffic. It produces minimal CPU load. It allows the network to respond immediately to changes. It cannot be used to load-balance traffic over multiple links.

Which two steps must you perform on each device that is configured for IPv4 routing before you implement OSPFv3?(Choose two). configure an autonomous system number. configure a loopback interface. configure a router ID. Enable IPv6 on an interface. Enable IPv6 unicast routing.

What is the effect of PortFast on the MAC aging process?. It prevents fast aging of MAC addresses when IEEE 802.1D is in use. It prevents fast aging of MAC addresses when RSTP is in use. It ignores the MAC aging timer when RSTP is in use. It ignores the MAC aging timer when IEEE 802.1D is in use.

Which two TLVs does LLDP support ? (Choose two.). system description. port duplex. management address. native VLAN. spanning tree.

Which two circumstances can prevent two routers from establishing an EIGRP neighbor adjacency? (Choose two.). An ACL is blocking traffic from multicast address 224.0.05. Both routers have the same router ID. The routers are on different subnets. The two routers have the same autonomous system number. The routers have mismatched K values.

Which two features can dynamically assign IPv6 addresses? (Choose two.). IPv6 stateless autoconfiguration. DHCP. NHRP. IPv6 stateful autoconfiguration. ISATAP tunneling.

Which type of routing protocol operates by using first information from each device peers?. link-state protocols. distance-vector protocols. path-vector protocols. exterior gateway protocols.

According to industry best practices, which length is the recommended maximum for a Category 6 cable in a 10GBASE-T environment?. 37 meters. 300 meters. 100 meters. 55 meters.

Which two statements about floating static routes are true? (Choose two). They are routes to the exact /32 destination address. They are used when a route to the destination network is missing. They have a higher administrative distance than the default static route administrative distance. They are used as back-up routes when the primary route goes down. They are dynamic routes that are learned from a server.

Which two IP SLA operations can you use to measure the end-to-end response time for all IP traffic between a Cisco router and an end device ?(choose two). ICMP path echo. UDP echo. ICMP path jitter. UDP jitter. TCP connect. ICMP echo.
