What do unique local ipv6 unicast prefix always begin with? -
correct answer FD or FC
Because the first 7 bits of a unique local unicast address are
always 1111110
They can not be aggregatable nor summarized.
What is the address range if a host IP can not obtain a network
address via DHCP? - correct answer 169.254.1.0 to
169.254.254.255
What protocol uses UDP and TCP? - correct answer DNS
(Domain Name System)
Link local addresses are unicast addresses used for
communication over a __________ link - correct answer single
Link local addresses in ipv6 are used to form what? - correct
answer Neighbor adjacencies
Global ipv6 unicast addresses, also known as aggregable global
address, do they form neighbor adjacency? - correct answer
NO. They do NOT form neighbor adjacency.
Ipv6 multicast address for Link-local - correct answer FF02::/16
Ipv6 multicast address for Site-local - correct answer FF05::/16
Ipv6 multicast address for unicast site-local - correct answer
FC00::/7
Ipv6 multicast address for global address - correct answer
FF0E::/16
Are unicast link local ipv6 addreses routable? - correct answer
NO.
Used for neighbor discovery
,What is HDLC? - correct answer The High-Level Data-Link
Control (HDLC) protocol is a populare ISO-standard, bit-oriented,
Data Link layer protocol. It specifies an encapsulation method for
data on synchronous serial data links using frame characters and
checksums. HDLC is a point-to-point protocol used on leased
lines. No authentication can be used with HDLC.
What is the difference between HDLC and PPP? - correct
answer The major difference between HDLC and PPP , the PPP
protocol performs better than HDLC because there is no
compulsion of using the Cisco devices in both the ends, which
means these are interoperable. PPP also supports multiple
protocols and support authentication.
What is PPP? - correct answer Point-to-Point Protocol (PPP) is a
Data Link layer protocol that can be used over either
asynchronous serial (dial-up) or synchronous serial (ISDN)
media. It uses Link Control Protocol (LCP) to build and maintain
data-link connections. Network Control Protocol (NCP) is used to
allow multiple Network layer protocols (routed protocols) to be
used on a point-to-point connection. The basic purpose of PPP is
to transport layer 3 packets across a Data Link layer point-to-
point link, and it's nonproprietary. The PPP protocol stack is
specified at the Physical and Data Link layers only.
In 802.11 wireless topology, what is BSS in Infrastructure? -
correct answer Basic Service Set;
Consist of a single AP interconnecting all associated wireless
clients. The radius of which it covers in it wireless range is called
a Basic Service Area (BSA).
, Layer 2 MAC address of the AP is used to uniquely ID each BSS
which is called a Basic Service Set Identifier (BSSID).
In 802.11 wireless topology, what is ESS in infrastructure? -
correct answer Extended Service Set
ESS is ID by a SSID and each BSS is ID by its BSSID.
When you need more coverage, two or more BSS can join
through a common distribution system (DS) into an ESS. The
whole covered area is called an Extended Service Area (ESA).
A client in one BSA can now communicate with other clients in
another BSA within the same ESS. Like a roaming cell phone
user may move from one BSA to another and it would be
seamless
Since WLAN are half-duplex, what do we use to avoid collision? -
correct answer (CSMA/CA) carrier sense multiple access with
collision avoidance.
What is the port number of RADIUS? - correct answer 1812 for
authentication
1813 for accouting
1645/1646 for UDP ports
AD of directly connected routing - correct answer 0
AD of static route - correct answer 1
AD of internal EIGRP - correct answer 90
